I have an Amana LEA30AW

Question

I have an Amana LEA30AW that is approximately 7 years old. It takes 2-3 cycles to dry. I have checked the voltage at the plug 240VAC L1-L2 and 120VAC L1 or L2 to Gnd. I cleaned the lint from the vent duct and the inside of the dryer. There was minimal lint. I drilled a small hole (5/32?) in duct at the back of the dryer and inserted a thermometer. The discharge temp with the cloths almost dry is approximately 165? F. There appears to be a good air discharge at the wall vent. Any ideas would be appreciated.
