I need some direction on troubleshooting my HVAC heat pump. I have recently purchased an older home with a newer heat pump was installed. There was no power to the thermostat.
Called repairman and he stated I needed new thermostat wiring from the thermostat to the inside blower unit. The repair company wanted $3,000 to run a new 20 ft. thermostat wire. I felt that was excessive. I ran the new wire myself replacing the connections one at a time, color by color.
The yellow wire was connected to the "Y" terminal in the thermostat. However, the yellow wire was just terminated in the blower unit. The outside unit will not energize nor run. It does not seem correct that that wire should just be terminated in the blower unit. Help.
