Everything Dead on split system A/C
I have an older Carrier split system heat pump. It was hooked up to an analog White Rodgers thermostat and I upgraded it to a Trane Taystat 540 Thermostat. After everything was hooked up I tested the fan and the heat pump which all worked well. When I forced the Em. Heat the entire system went dead. I reinstalled the analog Thermostat to test and the fan won't run, no heat, no noise, nothing.
I didn't hear a pop nor smell any electric burning in the furnace closet. When I removed the panel holding the transformer, heat coils, etc. I noticed that one of the heat coils is severed. I tested the transformer and got 52v on the output (double what it should be?). Is it possible that the heat coil being severed when I turned on the Em. Heat caused the entire system to go dead? I ordered a new set of coils and transformer. I know the heat coils need to be replaced now, but am I barking up the wrong tree thinking this was caused by the transformer?
