Thanks this is first time to try to use such a site as this.

Sounds like the defrost timer switch went bad. Happens all the time on side by side models regardless of what brand. I had a huge side by side in South Florida that would eat defrost timer switches at the rate of one a year. If your model is an older one and does not have a circuit board but for real parts that can be replaced, just go to an appliance parts store with your model # and they will hook you up with a new defrost timer switch. If you have a multitester, use that to determine if the switch is bad.
