the motor and reducer unit was mounted with the motor under the speed reducer, the main input shaft seal failed and filled the motor with water soluble glycol oil (sticky brake fluid essentially) that caused a lot of damage to the motor, but it still works :D
This is a Danfoss TL4A 240V domestic refrigeration compressor that I have cut open with a grinder to show its workings.
Under normal operation, the low temp, low pressure gas from the evaporator coils is drawn into the unit via one of the suction tubes on the housing and is compressed into a high temp, high pressure form before being discharged through the thin silver tube, and into the condensing coils where the heat is removed and it becomes a liquid again.
This unit had approximately half a cup of polyester oil (POE) in it for lubrication.
12V damaged LCD shows no sign of harm apart from the fluro back-lights being dim due to the low temps.
Vertical lines and panel de-lamination was there before I got it.
condensation on the PCB's would cause problems after a while.
