Fix your RV refrigerator with this guide covering Dometic, Norcold, and residential fridge issues.
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.
When your RV furnace blows cold air but won't ignite, the problem is usually a dirty flame sensor, blocked air intake, faulty ignition board, or gas supply issue. Most ignition problems can be diagnosed and fixed with basic cleaning and component checks.
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.
Furnace that lights for 5-10 seconds then shuts off is classic flame sensor failure. Clean the sensor with steel wool or emery cloth - do not use sandpaper. If cleaning fails, replace the sensor. Located near burner, single wire connection.
AquaHot cycling every 15 minutes at idle is not normal. Possible causes include heat loss through stuck zone valves, thermostat issues, or circulation pump running when it shouldnt. Check that all zone valves are closed and pumps are off when no heat is called for.
Furnace running 10 seconds then stopping is usually sail switch not sensing airflow, dirty flame sensor, or blocked vents. Check blower operation, clean flame sensor, verify air paths clear.
When your Dometic RV fridge ignites perfectly on AUTO but fails when manually switched to gas mode, the issue is typically a faulty ignition control module or loose wiring connections. The control board may be sending conflicting signals between manual and automatic operation modes.
The 'no CO' error on your Norcold N842IM after 8-9 hours on propane is typically caused by combustion issues like a dirty burner, blocked flue, or faulty thermocouple. Start by cleaning the burner assembly and checking for proper ventilation.
Unfortunately, you cannot replace just the tank on a Suburban SW6P water heater - the tank and outer housing are manufactured as one integrated unit. When rust appears during flushing, it's time to replace the entire water heater.
For the Jamboree fridge, check LP gas flow, burner for debris, and 12V power. Ford 460 EFI conversion costs more than the RV is worth - maintain the carburetor instead.
Propane smell behind fridge means a leak - shut off tank immediately. Use soapy water to find bubbles at fittings and lines. Tighten loose fittings or replace deteriorated gas line.
Furnace running 5-10 minutes then quitting usually indicates overheating from restricted airflow, weak flame, or failing control board. Check combustion air intake, propane pressure, and burner flame quality. Control board becomes suspect if other tests pass.
RV fridge losing 12V with ignition on indicates wiring issue in battery isolator or relay system.
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.
