Frustration with my roof air

[hypoxia]

My clamp meter can record max-min amps and or voltage, no need to stare at it. I would think most meters have that capability now. Did you post the make and model number of the heat pump, I didn't see it?

The (most likely) reason for A/C Breaker tripping is 1) dirty coils, causing high head pressures; 2) next is failure of the fan/ blower/ motors, which can be simple electrical (capacitors failed or changed value) or windings shorting when hot, or bushing/ bearing dragging causing extra motor load and low speed/ or motor seizing). Easiest/ cheapest for troubleshooting is 1) visual inspection of/ changing of capacitor/s, 2) to include checking motor for binding by spinning by hand, and if no improvement, followed by coil cleaning. Any of above can include issues of insect or rodent nests.

Very good advice!
