Speaking of clogged vents...
When I bought this house I had my hands more than full with tending to the floor refinishing, wall painting, garden/landscaping, plumbing, cooktop, gas connection, etc.
Well.... I replaced the '78 matching GE filterflo electric dryer with a WCI gas model that I'd had in the previous residence (rental house). I was not happy with the performance, and it seemed to get slower and slower in drying, and the cabinet seemed to be getting way too warm.
Finally I replaced it with a Neptune 7500 set, and the first thing the more powerful Maytag blower did was blow a big lint clot out the vent. I think I narrowly missed said dryer/lint fires, as well. Thanks to the Neptune's more powerful blower, it hasn't been an issue since, and I check it ever few years. I also have a louvered vent draft arrestor, so I can tell at a glance (the vent exhaust opening is right by the back porch) if the vent is getting clogged or not. If the louvers are horizontal, there's plenty of air flow.
Unfortunately in all of this I donated the matching GE filterflo electric dryer to charity. Of course I wish I had kept it now, but at the time I had no idea it might be of interest. Still have the Harvest Filterflo washer, though.
