Upon arrival, I found the 24v fuse was popped. I hooked up my short finder and found that the outdoor unit would not continuously run. I proceeded outside and found the low pressure switch would periodically only pass 7v/24v through it. I jumped the switch out of the wiring and got it to run. After a little bit of time, the unit stopped working. I proceeded to further test the indoor and found one of the contactors for the heating kit is shorted out. It is currently reading 1.4ohms. I unwired the bad contactor and the system would run with not vault with the low pressure switch bypassed and bad contactor wired out. We will need to locate the part to be able to price it. Customer wanted to replace the contactor when we replace the low pressure switch. I left the system off with the first contactor unmounted to allow access in the future. I took pictures to indicate the failed contactor.
