Our two year old Amanna refrigerator went into constant no-start,
thermal trip, cool down , start attempt, thermal trip cycle. Good by
$200 worth of food.



This is still under warranty, right?

If yes, simply tell them to replace it with a new unit under warranty
that has the proper compressor in it, not to try to patch it with
excessive starting current which will surely make it fail down the
road...hopefully for them, out of warranty.

The compressor design is faulty for higher pressure gasses and they tried
to get away with using up the old compressors, but failed.

I also question the pressures. Did he actually hook up a set of
refridgeration guages to the refridgerant lines of the fridge, if it had
any to begin with? Without reading the pressures on real guages, he
can't tell what's wrong with the refridgerant loops in it. As a fridge
has a fixed orifice into the evaporator(s), not an expansion valve like
your AC, the slightest piece of leftover manufacturing crap left in the
lines works its way through the system until it nearly blocks the tiniest
constriction in the loop...the evaporator's inlet orifice/capillary tube.
This causes high head pressure and very slow bleed down, even though what
goes past it will cool the fridge, eventually. A blockage of this type,
easily seen on a pressure guage as high head pressure on the high side
and low suction pressure as the compressor sucks the evaporator dry on
the low side, will cause hard starting because the head pressure doesn't
drop by the time it needs to start again, cooling so poorly. The only
way to troubleshoot this is with guages connected. Most home fridges
have no guage ports so we can make it cheaper.

AS it has operated a lot with stalled or near-stalled compressor, the
windings in the compressor have been overheated, over and over, causing
much stress and cooking the winding insulation from just too much
current, even after it's running. The replacement fridge won't have this
half-burned-out compressor, its most expensive part. It's the same kind
of failure mode that (ON TOPIC!!) would be caused by you buying the
trawler they forgot to put oil into the port engine but caught it in time
before the engine locked. I wouldn't want that stressed port engine
that's under warranty, would you? Same idea, here...(c;

Just call the nice man and tell him to bring your new fridge and take
this one back to its defective manufacturer. It's only fair....

"Hard Start Kit" my ass.......
