We have a Maytag top loader that's getting on in years. Recently, during the agitation cycle, it would make a funny noise and the laundry room would fill with smoke. Figured it was the belts, so I changed those. Very easy to access without having to remove panels. Just need to tip the machine back. That worked for about six weeks, now we're back to the noise and smoke. Anything else I can look for that might be causing this problem without calling in appliance repair? Again, only happens during agitation. Could be that we're filling the machine too much causing too much friction for the thingy to go back and forth. I'm going to try a half load later to see if that works.
