My “American Standard” Heat pump is ten years old. Currently, the interior fan is blowing but the outside unit is humming and the exterior unit fan will not come on. It’s hard to get a technician out as it’s 97 F and they are all out on calls and days behind. I understand a very common failure point is the capacitor. Careful to work safely, I’ve extracted it and am headed into town to get a new one. Wish me luck. Any other advice on what a non tech can check? Here’s a few photos. I have since cleaned things up. The pine beetles like to hide out here in the fall and they croak over the winter. Thanks.
