Thetford N3000 user manual

Error code 3 on the Thetford N3000 refrigerator typically indicates an issue with the temperature sensor. The error means that the refrigerator has detected a fault or an open circuit in the sensor. This could be caused by a loose connection, a faulty sensor, or a problem with the circuit board. It is recommended to check the wiring and connections to ensure they are secure and in good condition. If the issue persists, it may be necessary to contact a professional technician for further diagnostic and repair.

The blue light flashing on your Thetford N3000 fridge could indicate a few things:
1. Error in Connection: If the blue light is flashing continuously, it might be indicating a problem with the power supply. Make sure the fridge is properly connected.
2. Temperature Fluctuations: Sometimes, the flashing blue light can indicate temperature fluctuations inside the refrigerator. It might be too high for the settings you have selected.
3. Thetford AES system: The blue light flashing can also be related to Thetford Automatic Energy Selector (AES) system, which automatically selects the best energy source available (230V, 12V, gas). The light may flash if the system fails to switch over to the next source in line when the power from the current source is insufficient or when switching power sources.
4. Fault Message: Some models of the Thetford N3000 series fridge display a specific flashing sequence which represents different fault messages. Your manual should provide more information about this.
In the end, if the fridge is not working right or if the blue light is continuously flashing, it is best to contact an authorized Thetford service centre or dealer for help.

Error code 2 on the Thetford N3000 refers to a faulty AC heater. If you see this error code, it means that there is an issue with the AC heating element of the refrigerator. It could be caused by a wiring problem, a faulty heating element, or a malfunctioning control board. You may need to consult the refrigerator's manual or contact Thetford customer support for further assistance in troubleshooting or resolving the issue.

There could be several reasons why your Thetford N3000 fridge is not working on gas. Here are a few possible causes:
1. Gas supply issue: Ensure that there is enough gas in the propane tank and that the gas supply is turned on. Check the gas valve and regulator for any obstructions or damage.
2. Ignition problem: The fridge may fail to ignite if there is an issue with the ignition system. Make sure that the gas igniter is sparking properly and that the burner assembly is clean and free of debris.
3. Gas valve problem: If the gas valve is faulty or clogged, it may prevent the flow of gas to the burner. Check the valve for any damage or blockage and consider having it serviced or replaced if necessary.
4. Thermocouple issue: The thermocouple is a safety device that detects the presence of a flame. If it is not functioning correctly, it may prevent the gas flow even if the igniter is working. Test the thermocouple to ensure it is generating the required voltage.
5. Control board malfunction: The control board in the fridge may be experiencing a malfunction, preventing the gas operation. Try resetting the control board or consult a professional technician to diagnose the issue.
If you have tried these troubleshooting steps and your Thetford N3000 fridge still does not work on gas, it is recommended to contact a qualified RV technician or Thetford customer support for further assistance.
