DE Defrost Dampers
Check the dampers during scheduled maintenance
inspections for shaft wear, end play, and sealing
against air flow.
Position the damper so that air flow is stopped on
the top and bottom with the solenoid plunger
bottomed.
To adjust the damper:
1. Remove the damper assembly from the
evaporator.
2. Disconnect the solenoid rod from the damper
shaft.
3. Energize the solenoid (apply 12 volts to the
29A or 29-2 circuit) and check “Distance A”,
the distance from the upper mounting hole to
the end of the solenoid rod when the solenoid
is energized.
Control Box Side—Distance A = 3.36 in.
(85.3 mm)
Compressor Side—Distance A = 2.09 in.
(53.1 mm)
