non contact thermostat issues ideal55

[jtoenges]

Just replaced my old thermostat with a non contact type for an ideal 55.  I drilled a hole in the tub where the rack is located and placed the wire thru the hole about 1/2".  The compressor has not turned off yet (8hrs).  I have it at the warmest temp.  If I turn off the thermostat the compressor turns off so I am pretty sure the thermostat is plug in correctly.  I have the thermostat bolted to the same location as the original.

What to do?

Try mounting the entire thermostat in the cabinet. I usually mount a bracket under the middle shelf.
That way, the entire unit is in the same climate.

It may be a location issue (as stated above) or you may not have enough of the capillary sensing tubing exposed inside the machine, the thermostat will "see" the temperature along the entire length of the capillary tube, so by leaving the majority of it outside the bottle compartment it may never get cold enough to turn off the compressor.

a quick check to see if the thermostat is still working and not damaged or defective, turn your control to its coldest setting, then get yourself a can of computer keyboard "dust off" or any other brand of "canned air" & tip the can upside down & spray the end of your sensor tube with the liquid freon that will come out of the can ( watch your fingers. it's about -40 degrees-F ) it should turn off the compressor...good luck

       A non contact thermostat is designed so it reacts to cold air blowing across the majority of the capillary tube.
      As stated your tubing is only 1/2" exposed, but more importantly.......... a slider does not have a fan to blow air over it.
      You didn't state why you are using a different T/S, or why you chose to route the cap tube to inside the liner rather than up the cabinet liner tubing as original so you may need to add more info.
      Incidently, to coil up a cap tube, wrap it tightly around the shaft of a small #2 screwdriver and it will fit snugly into it's proper location.
