Update: it was the capacitor. Heat works now. Thanks for Ace Hardware who had one in stock, worth the 2x cost for that.

Of course this has to happen on the coldest week of the year, right after the big ice/snow storm...
Woke up this morning, house is a little colder than usual, vents blowing cool-ish air. Supposedly aux heat is working but I only feel warm air come out on occasion (I think it's cycling or something). Not sure why it only seems to come on for a bit at a time.
Went out later today to investigate. Outside fan does run and is blowing upwards (normal I think).
When it starts I hear a 2-3 second loud hum. Then a pause for a few seconds, and the fan starts (perhaps a bit slowly?). I let it run for a bit and checked temps with an IR thermometer; coils are the same temperature as surrounding case and other parts and both refrigerant lines are the same temperature.
This unit apparently has a dual run capacitor, which I am suspecting has gone bad. Parts are cheap but won't arrive for a couple days. Guess we're using space heaters for a bit...
Am I on the right track? Or am I looking at a bad compressor? Or something else?
