I have a Nordyne Model # E2EB-020HA, SER # E2E010105593. Have had problems with this unit. Had a heating contractor come out 3 times, but still have same problem. You turn the ac on, it runs good for a while. When it cuts off, the heating coils come on and stay on, but blower does not come on. Basically every time we use the ac/ have to turn the breaker off so heat does not come on. I am wondering if the heating part of this unit can be permentally cut off. But still have the ac work like it is supposed to . Thank you for your help

Thanks for the help, on the Nordyne E2EB-020. With this unit there is also a a/c unit on top of heating unit. Miller model # C3QA-042U-B, ser # C38010400471, need wiring diagram, or trouble shooting guide for the a/c unit. Thanks again..

Here is the information from the outside unit, that you requested, Nordyne model # S3QA-042KA, serial # S3A010401576

Here is a manual for your unit.

You have a probable low voltage wiring problem or a control device is defective. You will have to electrically test these areas to find the problem. If you know about electric testing just use the diagram for your unit included here. If not leave it to the pros.

Please, please don't keep starting a new thread to reply to your own question. No one can properly know what you are talking about, this is not a chat area. If you want to provide additional info, place it as a reply to your original posts.

I have merged your three questions into one, I hoe it will make sense to those helping you.
