We have an old (c 1980) GE 'Frost Free' fridge
CY: Ah... generally expensive brand.
the freezer and the fresh-food areas cool down only to about
evaporator fan runs, and seems OK. The evaporator coils are
not so cold it hurts to touch them. The defrost heater is
CY: 50F is a bit too warm.
The compressor runs, but shuts off after less than 10 mins.
compressor is quite hot - you can touch it, but it would
burn, if you
applied pressure. (The compressor fan is running, but shuts
with the compressor.)
- Is that too hot for a compressor? IIRC, my father used to
say that a
motor that you couldn't touch was too hot. Even if true,
does the same
apply to compressors?
CY: I think your Dad is right. Sounds like the compressor is
running way too hot.
- Would they have a 'self-resetting' temperature cutout on
compressor, where it would keep recyling after cooling down?
CY: Yes, there is such a device.
- Any other reasons why the compressor would shut off, when
is nowhere near the setpoint temp?
CY: Either too hot, or too much current draw.
CY: As you didnt ask for ideas what is the problem (or how
to solve the problem and make the fridge work again) I'll
limit myself to answering your questions.
