The Smart RVer: DIY RV Maintenance and Repair

Summary/IntroDoes your RV water pump run when nobody is using water, cycle rapidly at the faucet, or struggle to shut off? Before you buy a replacement, find out what the pump is telling you.In this episode of The Smart RVer Podcast, Eric Stark walks you through practical checks to help separate a pump problem from a plumbing problem. Learn where to look for hidden leaks, how winterizing valves and intake restrictions can affect operation, and why air entering a connection may cause trouble without leaving a puddle. Eric also covers the inlet strainer, electrical supply, pressure controls, and accumulator considerations.With a flashlight, a few paper towels, and a methodical approach, you can narrow down the cause and make a better repair decision. Download the “Why Is My RV Water Pump Running?” checklist from The Smart RVer website and follow along.Show NotesAn RV water pump that keeps cycling can be annoying—but it can also be warning you about a plumbing problem. In episode 215, Eric Stark explains how to follow the symptoms before spending money on a replacement pump.Start With What the Pump Is DoingThe first step is identifying when the problem occurs:The pump briefly runs with every fixture closed.It rapidly switches on and off while a faucet is open.It keeps running after you close the faucet.Water sputters or flows poorly.The pump sounds unusually loud.These symptoms lead to different checks. Describing the behavior clearly helps you choose where to begin.Check the Water Supply and Look for LeaksConfirm that the fresh tank has water and that winterizing, tank-fill, and bypass valves are positioned correctly. Inspect accessible plumbing under sinks, around the toilet, behind service panels, and near the water heater, exterior shower, and low-point drains.A flashlight and dry paper towels can help reveal small leaks. If everything appears dry, keep investigating: concealed leaks and water leaking backward through the pump’s internal valves are still possibilities.Inspect the Intake SideA restricted supply line, dirty inlet strainer, or connection that draws air can cause sputtering, poor flow, and difficulty building pressure. Eric explains why a suction-side air leak may not leave visible water behind.Before opening the strainer or disconnecting plumbing, turn the pump off, disconnect city water, and relieve system pressure.Consider Power, Pressure Controls, and the AccumulatorThe motor running does not prove the pump has adequate electrical power. Checking voltage at the pump while it operates can help identify a supply problem.Pressure-switch settings and bypass controls require model-specific guidance. Record original settings and follow the manufacturer’s procedure before making any adjustments. If your system has an accumulator, check its condition and setup according to its instructions.Decide Whether to Repair or ReplaceA new pump will not fix a leak, incorrect valve position, restricted intake, or poor electrical connection. Work through those possibilities before deciding the pump has failed.Document the symptoms, photograph the model label, and consult the correct manual. If testing points to internal failure or performance continues to decline, evaluate repair or replacement. Some low-flow cycling may be normal, but unexplained cycling with every fixture closed deserves further investigation.Eric also discusses carrying spare plumbing fittings and whether a spare pump makes sense for trips into remote areas.Download the Companion ChecklistGet the “Why Is My RV Water Pump Running?” checklist at TheSmartRVer.com.

Summary/Intro:Your Dometic RV refrigerator isn’t cooling—but does that mean you need a circuit board, a heating element, or something else? Before you start buying parts, let’s narrow down the problem.In this episode of The Smart RVer Podcast, I walk through troubleshooting Dometic DM series absorption refrigerators. We’ll start with the basics: 12-volt control power, fuses, breakers, and which heat source is actually operating. Then we’ll separate electric problems from propane problems so you have a clearer idea of what to check next.I also explain why cooling time, thermometer readings, and a few written observations can help you avoid an expensive guess. Whether you’re doing basic checks yourself or preparing to talk with a technician, the goal is the same: gather useful evidence before spending money on parts.Show Notes:Dometic DM Refrigerator Not Cooling? Narrow Down the Problem Before Buying PartsA warm refrigerator tells you something is wrong. It doesn’t tell you which part failed. In this episode, Eric Stark explains how to troubleshoot a Dometic DM refrigerator with a clear sequence of checks.The discussion focuses on the DM2672, DM2872, DM2682, and DM2882 absorption refrigerators, helping you identify the symptom, confirm the operating heat source, and decide what needs further testing.Understand the basics firstAbsorption refrigerators use heat to produce cooling. These models can use propane or a 120-volt electric heating element, while their electronic controls require 12-volt DC power on either source. AUTO mode can switch to propane when AC power is unavailable, so being plugged in doesn’t prove the refrigerator is cooling on electric.Follow the symptomWon’t turn on: Start with the DC supply, identified fuses, and accessible connections before blaming the controls.Cools on propane but not electric: Investigate the AC supply and electric heating path before ordering a heating element.Cools on electric but not propane: Record ignition attempts, CHECK indicator behavior, and whether