To Realign Door Strike
1. Disconnect furnace from power supply.

3. Move the bracket closer to the furnace to make strike engage sooner. Move bracket further away to
make strike engage later. (Lightly tighten screws between each adjustment to hold bracket while
you test the strike.)
4. The door switch 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, open and close the door a few
times; Note an acoustic click of the switch during opening and closing of the door. This check
must be done when the furnace is heating and the cycle light on the display is illuminated.
