Domectic Duo Therm Penguin not operating properly?

I will have to look at the schematic, as doing some testing for the last couple of days the unit definately shuts off when it reaches temp and then turns back on. I think I also have a bearing going out in the motor so I will need to see how difficult that is to get out of there and replace. It will get a work out this weekend though as we are loaded and headed to Calistoga, CA for our Anniversary! Looking forward to getting away.
