SOURCE: Blower on my Intertherm Model mgba keeps cycling

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.

Good luck!

SOURCE: Intertherm MGH-056ABFC-91 won't kick on. Just

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.

SOURCE: Where are the furnace filters in my older furnace?

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.

Got Intertherm Model # MGH-055AB.. It lights for ap 10 seconds goes out then goes out... Over and over again does not stay lit long enough for the blower to start running?? ANY IDEAS HOW TO FIX IT ?


You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. If the s3 comes on then you have an issue with the unit and i would get a professional to help.

The blower should come on after ignition occurs. When the blower comes on first ignition will not be activated as the thermostat signal shows the heat is on. This happens when the blower relay is stuck in the on condition

I have an old Intertherm gas-fired furnace, Model MGH-055AB which ceased operating last night. It was quite warm when I arrived home, and when I set the heat up a little, began to hum, but the fan would...


Tom P's answer is generally correct: The motor start capacitor is usually not the problem. However, in some cases, particularly on older furnaces, where there were capacitors of certain make and production run will prematurely fail. This happened in March on a mobile home HVAC unit where both the blower fan and condenser fan motor capacitors failed open circuit. Both caps were of the same Mfg, and production lot.
Here is a suggestion (for you or an electrically inclined friend): Locate a substitute motor capacitor having similar Mfd (or MF) and Voltage ratings. Remove power from the unit. Reach into the blower squirrel cage and spin it to verify that the shaft is not frozen. Pull the wires from the existing capacitor noting color and location. Connect the wires to the substitute capacitor and secure it place. Apply power and turn on the blower. A no start? Motor replacement time.

At the furnace, jump the R and W (or T and T) terminals on the circuit board or gas valve. Make sure the door switch is closed with some electrical tape. By doing this we are forcing the unit to start. If it does fire, you have either a bad thermostat or a broken wire to the thermostat. If it does nothing, look for a bad fuse, check for 24 volts going to the gas valve, an open limit switch or 120 volts at the transformer.
