having trouble getting it to heat. last week the dryer would not heat. i took it apart and cleaned out the vent it was clogged. it worked great after that for about a week or so, last night it stopped heating again. i took the fron off, making sure no obstruction in the vent. cleaned everything and now it lights the flame for about 25 to 30 seconds then goes out, then about a minute later will lite again for about 5 seconds then goes out. i have made sure there is nothing clogged, the motor is running fine, it just wont stay lit.
Answer Jeff, If all is clean and clear, and the dryer lint filter was clean, and dryer wasn't overloaded, then you'll need to check for a "weak" hi limit switch 489P3 or a weak set of gas valve coils 279834 . Try this, start the dryer and let it run 15 to 20 minutes, then check to see if the ignition process still occurs, If the coils are weak the igniter will glow, cycle off but there won't be any gas released and there'll be no ignition or flame. If there is ignition but a short burn time, the hi limit switch is weak and cycling the burner off too soon, or there is still a clog in the vent system.
If you have a bad thermostat, will the dryer motor still run, but drum will not spin just like my problem right now?
Answer Burt, Not really, The thermostats control the heat in the dryer drum. There is a heat sensitive thermal fuse in the motor circuit, but if it has failed (opens) the motor won't run, until it is replaced. It sounds more like you may have a broken drum belt 40111201 .
