Wiring diagram
(OP)
The units at my plant have had switches by passed relays staight wired and numerous other problems. Most units are Trane American Standard and Carrier. The unit I am trying to straighten out now is an Amana model ARHF36U01B, the indoor coil needs to be replaced but the plant is low on funds. I am trying to keep the outside coil from freezing up and that's where the problem is. the defrost timer is not adjustable and seems to have been partially straight wired. I have not been able to find the outside thermostat, there are several places in the defrost circuit that looks to have been straight wired. I am in need of a wiring diagram for this unit so I can straighten out everything. Goodman\Amana say they no longer have diagram for this unit. Is there a universal system I can wire in for the defrost to operate or does anyone know where I can get a diagram?





RE: Wiring diagram
Yes there are universal defrost boards you can buy. Get you one and a defrost sensor. It will have a diagram with it so you should be able to wire it in with little problem. Should be able to get on at any decent HVAC Wholesale house. Hope this is helpful
