Servicing the fan motor
assembly

To replace a fan board assembly:
1. Remove the filter and the fan

board access panel(s), depending
on unit size and configuration.
The panel and the drain pan are
removed at the same time. The
fan board appears.

2. Disconnect the motor from the

auto transformer or from the
electric box (disconnects the
connector and remove the snap
connector of the side panel) , the
electric heater from the fan board
and unscrew the solid-state relay.
Push aside the bundle of wires.

3. Remove the 2 screws on each

side panel. (4, Figure 62)

4. Remove the fan board.

Note: If the option “Accessibility

pack” has been chosen:

1. Remove the two lower screws

from the fan motor assembly (1,
Figure 62) and unscrew (1/2 turn)
the two screws at the top (2,
Figure 62).

2. Push the fan motor assembly in

order to remove the screw from
the key hole and the fan motor
assembly is released (3,
Figure 62).

Reassembly

Same operations in reverse order.
