The dryer heats for approx 3 min and then the high limit cuts out for about 2 min. It continues this cycle. I replaced the high limit switch suspecting that it was cutting out improperly but no change in operation. The element is in good shape as has not grounded out to the frame. I have now removed the thermostat hoping that is the problem. Tested it on a frying pan and it got very hot before it opened, but it did open? There was also a smaller nickel sized contact which face the back of the machine? Can you offer any other clues?
ANSWER Jesse, The smaller nickel sized thermostat should be the "thermal limiter" It is a "one shot" thermostat, if it "opens" it doesn't reset, and the dryer won't operate until it is repalced. If the hi limit thermostat is opening, and you've replaced it, your first check needs to be an air flow issue, Have you checked the exhaust vent pipes and vent hood for clogs, restrictions and kinks ? You'll also want to check the lint filter, blower housing, and blower wheel for lint, restrictions and air leaks. You may also have a "sticky" control thermostat, nort opening at the preset temperature(145-155 dgrs.) and allowing the dryer to heat to the hi limit temperature.
