system cycles off/on

2 days ago I wrote about the unit cycling off/on at random times. After the tech left with no answers I looked myself and discovered debris in the cooling vents on the rear end of the motor. I removed the debris and the unit is functioning fine now. Apparently the debris was blocking the cooling air enough to cause the motor thermal protection to shut the unit down.
