Thread: Trane Voyager cool fail problems
09-24-2011, 04:14 PM #14Have you checked the UCP to see if there is a newer revision? might not help but maybe. It will tell you the lastest revision and what issues were corrected. Bad thing is you can't flash it, you have to get the whole board. The last one I bought was over 400 bucks.
I have a lot of information on these micro controls. If you would like to check it out let me know.
Then one time it was a bad compressor contactor. They were burnt just enough to cause it to be intermittent failure. Replaced them and it solved the problem.
