GE PDE9900 manual Active Vent

Active Vent

The active vent consists of the fan, motor, housing, and vent louver motor.

The active vent helps to reduce the noise level and heat loss when in the closed position. The control module supplies +/- 12 VDC to the vent louver motor. The control module reverses polarity to drive the motor in a clockwise or counterclockwise (open or closed) direction.

The vent closes 8 seconds after the main pump is switched on during the first fill cycle and opens during the drying cycle (heated and non-heated). The vent is open during cooldown periods or when the unit is not in use.

If the vent is closed and the door is opened during the wash cycle, the vent will open. When the door is closed again, the vent will remain open for 8 seconds, then close again to finish the cycle.

It is normal for water vapor to come through the active vent during the dry cycle. The active vent can be opened and closed using the Service Mode.

The vent louver is held in place by a single screw.

Remove the motor from the mount by rotating the motor 90° in the mount and sliding it out between the tabs.

Note: The gear in the mount is held in place with the motor.

Note: This also applies to the Rinse Only cycle. Since heated dry is not an option with Rinse Only, the fan will run for approximately 4 hours before turning off.

To access the vent fan and motor, remove the door panel (see Door Panel).

The vent fan and motor housing are held in place by:

4 long, silver Phillips head screws.

2 short, brass Phillips head screws (see photo).

Note: Foam with double-sided tape holds the conduit in place. The foam tears easily if pulled during removal of the housing.

Six Phillips head screws hold the fan and motor to the vent housing.
