I have a dryer that will heat up and it sounds normal for about the first minute. Then it sounds much different with a loud buzzing sounds. I have replaced the heating element as well as the motor. What else could be the problem?
Answer Bruce, It could be an expansion rattle, from the heater or the heater duct, and check to make sure there aren't any kinks or clogs in the venting or vent hood. Then check the blower wheel 56000, make sure it is fitting tightly on the motor shaft.
