Thermostat Problem?

[mcr122]

Summit Kegerator: SBC490-BI. Will not shut off. Just keeps getting colder and colder until total freeze up. Replaced the thermostat twice just in case I had gotten a bad one. (Haier RF-7350-77). Even turned all the way down to lowest setting just keeps freezing up. I have heard that these particular Thermostats require adjustment. #1. do not know how to adjust. #2. seems to me that it should not need adjusting right out of the box.

Anyone ever had this problem and is there anything else I might check?

Moved from Equipment forum to try to get more replies.

Is there a screw on the thermostat itself that could adjust it? Sounds like the stat just isn't shutting it off.

The bright side is it still gets cold so you can put an external controller on it.

With the original and two replacement thermostats malfunctioning, I would look at something else - like probe placement or a pinched wire somewhere between the theromstat and the compressor.

Or just hook it up to an Inkbird temperature controller and call it a day. The Inkbird will shut off power once it hits the target temperature, so it does not matter if the thermostat is running constantly - that is how my fermentor and kegerator are setup. The thermostats are set to max cold and I use the ITC-1000 to set the temperature to within a degree.

I am a proponent for fixing things correctly, but sometimes the easy, cheap, effective way out is the "correct" way. My two cents, anyway, YMMV.
