GE Profile Combo Dryer Taking Too Long: Evaporator Fan... | appliancefaults.com

Technical Background:

The GE Profile Combo's drying system relies on a heating element, evaporator fan, and thermistor, all controlled by the main control unit (MCU). The MCU monitors temperature via the thermistor and activates the heating element and evaporator fan accordingly. The evaporator fan motor moves air across the heating element and through the clothes drum. A restricted airflow or a malfunctioning heating element will increase drying time.

Symptoms:

The homeowner observes that the GE Profile Combo dryer cycle is taking significantly longer than usual to dry clothes. Clothes may still be damp after a full cycle. There may not be any error codes displayed.

Possible Causes:

Blocked lint filter or venting
Faulty evaporator fan motor
Defective heating element
Thermistor malfunction
Control board issue
Clogged condenser coil (if applicable)

Solution:

1

Unplug the GE Profile Combo from the power outlet.
2

Inspect and thoroughly clean the lint filter and venting system. Ensure there are no kinks or obstructions in the vent hose.
3

Locate the evaporator fan motor (usually near the condenser coils). Check for any obstructions preventing it from spinning freely. Use a multimeter to test the motor windings for continuity. A reading of OL (open line) indicates a failed motor.
4

Test the heating element for continuity using a multimeter. A reading of OL (open line) means the element is burned out and needs replacement.
5

Check the thermistor with a multimeter. Refer to the service manual for the correct resistance value at room temperature (around 75°F). An incorrect reading indicates a faulty thermistor.
6

Inspect the control board for any visible signs of damage, such as burned components or swollen capacitors. If damage is evident, consider replacing the control board.
7

If the condenser coil is accessible, clean it with a soft brush and vacuum to remove lint buildup.

Safety Warning:

Always disconnect the appliance from the power supply before performing any repairs. Capacitors can hold a dangerous electrical charge even after the unit is unplugged. Use caution when working around electrical components. Lock Out / Tag Out (LOTO) procedures must be followed.

Prevention:

Clean the lint filter after every drying cycle. Inspect and clean the venting system at least every six months to prevent lint buildup. Avoid overloading the dryer, as this can restrict airflow.

Expert Tip:

Many GE dryers have a diagnostic mode. Consult the service manual for your specific model to enter the diagnostic mode and retrieve error codes. This can often pinpoint the problem more accurately. The exact steps involve a specific sequence of button presses. Check the service manual.

Frequently Asked Questions

•What is the typical resistance value of the thermistor at room temperature (75°F)?

Refer to the specific service manual for your GE Profile Combo model. However, a typical range for a thermistor at 75°F is between 10,000 and 50,000 ohms.

•How do I access the evaporator fan motor on my GE Profile Combo?

Accessing the evaporator fan motor usually involves removing the rear panel of the dryer. Consult the service manual for detailed instructions and diagrams specific to your model to avoid damaging any components.

•Where can I find the service manual for my specific GE Profile Combo model?

You can often find the service manual online by searching for the model number followed by "service manual" (e.g., "GE Profile Combo model XYZ service manual"). GE's website or third-party appliance repair websites are good resources.
