I solved the problem by adding a Off-Delay Timer and doing away with the heating relay that I setup to replace the 4-7 Control Board. The timer is adjustable for the amount of time to allow the fan to run, I set it at alittle over 2 minutes. This gives the elements a chance to cool down before the f...

I have finally gotten my Nordyne E1EHA-015 re-wired, it helped when I found the wiring diagram for the 4 to 7 Control Box. Now since I replaced the control box with relays here is the problem that I have run into, when the heat signal (24V) is stopped the fan turns off but the elements are still on ...

Sorry I Have been out of town, but ordered a relay and it came in Tuesday. I will be keeping the Air Con.. I haave a wiring diagram , but it only shows the heat side of the system. I scanned it in and posted it with my other post. I also have a Service Manual for the unit. It has line drawings for t...

On the Control side of the contactor there are four terminals (no markings). One goes to the G terminal on the control board ( wh...

Well I found a couple of wiring diagrams and by following them I got most of the wires back in the right places, (even the ones the tech incorrectly installed). After puting the right I can get the top element to come on but no fan. As you can see by my next post another tech installed a contactor t...

:shock: HVAC repairman replaced blower on unit ($375.00), but could not get it to work, so 2nd service man called in. 2nd Repairman, said problems must be in control board, so he installed a fan contactor and set up the motor on high speed. Which is okay for cooling, but motor is supposed to run on ...

:( A couple of months ago on a cool morning I turned on my heater, and noticed a burning smell. I opened the top access panel and could see flames on the top element. I called a HVAC repair man who told me that he could stop by in a couple of days. To make a long story short since I needed air more ...
