Error codeF5
ApplianceMicrowave
Summary
F5 stands for a shorted humidity sensor.
It is listed for all GE microwave ovens.
GE wants a trained service technician to diagnose and correct it.
Why the technician route
Codes like this exist so that a technician can find the cause quickly. For that reason GE does not give an owner-level fix, only the advice to call for a trained technician.
Dial (415) 729-2045 when F5 is on the display of a GE microwave in San Francisco or nearby Bay Area towns. We will ask for the model number. Our microwave repair page gives an overview.
Model compatibility: GE reuses codes across series and model years, so F5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F5 indicates a shorted humidity sensor.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
