Propane dryer, intermittent smell of propane. no leaks on the back side. Gas valve leak or not seating completely?
Answer Dj, Under the circumstances ( LP Gas Conversion) the issue would be in the gas valve itself, a sticky plunger or pin hole in the diaphragm.
However, our research shows a different part number for the gas valve, than the one you provided [AP2043472} our research shows WE14M132 as the gas valve needed for your dryer. You may want to recheck the parts diagram before you order parts. And don't forget, you'll need to transfer the LP Parts from the original gas valve to the new gas valve.
