GE Microwave Error Code F6: Cleaning the Probe Port -... | appliancefaults.com

Technical Background:

The microwave's main control unit (MCU) monitors the temperature probe's resistance to determine the food's internal temperature. The probe sends a low-voltage signal back to the MCU, which interprets this signal and adjusts the microwave's power output. Food residue or a faulty probe disrupts this signal, triggering the F6 error.

Symptoms:

The GE microwave displays an F6 error code on the control panel. The microwave may stop heating or display inaccurate temperature readings when using the temperature probe.

Possible Causes:

Food residue accumulation in the temperature probe receptacle.
Damaged temperature probe.
Faulty temperature sensor within the microwave's control board.
Loose or corroded wiring connections to the probe receptacle.
Defective main control board (MCU).

Solution:

1

Unplug the microwave from the 120V AC outlet. Ensure the breaker is off for extra safety.
2

Locate the temperature probe receptacle inside the microwave cavity, typically on a side wall.
3

Use a small brush or cotton swab dampened with isopropyl alcohol to carefully clean the receptacle. Remove any visible food particles or residue.
4

Inspect the temperature probe for any signs of damage, such as cracks, bends, or exposed wiring. Replace the probe if necessary.
5

Check the wiring connections to the probe receptacle. Ensure they are secure and free from corrosion. Clean corroded terminals with a wire brush.
6

Use a multimeter to test the temperature probe's resistance. Refer to the GE service manual for the correct resistance value at room temperature (approximately 75°F). If the resistance is outside the specified range, replace the probe.
7

Plug in the microwave and test the probe function with a glass of water. If the F6 error persists, the main control board may be faulty and require licensed technician repair or replacement.

Safety Warning:

Disconnect power before performing any repairs. Microwaves contain high-voltage components that can cause serious injury or death. Lock Out/Tag Out (LOTO) procedures must be followed. If you are not comfortable working with electrical appliances, contact a qualified technician.

Prevention:

Regularly clean the temperature probe receptacle with a damp cloth to prevent food residue buildup. Avoid using abrasive cleaners that could damage the receptacle.

Expert Tip:

Some GE microwaves have a service mode that allows you to test the temperature probe's functionality. Consult the service manual for your specific model to access and utilize this feature. This can help pinpoint if the control board is the source of the issue, or even if the probe port pins are corroded and not making proper contact.

Frequently Asked Questions

•What is the typical resistance range I should expect from a GE microwave temperature probe at room temperature (70-75°F)?

The exact resistance value varies depending on the specific GE microwave model. However, a typical range is between 10k ohms and 20k ohms. Consult the service manual for your microwave's model number for the precise value.

•If cleaning the probe port and replacing the probe doesn't fix the F6 error, what are the next most likely components to investigate?

If the probe and port are good, examine the wiring harness connecting the probe receptacle to the main control board for continuity and shorts. A damaged wire can cause the F6 error. If wiring is good, then the main control board is likely the issue.

•Can a surge protector help prevent F6 errors caused by power fluctuations?

While a surge protector can protect the microwave from damage caused by power surges, it is unlikely to prevent F6 errors caused by issues with the temperature probe or its circuitry. A surge protector primarily safeguards against voltage spikes, not the subtle malfunctions that trigger the F6 error.
