went to a service call that another tach in my company was at, he replaced the reversing valve (from looking at it I believe he had trouble with the welds, may have overheated). Any way upon arrival the unit was running and the complaint was that the house would not cool the house below 76. This is a heat pump and the electric heat was not on. I had a slightly hogh suction and high superheat. A repair had been made on the cap tubes (solder all over the cap tube). I pulled the bullet (all clear) and went to start the unit up vut the system would only run for about 10 seconds - pressures stabilizing - then the comp. draws LRA and goes out on overlaod every time I tried to start it. The unit is 15 years old but the comp. is only a year old. I can't keep the unit running long enough to check the reversing valve. I believe it is the valve or the cap tubes but can't say for sure. Any suggestions?

Are you able to monitor the discharge pressure between the Reversing valve and compressor?
Xenos.
The best way to escape a problem is to solve it.

went back to the call and found that the bad reversing valve had damaged the comp. Had the comp. replaces and every-thing was fine.

what do you mean by stabilizing
what are the pressures at the suction and liquid lines
you have and outdoor txv and a check valve if you are running cool check the check valve it could be clogged up
