Can you jump start a compressor with a garden hose?
« on: June 08, 2021, 10:26:10 PM »

35-year-old Carrier split system blowing warm air from the registers.  Ugh.
No icing on the evaporator coils, but I could hear the coolant flowing in the lines.
Just topped off with 4 pounds of R-22 a month ago.
Waiting for the HVAC tech to arrive tomorrow, so I thought I would go out and rinse off the compressor unit.
Found it completely silent, but very hot.
Thinking it's time to replace a 4-year-old Chinese capacitor with an American one.
Sprayed the outside - not too dirty since I gave it a good cleaning in and out last year.
Then I sprayed through the top, having fun making the fan spin.
Wisps of steam, I was definitely cooling it down.
When all of a sudden.... buzz, buzz, buzz, start.
Nice cool air flowing inside.
Left the hose spraying on it for a couple of hours and the cooling is working, at least for now.

Is it possible that cooling the compressor with water and spinning the fan motor jump-started this beast?
