Important: Use only factory authorized replacement 

parts.  If you lack the necessary skills to properly 

perform the installation, you should not proceed, but 

get help from a qualified service technician.
Tools required: Phillips Head Screwdriver.

Removing the Air Intake Chamber Box:
1.  Set the gas control valve/thermostat to its lowest 

setting by pressing the “COOLER” and “HOTTER” 

buttons together at the same time holding for 1 

second. Then press the “COOLER” button to the 

lowest setting (Figure 45).

2.  Turn gas control switch  to the “OFF” position 

(located right side of the gas control valve/

thermostat) and turn off the gas supply to the unit 

(Figure 46). 

3.  Disconnect the electric connection by unplugging 

the transformer from the wall outlet (Figure 46).

4.  Remove the manifold cover/ outer door from the 

unit by depressing on the lower portion and pulling 

outward.

5.  Unplug the 3-wire pressure switch/fan/sensor 

electrical connection of the wiring harness from 

the gas control valve/thermostat by depressing the 

lower portion of the snap clip to open and pulling 

down the connector (Figure 47).

6.  Using a phillips head screwdriver remove the 2 

screws of the air intake chamber screen (Note:

7.  Remove the air intake chamber screen by lifting 

upward and outward (Figure 48).

8.  Please take note of the wire position routing 

around the fan inside the air intake chamber as 

this wire positioning will need to be duplicated 

upon installation of the fan in the new intake 

chamber box.

the chamber (Note: save these screws for 

reinstallation later) (Figure 48).

10. Lift the fan up and outward to remove from the air 

intake chamber (Figure 48).

(Figure 48). 

12. To separate the electrical connection of the fan 

and wiring harness: press down on the back 

portion of the close pin lock of the electrical 

connection while pulling the connection in the 

opposite directions.

13. Using a phillips head screwdriver, remove the 4 

screws securing the air intake chamber box to the
