The dryer is 6 years old. When it is running there is a load bearing squeal seeming to come from the rear of the dryer. Is it the motor pulley? Easy repair? Cost? Worth repairing?
The common noise makers in a dryer are the tumbler support rollers. You’ll get anything from a squeel to a rumbling noise. Then there’s the idler wheel (belt tensioner, of a sort). It gives a higher-pitched screech. If you replace the rollers, it’s also not a bad idea to replace the idler (they’re not too expensive).
Thanks. The idler isn"t a wheel but a teflon semi circle so I wouldn"t think that would squeel. Although it is worn. The tumbler wheels seem okay. Does applying graphite solve the squeeling where the wheels ride on the shafts or do you have to replace the wheels?
If the rollers seem to be i good shape; the centers aren’t out of round; and the shafts don’t show any wear, clean them off and apply some lubrication. Given the naturally humid conditions of a dryer, I would use something like Triflow (teflon-based lubricant), or a silicon-based lubricant. Graphite will quickly gum up and make things worse.
