I think those are the venerable Danfoss compressors.  You can find more
info in the link below.

http://www.kollmann-marine.com/modules.aspx

Mine has had problems which include a fan that needed replaced.  IIRC,
120mm computer fan ~$12 on Amazon.  It also had a failure of the fuse
holder which appeared to have a poor solder connection causing it to
overheat and slightly melt.   Simple problems which were cheap to repair.

If you want more help troubleshooting just PM me.

Thanks Len

I'm real close to going for a replacement.  Sure Marine here has good 
pricing, though I don't think it is $15 USD.  Maybe I should get the 
price of a unit in CAD and decide if it is worth a trip to BC to pick 
pone up there.  Anyone know the Nova Kool dealer in Vancouver?


We have a club cruise this weekend and then I'll be taking Alera to 
Bell Harbor, in downtown Seattle, for the week for a few conferences 
I'm attending.  So, I should have a pretty good idea if the problem 
was just a one time thing or a total system failure.  Either way I'm 
pretty usre that it is not a coolant issue and can see a new refrig 
in my future.

Tom, As long as you didn't defrost with a sharp knife and the 
compressor fan is clean it should run well (unless the board is 
fried). Mine had a leak and it only takes about 1.1 ounces to refill 
and it's easily over filled so best to vacuum out and weigh the new 
charge in. Like Josh says check wiring too. I was able to refill 
mine and install a new computer fan to get a couple more years out 
of it but replaced it with a new unit this summer. The new unit is 
modern refrigerant and has an adjustable output. It uses less power 
too. The old one was 1990s vintage and used R12 which isn't 
environmentally friendly. If you can send it to nova kool for a 
cheap rebuild, it may last longer than fixing it yourself but you 
can't keep bending the copper tubing. If your compressor is located 
where mine is under the aft cabin wet locker, you need to lose the 
heat and cold beer is important! IMHO installing a new unit is 10x 
the cost of repairing the old one but well worth it. Ask yourself 
what you would do if it was in your own kitchen at home. It doesn't 
owe you anything by now and you can't buy parts for that vintage any 
longer. I think it was 1100$ CDN so what's that $15 USD? Lol.

Re: Stus-List Nova Kool Recharge

[Josh Muckley via CnC-List]

I would not mess with the refrigerant till all other options are
exhausted.  The Danfoss compressor package is pretty bomb proof.  The
electronics that the resellers attach are less so.  If you go to the
danfoss website you can figure out how to bypass the electronics and wire
it the way danfoss expected.  This will provide you an opportunity to
troubleshoot the electronics separately.  I found on mine that the 2 fuse
holders had bad solder connections creating a hot spot and intermittent
operation.  The previous year I had found the little computer fan not
running on the condenser.

Stus-List Nova Kool Recharge

[Tom Buscaglia via CnC-List]

I called the Nova Kool tech support folks.  They said that the 
refrigerant system is sealed and never loses pressure absent a 
leak.  After discussing my issue, which is kind of intermittent,  he 
concluded that it is probably the electronic control module going 
away.  This part is no longer available.  No offer of service 
made.  He recommended replacing the whole thing.


That being the case, I'm not sure what I have to lose by recharging 
it, aside from the cost of the hose/gauge and a can of refrigerant...

No house calls.  You have to disassemble and ship to them.  The fittings
are hermetic and lossless so you just wrench them apart and ship.  They fix
and recharge and ship it back.

Re: Stus-List Nova Kool Recharge

I picked up a set of these at a flea market years ago,

 

http://www.ebay.com/itm/refrigerant-gauges-/112150576806?hash=item1a1cb1fea6
:g:OzAAAOSwmfhX4KSC

 

used it on home, shop, car and boat refrigerant systems - one use can pay
for it.

Your system should list the low and high charges, just squirt refrigerant
into it 'till you reach the high charge.

My NovaKool LT200 refrigerator has been under performing and after running
through a list of possible issues I am convinced that it needs a refrigerant
recharge.  I have checked into it and it doesn't look difficult.  But I am a
little concerned about either under charging or over charging the system.

Can this be done without purging the system with a vacuum and will the gauge
on the hose be sufficient to get the right amount of refrigerant into the
system?
