I own a GE Profile Dryer Model DPVH880GJMG. The dryer only stays on for about 3 minutes with flame but then the cycle stops. I try to turn dryer on again and stays on for only 6 seconds with no flame. I see no errors. When I am in diagnostic mode the Blower/Exhaust Motor only sometimes turns on when I try to turn it on when in diagnostic mode. Any help much appreciated.
