It was last Sat. the outdoor temp. was 92.When I came up from the basement,about 10:30pm,it was 85 in the house.So I took off the white rodger stat,and jump cooling ,and still the heat was going,in the heatpump mode.So I went outside, to check the coil on the reversing valve,and it was OK,so I pulled off one side of the coil wire from the defrost board,and put it right on the coil teminal with the compressor contactor,and I had cooling.It was a fast service call,and I was lucky it worked.So that would mean my defrost board is bad.This is a five ton janitrol heatpump.
