Whirlpool gas dryer wont heat.

Whirlpool gas dryer wont light. Blower and drum work fine. How do I determine if it is the igniter or if it something else?

Here is what I would do first. Unplug the dryer, and take the back off. Once the back is off, you will see a small thin, white part. It will be an inch and a half long, by a half inch wide, and will be held in by one screw, and have 2 wires coming to it. Take the 2 wires off, and put the terminal ends of the wires together, and put some tape around them to keep them together, and to be sure they don’t hit metal, and then plug the dryer in and see if it works. If so, DO NOT !!! Run the dryer that way. That is a saftey. This is for diagnostics only. If it does not work, let me know. If it does worklet me know. Tom http://www.applianceeducator.com

I checked continuity in the fuse it’s good. No flame

jump out the flame sensor on the left side of the flame tube, and see if the ignitor comes on. If not, replace the ignitor. Tom. http://Www.applianceeducator.com

where is the igniter located?

I have removed the ignitor and ordered a new one this morning. Should I check resistance, if what should it read.There is contiunuity through the radiant sensor. I presume its normally closed.

You know Ray, sometimes on some conponents, taking a resistance is not totally accurate. That is why on those gas conponents, I always jump them out. Then you know for sure. It sounds like you have it. Let me know. Tom

I got the new ignitor today and installed it. Still no flame. What now? Check the coils or replace them? What else can it be?

Ray, you have to do this my way, so we can get you a dryer. If the ignitor comes on and there is no gas, it is most likely the coils, or possibly the whole gas valve. If the ignitor does not come on, then do it this way. We are going to systematically jump out each conponent till the gas comes out. Now unplug the dryer, and take the 2 wires off of the thermal fuse (The little white one in the back) Put the two terminal ends together, and put some tape around it, so it does not hit metal, and keeps the terminal ends together, plug it in, and see if it works. If so, replace the thermal fuse. If not, unplug the dryer, and put the wires back on the thermal fuse, and then go inside, and do the same thing to the the flame sensor. Then plug it back in, and If it works replace the flame sensor, if not, then the coils on the gas valve, or the whole gas valve is the issue. Do it this way. Also, tell me if the ignitor comes on.

I have jumped out all components to the except the coils. Ignitor comes on momentarily but the gas does not flow. How do I determine if it is the coils or the valve itself?

If you ohm out the coils, they will check out good. But, they might not be. Ray, her is what I do. I would put the coils on, because they are alot cheaper, and it takes care of the problem 90 % of the time. If not, a gas valve it is. Let me know how it goes. Tom

first look to see if the ignitor comes on then goes off without any flame – if so probably bad gas valve coils if the ignitor doesnt come on then the ignitor is bad or the thermal fuse and / or operating thermostat is bad or multiple other less common problems (timer, motor switch, broken/loose wire, etc)

Kind of a pain but it’s done. I replaced the coils and it’s back on line. Thanks Tom.
