Whirlpool Induction Range Buzzing During Self-Clean:... | appliancefaults.com

Technical Background:

During the self-clean cycle, the MCU (Microcontroller Unit) activates various components including heating elements, cooling fans, and relays. The MCU sends signals to these components via voltage paths, and any disruption in these paths can lead to abnormal operation and noises. The cooling fan is critical to preventing overheating of the control electronics.

Symptoms:

The homeowner reports a loud buzzing sound emanating from the Whirlpool induction range specifically during the self-clean cycle. The buzzing is unusually loud and concerning. This noise was not present before.

Possible Causes:

Faulty cooling fan motor
Defective relay on the control board
Loose connection in the wiring harness
Induction generator issue
Oven cavity resonance amplified by internal components.

Solution:

1

Disconnect power to the range at the breaker panel.
2

Access the rear panel of the range using a 1/4-inch nut driver.
3

Inspect the cooling fan motor for obstructions or damage. Check the fan motor winding using a multimeter, expecting a reading between 50-150 ohms.
4

Examine the control board for any signs of burnt components or loose connections. Use a non-contact voltage tester to ensure no residual voltage is present.
5

Check the wiring harness for loose connections or frayed wires. Secure any loose connections with wire nuts.
6

Measure the voltage supplied to the cooling fan during a test self-clean cycle (after carefully reassembling and restoring power). Expect 120V AC.
7

If the buzzing persists and all other components test OK, the induction generator may need replacing.

Safety Warning:

Always disconnect power to the range at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed to prevent accidental re-energizing of the circuit. High voltage is present within the range, and improper handling can result in serious injury or death.

Prevention:

Regularly clean the range, including removing any debris from the cooling fan area. Avoid running the self-clean cycle too frequently, as this can put stress on the components. Ensure proper ventilation around the range.

Expert Tip:

Many Whirlpool ranges have a diagnostic mode. To access it, press and hold the CANCEL button for 5 seconds, then press START. This will display any stored error codes and allow you to run component tests, including the cooling fan.

Frequently Asked Questions

•What is the expected lifespan of the cooling fan motor?

The average lifespan of a cooling fan motor in a range is typically 5-7 years, depending on usage and environmental factors such as heat and dust exposure.

•How can I test the relay on the control board?

You can test the relay using a multimeter to check for continuity. When the relay is activated (during the self-clean cycle), there should be continuity between the appropriate terminals. When de-activated, there should be no continuity.

•What is the correct part number for a replacement control board for this model?

The correct part number for the replacement control board can be found on the appliance's model/serial number sticker. Look up the model number on a parts website like AppliancePartsPros.com or RepairClinic.com.
