Gas Dryer Wont Heat, Smells of LP gas.

Noticed this morning that there was a strong LP gas smell outside my house, and I managed to trace it to the Dryer Exhaust vent in my backyard.

Went inside and opened the dryer and took a big whiff, and sure enough, it was coming from there…

Ive googled for hours, and only thing that comes up is people saying that the Dryer wont heat, but leaking gas??

Gas doesnt leak while the dryer is off, and didnt seem to leak while it was on the high heat cycle, but once the dryer switched to low heat, you could smell it again.

Any ideas? Im a pretty handy guy, but this one stumps me.

Thanks in advanced for your help!!
