Product review (5 stars): What the Dryer Doctor ordered
I installed in 10 minutes.  Easy. I already had the dryer taken apart.  Put cabinet back together started the dryer the flame ignited.  Dryer now works like a champ.

No word on long term reliability of these parts, as only time will tell.  Less expensive than the Clinic where Repairs are done, if you catch my drift.

I was able to rule out the high limit and cycling thermostats, the timer, and the ignitor using basic troubleshooting.

These are likely the first parts you should order if your gas dryer spins, but clothes don't dry.  Watch a few videos for your model dryer and then DIY!
