I have a Whirlpool Gold GZ25FSRXYY7 Refrigerator that I purchased used. The person that I purchased it from said that it was not cooling and the repair man told them the system needed vaced, flushed and refilled. Initially I refilled and the compressor was short cycling. (turning on for 30 seconds and then turning off) I had another project to work on so I left it for a few days. I returned, vac the system, refilled and the compressor worked perfectly. The pressures were correct and the fridge cooled down to the proper temp.
I opened the doors to put in the drawer parts, moved it a couple feet to get better access and when the compressor kicked on again it was short cycling again. Checked the pressures and the high side was reading the same as the low side. (About 3 psi) The compressor is not pumping, it just runs for 20-30 seconds and kicks off. I don't think I could have had all that pressure leak off and it was still holding 3 psi which is what it would go down to when the compressor was off.
My question could this be do to the power control board, the defroster censor, the main board. I have checked the wiring harnesses and it looks like the one to the compressor has been altered but the strange thing is it worked perfectly for 14 hours.
One thought that I was considering was when I opened the freezer
door for a few minutes, the defrost censor got messed up.
I am looking for someone with years of experience so I don't just keep replacing parts.
