Kenmore Dehumidifer fan free but stops

[SIZE=2]I have a 3 week old Kenmore dehumidifier model 580.54701. with electronic control. It is a 70 pint low temp. It runs O.K. and pulls out alot of water but after a while the fan stops but the compressor keeps on running. The fan is free cause it takes a while to coast to a stop. To remedy this I stop it via the power button and immediately restart it and the fan starts and after the freon pressure drops the compressor restarts also (Auto restart). Sometimes it will go a few days without a problem and then it will do this twice in a day. I think its the circuit board but want advise.
