Blower fan works , but no heat or Ac.
Hello my unit is Heat pump from about 1998. The previous owner had it installed so I have no book to read from. The Ac worked fine all summer and I fired up the heat 3-4 times already. I decided to clean up the inside of the unit do to the poor sealing on install(no tape used to seal). After cleaning the unit out and resealing with foil tape. The blower fan works fine, but no heat or ac. There is a kill switch on the front panel door which is placed properly, so I don't think it is that. Other than pulling a wire accidentally the only other possibility I can think: I had to remove a sensor to take off the back panel of the unit. The sensor had 2 wires running to it. I vaccumed it off and reatached it as it it was before. I will work with the unit more tonight. Any advice would be greatly appreciated. Thanks
