Hi all! This is my first time posting. Nice to meet you all!

Trying to save some money, I purchased a used Kenmore dryer that was in storage for about a year (so they told me). I hooked up the dryer and it seemed to operate fine until I opened the door and smelled gas in the drum. The clothes were dry and felt somewhat warm. Also, it took longer than normal to dry the clothes.

I lifted the top while it was running and noticed the igniter would glow but didn't always ignite the gas. The igniter would cycle a few times and eventually ignite. The times it didn't ignite was when I smelled the gas. From this behavior, it seemed like there was weak gas flow. So, I checked the flex line and all the way up to the gas valve screen to make sure there were no obstructions. Which there weren't.

After reading several post of similar problems, they suggested replacing the gas valve coils. I purchased and replaced the coils but it didn't fix it. 

I replace the igniter not because I suspected it was bad but because I broke it (doh) checking the pipe for obstructions.

The radiant sensor seems to be working because the igniter cycles and I measured it with an ohm meter. When cold, it was closed and when hot, the circuit opened.

Does it sound like a gas valve? They are expensive so I wanted to bounce it off some experts!

Thanks for your help!

If it was in storage without the rubber cap on the Gas Pipe stub, moisture can lead to a rusted Gas Valve.

That, or make sure this dryer isn't setup to run on LP gas instead of Natural gas.

If it has an LP gas oriface in the gas valve it maybe that not enough gas is being let through on the lower pressure natural gas so burner doesn't light correctly.

How can I tell if it's a LP orifice vs. natural gas?

What number is stamped on the brass Orifice inside the Gas Valve ? (remove the Burner Tube)

NG (maybe # 44) 



If it's one of these, other changes must be made also:

Propane  # 54 

Butane  # 55

I checked and it's a #42 orifice.

While out, I checked for any obstructions such as a spider nest and didn't see anything.
