Ranco Temperature Controller Failure

[aredling]

Has anyone had one of these fail on them?

I purchased a chest freezer about 5 years ago that already had the conversion done using the Ranco ETC111.

I had no problems with this in the past 5 years and all of a sudden (well in the last 2 months) the unit failed. I didn't notice this as I haven't drank any homebrew from the keezer in 2 months. Went to open the thing last week and it was pretty nasty in there.

Setting on the Ranco was for 38, but the probe read 52. I removed all the beer, unplugged the freezer from Ranco and into the wall and the compressor kicked on within a minute.

When I have the freezer plugged into the Ranco the light is on the freezer but the compressor doesn't kick on.

Any ideas?

Check to be sure the wires connections are tight. I had the common come loose in one of mine.

I've had one ranco go bad Acted like it was the memory. It would work a few degrees above and below a certain range but gave an error when set to mid 30s to 40 F

Yeah, i opened it up last night and re-set all of the terminals.

I'm thinking it's toast.

Unfortunately the wrong thing is toast.

Looks the keezer is on it's way out.

Been plugged into the wall for 24 hours and is still parked at 48 F. I guess it's going to turn into a fermentation chamber now.
