Read up on what to do when experiencing no heat in a gas dryer. I took the front cover off and unplugged the dryer from the outlet. I then unplugged each sensor one at a time and checked the following items for continuity- Thermal Fuse, Cycling Thermostat, Ignitor, Flame Sensor and Gas Valve. In the diagram, I couldn't locate an actual "cycling thermostat" so I assumed the Hi limit thermostat was the same thing, which I did test. All items pegged my meter at just about 0 Ohms. The Gas Valve ranged between 1.5 and 1 Ohms. The dryer spins and everything seems to work with the exception of absolutely no heat. I don't see the ignitor heating up at all and do not hear any sensors clicking. Any suggestions would be hugely appreciated. Bob

I forgot to mention that I also checked the vent and the entire dryer for any lint related issues that may be causing my problem. The vent is completely clear and venting properly. In addition, I vacuumed the entire Dryer unit, lint trap and vent tube just to be certain. I still have no Heat and no Clue! Bob

Bob Well, if you checked all of those things, then it must be a bad ignitor. Tom ApplianceEducator.com

Hi Tom, you would still think it is a bad ignitor despite that it had passed the Ohm test or the Ohm test is not a good test for the ignitor? One last question- Can the Thermal Fuse, Flame sensor & Cycling Thermostat be jumped out one at a time, as a safe way of diagnosing the integrity of those parts? Thanks very much for your reply. Bob

Yes, I would jump out the sensor first, then the t'stat and then the thermal fuse. If the ignitor does not come on after that the ignitor is bad. Whatever part jumped out, makes the ignitor come is the bad part. Tom. ApplianceEducator.com

Okay Tom, as instructed one at a time, I had jumped the Flame sensor first, then the Thermostat and then the thermal fuse, and still the Ignitor has failed to glow. I am going to take your advice and order up a new Ignitor and see what happens. I will keep you posted. Thanks for all your help. Bob.

Hi Tom, The Ignitor arrived today and I installed however the ignitor is still not lighting up and therefore there is still no heat being produced. I re-checked each of the sensors by jumping them out one at a time, but still the ignitor will not glow. I am definitely baffled...any ideas? thanks, Bob

Unknown to me, there is an item called a (Thermostat, hi - limit) which is #38, and an item called (Hi limit t - stat) which is number 22. I was jumping #38 and getting no results. When I realized the name of Part #22 being similar I decided to jump it, and the ignitor lit right up. I feel stupid but let this be a lesson to everyone out there. The hi limit t-stat is different from a hi-limit thermostat. Tom, thanks for all your help! Due to my own stupidity I purchased a part that I didn't need but am still way ahead in the savings department after purchasing the part that I do need.
Best regards and thanks again, Bob
