Question about Intertherm Heating & Cooling
It could likely be the fan control switch. Open up the cabinet, and you'll see a metal box, roughly 7x9x2" inside, with the blower switch located on the top edge of it. There are usually two screws holding the lid on. Remove the two screws and the lid, and you'll see a couple of eye-shaped items side by side with 2-3 blue or orange wires running to them, each. They might have numbers on them such as 6263360 or 6263370. These are the limit switch and control switch, respectively. If your fan keeps cycling on and off, try replacing the control switch (6263370). The new part number for these switches are 626336 (limit) and 626337 (control). The control switch is also one of the cheapest (less than $10) places to start.

There is probably more than one limit switch. I'll have to get a wiring diagram of this unit. See if you can follow the wires from the wires from the limit switch and see if they go to another limit switch. Also you can put a jumper wire on the red wire and white wire on the unit outside and see if ti comes on.

On these of Furnaces the filters mount on the door. Remove the door you will notice grill on front. There should be a track on the back of the front door to slide filters down. Should take 2 filters.
