Hello, I am trying to troubleshoot my central AC not cooling.
It will turn on and the air feels cool initially, but then it just feels like it's blowing at the air temperature.
Replaced the air filter, the intakes and vents inside are clear, the outside coils are clean, I looked up online how to test the capacitor and it tested good.
There were some bugs behind a control board (031-09104-000) which comes up as heat pump defrost circuit board, where the bugs were the pcb board around the resistors looks brown, the ac unit is older so I am debating ordering another board or just having someone come put to look at it.
Thank you for any help!
