Thanks Soundguy.
I notice in your pic it looks like both red wires have been cut. Is that what we'll need to do if we add an on/off switch? I like the box. How do I describe that and where do I buy one? Toggle switch I can get anywhere.
With the Thermistor disconnected, the refer seems to be cooling. We'll go out and cut the wire to the Climate Control and let it run all nite. Is that ok to do without a Thermistor (sp?) I bought thermometers and placed one in each compartment. If the refer seems to be working fine, we'll turn it off and order a new Thermistor.
