2. Excessive current due to line spikes or lightning strikes.

The cause of fuse failure must be determined and resolved before installing replacements. See 

“Replacement Parts” 

on 

page 73

 

for fuse details.

To Replace a Door Switch (Microswitch)

1. Disconnect furnace from power supply.

2. Remove the four top screws on the front dial plate.

3. Open the front dial plate. Remove the shield which covers the door switches.

4. Disconnect the wires from the door switch to be replaced. (Note connection and placement of 

wires to Microswitch.)

5. Remove the two screws from the Microswitches.

6. Insert new Microswitch and secure with screws removed in Step 5.

7. Reconnect wires to new door switch. Replace wire shield.

8. Close front dial plate and install screws.

9. Reconnect to power supply.

10. Test operation of door switch.

To Realign Door Switch (Microswitch) Bracket

1. Disconnect furnace from power supply.

2. Loosen the screws which retain the door switch bracket on the bottom left side of door.

3. Move the bracket closer to furnace to make switch engage sooner. Move bracket further away to 

make switch engage later. (Lightly tighten screws between each adjust to hold bracket while you 
test the switch.)

4. The switches should click when the door is approximately 1" from being completely closed.

5. Tighten screws when bracket is positioned correctly.

6. Reconnect to power supply.

7. To test the operation of the door switch: turn the power switch on, set the control to a setting high 

enough to keep the control from cycling, open and close the door; the mechanical relay should be 
heard when the door is about 1" from being closed.

To Realign Door Lock

The door lock plunger interlocks through a port at the bottom of the door. If the plunger is missing 
the port, realign the door by adjusting the position of the door hinge pins in the door hinge brackets.
