I have a kenmore dryer that will not heat. I opened the front panel and watch the dryer start. the flame stayed on for about 45 seconds. after that it would go out than the ignitor would glow and stop.
I replaced the coils on it and the new coils would not even let it light. Thinking I got a bad set of coils I went to exchange them and these coils start to make a buzzing sound when the ignitor comes on.
I am now at a lost and would greatly appreciate some help.
I am having a similar problem with my Kenmore Elite H3 gas dryer. The dryer starts, element glows, flame ignites, but goes out after 30-40 seconds. If you allow the dryer to run, it will cycle on but go out after 10-15 seconds. After much researching I believed it was the coils as well. After talking to a technician this AM it could be the thermostat. I ordered I set of coils and a thermostat and will see what works when they arrive tomorrow.
Good luck. I will repost and let you know what I find out.
