A/C Window unit 10K
|
|
|
| this unit is a 1.5 years old and it cuts out the external
overload....jumping out the exteral OL, the compressor runs, but you
can feel it heating up and it will eventually cut out the internal
overload. I know these units are probably not worth replacing a
compressor..
But I was wondering...is it possibly an internal problem w/ the
compressor or could it be a low freon problem causing high pressure,
and then cutting out? Is it worth putting a line tap on it to check
the pressures to see? (I don't mind 'tinkering' w/ it, but I don't
want to put any money in it)
Thanks for your advise!

Low on refrigerant causing high pressure problems?????
"but I don't want to put any money in it"
Wouldn't the tap cost money? :-)
BTW, do you hold an EPA card? If not, your not allowed to work on the sealed
system.

External overload? internal overload? Whatinthehell are you trying to
describe? There are no "overload" switches in an A/C. A unit may have high
and low pressure switches but "overloads," no.
Clean the filter and the ice will stop forming on the evaporator. The unit
will perform normally after that (until the filter gets dirty again).

Try telling Copeland, Tecumseh, Bristol, Danfoss, Carlyle, etc that their
compressors have no 'overloads'. LOL

But what if, its not the filter?

They possibly have pressure limit and temperature limit switches not
"overloads." None of those folks actually measure a compressor load, e.g. the
work the compressor is performing. A breaker would come closer to be an
actual overload switch...

But it most likely is, even if you didn't think of it.

I agree clean and should run till dirty again window units rarely have
overloads just temp shutdowns

| More likely a dirty condensor. Dissemble the unit and clean both
coils.
Incidentally, please don't ever remove or bypass an overload
protector. It's there to protect you.

What exactly is this "overload protector" measuring? There are breakers and
there are fusible links. There are no actual compressor load protectors
either internal or external that the orginal poster claimed.

CY: Amperage, and I believe also temperature. I'm sure of
amperage, though. Most compressors I service, the overloads are
external. One brand (Copeland?) puts the overload internal.

| AFAIK, all window units come with a 5 year compressor warranty-- some
with P&L on the "sealed system". If the unit is actually no more than 1
1/2 y/o, first try and talk to the store mgr where the unit came from
and see if they will just replace it. I have an old friend who bought a
small unit from HD, and at just under 2 y/o the fan quit. He took the
cover off and found that the whole bracket or whatever the fan assy was
mounted to had rusted away. He took it back to HD and raised some hell
and got a new unit. Good luck Larry

And none of those devices actually measures load on the compressor. They
infer load which is not the same thing. Does amperage equal load? No, of
course not. Amperage *may* indicate load but it doesn't necessarily measure
it. Got it?
The original poster described a condition typical of icing caused by low
air flow through a dirty filter. Compressor load is most likely not an
issue.

| The OP said the compressor was overheating and cutting out on IOL. That
is NOT caused by low air flow across the evaporator--due to a dirty
filter or anything else. Low air flow across the condenser however is a
distinct possibility. The OP said the unit is 1.5 y/o. I wonder if that
was a typo, as he also said the unit was not worth spending money on.
IMO, he should clean the condenser thoroughly and see if that makes any
difference. If it doesn't and the unit is indeed 1.5 y/o he should check
into the warranty as I suggested in a previous post. Otherwise, he shoud
not mess with it and just go buy a new one and be done with it. Window
a/cs have joined microwaves and vcrs as throwaways. They cost no more
now than they did 30+ years ago. Larry

No he didn't say that the compressor was overheating. Read it again.
