Intertherm furnace not getting hot after motor swap. PLEASE HELP

I have a mobile home that is equiped with an intertherm furnace motor ith a compatible motor from cc dickson in Gaffney, SC because the original was locked up. Now it blows MUCH harder but it won't warm up. I can restrict the air flow and get it somewhat warmer but the furnace runs non stop. It is a 3 speed to where my orginal motor was a one speed but I have it hooked to the red wire for the slowest speed possible. Can anyone help me please as I have 2 small kids that''s having to deal with this also. Thanks so much for the help. Brad

You already diagnosed it yourself. The motor may have been the same physical size but it operates at a higher speed and doesn't remove enough heat from the furnace. You need to have the right motor installed period.

I HAVE A MODEL UFG-101AG-4 SERIAL # 800H2 INTERTHERM FORCED AIR FURNACE FOR MOBILE HOME OR TRAVEL TRAILER THAT I DONT KNOW WHATS WRONG WITH IT?


OK. Let me answer you, even if honestly I don't have any idea about an INTERTHERM FORCED AIR FURNACE. To get any answer, to a problem, you should describe your problem. Just telling that you don't know what's wrong with it is simply no enough information, even for a star expert in your INTERTHERM FORCED AIR FURNACE.

Intertherm gas furnace in mobile home..igniter comes on then nothing tries to fire byrners but nothing


by igniter I assume you mean the thermocoupler. are you turning the control button to run after you light the pilot light? Normally when those furnaces quit it is the thermocoupler that has quit. Get a new one and leave it in the furnace compartment as a spare.

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

When I turn on my furance or ac the blower is always on even though the fan is set to auto. When it is on heat it never gives off any hot air, so it never warms up the house. I had someone look at it and...


If this is a mobile home furnace they usually have a two stage gas valve. Generally they just have a delay in opening fully and are convertable from L.P to natural gas or vice versa. It is a possibilty that the gas valve is bad. If so it will have to be replaced. First I would have someone check your thermostat to see if that is what is causeing the blower to run . does the burner ever light? I wouldsuggest that you hire a service tech. who is knowledgable on intertherm furnaces. I don't recommend anyone who is not trained to change gas valves,because of safty concerns. I hope this helps you some. Thanks

Intertherm Furnace Will not stay on


Your furnace is likely getting too hot check your filter. make sure the fan is running. if you have weak air flow you may have a blocked heat transfer coil. you should have your heating and cooling system serviced yearly by a qualified company to inspect and test equipment.
