terminals blown out


What would blow out the terminals on a compressor? This has happen twice about 7 years apart. There was a snow storm, but we never lost power that we can tell. We did not have to set clocks or anything like that. But we heard a noise then lots of hissing and looked outside and saw freon going everywhere. Two of the three terminals have been blown out of the compressor.

Thanks for the help

Did it happen on the same machine? If so they probably did not clean it up properly after the first burnout and left acid in the system which pooched this one. Time for a new system or some SERIOUS decontamination.

very strange. sounds like the wiring outside or in the unit is getting wet or a short and grounding out the unit. if the breaker/fuses are too large or the unit not grounded properly that may be a problem. sounds more like a low voltage ( main supply) to the unit problem to me.

Here is my theory, When the power flickers the unit cuts off and tries to restart with high head pressure, because it just cut off. Maybe?

If power flickers off. The defrost boards 5 minute delay should prevent the compressor from trying to start until the delay times out.
