Most likely cause would be a 'stuck' sequencer. The sequencer will be similar to the one in the pic below. Luckily, they are relatively cheap (about $20).

I have a e3eb012h when I turn to fan only why do my heat strips come on.


Sounds like a stuck relay. Try turning on cool, measure temperatures in ducts. See if the heat strips are coming on every time the fan turns on not just when on fan only

My coleman Mach Rv air conditioner with built in heat strip keeps tripping it's internal circuit breaker when running for any length of time. Just replaced heat strip with new one experienced same issue. I...


There should be an overload protection device in series with the low voltage wiring(t-stat wiring) Is it resting on the heat strip or too close to it? It is a saftey device to shut off the heat strips if the fan quits or a fire in the heat strip section. check that or by pass it, if it stays running then ur thermal protector is bad, couple bucks at the parts house.

Carrier 38CKC042300. oUTSIDE UNIT FAN WAS TURNING REAL SLOW. ac UNIT IS OFF BUT FAN TO OUTSIDE UNIT IS STILL TURNING. sHOULD NOT BE TURNING AT ALL WITH AC UNIT OFF


The outside fan may run if the unit is in defrost mode this is normal for most heat pumps it is there way of trying to keep the outside unit from staying iced over so the next time the unit runs it will have air flow through the coil and the ice will not be there to prevent air flow.

Heat strip does not provide heat but fan is running


It will provide heat but it is a very slow process with a heat strip. It is limited to about 1500 watts. With the big fan running, it feels like there is no heat. Give it time.

If you gave it time (ran for a couple hours and there is NO difference) - post a comment here and I will tell you what you must do to test it.

Thanks for your question

I have a 3 ton Coleman heat and air pump and when I turn the air condition on the heat strip comes on at the same time


If you are calling for heat and the thermostat is set for 2 degrees higher than room temp, the heat pump and strips come on.
When the room temp and stat temp are less than 2 degrees the strips turn off.
That is, unless the installer wired the t-stat for the strips to stay on.
If they are coming on in the air/cool mode then you have a bad heat relay or a t-stat wire shorted.

Intertherm air conditioner split unit


you need to know if the heat strips are energized by a contactor or relay as opposed to a heat sequencer. as a general rule the contactor or relay clicks shut as soon as a call for heat is made and the fan is energized by the stat at the same time . instant heat strips and instant fan. if the heat strips have a sequencer it may take up to 90 seconds or so before the sequencer heats up then clicks and puts power to the strips and the fan motor at the same time. the high voltage usually feeds from the strip side of the sequencer through the normally closed side of the fan relay. if you changed the stat and didn't switch the fan setting switch to elec, the fan will not be energized by the stat. if it is in the gas position, you have told it that the sequencer is bringing on the fan and of course it won' t if you don't have a sequencer.. this is tough stuff to trace even for an experienced pro cause its interconnected so dual fan speeds can't be energized at the same time. most likely you have a new digital stat that was not programmed correctly to bring fan on in heat. good luck
