Gas smell

Hello everyone new to the Forum

I have a maytag dryer that just today started emitting a gas like odour
The dryer seems to operate normal except for the odour which also seems to be in the clothes as well…

I have checked the vent and as well as run the dryer off the vent hose just to see if it made any difference… doesn’t seem to…

I removed the frt of the dryer and ran the dryer I can smell the odour while my head is at the frt of the drum or slightly inside the drum…lol

Any idea on this …Thanks for any help…Chris
