Re: intertherm furnace

That is a stack limit switch. You are not venting properly. Is your unit power ventilated or gravity fed?

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.

I have a 1987 Intertherm FEH-015HA electric furnace. The issue I am having is that my blower will not shut of unless I pull the disconnect. My thermostat will operate the heating elements like normal,

You most likely have a bad fan limit / cycling switch. If you kill the power to the furnace see if you can trace the wires from the motor to where the connect to the switch. It looks like a round button with tabs sticking out of it for the wires to connect. Mark down where the wires were connected and take it to a HVAC business or furnace supply house. Be sure to have the model off the furnace with you so you can get the correct parts.

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

The Intertherm AC Model B3BV-030K-A is blowing warm air

If you don’t see any frost on the suction line or big line on the furnace
(that goes from the furnace to the outdoor unit) and the filter and coil are clean then you are probably low on refrigerant.

Check for a open limit switch caused by a dirty filter or poor air flow