a flame starts and stays lit.Runs but cools poorly: Review cooling time, level parking, ventilation, door closure, and temperature readings in both compartments.Works intermittently: Keep a record of operating mode, weather, temperatures, and when the problem occurs.Give it time—and measure the resultsAllow an appropriate cooling period according to your model’s manual. Use thermometers in both compartments rather than judging performance by touch. Start your pre-trip checks early enough to identify a problem and address it before departure.Collect the information that makes diagnosis easierRecord the model, product code, and serial number. Photograph the data label and control panel, and write down the symptoms before restarting the refrigerator. Use the correct service manual for component specifications and diagnostic procedures.Know when to get helpKeep owner checks within your abilities. Leave live 120-volt testing, gas-pressure testing, and gas-system repairs to a qualified technician. Never bypass safety devices or keep operating a refrigerator if you see signs of a leak or hazardous failure.Companion resourcesVisit this episode’s website post for the Dometic DM Refrigerator Troubleshooting Checklist, the Americana II vs. Americana II Plus infographic, and the operator’s and service manuals. The checklist provides space to record temperatures, symptoms, and the evidence behind your next step.Before your next trip, check your RV’s electrical, water, and propane connections, and plan for winterization when freezing weather approaches.The goal: narrow down the problem before you spend money on parts.Takeaways:I advise testing whether the refrigerator cools on propane or electric before ordering any parts.I remind you to ensure the refrigerator has proper twelve-volt power and good fuses before diagnosis.We recommend running the refrigerator at least forty-eight hours before travel to confirm consistent cooling performance.I recommend checking the burner, electrode, and flame on propane models, and promptly cleaning or replacing corroded parts.I advise measuring temperatures in both freezer and refrigerator compartments with thermometers to gather objective evidence.We caution that intermittent faults require careful record-keeping and replication before replacing circuit boards or other expensive components.I emphasize verifying airflow, roof vent clearance, and RV level, as these are shared causes of poor cooling across heat sources.Resources Mentioned in this Episode:Wholesale Warranties - RV Extended WarrantiesResources Mentioned in this Episode - Owner's and Service Manuals.Contact Us - Call, Text, Video, EmailOur Online Resources:The Smart Rver YouTube Channel - Check Out Our No-Nonsense YouTube VideosSunpro Mfg - RV Sunshade, Windshield Covers & Slide Out Awning FabricsHot Boat Ropes - Marine Cordage- Anchor Lines, Dock Lines, Tow Lines, etc.Top Rated Podcast - The Smart RVer Podcast Website

Summary/IntroWhen an RV furnace stops working, the most expensive answer is not always the right one. Before replacing the furnace—or ordering parts based on a guess—you need to understand where its operating sequence has stopped.In this episode, Eric explains how an RV furnace starts and the four things it needs to operate: a call for heat from the thermostat, dependable 12-volt power, an adequate propane supply, and proper airflow. He walks through common furnace problems involving the sail switch, blower motor, ignition system, flame-sensing circuit, ductwork, and control board.You will also learn which problems you can fix with basic maintenance, when a targeted repair makes sense, and when age, corrosion, unavailable parts, repeated failures, or combustion-chamber damage may justify replacement. Eric also covers replacement considerations, including potential fitment and exterior door modifications when installing an aftermarket furnace such as a Fogatti.The goal is to help you diagnose the problem methodically, avoid unnecessary parts replacement, and make a safer, more informed decision about your RV furnace.Show NotesThe Four Things an RV Furnace NeedsAn RV propane furnace requires four basic conditions before it can produce heat:A call for heat from the thermostatStrong, dependable 12-volt DC powerAn adequate supply of propaneProper airflow through the furnace and duct systemThe thermostat is essentially an on-and-off switch. Once it calls for heat, the furnace must complete a specific startup sequence before the burner can operate.Understanding the Furnace Startup SequenceThe blower starts first and must reach sufficient speed. That airflow closes the sail switch, allowing the circuit board to continue the startup sequence.The circuit board then opens the gas valve and activates the ignition system. Once the burner lights, the electrode must verify that a flame is present.Knowing this sequence helps narrow down the problem:No blower may indicate a thermostat, fuse, power, wiring, or ground problem.A blower that runs without ignition may point to low voltage, insufficient airflow, the sail switch, the limit switch, or the circuit board.Clicking without ignition may indicate a propane supply, gas valve, burner, or electrode problem.A flame that lights and quickly shuts down may indicate a flame-sensing, grounding, electrode, or circuit-board issue.Listen carefully to what the furnace does. The point where the normal sequence stops is often the best clue to where the problem is located.Begin With the 12-Volt SystemEven though propane produces the heat, the furnace depends on the RV’s 12-volt electrical system.A weak battery may run the lights but fail to