On-off Switch 3870001

1. Removed the heater box from the wood frame.
2. Unplugged the wires to the switch.
3. Removed and replaced switch.
4. wiring diagram is white/red/black positions 3/2/1 on the switch.
5. Installed heater box into wood frame and secured it.

Remove the screws from the back of the heater that hold the heat box in the wood casing. Then remove the support brackets from the left and right sides that you can see on the back. Then remove the one long screw from each wheel bracket on the bottom. Flip the heater back up right and pull the whole metal heat box from the wood case. Lay the heat box on its left side and remove the screws holding the right side cover on. Note the location of the wires on the old switch and them remove them from the switch. Squeeze the upper and lower tabs together and push the switch out the front. The use of pliers may be required. Assembly is the same but in reverse. Use caution tightening screws as to not to over tighten them. The metal screws will strip very easily. Good luck and have fun.

Only problem I had was I put switch in up side down and wires code was wrong, just switch two wires around. Should of marked or remember that, other that that worked great,

Removed old switch and replaced it with new one.

1. Removed the heat box from the cabinet.
2. Removed the side panel closest to the switch.
3. Squeezed both tables on the switch and pulled it out.
4. Disconnected three wires and installed the new switch connect wires.
5. Tested the power before screwing the side panel on.

Took case off the heater, took panel off side, took old switch out and Put new switch in and connected using the diagram we made. Most difficult step was putting new switch in....and we were probably being overly careful!
