The flame on my dryer would go out after several minutes and would not come back on. When looking through the sight hole at the bottom left of the front panel, I could see the igniter glowing orange, but the flame would not relight. I replaced the gas valve coils, flame sensor and dryer cycling thermostat. This was the first time I ever attempted to repair a dryer and I had no knowledge of the process. Using the help videos on this website, I was able to troubleshoot the problem and replace the suspected parts. Replacing the parts took about an hour to do. My dryer is working perfectly now and I saved hundreds over the cost of a new one…Thanks AppliancePartsPros.com!
