MOTOR ASSEMBLY REPLACEMENT
(Motor, Thermostat, Rheostat, Wiring Harness)
1. Unplug the heater from the 115V AC outlet.
2. To replace the motor you must first take the cover door off. Do this by removing the two screws holding it in
place.
3. Next, you will find a wire cage protecting you from the electrical components of this unit. By looking to the
right of the ash pan, you will find the two screws that hold the wire cage in place. Remove the two screws.
You will also find a screw at the bottom right of the wire cage. Remove this screw. It will be easier to
remove the cage if you first take the knob and nut from the rheostat that is hooked to the cage. Lay the cage
aside.
4. To remove the motor simply unhook the wire servicing the motor. Take the two screws holding the motor
bracket out.
5. Gently slide the motor out, and while pulling it out moving the rear of the motor facing you from right to left
in a counterclockwise motion.
6. To replace the thermostat follow steps 1 through 3 and then gently push the thermostat up out of the bracket.
7. To rewire the motor, rheostat, and thermostat see Figures 10.
8. To replace the motor turn the motor so that the 4"x4" air discharge opening is pointing toward the rear of the
stove. The flat part of the motor housing is turned up. With the air discharge opening pointing in the 2
o’clock position, start in toward the unit rotating the rear of the motor clockwise. The air discharge opening
of the motor housing fits in a cavity in the rear of the unit that will direct the air flow to the proper location.
Make sure the air discharge opening is located firmly in the opening. Replace motor bracket to the motor.
9. Hook up the wiring to all three components if you have replaced or unhooked them.
10. Replace rheostat on to the screen housing. Fasten the screen housing to the vertical bar to the right of the ash
pan. Also fasten the motor bracket to the bar at the same time.
11. Replace screw at the bottom of the screen guard. Replace cover door.
12. Plug heater back into a 115V AC outlet.