provide enough voltage for the furnace blower, circuit board, gas valve, and ignition system.Check the furnace fuse, battery condition, electrical connections, and grounds. Use a multimeter to test voltage while the furnace attempts to start, because a battery can look acceptable without a load and then drop too low when the blower turns on.Check the Propane SupplyBefore blaming the furnace, confirm that propane is reaching the RV’s appliances.Make sure the cylinders contain propane and the valves are open. Test another propane appliance, such as the stove or water heater, to see whether the problem is isolated to the furnace or affects the entire propane system.Testing propane pressure or working directly with the gas valve and combustion system requires the correct equipment and experience. Never use an open flame to check for a propane leak.Inspect the AirflowRestricted airflow can cause poor heating, sail-switch problems, and high-temperature limit cycling.Inspect the furnace return-air area and make sure it is not blocked by camping gear, storage containers, pet beds, or other items. Check the heat registers and ductwork for closed vents, sharp bends, crushed sections, tears, or disconnected ducts.A furnace cannot operate properly if it cannot move enough air.Perform Basic Furnace MaintenanceSimple preventive maintenance may help reduce furnace failures:Vacuum dust and debris from accessible return-air openings.Inspect the exterior intake and exhaust vents.Look for insect nests, spider webs, leaves, soot, and corrosion.Check accessible ductwork and heat registers.Listen for new blower noises or vibration.Inspect visible wiring and connections for damage.Test the smoke, propane, and carbon monoxide alarms.Check each alarm’s expiration date, not just its battery.Don't ignore soot, delayed ignition, unusual combustion noises, or signs of excessive heat. Turn the furnace off and have it inspected.When a Furnace Repair Makes SenseRepair may be the best choice when the furnace is structurally sound, the heat exchanger is in good condition, replacement parts are available, and a technician has properly diagnosed the failed component.Components such as the thermostat, sail switch, limit switch, blower motor, electrode, or circuit board may be replaceable without replacing the complete furnace.The furnace's age matters, but its overall condition matters more.When Replacement May Be the Better ChoiceReplacement should be considered when:The heat exchanger or combustion chamber is damaged.The furnace has severe rust or water damage.Important replacement parts are no longer available.The furnace has required repeated repairs.Repair costs are approaching the cost of replacement.You can no longer trust the furnace when heat is essential.The existing furnace is incorrectly sized or poorly installed.Do not patch or return to service a cracked, burned-through, or severely corroded heat exchanger.Replacement Is Not Always a Direct SwapA replacement furnace must match more than the original opening size.Consider:Furnace dimensionsBTU ratingDucting requirementsPropane-line locationElectrical connectionsThermostat compatibilityExterior vent and access-door configurationRequired clearancesMounting arrangementEric also shares his practical evaluation of Fogatti replacement furnaces. Although they may offer an alternative for certain applications, fitment and exterior door-kit differences could require permanent RV modifications. Carefully verify the installation requirements before cutting or altering the coach.Maintain, Repair, or Replace?Maintain the furnace when it is fundamentally sound but needs cleaning, improved airflow, duct repairs, connection checks, or other preventive attention.Repair it when a specific failed component has been diagnosed, parts are available, and the rest of the furnace remains safe and dependable.Replace it when structural damage, serious corrosion, obsolete parts, repeated failures, or questionable reliability make continued repairs impractical or unsafe.Diagnose the entire system before replacing the furnace—but never allow the desire to save an older unit to override a genuine propane, combustion, or carbon-monoxide safety concern.Takeaways:I explain that a furnace needs four essentials: a thermostat call, 12-volt power, a propane supply, and proper combustion and interior airflow to operate reliably.We recommend regularly inspecting and cleaning the return air grille and flexible ducting to prevent airflow restrictions and operational failures.I describe diagnostic sequences: blower motor start, sail switch engagement, igniter sparking, and flame sensor feedback; failures at any stage indicate specific component faults.We emphasize checking twelve-volt system health with a multimeter because weak batteries may power lights but not the furnace.I advise replacing a furnace when the combustion chamber is compromised, when parts are unobtainable, or when cumulative repair costs exceed replacement value.We critique Fogatti furnaces for potential fitment issues and inadequate door kits that may require enlarging the RV sidewall and permanent modification.I urge familiarization with tools, especially a multimeter, breaker bars, and ratchets, to enable effective roadside troubleshooting and confident repairs.Resources Mentioned in this Episode:Wholesale Warranties - RV Extended WarrantiesRV Furnace Start Up CycleRV Furnace Won't Start Flow ChartContact Us - Call, Text, Video, EmailOur Online Resources:The Smart Rver YouTube Channel - Check Out Our No-Nonsense YouTube VideosSunpro Mfg - RV Sunshade, Windshield Covers & Slide Out Awning FabricsHot Boat Ropes -
