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

I have an early 80's mobile home with an "intertherm gas atmospheric furnace" pilot light is lit but can't get the furnace to "fire". Seems as though the limit control is stuck open. ...


If your pilot light is lit then I would first check your thermostat. Make sure it is on heat setting and fan is on auto, turn stat up to where it should be calling for heat. If you don't get burner to light remove front cover from thermostat and see if it has a mercury switch, if it does move temperature selector up and down and see if you can see a spark in mercury switch vial. If y ou cannot see a spark remove screws that attach t-stat to base.Remove carefully and disconnect wires that go to r and w terminals on stat base. Temporarily connect these two wires together. This should make burner light if you have power to thermostat. If burner does light disconnect wires and replace thermostat. Also if you have a volt meter check across these two wires and see if you have power there. Should be around 24 volts a.c. If your thermostat has a fan on setting try that. If fan runs you know you have power to furnace The gas valve needs 24 volts to operate and inside the electric control box in furnace there is a transformer to step down 110-120 supply voltage to 24 volts. If transformer is working you should be able to hear a low buzz or humming sound. You can also check across gas valve terminals when t-stat is set for heat, you should read about 24 volts. If you have 24 volts to gas valve and it is not opening then you need to replace gas valve. The main purpose of the limit switches is to turn blower on when temperature in heat exchanger reaches fan on temp,shut off blower after burner shuts off and heat in heat exchanger reaches fan off temperature, and limit if temperature exceedes set point without blower coming on. I hope this helps you. Thanks

I am changing out my intertherm thermostat control. the blue wire is hooked up on B, not on RC, can you tell me why


Because it doesn't belong on RC.

B means "blower" in the antique language of the tradesmen, but nowadays it means "reversing valve". RC means "red cool" or "put 24 volts here to power the cooling system".

The blue wire was not connected to RC because it would not bring 24 volts to the RC terminal.

The AC or Heat will not turn off once set temp is reached.


The yellow and the blue wire are commonly interchanged. as long as it is hooked up the same at the gas heater. It sounds like you did it right.

Elec. intertherm FURNACE


It would help if I knew what type of system you have, lets start with the thermostat. If you disconnect the wires to it, does the heat turn off? I have seen thermostat wires pinched inside the wall, thus bypassing the thermostat controls altogether and it would run constantly. If you send a reply, tell the type. Wall furnace, central unit, heat & cool, gas, electric or heat pump. If you dont know tell me how many wires you have at the thermostat and the colors. You should know this, as you have changed it.

Intertherm to Honeywell thermostat


Typically if you have a yellow wire in the "y" terminal blue is used as common or "c". As far as your jumper from rc to rh, that will depend upon what type of heat you have. If all of your heat and cooling come from your packaged unit outside, yes you will need the jumper. If this does not work maybe you have a bad breaker or transfomer.
