You said it yourself. when an electrical device is running it produces amps, with every amp is a unit of heat. breakers are heat sensitive as well. so you might want to consider a new breaker. newer breakers are made out of better materials that are able to displace heat more efficiently. or check to make sure the screws on the terminals where the wires go in are tight. if there is a loose connection that will increase the units of heat traveling through the termination. or, worse case scenario, like when all hope is lost. splice in some more wire, correctly, emphasis on correctly, and relocate the breaker. perhaps use insulation around the breaker, non flammable of course.

SOURCE: electric furnace wire heating up

you should have a 3- conductor # 6-3 copper wire running to this 60 amp breaker @ the furnace to the panel if this is not the case you should replace this with a # 6 as of now as it is a fire hazard as it is and needs to be fixed at once , # 10 -2 wire is only good for 30 amps and a 60 amp breaker will not trip under fault condition and you could have a fire , if you need further assistance on this let me know and i will try to help

Intertherm FEH-015HA. Why does it keep opening breaker?


Avery, if the breaker is properly sized, there is something in the circuit that is causing higher than normal resistance such as possibly loose connections on one end or the other. Check the 'minimum circuit ampacity' (for circuit A and possibly circuit B) on the heater tag and make sure the correct size breaker has been installed. That should be a 15 kw furnace and could either be a dual circuit or a single circuit heat strip. Fifteen kw correlates to approximately 60 amps at 240 volts.

TURN OFF THE POWER and check the connections inside the furnace terminal block for discoloration and tightness. If its a dual circuit, there will be two breakers to turn off. Check to see if it is a dual circuit and if so, see if someone has paralleled those two circuits together inside the furnace. If so, you have to make sure the appropriate single circuit wire and single breaker has been installed.

It is usually recommended to run the separate circuits to the furnace instead of paralleling them together.

Good luck and whatever you do...BE SAFE ABOUT IT .

Intertherm furnace burner comes on, but blower does not. If I turn thermostat off then back on until it clicks the fan will then come on. It does not do this all of the time, just now and then.


Furnace burner and heat element are not the same. I think the fan time delay, a sensor that turns the fan on when this sensor senses heat, is shot and needs replacing, for a furnace type heat ( gas heat)

The furnace is blowing warm air even if the thermostat low.


The only thing that tells the unit to come on and off is the thermostat so I would definatly say it is it. When you turn the system back on, does the a/c run normally? If it does, then it's the problem with the heating side of the tstat. Also, does the fan come on when you put it to on and then turn of when you switch it back to auto? If it does, then the system is working fine, its the t-stat. Let me know if you have any more problems.

Intertherm funace limit switch controls the heater coil


Take the part into a heating and cooling repair business and have them order that part. You will also need to have the model number and brand of the furnace you have. I'm sure they will order one for you.

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.
