The dryer heats but has a loud noise sort of like a shoe in the dryer. We don’t know much anything about dryers but thought we’d take a look and see what was to be seen. Took off the back panel, used vac on dust/lint and metal shavings dust particles 
Don’t know what is causing the noise or metal shavings. Any suggestions on what it sounds like it could be? Oh, how do ya get the front panel off? 
you’re gonna need some new rollers Unplug it remove the screws under lint screen grab hold of top in back just under control panel and pull forward that will release the top from the clips in front flop the top back and let it rest against wall. inside front panel are two 5/16 hex screws reomove those lift front up and off clips release belt from idler paying attention how it is looped for reassembly leave belt on drum grab a hold of belt from top of drum and using belt as a handle remove it in the rear bulkhead assy is your rollers dont remove the shaft from bulkhead just the clip in the groove and on left side you have to remove push nut and screw going into bottom of machine replace both rollers and the belt since its torn down reassemble in reverse order
