After I researched the problem and determined that there was a problem with the timer dial switch on my Kitchen Aid Superba gas dryer, then I had to figure out where to get the part. I found several sources on the internet, but I decided to get the part from AppliancePartsPros becasue of two things. The site let me check the correct part with the serial number of my dryer and secondly, I would be able to return it if it was not the right part.
They shipped it out that day, and I had it within 2 days, and put the part in the next day. Works perfectly. It was the actual Whirlpool part not some knock-off. Problem solved. Dryer is running, starting and stopping as it should.
