When an RV water heater pilot light won't stay lit after releasing the button, it's usually caused by a faulty thermocouple that needs cleaning or replacement. The thermocouple is a safety device that detects the pilot flame and allows gas to flow.
When a Norcold refrigerator starts on propane but shuts off after 1-2 hours, it's typically due to a failing thermocouple, dirty burner, or control board issue. Most problems can be diagnosed by checking the flame appearance and thermocouple connection.
Lukewarm water from your RV heater is typically caused by a failing heating element, sediment buildup, or thermostat issues. Most problems can be fixed by replacing the heating element, flushing the tank, or adjusting the thermostat.
The Dometic R31 is a solid upgrade from older units like the Wedgewood Vision, with reliable oven performance. The pressure test requires a 0-15 PSI gauge connected to the regulator test port to verify 11" WC gas pressure.
Replacing your power-hungry 3-way absorption fridge with a 12V compressor fridge like the Dometic DMC4101 can reduce power consumption by 70-80%, typically using 60-80 watts instead of 250-300 watts continuously.
Tankless RV water heaters lose significant efficiency at high altitude - about 4% per 1,000 feet. Above 4,500 feet, expect reduced output and possible flame failure. Consider traditional tank heaters if you frequently camp in mountains.
Use a 20lb or 100lb portable propane tank for winter RV storage heating. Connect at quick-connect port or regulator. Set thermostat to 40F to prevent freezing with minimal propane use.
Dometic RM2453 uses DSI direct spark ignition not a standing pilot or 2-stage burner. Burner ignites on demand when thermostat calls for cooling. Single stage operation runs full on or off.
Keep your RV comfortable in any weather with this AC, furnace, and heat pump troubleshooting guide.
True non-swivel propane pigtails are uncommon. Fix leaking swivels by replacing O-rings with Viton or using gas-rated yellow PTFE tape. Quality brass pigtails from Flame King or Camco have better seals. Always leak test connections.
Suburban SDN2U thermocouple position issues are known on 2024-2025 models. Adjust thermocouple tip position to match working burner - should sit in outer flame cone. This is likely warranty repair on new Jayco. Document issue before DIY attempts.
Replace Atwood 8535-III with Dometic 8535-IV direct replacement or Suburban NT-30SP alternative.
Oven pilot works but main burner does not light usually indicates failed safety valve or weak thermocouple. Check for burner tube blockage first. Safety valve is most common failure requiring replacement.
A propane smell from your Atwood 8525 furnace during operation typically indicates improper burner installation, incorrect air-to-gas mixture, or a cracked heat exchanger. Check burner alignment, air intake sealing, and combustion chamber integrity immediately as this is a serious safety concern.
When your Dometic RV refrigerator cools on electric but not propane, the issue is typically a dirty burner, faulty thermocouple, blocked flue, or gas supply problem. Most issues can be resolved with cleaning and basic adjustments.
