I have a 3978906 whirlpool dryer. Like another has had happened, everything is working fine, No heat. The igniter is lighting, and things are clicking, but no fire. I have little experience with dryers. I have taken it all apart and cleaned the sensors. It lights the first time, every time, I mess with it, but then it quits after the first "cycle" Any ideas? I haven't taken the belt off the motor to test things while operation, but I'm very confused by the fact that there is 120v. to both sides of everything when I check it when it's off.

Either a wire has come loose in the back or on the cord itself or hopefully not the element is burnt out.

Generally, with a gas dryer, there is an ignition device that heats to a specific temperature and this causes the gas to ignite. When this electric ignition fails to work, the gas will not ignite and there will be no heat. I had this happen and had to call a professional. It was a simple matter of installing a new ignition device and it worked perfectly for years. I hope this helps! If it is a new dryer, check to see if this part might be covered under warranty

any of these simple items could be your problem, check it out http://www.partselect.com/dryer+dryer-wont-heat+repair.htm

This happened to me. Turned out it was a gas valve fracture which had to be replaced by the gas company. That's if you have a gas dryer

Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

if you dryer is gas check out this gas no heat tip....

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...

Hi and welcome to FixYa. I am Kelly.

Your power for the burner assy goes on a series circuit from the timer to the high-limit thermostat to the operating thermostat to the thermal fuse to the gas burner assy, thru the motor centrifugal switch to the door switch. EACH of these must be functioning for the burner to light.

This manual will help with some of the how to do it as far as component access, removal and replacement of parts.

Is yours the gas model? If so I need you to look for some things. Open back door panel and see if while trying to light the igniter is glowing orange. Sea Breeze

Solenoids inside the dryer base at gas valves is most likely the problem. Let me know, Sea Breeze

If the electronic start is not working, it may need to be replaced. Call an appliance parts store and ask some specific questions to them about how you can test that component and if they carry a replacement for your specific make and model. Good Luck!

Sorry no pilot light but you have ignite, flame sensor and a gas valve...all control heat...
let me know if I can help
