Title: Thermostat for Ideal55
Post by: BryanH on February 07, 2007, 05:37:19 pm
My slider's t-stat works but... the cut-in and cut-out temps are 10 - 12 degrees and it seems to only cut out at 32 degrees.  I'm wondering if I have the correct t-stat or if I have installed wrong.

- On a slider, does it matter how much of the copper sensor is inside the machine vs coiled outside in the compressor compartment. I only have the last 5 - 6" of the sensor inside.

- I thought t-stats were supposed to have to screws for adjusting the cut-in and cut-out temps.  I could only find a single screw and it was originally covered by red wax (see the pic.  It's by the right hand side terminal).  I haven't played with it yet but I'm assuming this must be the fine tuning on the temp?  Make sense or do you think the screw is for something else?

Try insulating the entire stat, leads, and probe. When they are mounted down below, in the compressor compartment, they tend to pick up the temperature coming off the condenser coil and fan resulting in a "false" reading. That leads to a much lower box temperature. Shove all the extra probe you can inside, insulate the entire stat or mount it inside the cooling compartment near the floor. This should solve your problem.

This t/s has been changed once already. Ideal never
needed that much capillary tube. Also, the end should be
coiled so it can be slid up into the sleeve  and have more cold
contact surface.  Try coiling the end of the tube around
the shaft of a thin screwdriver about 10 times before
re-installing.

Glen - the capillary tube has been bent so many times that coiling it was not possible.  Could I cut the end off and coil the cleaner / straighter part?

I don't think so..........the cap tube is full of gas.
