Blower Belt

First diagnose the problem. No air coming out the exhaust or filter, things aren’t drying, you can’t hear the blower running.
Fuses or breakers are verified ok and on.
Turn dryer off. Disconnect exhaust tubing after unscrewing it’s clamp. Drag the dryer away from the wall to get access to the back and unplug the 220 v power cable from its socket. Get behind the dryer to remove its back cover plate by unscrewing its holding screws with screwdriver or small socket wrenches.
Vacuum out the back of the dryer removing the powdery dust around the blower motor and pulley and remove the old belt.
Since there is no adjustment arm, you have to stretch the belt around the rim of the blower pulley with both thumbs pulling upward against the motor pulley below.
After the belt is in place you can pull on it to be sure both pulleys rotate so the blower fan will rotate. Then just put the back plate on the dryer, replug it in, push it back enough to hook up the exhaust pipe and push the dryer back to its home spot.
Turn it on and you’re ready to go. Then order a spare belt for the future in about 5 + years.

Called my son. He took off the back put the belt on and we were ready to go.
