Compressor?

[ClassicDave]

Weather King 3 ton heat pump, R-22 Bristol compressor
system not cooling, 5 years of no issues.
Found bad capacitor replaced capacitor, rheems plastic capacitor bulged on top, replaced cap everything looks normal in pressures 85 suction 295 discharge pressure, split 20 condensation out of drain.
House is warm 82, outside 90.
2 hours later compressor out on thermal overload.
Go back to customer,
Cool compressor restart, same pressures but I came back after 2hrs running suction pressure drops to 50psi, discharge the same at 295. Suction has no condensation nor is there any water coming from condensation pvc line when suction pressure is low

could not get the super heat in range adding or subtracting refrigerant. Compressor goes out on thermal.
after getting compressor out of thermal, pressure starts around 85 and had to button it up do to thunderstorm and darkness.

What was supposed to be an easy capacitor change out turns out to be a lot more.
Is it refrigerant related or compressor related. Seems like every time these symptoms leads to a compressor, but a running dead compressor is always the hardest to confirm so I'm looking for opinions.

TXV indoor coil?

[newoldtech]

I agree with the bald one. Some sort of restriction. Your numbers dont look like any bad compressor that I've seen.

"20 degree split"

Referring to RAT vs SAT?

A little on the high side, especially considering the RH inside must have been quite high, we moving enough air? Did the coil freeze up?

Restriction.check out my thread from yesterday. Help with numbers

thanks guys,
went got a txv replacement.
Got to customer's home, pressures were 25 suction 205 discharge pressures.
recovered refrigerant back to compressor, that went well
removed txv, cleared both lines with nitrogen.
Put new txv on then pressurized system with nitrogen.
then vacuum.
Turned system on, and compressor was out on thermal overload! 45 minutes of water on the compressor the compressor comes on.
pressures 100 suction 200 discharge, suction line condensate all the way back to the compressor. So look likes the txv was the main issue.
I will check super heat tomorrow, discharge was rated for 225 for proper charge but I believe it will settle out with a cooler indoor temp.

Compressor was out on overload after your replaced txv and charged and let it run? Or was it out on overload when you tired to start it?

[ClassicDave]

skid,
I pulled the refrigerant back using the compressor, locked it down and pulled the disconnect to the condenser and shut off the breaker to the air handler.
I took the old txv out, put the new one in. Did the nitrogen and vacuum and then put the disconnect back in and the compressor was out on thermal. It took me an hour to cool the compressor, more than it took to replace the txv.

Update,
Yesterday after getting the house to 71F the next day the house temp went up to 78.
I assume the compressor went out on thermal overload.

after 3 days, We replaced the duel capacitor with service call for $200 we then gave her a superboost, and now I gave her a new txv all that at no cost.

We ended our relationship today on good terms, I said it may be best for a second opinion and she agreed.

She needs a new compressor, this call just didn't feel right and it is unusual to have 3 major problems all at once.
capacitor, txv and compressor

The customer chose this brand do to being the cheapest and it only last 5 years the warranty ended 3 months ago. This customer was are first customer for new equipment and unfortunately we let them over rule our recommendation of a better quality system back then.

Since you changed the TXV, I assume you changed the lld, but I wonder if the old refrigerant was contaminated, thus creating a ll blockage? Dirty condenser coil creates high head.
