GE Profile Combo Dryer: Troubleshooting Overloading... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the moisture sensor voltage to determine dryness. Higher moisture levels result in a lower voltage signal. The MCU also controls the heating element relay. Voltage paths include 120V AC to the heating element and 5V DC to the moisture sensor.

Symptoms:

The homeowner observes that the GE Profile Combo dryer cycle takes significantly longer than usual to dry clothes. Clothes may still be damp after a full cycle, even when using automatic dryness settings. The homeowner suspects that overloading is the cause.

Possible Causes:

Overloaded dryer drum exceeding capacity.
Restricted airflow due to clogged lint filter.
Blocked or kinked exhaust vent.
Faulty moisture sensor.
Defective heating element or thermostat.

Solution:

1

Unplug the GE Profile Combo from the 120V AC outlet.
2

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

Disconnect the vent and inspect for obstructions. Clear any lint buildup.
4

Check the lint filter housing for clogs and remove any debris.
5

Locate the moisture sensor inside the drum (usually near the lint filter). Clean the sensor bars with a slightly damp cloth.
6

Use a multimeter to test the heating element for continuity. A reading of around 9-13 ohms is typical. If no continuity, replace the element.
7

Inspect the thermostat for continuity. It should be closed at room temperature. Replace if open.

Safety Warning:

Disconnect power to the appliance at the breaker panel before performing any repairs. Use proper Lock-Out/Tag-Out (LOTO) procedures. Be aware of high voltage components inside the appliance. Wear appropriate safety glasses.

Prevention:

Avoid overloading the dryer. Clean the lint filter after every load. Inspect and clean the exhaust vent at least once a year to ensure proper airflow. Use dryer sheets sparingly, as they can contribute to lint buildup.

Expert Tip:

To access the service mode on some GE Profile Combo models, press and hold the 'Start' and 'Select' buttons simultaneously for 3 seconds. This will allow you to run diagnostic tests and view error codes.

Frequently Asked Questions

•How do I properly clean the moisture sensor?

Use a slightly damp (not wet) cloth or a melamine sponge (like Mr. Clean Magic Eraser) to gently wipe the sensor bars. Avoid using harsh chemicals or abrasive cleaners, as these can damage the sensor.

•What is the correct way to check the exhaust vent for blockage?

Disconnect the vent from the dryer and the wall. Visually inspect the vent for lint buildup. Use a vent brush or vacuum cleaner to remove any blockages. Ensure the vent is not kinked or crushed.

•How much laundry is considered an 'overload' for my GE Profile Combo?

Refer to the owner's manual for the specific capacity of your model. Generally, avoid filling the drum more than two-thirds full. Clothes should be able to tumble freely for proper drying. If clothes are tightly packed, it's likely overloaded.
