UltraTroc Air Dryer Failure
This thing is a little over a year old and failed. Compressor is locked up not shorted. I lost the potential relay first due to high current. One of the terminals fried. I replaced it and ran good for a few days. Now the compressor just hums and goes off on overload. My question is should I do a reverse purge on the cap tube once the system is open and before I replace the comp and filter? I have and do a lot of 12 chillers and never practiced this on these systems. They seem to run forever after a comp change. This is only about the 4th time I've dealt with a 134a system and wondering if I should consider it's habit of blocking cap tubes. Parts are expensive for this unit and I really need it to hold up longer then this. Thanks!
