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.
Fix your RV refrigerator with this guide covering Dometic, Norcold, and residential fridge issues.
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.
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.
When your RV propane furnace clicks but won't light, it's usually caused by a dirty or failing igniter, blocked air intake, low propane pressure, or faulty control board. Most issues can be resolved by cleaning the igniter, checking propane supply, and ensuring proper airflow.
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.
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.
Intermittent flame failure varying from seconds to minutes indicates marginal flame sensor signal or airflow issues. Clean flame sensor with steel wool until shiny. Check combustion air intake and exhaust routing. Gas pressure fluctuation also possible.
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.
Everything you need to know about RV plumbing systems from fresh water supply to waste management.
RV fridge losing 12V with ignition on indicates wiring issue in battery isolator or relay system.
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.
Your Suburban SW6D water heater likely has a combustion air intake blockage or ECO switch issue preventing proper airflow. The problem occurs because the unit needs adequate combustion air to maintain the flame safely.
