Whirlpool Induction Range Clicking Like a Clock:... | appliancefaults.com

Technical Background:

Induction ranges use an MCU to control the power to the heating elements. Relays are used to switch the high voltage power to these elements. A rhythmic clicking suggests that a relay is rapidly cycling on and off, or that the MCU is sending erratic signals.

Symptoms:

US homeowner reports a rhythmic clicking sound coming from their Whirlpool induction range, similar to a clock ticking.

Possible Causes:

Defective relay on the control board.
Malfunctioning MCU (Main Control Unit).
Loose wiring connections causing arcing.
Component failure on the power board.
Overheating safety switch cycling.
Interference from other appliances.

Solution:

1

Disconnect power to the range at the breaker panel. Verify 0V AC at the range receptacle using a multimeter.
2

Remove the range's back panel using a 1/4-inch nut driver to access the control board.
3

Visually inspect the control board for any signs of burnt components, bulging capacitors, or damaged relays.
4

Use a multimeter to test the relays for continuity. A normal relay should have continuity across the coil when activated. If the relay coil is open, replace it.
5

Check the wiring connections to the heating elements and the control board. Tighten any loose connections.
6

Reassemble the range and restore power to the breaker. Monitor the range for the clicking sound. If the clicking persists, the MCU may be faulty and require replacement.
7

If the clicking has stopped, monitor for a few days to ensure that the problem has been fully resolved.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any diagnostic or repair work. High voltage is present inside the range, which can cause serious injury or death. Use proper Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Regularly clean the range top to prevent food spills from entering the internal components. Avoid overloading the cooking elements, as this can cause overheating and premature component failure. Ensure proper ventilation around the range to prevent overheating.

Expert Tip:

On some Whirlpool models, you can access a diagnostic mode by pressing and holding the 'Start' and 'Cancel' buttons simultaneously for 5 seconds. This may reveal error codes related to the clicking issue. Note down any error codes before beginning repair.

Frequently Asked Questions

•What voltage should I expect to see at the heating element terminals when the range is operating normally?

You should see approximately 240V AC at the heating element terminals when the element is energized.

•How do I identify the correct relay on the control board that controls the specific heating element?

Trace the wiring from the heating element back to the control board. The relay connected to those wires is the one controlling that element. The service manual is the best source to identify the specific relay.

•If the MCU is faulty, can I replace it myself, or is professional service required?

Replacing the MCU often requires specialized programming and knowledge of the appliance's control system. It's generally recommended to have a qualified technician replace the MCU.
