My Repair & Advice
Cleaned out all the vent pipes and inner dryer air flow paths of lint. Replaced both the hi temp thermostat and both gas valve coils to finally get it to work correctly. I replaced the cycling thermostat and flame sensor also, but this apparently was not the problem. Dryer hasn't worked this well in several years, so coils may have been degrading much earlier. It is like having a new dryer.
I bypassed the hi-temp thermostat initially, and the dryer heated up correctly for a few minutes,
then stayed cool. This indicated the coils were failing when heated. I replaced the coils, then
tested with the front cover removed as there is no inspection port on my old dryer model.
The new coils did not fix it with the front panel removed. After trying several other things, I
decided to try the new coils again, but put the front panel back on before cycling, and it worked.
I have no idea why new coils did not work the first time, unless I had a poor connection.
The air fluff only, no heat cycle should advance the timer as no heat is required in this cycle.
The advice on AppliancePartsPro.com site was essential and gave me confidence that I could
fix it eventually. Thanks to AppliancePartsPro.com for a great experience.
