Hello all, I have a second stage compressor failure on this unit. It is a 180,000btu pack unit with a 5 and 10 ton compressors. These are fixed bore evaps. R22. There are 3 of these units on a church and when running work very well. They are only used during meetings twice a week. They are 6 years old and well maintained. I have heard of air flow problems and control board problems causing short cycling of the frist and second stages of the compressors. The second stage compressor is shorted to ground and pops the breaker if the compressor is started. Have any of you run into this problem with these Trane units. THANKS
