SOURCE: 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.

SOURCE: Intertherm heat coils won't stay off until breakers off,thermostats are off

it is the heat sequencers. it happens all the time. replace them wire by wire to keep it simple. they are located behind the metal next to the breakers they look like this: cdf7518.jpg

Having changed the fuse and breaker tell me there is a major short in you furnace. 240 volts is a lot of amperage and a very delicate job to attempt to help you directly. I have found that any intertherm dealer near you will be happy to help solve your problem. Yes, the sequencers are possible reason but 50 amps at 240 volts is what concerns me. Did your transformer burn out also?
Let me know what you think and if you would like, I will locate the correct source of help. Thanks, JT

Best things to do is find your Return grill in the home.
Get a measuring tape and measure the Hole size with the grill removed, Or filterback grill whatever the case.
Then simply go to a home retailer with the size, or in rare cases you may want to consider a Hogs hair washable filter that can be cut to size, to fit it perfectly.

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.

Look at the "klixon" style heat actuated switches mounted on the fire box of the heater. One of them is not working.

Sounds like a bad contactor in the circuit. They are usually power to close (on) and spring to open (off) so it should go off automatically. A tech can open unit find right relay and replace it or try contacting these folks with your serial number:

Disconnect assembly has overheated and needs replacement. where can I find a new puul-out disconnect assembly for my intertherm furnace model FEH-015HA-03

Those parts are readily available. You can get them at or google and have your model and serial number ready. You are talking about the pullout at the bottom left of the unit correct. If you have a breaker within six feet of the pullout you can remove it. But be very careful and turn off all power before you try.Rus

I have an intertherm electric furnace FEH-A020, with multispeed blower installed when A/C added. My problem is blower operation. at the end of the cooling season with fan set to auto operation the fan ran...

The model of T-stat you gave comes up as a discontinued model on Honeywell's web site, but it looks to be a manual stat that type of stat would have to be wired with a summer winter switch with electric heat, allowing it to turn on the fan with a call for heat. If yours is a programmable T-stat you would need to select electric heat or in the installers set up change the default setting for fan from unit controls fan in heat to thermostat controls fan.

vulcan bonaire comfort control External natural gas electronic ignition 2004. ISSUE: Fan blowing only cool air continuously. Forced to kill power to stop it. model is one of the following. MB514E,20E or 30E. Going by mech drawing parts list. i can confirm what type of sensors i have cleaned with very fine sandpaper. flame sensor PN 5441603SP and IGNITER ELECTRODE PN 5441602SP The fault code i see is described as the following. There are x4 LED's. Sequence Left to Right. LEGEND: 1 Flame Sensor 2 Pressure switch 3 OverTemp 4 Diag. R Red G Green S Solid Colour B Blinking LED Behaviour. In order 2RS & 4GS Until i hear ignition. 2RS & 3RB Duration: split second 2RB,3RS & 4GB Duration: split second 3RS & 4GB Duration: Until it has completed blinking x4 times. 3RS Duration 4 seconds Repeat last two mentioned behaviour. in my own opinion, as a safety feature, the unit thinks that it has overheated or is about to. so kills the gas and force feeding cool air to heating components to save it from frying. Does this mean i have fault 04 if so does this mean i may have a faulty igniter or flame sensor or maybe a faulty as described in the mech drawing SWITCH OVER TEMPERATURE 120 degrees celsius. Am i correct here? Is this the over temperature cut out switch? if no one can really pinpoint which part requires replacement, can you at least, in sequence advise which parts to purchase? so then ill just try my luck. i wonder how to properly test if flame sensor, igniter, over temp etc is faulty with a multimeter. do i just perform a continuity test. I wonder what other parts can i test related to this fault im getting.
