No problem on blockages or airflow. I could not get a glow out of the
ignitor at all, so I am guessing a thermostat went bad somewhere, or
the coils, or .... Decided I got my $300 out of it over the last 13
years and not worth the service call and parts. It was making some
squeaking noises too, so I probably needed new bearings too. Ran to
Costco and picked up a $380 Whirlpool that now dries a load faster than
the washer can wash.
