Estate gas dryer heating at first, then no heat.
Model Number: tgds840pq0 Brand:
5 - 10 years
At the beginning of the dry cycle, the dryer has heat. Then, 10 min or so into the cycle, the heat stops and the dryer keeps going. I see the igniter glowing, but no flame comes. I've tested all the sensors in the rear of the machine (thermal fuse-on the vent housing/exit side of drum near the fan, and two thermal fuse cut out sensors?-on the heat housing/prior to entering the drum) and all have continuity. there is one sensor that is next to the thermal fuse (next to blower fan) that has 4 wires connected to it that I have not tested...not sure how. I haven't checked gas valve solenoids or anything that requires tearing the whole machine apart yet...
I've seen a lot of questions about no heat, but can't find any about my specific situation. The closest I have come is info telling me that I may need to replace the coils (same as gas valve solenoids?) and that they can't necessarily be tested.
any advice, or do I need to post more information?
thanks in advance!
