GE Profile Combo Dryer: Troubleshooting Long Drying... | appliancefaults.com

Technical Background:

The GE Profile Combo dryer uses a Main Control Unit (MCU) to manage the drying cycle. The MCU monitors moisture levels via the moisture sensor, regulates heating element operation via relays, and controls the blower motor. The MCU logic relies on accurate sensor data and proper voltage paths to ensure efficient drying. The heating element typically operates on 240V AC, while the control circuits use 120V AC and low-voltage DC.

Symptoms:

The GE Profile Combo dryer takes an excessively long time to dry small loads, often requiring multiple cycles. Clothes may still be damp after a full cycle, even with optimal settings.

Possible Causes:

Clogged lint filter or exhaust duct.
Faulty moisture sensor.
Defective heating element or thermostat.
Restricted airflow due to a kinked or blocked vent hose.
Incorrect dryer settings selected.

Solution:

1

Unplug the unit or turn off the breaker in the breaker panel.
2

Inspect and clean the lint filter thoroughly. Ensure it is free of debris.
3

Disconnect the vent hose from the back of the unit and the wall. Check for any obstructions. Clean the vent hose and duct using a vent brush.
4

Locate the moisture sensor inside the dryer drum. Clean the sensor bars with a damp cloth. Check the sensor wiring for damage.
5

Using a multimeter, test the heating element for continuity. A reading of 10-30 ohms is typical. If open, replace the heating element.
6

Check the thermostat with a multimeter for continuity. It should have continuity at room temperature. Replace if open.
7

Reassemble the dryer and test a small load with the appropriate settings.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Use proper Lock Out Tag Out (LOTO) procedures to prevent accidental energizing of the circuit. The dryer operates on 240V AC – high voltage can cause serious injury or death.

Prevention:

Clean the lint filter after every load. Inspect and clean the exhaust duct at least once a year. Avoid overloading the dryer. Use appropriate dryer settings for the type of load.

Expert Tip:

To access the GE dryer's service mode, simultaneously press and hold the Start/Pause and Signal buttons for 3 seconds. This will allow you to run diagnostic tests and view error codes.

Frequently Asked Questions

•What is the proper ohm reading for the heating element on this model?

The heating element should typically read between 10 and 30 ohms. An open circuit indicates a faulty element that needs replacement.

•Where is the moisture sensor located in the dryer drum?

The moisture sensor is typically located on the front bulkhead inside the dryer drum. It usually consists of two metal bars.

•How do I check the vent for blockages inside the wall?

Use a dryer vent cleaning kit with a flexible brush attachment to clear any lint buildup. Alternatively, you can hire a professional duct cleaning service.
