    I have an Intertherm Ultraflex elec furnace in the mobile/manufactured home I just bought. The furnace is a model: FEH 015HA -03, date code 870821. We came home from vacation to find it not working (no sign of power outage). I have no way to test for power to unit. I reinstalled the old thermostat; neither thermostats can get the furnace to work. The fan/drum turns readily. All ideas welcome...

Is this a 120v motor, or 220v? If you checked for power, I assume you kind of know your way around a meter. When checking for power, don't check to ground, check the line. You could have power going in, but unless its going back out, completing the circuit, or missing a leg, in 220v case, it still will not work. Also, most heaters have some sort of delay, so after you hook it back up, and the burner heats up wait a few minutes for the fan to come on.

Intertherm furnace burner comes on, but blower does not. If I turn thermostat off then back on until it clicks the fan will then come on. It does not do this all of the time, just now and then.


Furnace burner and heat element are not the same. I think the fan time delay, a sensor that turns the fan on when this sensor senses heat, is shot and needs replacing, for a furnace type heat ( gas heat)

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.

No problems, would like to find out the best way to remove blower for cleaning on an intertherm gas furnace mgh 075 ina mobile home


Generally ther is two screws at the base of the blower housing which hold it in place, remove the screws and pull, slide the entire assembly out. You will have to disconnect the electrical wiring to the blower and possibly the limit switch on the side if equip.

If there are only two wires going to the thermostat? Then you will not be able to use a Digital Programable stat. Intertherm and Coleman furnaces do the switching different than regular furnaces. They use the switching from heat to AC at the furnace with the rocker switch. They use the thermostat to either break the connection or make the connection. They use a heating only thermostat.... Hope this helps

Your furnace will either have circuit breakers or fuses at the bottom in the panel below the blower. Also, there MAY be fuses in the disconnect box outside that gives power to the heatpump. Intertherm furnaces are famous for leaking water onto the left side of the electrical panel in the furnace which is also convieniently where the low voltage transformer is located. If you consider yourself electrically competent, check to see that you are getting 240v to your transformer and if you are the check to see if you are getting 24v out of the transformer. If you can't find the problem in any of these steps, I would recommend contacting a qualified professional to check the system out.
