If the transformer is you must have a low voltage short.
does your transformer have a trip switch that you can reset?
You could try to use a hair drier and dry out any water residu in the compartment. but my guess is you have a low voltage short.

Blower works no heat


Most electric furnaces use time delay relays called sequencers to turn the heating elements on and off. If your thermostat is calling for heat, the sequencer coil should get 24 volts and the contacts will close in a pre-determined order bringing on each element individually. If the sequencer coil is getting 24 volts and the elements are not heating, then one of the following issues is going on. 1. The sequencer contacts are not closing because it is defective. Therefore the heating element is never getting proper voltage (usually 208/230V) 2. The heating element may be broken. 3. The high temperature limit switch for the element may be open, not allowing proper voltage to the element, or 4. The element is not getting proper voltage because of a blown fuse, tripped breaker, or broken wire. I hope this helps!!!

Intertherm model# FEH-015HA It is no longer blowing heat


High limit safety device is probably tripped, it should reset automatically, also check other safety's for tripped condition, they look like small round device located in a variety locations through out the unit with two wires to each one, some have small push button resets located in the burner compartment area. If all the safety's are reset and check out OK the main control board may need replaced. One of the most common causes of high limit safety device trip is lack of air flow, Dirty filters, evaporator coils, malfunctioning blowers, closed supply air registers etc.
Note: High limit safety switches also go bad after being tripped to many times.

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 a Intertherm model# FEH-015HA It is no longer blowing heat


I'm a dealer for a Nordyne product and I was on the website trying to find your model number and I can't find your unit anywhere even in archives. Can tell me if the a/c coil sits on top of the unit? Also, can you varify the model number? But anyway, even if Nordyne doesn't make the heat kit anymore (which I doubt) you can restring the heating element anyway. You need to remove the heat kit from the system and physically look at it to determine if it is bad. You can do a continuity check as well. The heat kit is easy to remove. On most Intertherm models, the heat kits sit right behind the breakers near the bottom of the air handler. Also check to see if the tstat is actually calling for the heat to come on. That can be done with a volt meter. Also check that the sequencer isn't faulty as well. If I could have the correct model number, I can pull up a wiring diagram of the unit and tell you exactly where everything is located. If you can varify the model number and also the serial number, I can call Nordyne monday morning and find out exactly what you need and if they are still making the heat kit. Just let me know what you would like me to do.

Nordyne electric heater


If you have 24 + volts between common and w or w2 when your thermostat is calling for heat, you might have a or a couple of defective heat relays or sequencers.

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.
