Hotpoint Dryer Timer Not Advancing: Symptoms and... | appliancefaults.com

Technical Background:

The timer motor receives intermittent power based on temperature signals from the cycling thermostat. The motor slowly turns the timer cam, which opens and closes contacts to control various dryer functions. The MCU (Microcontroller Unit) on newer models can control timer advancement through electronic signals.

Symptoms:

The dryer runs, but the timer stays in one position and does not advance. Clothes may stay damp even after a long drying cycle.

Possible Causes:

Faulty timer motor
Defective cycling thermostat
Blocked exhaust vent
Stuck or failing operating thermostat
Wiring harness issue
Damaged door switch

Solution:

1

Unplug the dryer from the outlet. Ensure LOTO.
2

Access the control panel. Usually involves removing screws with a 1/4-inch nut driver.
3

Locate the timer. Use a multimeter to test the timer motor for continuity. Should show resistance; if open, replace the timer.
4

Check the cycling thermostat (usually on the blower housing). Test for continuity with a multimeter. It should be closed at room temperature. If open, replace it.
5

Inspect the exhaust vent for obstructions. Clear any lint buildup.
6

Examine the operating thermostat for continuity. It should be closed. If open, replace it. A hair dryer can be used to heat it up and verify operation, watching with the multimeter.
7

Check wiring connections to the timer and thermostats. Look for loose or burned wires.

Safety Warning:

Disconnect power to the dryer before performing any repairs. Use Lock Out Tag Out (LOTO) procedures to prevent accidental energization. High voltage is present when the dryer is plugged in.

Prevention:

Clean the lint filter after every load. Inspect and clean the exhaust vent at least once a year to prevent lint buildup and overheating. Have a licensed technician inspect the dryer annually.

Expert Tip:

Some Hotpoint dryers have a diagnostic mode. Press and hold the Start/Pause button and another specific button (refer to the service manual) for 5 seconds to enter the diagnostic mode. This can display error codes related to timer or thermostat faults.

Frequently Asked Questions

•How do I access the dryer's control panel?

Typically, you'll need to unplug the dryer, then locate screws on the back or top of the control panel. Removing these screws will allow you to lift or slide the panel for access. Refer to the dryer's service manual for specific instructions.

•What should the resistance reading be on a functioning timer motor?

A functioning timer motor usually has a resistance reading between 2,000 and 3,000 ohms. However, this can vary by model, so it's best to consult the service manual for your specific Hotpoint dryer.

•Where is the cycling thermostat located in a Hotpoint dryer?

The cycling thermostat is usually located on the blower housing, inside the dryer cabinet. You'll likely need to remove an access panel to reach it. The exhaust vent is attached to the blower housing.
