Heating coils seem to not be activating, prohibiting blower from coming on. Checked input/output of service disconnect breakers and voltage present. Thermostat seems to trigger relay in unit but nothing happens. This is a 2 wire unit in a mobile home.

Re: Intertherm E1EH-015HA FURNACE no heat

Sounds like a downflow electric furnace? If so it sounds like you have 15kw worth of electric heat, you might have a defective heating sequencer, witch is what they call a dual on one plate.

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.

I have an intertherm furnace model number 901282 and it will not heat my house when i turn on the thermostat it starts but just blows out cold air pleases 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

If it's only a two wire system, it should be on the R/RC and W. Fan should kick on automatically.
Not too familar with that unit
A is usally for a heat pump pick-up coil or heating element
Pay attention once you've rewired the t'stat. Make sure the blower goes on automatically. The most it should take is apx five min, even if house is really cold
Also, check the heater. It may have way more options for control. You will just have to run new t'stat wire to take advantage

Anyone have a wireing diagram for a nordyne E1EH-015HA

Intertherm does not offer a wiring diagram for the E1 series anymore. So I have included a link to the E2 series. They are very similar and you may find this service manual helpful for whatever problem you may be having.

I have an Intertherm heat pump model number E1EH-010HA. Last night we had a bad storm and our electricity went out and we had a water leak, now out heat pump isn't working. There is power to the...

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.
