I’ve had this 12cf fridge on my boat for maybe 15 years – perfect fit, low amperage draw, works great except…a fan has become (sometimes) very noisy and (for at least several years) I have been having water accumulate in the bottom of the fridge cavity. Are they related?
Yesterday I pulled it out, took off the lower back panel, and took the pictures below.
Issue 1) on startup, sometimes, a fan is very squeely, noisy, like it’s trying to spin up…binding…trying…goes for a few minutes…then it’s running OK and I don’t notice again. Except it might do it for a few days. And then maybe a few days it doesn’t. This noise issue has been going on for several years, but since I only notice it when sleeping onboard in the summer I forget about it, but now I’ve decided to try to fix it.
Issue 2) It’s been a number of years…cannot recall if it coincides with issue #1, but there is (apparently) no water condensing into the tray – it all accumulates in the box. I’ve been using a large sponge there and it seems to keep up – a few days to sopping with frequent use, as much as two weeks in the winter when not in use and the ambient temp is lower (like in the 50s).
So I took off the cover, adjust it power on, and…no significant noise. But I have to think it’s coming from the fan that’s running inside the large coil. The compressor is quiet, I think there are a couple of small fans in the freezer and fridge compartments that run when the boxes are opened, I suspect to help suck in the doors when closed. I don’t think the noise if from those fans. Which really leaves the fan inside the coil. Is this replaceable? I’m pretty sure I can pop the blade off and extract the motor and shaft without having to bend/break any of the copper tubing. Of course I could also hit it with a lube, but my gut feel is the noise it will come back rather soon.
And I cannot see where the condensate should be coming from. There’s the tube coming down into the pan, I can probably take the rest of the back off and I’m guessing that it’s coming from one of those fan units at the back of the fridge or freezer. There isn’t any hole I can see like a drain at the bottom of the box (which would obviously be too low a pickup point to make it to that tube anyway).
Question 1: Am I probably right that this fan is the source of the noise? Should I try to remove it and source a new one?
Question 2: Where should I look for the pickup point for the condensate drain?
Any guidance appreciated.
