Customer Question
After presetting temp to...

After presetting temp to minus 20, it just keep running and wont switch off, what could it be and can it be fixed

Contractor's Assistant: I'll do all I can to help. How long have you been dealing with this?

The last triip away in the van and it was for 2 weeks, has been turned off , but we tried it yesterday as we are going away in 3 weeks

Contractor's Assistant: Do you plan on doing the work yourself?

If its possible, our son in law is an electrician

Contractor's Assistant: Anything else we should know to help you best?

No thats about it, we are assuming its the thermostat, its working, but the motor just doesnt turn off

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

We have no idea what you are talking about, sorry

Hello, look for the compressor and condenser coil with a fan behind it at the bottom rear of the refrigerator in most cases... if its not there its at the top... make sure the condenser coil is clean on *both sides (it looks like a small radiator on a car).

We can go from there.

If you need to be coached through a full diagnosis/repair,and wiring etc. for up to two days, and wish to be trained to use test instruments...... that goes well beyond' Just a simple Answer' of course, and goes beyond what most other experts here offer.....rate my answer so far positively.. . and I will deliver that training and coaching to you All on the same dime so to speak.

Lacking a positive rating I can spend days helping a person at my own expense and loose my shirt, shorts and socks on the deal.
