“Of course, for a gas dryer it’s got the typical yellow haze on the inside drum and look at the soot and discoloration around the warm air intake. Dear lord that’s horrible. How anyone ever thought drying clothes in LP/NG exhaust air was at all acceptable”.
I politely beg to differ, the drum on my Maytag DG306 (soon to be DG407) doesn’t show any sort of signs yellowing, even have the original drum in the room next to me and don’t even see ANY sort of evidence of yellowing. Only thing that was yellowed were the felt seal that prevents items from falling into the shroud (this happens to Maytag electric HOH dryers, too), the larger outer felt seal as well, and last but not least is the door gasket which looks to be yellowed from heat, same goes for the electric Maytag HOH dryers too since they have the door gasket on them yellow/discolor after many years of service.
Yellowing drums and soot around the air inlet aren’t only on Whirlpool built 29” gas dryers, the electric 29” dryers tend to have soot deposits on the air inlet grille and tend to have yellow drums after many years of service and I can concur since the drum on lot 1963 Whirlpool dryer is yellowed after many years of service.
I will say if dryer drums and the bulkhead were still all porcelain, there wouldn’t be any issues with yellowing on either gas or electric dryers.
