I have a very old Montgomery Ward side vernt dryer ( model # LNG 7654A22) and it is overheating. When its on for just a second or 2, you can see bright red inside the dryer ( with door open). You can clearly see it is too hot. When the dryer is off, but plugged in, the top of the dryer continues to heat up so I have to keep it unplugged. I am guessing the thermostat is out. On a parts site, I found the parts but I dont know exactly what I need. I am on my own attempting to fix this all on my own, just dont want to pay a lot for a part and it be the wrong one. Listed were: Thermostat-high limit, Thermostat-cycle and Thermal Fuse. Any ideas? I know nothing about dryers!!! I am also trying to do it in a hurry because w/ 3 kids...clothes are piling up fast! LOL Please help!
