Dryer. It heats, it dry's and works perectly. The problem is it has this vibrating noise every so often. It just started after 7 years.
So, I bought a Maintenance Kit
and replaced the following:Rear bearing
(the metal ball, plastic cup, little ball bearing and new grease)
New tensioner pulley
and lower felt
All of these were worn out so I felt good putting it back together. It spins great! Heats good. still vibrates, its almost a humming vibration and it will start soft, then get really loud and then stop all of a sudden. Movign the dryer seems to have an effect although I can't seem to get any one particular movement to make a difference. I even leveled it out. I watched the heating element to make sure it s not happening only when heating or not heating and there is no pattern. Help! What could it be?
