Trane- compressor not turning on when calling for AC
When the the thermostat in the house calls for cooling the fans turn on but is not blowing cold air. Checked the compressor and it is not turning on. It has power but not turning on. When pressing the middle part of the relay, part# 3100-15Q242, the compressor turns on.
Do I need to replace the relay or am I missing some else that is causing it to not turn on?
