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

Technical Background:

The Main Control Unit (MCU) controls the drying cycle based on signals from moisture sensors, temperature sensors, and timers. Voltage is supplied to the heating element via relays controlled by the MCU. If sensor values are out of range or voltage is insufficient, the drying time will be extended.

Symptoms:

The GE Profile Combo unit is taking an excessively long time to dry clothes, much longer than usual.

Possible Causes:

Incorrect drain hose height
Clogged or restricted vent duct
Faulty moisture sensor
Defective heating element
Blocked lint filter

Solution:

1

Verify drain hose height: Ensure the drain hose is installed at the correct height as specified in the system manual, typically between 30 and 96 inches above the floor.
2

Inspect vent duct: Disconnect the vent duct from the unit and visually inspect for clogs or restrictions. Use a vent brush to thoroughly clean the duct.
3

Test moisture sensor: Locate the moisture sensor inside the drum. Use a multimeter to check for continuity. A reading outside the specified range indicates a faulty sensor; replace if needed.
4

Check heating element: Using a multimeter, test the heating element for continuity. If there's no continuity, the element is likely burned out and needs replacement. Ensure the unit is disconnected from power before testing.
5

Clean lint filter: Remove and thoroughly clean the lint filter. A clogged filter restricts airflow, leading to longer drying times.
6

Check voltage at heating element: During a drying cycle, use a multimeter to check the voltage at the heating element terminals. You should read approximately 240V AC. If the voltage is significantly lower or absent, there might be an issue with the power supply or control board.
7

Inspect and clean the condenser unit: If applicable, access the condenser unit (follow manufacturer's instructions) and check for lint buildup. Clean thoroughly with a brush and vacuum.

Safety Warning:

Always disconnect the power supply to the unit at the breaker panel before performing any repairs. Use appropriate Lock-Out/Tag-Out (LOTO) procedures. High voltage components are present inside the unit.

Prevention:

Regularly clean the lint filter after each load. Inspect and clean the vent duct at least every six months. Ensure the drain hose is properly installed and free from kinks. Periodically check the condenser unit (if applicable) for lint buildup.

Expert Tip:

To enter service mode, press and hold the Start/Pause button and the Wrinkle Care button simultaneously for approximately 3 seconds. This may allow access to error codes and diagnostic tests to pinpoint the issue.

Frequently Asked Questions

•What is the correct drain hose height for my GE Profile Combo model?

Refer to the installation manual specific to your model number. The height is typically between 30 and 96 inches, but confirming with your manual is essential.

•How do I test the moisture sensor with a multimeter?

First, disconnect the power. Locate the moisture sensor inside the dryer drum. Set your multimeter to the ohms setting. Place the probes on the sensor terminals. Check the reading against the service manual specifications. An open circuit (infinite resistance) or a very low resistance often indicates a faulty sensor.

•Where is the heating element located in my GE Profile Combo?

The heating element is typically located at the rear of the dryer drum, inside a metal housing. Access usually requires removing the back panel of the unit. Always disconnect power before attempting to access the heating element.
