Whirlpool Microwave Error Code F4-E0

F4-E0 indicates that the microwave's control board has detected a short in the meat probe circuit. The meat probe is a thermistor-based temperature sensor that plugs into a port inside the oven cavity. The board expects to see a specific resistance range from the probe, and when the reading drops to near zero, it flags this fault. The most likely cause is a shorted or damaged probe.

You should not ignore an active fault code, but if the probe is simply disconnected and stored, the microwave may resume normal operation without the probe-based cooking function. However, continued use with a shorted probe connected could affect control board performance. Disconnect the probe, confirm the fault clears, and do not use probe-assisted cooking until the issue is resolved.

If the meat probe itself is shorted, replacement probes typically range from $15 to $50 depending on the specific model. If the probe port wiring or control board requires repair or replacement, professional service costs can range from $100 to $300 or more depending on parts and labor rates in your area.

Yes, in many cases. Start by unplugging the microwave and removing the meat probe, then use a multimeter to check the probe's resistance. A working probe should read approximately 78 kilohms at 60°F or 37 kilohms at 90°F. If the probe reads near zero ohms, replacing the probe is a straightforward repair that does not require disassembling the microwave.

Unplugging the microwave may temporarily clear the displayed code, but the fault will return if the shorted probe remains connected when power is restored. The underlying cause must be corrected, by replacing the probe or repairing the port or wiring, before the error will stay cleared permanently.
