I have a Kelvinator dryer model dea/dga501k. It's doing a lot of squeaking. What can I do to stop it?

It needs a new set of rollers for the drum I can bet. If your able to do appliance repairs this wouldn't be to hard. The hardest part would be putting the belt back on most likely. I would think you should be able to find the build up of your machine on the web here and use it as an instruction manual. Good luck to you though.
