My Maytag washer, purchased in 1990 and model # A8340, stopped working, apparently mid-cycle. I went to check on the load and it had just stopped, full of water. I removed the wet laundry, and it started to refill due to drop in the water level. When I rotate the dial, however, it does absolutely nothing - no sound, no hum, nothing. There are no strange smells like anything has "burned out". I've tried unplugging it and plugging it back in, tripping the breaker, etc. The outlet works fine, as I've tested electric tools on it. Any suggestions on what the problem may be? I'd like to try to repair the washer myself and order the parts on-line.
