Hello all.
Just replaced a compressor on above model (outdoor unit).
About a year ago the same compressor had burnt wiring to the compressor common.
After replacing compressor all seemed ok except on heating there was quite a large range in high side pressure between the outdoor fan switching on and off.
I am aware that on heating the indoor coil sensor determines what speed the outdoor fan runs at or whether it runs at all but I am not sure of the exact values.
Unit is r22 model
high side pressures;
(on heating)
fan stops running at 60C SCT (340 PSI)
fan starts running at 43C SCT (227 PSI)
Fan was on high speed all the time it was on.Never went to low speed.
I am thinkin the indoor coil sensor might be reading incorrectly. But I need to know what parameters the outdoor fan should operate at.
Thanks in advance.
