The dryer works fine for 15 seconds then the burner goes out. After about 1 minute it relights and burns for 15 seconds then burner goes out. I tryed trouble shooting by bypassing the high temp thermostat. After doing this, the burner remained lit. Thinking this was the problem I replaced the high temp thermostat. (Since I was doing this I also replaced the low temp thermostat) After replacement I ran the dryer only to see that it ran as it did before for 15 second cycles. I again bypassed the high temp thermostat and the dryer again worked fine. I reconnected the new thermostat, it again went back to 15 second cycles. Any suggestions?
