ok, thanks, maybe it's me that's not explaining the issues well enough. In any event the heater techs are working on it now and consulting with others so hopefully they'll figure out the issues soon.

thanks again.

We replaced both sequencers and the unit began working as expected. I did have a heater tech install them and verify the unit was working. Worked for 2 or 3 days and now the heat pump has stopped coming on? We are beginning to wonder if we should just buy a new unit. Do you have any suggestions on w...

thanks,

electrician thinks it's the sequencers. Hopefully that will fix it.

Intertherm E1EH-015ha When the fan on this heater is in the ON position, there is a hum and the fan is turning very slowly. When in the AUTO position the fan comes on and appears to run normally. The unit was functioning normally a few days ago. We began troubleshooting an electrical issue concernin...

I think we've determined finally that the outside unit is not a heat pump, unfortunately. I guess we are going to look into installing a heat pump or replacing the entire system, or finding an alternative. Have any recommendations on where to look for heating/a-c systems for mobile homes and what si...

that's what we thought, should have more wires. we tested voltage to the unit from the t-stat lines - there is 24v in A/C mode but nothing in heat mode. we are at the conclusion that either this has not been wired to use as a heat pump or despite what the label says it is not a heat pump. thank you ...

We haven't gotten a chance to go back and look inside the unit, I will post when we check it out.

There are only 2 wires going to the outside unit, a red and blue.
thank you!!

Outside Unit Brand: Goodman
Outside Unit Model Number: CK42-1C

thank you, we'll take a look again today.

So we cracked the heat pump and all we found inside was a capacitor, relay/contactor, fan, compressor, cooling lines. The unit clearly states it is a heat pump on the model information tag, but there is no defrost board or other control electronics in the outside unit. There are 2 wires that lead fr...

New problem, We fixed the inside heater with a relay (621867 Relay), we didn't replace the sequencers as the relay was testing bad and when we replaced that the inside heater works as expected. However, we noticed that the outside heat pump does not come on. We did test the A/C and the outside unit ...

thank you,

I looked through all the manuals and searched for the model number but did not find one for an E1EH-015ha model, am I just not seeing it? Or is an E2 series manual sufficient?

thank you for your help,

First question: In heat mode the heating element appears to function but fan does not come on when the switch is on auto. When the switch is flipped to ON the fan appears to work fine. I'm assuming this is a sequencer problem after reading similar posts of other models? Can you verify and point me t...
