Hotpoint Dryer Clicking Sound When Starting:... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) sends a 120V AC signal to the motor start relay when the start button is pressed. This relay then energizes the motor. The door switch must be closed to complete the circuit. If any component in this chain fails, the motor will not start, and a clicking sound from the relay attempting to engage is common.

Symptoms:

The US homeowner reports a clicking sound when attempting to start their Hotpoint dryer. The drum does not turn, and the unit fails to power on fully. The clicking noise repeats every few seconds.

Possible Causes:

Defective start relay.
Faulty motor.
Failed door switch.
Blocked blower wheel.
Broken drive belt.
Burned out thermal fuse.

Solution:

1

Unplug the dryer from the outlet. Always Lock Out Tag Out (LOTO) before working.
2

Remove the rear access panel using a 1/4-inch nut driver.
3

Visually inspect the drive belt for breaks or damage. Replace if needed.
4

Check the thermal fuse for continuity using a multimeter. It should read near 0 ohms. Replace if open (infinite resistance).
5

Access the motor. Use a multimeter to test for voltage at the motor when the start button is pressed. Should read 120V AC.
6

If voltage is present but the motor doesn't run, the motor is likely defective. Replace the motor.
7

Verify the door switch functionality. A faulty door switch can prevent the dryer from starting. Test for continuity when the door is closed. Replace if needed.

Safety Warning:

Disconnect power to the dryer at the breaker panel before attempting any repairs. Capacitors inside the dryer can hold a dangerous electrical charge even after the unit is unplugged. Use extreme caution. Always Lock Out Tag Out (LOTO) the breaker.

Prevention:

Regularly clean the lint trap after each use. Annually inspect and clean the dryer vent duct to ensure proper airflow. Check the drive belt and replace it every 2-3 years.

Expert Tip:

Some Hotpoint dryers have a service mode. Press and hold the 'Start' and 'End of Cycle' buttons simultaneously for 3 seconds to access diagnostic codes. This can help pinpoint the faulty component.

Frequently Asked Questions

•How do I test the motor start relay?

The motor start relay can be tested for continuity using a multimeter. Disconnect the relay and check for resistance across its terminals. Compare the reading to the manufacturer's specifications. A reading outside the specified range indicates a faulty relay.

•Where is the thermal fuse located?

The thermal fuse is typically located on the blower housing or near the heating element. It is a small, white, rectangular component with two wires attached. Refer to your dryer's wiring diagram for the exact location.

•What is the proper way to clean the dryer vent duct?

Disconnect the duct from the dryer and the wall. Use a dryer vent cleaning brush kit to remove lint buildup inside the duct. You can also use a vacuum cleaner with an extension hose to remove loose lint. Ensure the duct is reconnected securely to prevent leaks.
