The AB refridge on my 1998 Hunter 376 has started to occasionally stop cooling. It appears the compressor has occasionally quit running (cooling fan continues to run). I turn the power off and wait 5 minutes and turn it back on and it runs fine for a week or two. I had the condenser fan go out a few months ago so I replaced it it a factory replacement. I Put it in so the fan pulls air from the condenser away from the compressor. Is this correct? Or should the fan "push" air into the condenser toward the compressor? And could this be the problem? Thank You. Bob

Max cooling is directed air which in a normal
environment would be directly at the hot part. Don't let car radiator systems confuse you ... they have plastic hoods that forces the flow of air through the radiator. If you don't see something like that you are probably kicking out on overheat. but I have no real knowledge of air cooled compressors ... water cool is another thing. Vic

I would guess that blowing air is the best way.
Bob: It would make sense to me that you would want to blow air over the coils. Like Vic points out a cars radiator has a cowling to direct the air, plus the car is moving (normally) and the fan does not have a large effect when you are at really moving. I would just try reversing the fan and see how that works.

AB Fan
Bob What direction did the old one blow before you took it out? I replaced mine a few years ago, with the help of this forum. I remember that when I got the new fan unit the fan blades were "backwards" (i.e., different slope) on the new fan than the old one, but it turned out that the blades rotated CCW rather than CW, so it worked. I checked on this before I permanently installed the new fan. As I recall, the fan should blow out over (through) the coil, the compressor has nothing to do with it. The only purpose of the fan is to cool the (condensing) coil, not the big black compressor. The AB manual is very helpful in this regard, to understand how it all works. If you don't have one, there may be one to download from AB website. There is also a "basics of refrigeration" on some link from who-knows-where that explains the basics - any basic web search should get you there or other sources. Not the place or space here to expound on those theories. Give up on the responses from the guessers, go check it out, and hope that AB weighs in on this. If not, call Gary at the AB factory, they're great people and very helpful. Stu

Agree with Stu
We have an AB Super Cold Machine unit on our 376. The fan moves air towards the compressor. Personally, I like the solution of reading the manual or calling tech support. There is lots of good advice on this web site and in the archives, but not all of it is good. Some times I just want to be sure. AB has always been very responsive. One of the things they did tell me was that on most 376's there is no escape for the discharged heat. I modified the set up slightly using a computer 12v fan. Drilled a 2+ inch hole in the settee, installed a vent grill (found at WM) the size of the fan. Good luck. Scott

compressor stops
The problem is most likely the electronic control module. (Barring any electrical issues with the wiring, etc.) the fan will typically pull or blow air through the coils and over the compressor. This serves to give a bit of compressor cooling at no extra (current draw) cost.
