Thank you for that information.
What you may need is a new thermostat. But not necessarily.
The first thing to do, is defrost this one with for 24 hours with the unit unplugs so it can reset the electronics.
Thats may very well cure this issue. But once you do this, it will likley work fine for a week or longer. If the condition returns, please contact me then and I will help you get a new thermostat and help you replace it. This is an easy task if you are just a little handy and have a few basic hand tools;-)
In any case, I will stick with you until this is complete.
