First of all, I don’t have the model number on Old Frosty (groan). There are several places where some sheets of paper have fallen off the freezer, so I wonder if that was the model number. I’ve looked all over the thing except underneath it (!) The best I can do is a little stamped thing on the side, under the kick plate, that is shown in the image below. I cannot find the “14be 4407” referenced anywhere so I guess it is a serial number and of little help. Old Frosty has a YT relay (it says ‘YT RELAY PATENT PENDING’) with a part number 6580937. The capacitor says “Mallory 7542949 130-156 MFD” (I guess this is a 156 microfarad capacitor??) Again, though, I haven’t found these numbers anywhere and our local parts place also was not able to help.
I want to save Old Frosty for a variety of reasons, mostly convenience (its easier for me to spend a little time here & there working on it rather than taking a lot of time to get a new used one as I don’t have a truck and moving Old Frosty would be a royal pain). For the last 11 years he would sometimes quit working. I have an external thermostat on it as he would lager homebrew for me as well as store kegs & bottles. Sometimes I would notice the light on but no compressor running. A little kick to the front of Old Frosty would start the compressor running again and everyone would be happy. But now kicking is no good.
I know sometimes people can get compressors starting by tapping them with a rubber hammer. However, the compressor is in the back of the unit and the kicking only seemed to do any good near the front, where the relay & dial-switch-thermostat (and capacitor) are. So I am thinking of replacing the YT relay with a 3n1 like in the post “1950's Frigidaire compressor relay”. Does anyone think this is worth trying? Or, would you say the problem is the compressor with 99% certainty?
Or, is there some way I can “override” the relay TEMPORARILY and see if the compressor will start?
Then, my next question: what rating of 3n1 should I get? The freezer is 14 cubic feet, I think (see the other image). My basic horsepower calculation gives a number that seems reasonable (110 volts*4.5 Amps/2) / 750 = 0.32 or 1/3 HP, but I’d like someone’s knowledgeable opinion on this.
And, my final question is more of a comment: the advice in the other post is so close to what I want, I’ve already decided this is a great forum. The whole beer theme makes it even more so. I’ve been homebrewing for over 15 years now although the last few years have been harder to get time for it with children & a wife with some medical issues lately. However I still have the “bug” and its bothering me to no end to not have a working beer fridge.
