Some filter material got into the return line and was sucked into the unit, it was smelling a little like burned plastic, probably piece of filter. The unit was also coming on and off about 3 times during each cycle. I pulled the filter out,(it looked whole, and not chewed up), but the on and off still happens.
The air cools great and the thermostat is ok, I put new batteries in it also.
Any idea what is causing the on and off?
Thanks
