If your Norcold RV refrigerator has stopped working or is not cooling properly, don’t panic! Many common issues can be resolved with a few simple troubleshooting steps and repairs. In this comprehensive guide, we will explore the most prevalent problems with Norcold RV refrigerators and provide detailed instructions on how to fix them yourself.
Understanding the Norcold RV Refrigerator
Norcold RV refrigerators are absorption refrigerators that use ammonia and hydrogen as refrigerants. They are designed to operate on either propane or 120-volt electricity and are commonly found in RVs and campers. Here are some key components of a Norcold RV refrigerator:
- Cooling unit: The cooling unit is the heart of the refrigerator and consists of an evaporator, condenser, and absorber.
- Burner: The burner heats the ammonia in the cooling unit to create a cooling effect.
- Thermostat: The thermostat controls the temperature inside the refrigerator.
- Control board: The control board manages the operation of the refrigerator, including the burner and thermostat.
Common Problems and Troubleshooting
1. No Cooling
Possible causes:
- Faulty cooling unit
- Clogged burner
- Malfunctioning thermostat
Troubleshooting steps:
1. Check if the refrigerator is plugged into a power source and that the breaker is not tripped.
2. Ensure that the propane tank is full and that the gas line is not obstructed.
3. Light the burner and listen for a clicking sound. If you don’t hear a click, the igniter may be faulty.
4. Check the thermostat to ensure it is set to a proper temperature.
2. Insufficient Cooling
Possible causes:
- Dirty condenser coils
- Blocked air vents
- Overcrowded refrigerator
Troubleshooting steps:
1. Clean the condenser coils located on the back or bottom of the refrigerator using a vacuum cleaner or brush.

2. Check if the water pump is running by listening for a humming sound. If it is not running, it may need to be replaced.
3. Inspect the water tank for any cracks or leaks.
4. Unusual Noises
Possible causes:
- Rattling compressor
- Loose fan
- Worn bearings
Troubleshooting steps:
1. Check if the compressor is making a rattling sound. This could indicate loose mounting bolts.
2. Inspect the fan for any obstructions or loose blades.
3. If you hear a grinding noise, it may be caused by worn bearings.
5. Error Codes
Possible causes:
- Faulty control board
- Sensor malfunction
Troubleshooting steps:
1. Refer to the manufacturer’s manual to identify the specific error code.
2. Check the wiring connections to the control board.
3. Reset the control board by unplugging the refrigerator and plugging it back in.
Advanced Repairs
1. Replacing the Cooling Unit
If the cooling unit is faulty, it must be replaced. This is a complex repair that should be performed by a qualified technician.
2. Fixing a Clogged Burner
To unclog a burner, remove the burner assembly and use a wire brush to clean the orifice. Ensure that there is no debris or carbon buildup blocking the gas flow.
3. Troubleshooting the Control Board
If the control board is malfunctioning, it may need to be replaced. Before replacing the control board, check the wiring connections and ensure that the power supply is stable.
