Ref: 13 Year old Maytag Electric dryer……
My dryer has just started making a noise / rumble only during
start-up…. The noise go’s
away one the dryer comes up to operating RPM’s…..
— The belt, Tension pulley, or wheels have never been changed…..
Can you advise what maybe causing this noise on startup ? I can then
order the parts.
Ah yes, the mysterious rumbling dryer. The cause of this noise has eluded many do-it-yourselfers. But St. Applianopoulos, the patron saint of appliance repair, has led you here to the Oracle of Appliance Enlightenment® for further illumination. The problem is not the belt, idler pulley, or drum rollers. It’s the blower wheel, shown here to the right–click the picture for larger view.
What happens is that the hub of this plastic blower wheel eventually wallows out on the metal shaft and no longer makes a tight fit. That’s why you hear it rumbling when the motor shaft starts spinning the wheel from a dead stop. Once the blower wheel is spinning at the same speed as the motor shaft, the noise goes away. Likewise, when the motor stops, the blower wheel’s momentum causes it to again spin at a different speed than the shaft and the noise reoccurs. Replacing this blower is an easy repair, not even two mugs on the SUDS-o-meter.
To make this repair, you’ll first need to disassemble the dryer to get access to the blower wheel. To remove the old blower wheel and secure the new one in place, you’ll need a pair of external snap-ring pliers. If someone else reading this has a Magic Chef dryer, same deal applies. You’ll need to order a slightly different blower wheel, shown here to the left.
That’s about all there is to this bit of rocket science. Now go fix your dryer!
