I have an Intertherm electric furnace model E2EB-015HB new in 2002 in a mobile home. The blower comes on when I put thermostat to "On Ventilate" but the heating unit will not come on when thermostat raised.

This is the kind that has the heat come on for about 4 -5 seconds, then turns off for say 1-2 seconds and then cycles on and off for about 4-5 minutes until warmth is achieved. The unit has an add on a/c that when it comes on it stays on continuously until cooling achieved.

I cleaned the wall thermostat coils of all dirt and clicked off and on the circuit breakers inside the unit at the bottom but it still won't come on.

Is it possible that the relay sequencer went on this unit? Any suggestions?
Thanks.

More than likely you have a defective heat sequencer.

Put thermostat on heat

I put it on the heat setting and nothing happened. No heat.

THEN

More than likely you have a defective heat sequencer.

How big a deal is a heat sequencer to change out? My son has a room full of tools and is handy. Where is this located please? Plus he has a good quality continuity tester.

Not that big of a deal. You can test the sequencer but I would locate it on the diagram that is on the door of your furnace. Follow the wiring diagram to check for voltages.

How big an expense is this also? We're going to check out part with volt meter tester now. Be right back.

I looked at the wiring diagram at the bottom on the panel holding the circuit breakers. The legend said
CB Circuit Breaker
E = Heater Element
IFS - Fan Switch
Cont - Contactor
LS = Limit Switch

I don't see any sequencer listed on this list. If I called a tech - what kind of $ should I be looking to part with to get it fixed? I don't want to mess with anything if I can't see an actual part listed or know where it is.

Your unit might not have a sequencer. Let me see if I can look up your unit.


here is your diagram

Try to jumper out the LS = limit switch and see if the unit runs. If that does not work go to next.


Next check for 220 volts at the electric element. =E

Take care when working with electric. You can have the power off to test the limit switch. Just make sure you take the wires off the limit for the continuity test.The element test can be
done with power on taking great care of power off and check for continuity.

It is also a possibility that the contactor has failed.

Yes, this is the same diagram that is on the front bottom panel of the unit. It looks like the whole entire bottom is able to come out after a few screws are removed and the blower fan unit comes out with it also. It looks like quite a production to just get the panel off as the electric supply line is in front of this mess.

Thanks also for the diagram also as we couldn't exactly take a picture of it and now we have one.

Also, for the last 2 nights a helicopter has flown over head very low where I live in the wee hours of the night. Yesterday there was a furnace repair truck around the corner, today we counted two repair trucks go down the same street. Where I live there is a circle of about 50 mobile homes. My furnace stopped working around 4AM the time of the heli. Long story about the heli but we think it has something to do with ELF like waves as it is a small, black chopper like a "little bird". We've monitored their transmissions via scanner when they were doing some kind of for want of a better word "medical experiments" out of a double rotored chinhook. Next thing you know the scanner reports heart attacks, seizures galore, etc and this area is a quiet rural town that has little or no medic alerts from one week to the next. So we kind of think the furnace not working has something to do with their latest ELF experiments.

It is the government and they are there to help you. LOL

Are you near Roswell.

LOL No beautiful downtown Ohio not far from a little Mom and Pop airport that they like to use. Believe me, we've seen it all here and heard it all here. Not too far from Mansfield and Dayton, home of the make some new fangled machines and try them out on unsuspecting populace.

Seriously, I did look online and found that the parts are not too expensive. It's just the problem of getting the cover off the danged thing in the first place. What is the typical mark up on parts? 20% or 50%? I know service call/diagnose problem is around $75 here. Unless I can figure out a way to get the cover off I'll have to bite the bullet. At least I know it has to be either circuit breaker, heater element, fan switch, contactor or limit switch as there is virtually nothing else to the unit!! Apparently I lucked out with a unit that does not have a bunch of expensive parts to it!

You are up near Wright Patterson AFB ? They have some neat toys there. A relative worked there but he could never tell me what he did.

He won't either. They have some dandy toys for big boys there. Their latest toys are in the chinhooks that have thingys on the bottom that remind you of yellow DOT lights. We heard one of them complain that there was "nothing coming out of the back" and that they would have to go back to base and get "it" adjusted. When they got "it" adjusted they flew over and chattered away that it was coming out of the back okay. That night we heard on the scanner about 5 people in this little town had seizures, heart attacks, high blood pressures, vomiting, etc. Normally this place is dead as a doornail scanner wise but yet the chopper said it wanted to "monitor" the emergency frequencies. And no, I have not been watching too many X-Files and no, I have not made this up. The emergency calls kept coming in that night. We've heard them in action several times and know that it is not a coincidence about the heart attack proliferation calls.

I was wondering if their ELF stuff shorted out my entire system or just the lower voltage stuff. I figure the unit was on last night and got fried whereas Thurs it was in between the cycle and didn't get fried. I find it most interesting that 4 furnaces in a small area would suddenly need servicing. It's not a coincidence.
