Question about Kenmore 63792 Microwave Oven
The F9 error code indicates a failed inverter. If resetting the unit does not help you will need to have the inverter & harness checked.
This can sometimes by caused by a power surge or glitch through the electrical lines.
You can sometimes clear this fault by completely unplugging the microwave for 1 minute.
Plug it back in and see if the fault code returns.
If it does, then you have an internal component failure that will need to be serviced by a technician.
Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances.
Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged.
A microwave radiation leakage test must be performed on the unit following any internal component repair.
It does not ALWAYS indicate a inverter control board problem however in other brands/models.
LG's service manual (for an example) suggests the f-9 code could be due to line voltage, magnetron, inverter module, "Relay2", or a loose connection between door/magnetron/control pcb.
Other indications might help narrow down these choices before having to pull out your multimeter and crack open the microwave case.
For example, if the microwave works, but heats slowly, then the troubleshooting manual narrows your choices down to magnetron or line voltage problems, and pretty much rules out the other possibilities.
