Hi-
The other day, I picked up a free Kenmore chest freezer (6 cubic ft) through Craigslist. The guy told me it worked...well, it doesn't. Anyhow, it appears to be pretty old (model 10068, can't find it listed online). I had it plugged in overnight and it didn't get cold. After reading some troubleshooting FAQs online today, I tested the starter relay and found it to be defective.
Is it worth buying a new relay for this freezer (which didn't cost me anything but gas)? I see that one of those Supco 3N'1 relays is cheaper than the original starter relay piece (MM5-46S). Or should I just dispose of this thing? In case it's relevant, I plan to use this with an external temperature controller to keep it in the mid-60s for fermenting homebrewed ales.
Thanks for any input.

If you have an amprobe, measure the run current of the compressor. If not, I would NEVER use a 3n1 start device!
If the overload is ok, I would install a GE start device, a plug in, WR07X1055, rather cheap.
If the unit has a run capacitor, you must wire that in parrallel across the start device terminals.

Thanks. I don't have an amprobe (just a multimeter -- I don't have much experience with major appliance repair). I googled that GE part number that you mentioned (WR07X1055) but there were no hits.

Sorry, misstake in part #, should be (WR07X10055) or AP3772916, on this site, about $9.00.
Also, when you install it, the black tab must go on top of the common pin, actually, the only way you can install it.

Oh ok, thanks. Can I measure the run current with a multimeter? Also, I forgot to mention, the compressor felt hot to the touch after the unit had been plugged in for hours. Is this normal?

A hot compressor is from current but no run condition. Make sure you wire in the overload device, proably a round item that plugs into the common compressor pin, usually on top. You need an amprobe to measure current.

Sorry, I made a misstake on the start device, should be WR07X10051 This device is good up to 1/2 hp compressors. Yours is probably less than that.
