GE Profile Advantium Turntable Not Spinning:... | appliancefaults.com

Technical Background:

The Microwave Control Unit (MCU) manages various functions, including the turntable motor. The MCU sends a 120V AC signal to the turntable motor when the start button is pressed and the door switches confirm proper closure. A fault in the MCU, wiring, door switch or the motor itself can prevent the turntable from spinning.

Symptoms:

The homeowner reports that the GE Profile Advantium microwave is heating food properly, but the turntable is not rotating.

Possible Causes:

Turntable motor failure
Turntable motor control board malfunction
Faulty door switch (interlock)
Damaged turntable drive coupler
Wiring harness issue between the control board and the motor
Defective high voltage diode. This may not be the root cause but can sometimes indirectly affect low voltage circuits.

Solution:

1

Unplug the Advantium from the outlet to disconnect power. Adhere to LOTO procedures.
2

Remove the outer case. Typically, this involves removing screws on the back panel using a 1/4-inch nut driver.
3

Locate the turntable motor, typically at the bottom of the microwave cavity.
4

Use a multimeter to check for 120V AC at the motor terminals when the microwave is running (with a cup of water for testing). Be extremely careful of high voltage.
5

If no voltage is present, trace the wiring back to the control board. Inspect the wiring harness for breaks or loose connections.
6

If voltage IS present at the motor, the motor is likely faulty. Replace the motor. A new motor can typically be installed with a Phillips head screwdriver.
7

If no voltage at the motor and wiring is good, consider replacing the motor control board.

Safety Warning:

Always disconnect power to the microwave 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.

Prevention:

• Avoid slamming the microwave door, as this can damage the door switches.
• Regularly clean the inside of the microwave to prevent food debris from interfering with the turntable mechanism.

Expert Tip:

Some Advantium models have a service mode accessible through a specific button sequence. This mode allows for diagnostic testing of individual components, including the turntable motor. Consult the service manual for the exact sequence for your model.

Frequently Asked Questions

•How do I access the service mode on my GE Profile Advantium?

The service mode sequence varies by model. You'll need to consult the specific service manual for your Advantium's model number. Search online for "GE Advantium [Your Model Number] service manual".

•What voltage should I expect to see at the door switch terminals?

The door switch typically operates on 120V AC. When the door is closed, the switch should allow voltage to pass through. When open, the circuit should be interrupted. Use a multimeter to verify.

•Where can I purchase replacement parts for my GE Advantium?

You can purchase replacement parts from authorized GE parts distributors, appliance parts retailers, or online marketplaces. Be sure to have your model number handy when ordering parts to ensure compatibility.
