I hope these guys can help you. We've used them a couple times when our gas dryer required service. If they can't fix it, maybe they can refer you somewhere.....
I have their business card in front of me but there's no address listed. I'm including everything on the card below:

The guy that's worked on our dryer was Dean Bolek. He's a really nice guy and very efficient. He won't remember us from Adam since we have only required two service calls in 14 years of ownership and there were spaced far apart!
