How to test?
I'm not sure if there was any damage to the compressor when the failure occurred (Dec 2009),
the system lost it's R410A and a few ounces of oil and seemed to want to run, even with very little pressure..
Almost no pressure.. Did anything burn up inside the compressor??
So, how can I test this thing?? (Before investing in more hardware)..
When I was doing the repair, I noticed oil on the floor pan and inside the thermistor
wire insulation tube, that looked nice and clean, clear too..
Maybe even usable for a test.?. If there is enough left inside..
I have 28 oz of R410A. That's about 40% of the 4.3 pounds (69oz) needed, if used with a 20-30ft line set.
So, could I build a very short line-set/HX test set, using some copper tube
to sit a little coil in a bucket of water, while running in test mode?
I have the flare couplings, and would only need some copper tube.
♦ Refrigerant Piping Discharge (O/D Inches) : 1/4” (0.25")
♦ Refrigerant Piping Suction (O/D Inches) : 5/8” (0.625")
AND, some kind of copper coupling from 1/4 to 5/8..
If not available at HomeDepot, maybe a 5/8 copper cap and drill a 1/4"
hole in the side of the 5/8" tube and braze in the 1/4" tube?
(Maybe using CO2 flood)?
Am I missing anything?
Comments please.
Cheers,
Rich
