GE UltraFresh Vent System Condensation on Laundry Wall:... | appliancefaults.com

Technical Background:

The GE UltraFresh Vent System is designed to remove excess moisture from the washer drum after each cycle, preventing mold and mildew growth. The MCU (Main Control Unit) controls the vent fan motor based on moisture sensor readings and cycle parameters. Voltage is supplied to the vent fan motor via a relay controlled by the MCU. Issues with the motor, sensors, or control board can lead to inadequate ventilation and condensation.

Symptoms:

The homeowner observes excessive condensation forming on the laundry room walls, particularly behind or near the GE UltraFresh Vent System washing machine. There may also be a musty odor present.

Possible Causes:

Vent system malfunction
Incorrect vent hose system
Restricted airflow in the vent system
High humidity in the laundry room
Overuse of fabric softener
Cold water supply temperature too low

Solution:

1

Disconnect the washer from the power outlet.
2

Inspect the vent hose for kinks, clogs, or damage. Replace with a new 4-inch diameter hose if necessary.
3

Ensure the vent hose is properly connected to both the washer and the wall vent, using clamps for secure connections.
4

Check the wall vent for obstructions, such as lint buildup or debris. Clean using a vacuum with a hose attachment.
5

Verify the vent fan is operating correctly. Using a multimeter, check for 120V AC at the vent fan motor terminals when the vent cycle is active.
6

Measure the laundry room humidity using a hygrometer. If above 60%, consider using a dehumidifier.
7

Adjust the water temperature setting to warm or hot (around 100-120°F) for optimal vent system performance. Consult the user manual for recommended settings.

Safety Warning:

Disconnect power to the appliance before performing any maintenance or repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. High voltage is present inside the appliance; exercise caution.

Prevention:

Regularly clean the vent hose and wall vent to remove lint and debris. Run the vent cycle after each wash. Ensure adequate ventilation in the laundry room.

Expert Tip:

Enter service mode by pressing and holding the Start/Pause and Soil Level buttons simultaneously for 3 seconds. This allows you to manually activate the vent fan to test its operation and airflow.
