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.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
Guide to RV battery disconnect switches. Covers when to use, what loses power, and best practices for storage and daily use.
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 HWH 325 levelers turn off immediately after pressing extend buttons, it's typically caused by low voltage under load, loose connections, or a faulty control module. Check battery voltage under load and inspect all connections first.
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.
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.
Consistent 2-minute shutdown under load indicates fuel delivery cannot keep up with demand. Check fuel pump, bleed system, verify no restrictions. Also check if generator is undersized for AC load - may need soft start on AC unit.
Your MaxxAir/Fantastic fan is likely experiencing a moisture sensor malfunction or rain sensor false trigger. The fix typically involves checking sensor connections, cleaning contacts, or adjusting sensitivity settings.
Your Coleman 9420-381 thermostat has failing solid-state switching components causing voltage drop during heating calls. This is a known issue with this model - replace it with a more reliable thermostat or return to a mechanical relay-based unit.
P068A indicates an ECM/PCM Power Relay Control Circuit malfunction in your Ford V10. This typically involves a faulty power relay, damaged wiring, or ECM issues causing engine stalling and starting problems.
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.
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.
After running out of gas, air is in fuel system. Hold start switch longer (15-30 seconds) to purge air. May take several attempts. Check oil level is correct after change.
