A few weeks ago the wife said the dryer would no longer work in the Automatic Dry mode so she was using Timed Dry. Now even in Timed Dry it is taking a long time to dry a load. Sometimes we open it and there is no heat at all.
One year ago I replaced the thermal fuse, cleaned out the vent tube inside the dryer, and put a new vent line in. Just checked that, it was all pretty good.
Research shows it could be the Cycling Thermostat or the Valve Coils. They are pretty cheap, should I just replace those, or are there any steps I should take first to rule out something else?
Thanks as always.
