I have a Maytag model #mdg8600aww gas dryer. Recently the loads have been taking a long time to dry. So I took off the front panel and noticed that the burner does start up but only runs for about 30 seconds and will shut off for 2 minutes, and then start up again, and run for about 10 seconds. It continually repeats the 10 second on cycle every minute and a half. I have cleaned the dryer inside and out there are no restrictions anywhere. I went as far as taking off the exhaust tube, but that didn't help. I recently changed the moisture monitor sensor, that didn't work. Could it be the high low temperature sensor? If not, does anybody know the answer to this?
