GE Microwave Error Code F6: Internal Temperature Probe... | appliancefaults.com

Technical Background:

The microwave's main control unit (MCU) monitors the internal temperature probe for accurate temperature readings. The F6 error indicates that the MCU is not receiving a valid signal from the probe, suggesting a problem in the probe circuit. Voltage paths from the probe to the MCU are critical for proper operation.

Symptoms:

The microwave displays error code F6 and will not operate. Food may not cook properly, or the microwave may shut down prematurely.

Possible Causes:

Faulty internal temperature probe
Loose or corroded temperature probe receptacle connections
Damaged wiring harness between the probe receptacle and the control board
Defective main control board (MCU)
Open circuit in the temperature sensor itself
Intermittent short circuit in the receptacle

Solution:

1

Disconnect the microwave from the power outlet.
2

Locate and access the temperature probe receptacle, usually inside the microwave cavity on a side wall. This may require removing the outer cabinet (using a 1/4-inch nut driver).
3

Inspect the receptacle for any signs of damage, corrosion, or loose connections. Clean corroded contacts with electrical contact cleaner.
4

Use a multimeter to test the temperature probe for proper resistance. A typical reading should be between 1k to 10k ohms at room temperature.
5

Test the wiring harness between the receptacle and the main control board for continuity using a multimeter. Repair or replace any damaged wires. Check for 5V DC at the connector on the control board with the unit plugged in (be careful!).
6

If the wiring and probe test good, replace the temperature probe receptacle.
7

If the issue persists, the main control board may be defective and require replacement or licensed technician repair.

Safety Warning:

Always disconnect the microwave from the power outlet before performing any repairs. Microwaves contain high-voltage components that can cause serious injury or death. Lock Out/Tag Out (LOTO) procedures should be followed. Use extreme caution.

Prevention:

Regularly clean the microwave interior to prevent food debris from accumulating around the temperature probe receptacle. Avoid using excessive force when inserting or removing the temperature probe.

Expert Tip:

Some GE microwaves have a service mode. Consult the service manual or online resources to determine the procedure for your specific model. This can allow you to run diagnostic tests and reset error codes.

Frequently Asked Questions

•What is the acceptable resistance range for a GE microwave temperature probe at room temperature?

The acceptable resistance range for a GE microwave temperature probe at room temperature is typically between 1k and 10k ohms. However, consult the service manual for your specific model for the most accurate information.

•How do I safely discharge the capacitor in a GE microwave before working on the internal components?

Discharging the capacitor in a microwave is extremely dangerous and should only be performed by qualified technicians. It involves using a high-voltage probe and resistor to safely bleed off the stored charge. If you are not experienced with this procedure, DO NOT attempt it.

•Where can I find a reliable replacement temperature probe receptacle for my GE microwave?

You can find replacement temperature probe receptacles at appliance parts retailers, both online and in local stores. Be sure to order the correct part number for your specific GE microwave model.
