Hi FABG,

I would suggest starting with getting the high and low side pressure of the system. If the freon is low, the compressor will not come on. However, when you replaced the compressor did you pull the system into a vacuum to evacuate all moisture and then refill the system? Not only does this pull all moisture out but it ensure there are no leaks if it holds a vacuum.

Let me know what your pressures are and we can go from there. Thanks
