GE Microwave Error Code F1: Meaning and Fix

On a microwave the code replaces the clock on the display. Unplug the unit for a minute to see if it clears, and note the code before you do. GE writes letters and numbers together with no space, so E22 is one code, not E2 and 2.

GE Appliances, now owned by Haier, mixes legacy GE boards with newer connected platforms. Washers and dryers tend to use E or D codes, ranges and microwaves use F codes, and refrigerators show Er codes. The codes apply to model numbers such as GDF630PSMSS, GDT665SSNSS and GTD65EBSJ0WS; check the label on your unit to confirm yours.

What does the F1 code mean on a GE microwave?

The thermistor that reads the oven cavity temperature is open.

Can I fix the F1 code myself?

Start with the free checks (power reset, connectors, obvious blockages). The likely repair involves the magnetron and live-circuit testing, so if the code returns, a qualified technician is the safer call.

How do I clear the F1 code?

Unplug the microwave for five minutes, plug it back in and press Clear. If F1 comes back, the underlying fault is still there; start with this: failed thermistor.

Part numbers are OEM references; confirm fit by your model number before ordering. Meanings compiled from manufacturer and parts-retailer documentation; see sources below. Unplug the appliance before opening it.

Applies to models including JVM3160RFSS, PVM9179SKSS, JES1460DSWW.
