Hello
My first post !
Sorry if this question has been asked before..
On my chest small freezer(5 cf) the compressor comes so hot and then the protection (above relay) comes on. Sometimes the compressor does not start and draws about 7-8 amps.When it start it draw 4 amps. After awhile it stops dur to high temp: the top of the compressor reach about 140 degrees celsius ; When it start ok, the cold eventually comes ok inside , but this, to avoid the protection to comes on, i have to place a small fan beside the compressor. When it runs i hear a noise inside around the evaporator , i think.There is no external fan. Also the side of the freezer (above compressor ) feels hot.Sorry for this long post !
Thanks for your help . Jean-Marc , Canada.Hello
it s a Frigidaire brand freezer made by WCI, model CN08 ; it does have a run capacitor external (12uF) The cap, protection and relay were changed: same results ; the resistance compressor reading between C- S and R are Ok; BUT: there is some continuity between any compressors pins to ground (about 3 ohms to 12 ) This seems to be bad , i think ?

If your getting resistance between the windings and a good earth then it sounds like your comps windings are breaking down
Yes you are right; I can buy a compressor for a good price now: the thing is it is a R134 instead of mine : R12, and i Wonder if this is a task i can do myself (i do have access to freon also) Is this compressor replacement a big job you think ?

In short no you cannot use a 134a instead of 12, the oils are not the same.
Without trying to sound rude or negative if you dont understand refrigerant (freon) pressure to temp charts and/or the science behind them you should get a tech out to replace, im not sure where in the world you are but here in the UK we work on strict guidelines set out by governing bodies and no one should be working on refrigerants without correct qualifications.To do the comp change you need a tech to reclaim, replace comp and drier (if fitted) pressure test, vac out to correct scale, decay test and rise test and then and only then the unit can be recharged with refrigerant.
