Microwave - Error, Fault or Function Codes
Fault codes are programmed in all microwave oven controls. These codes help our technicians quickly diagnose issues with the microwave oven. In the event that the electronic control displays an error, fault or function code, a trained Service Technician should be called to diagnose and correct the issue.
A summary of the most common fault codes and their meanings are listed below:
|F1||Open Thermal Sensor, due to excessive heat in microwave cavity|
|F2||Shorted thermal sensor|
|F3||Shorted touch pad panel|
|F4||Open humidity sensor|
|F5||Shorted humidity sensor|
|F6||Shorted temperature probe|
|F10||Shorted touch screen|
Open temperature probe or the probe is not plugged in during a temp cook function. Make sure probe is firmly inserted into the wall of microwave and the food item.
|888, 8888 or PF||It is possible to see this display upon initial installation or after power was restored due to a power failure. This display can be canceled and normal operation resumed by touching the Cancel/Off or Clear/Off pad. The clock can then be reset on models so equipped.|
|18 power watch code||Indication of an issue with the electronic control in the microwave.|
Sometimes shutting off the circuit breaker or fuse that supplies power to the microwave oven for 30 seconds will clear the fault, error or function code. However, there are some cases when service may be required.
