For this evaluation I showed up to the customer's home and the system was not running at all. I have power coming into the breaker and passing through the breaker however nothing was going to the transformer. I'll inspecting the system I found that one leg of 120 volts at burnt up at the contactor and the other leg was partially burnt not passing power through the contactor back to the transformer. I showed the customer what I found and explain both those parts would need to be replaced in order to get the system up and running. Once I replaced both of those the system ran like it should, and I tested it in both heating and cooling with no issues. I left the system on heat and set to 74⁰.
