I am trying to replace the rubber plunger below the center On/Off control. In order to do this, the plate needs to be removed, and in order to remove it, the 2 air control knobs have to be removed. Simple, eh?
Problem is the knobs won't pull off. There are designed to just pull off. Apparently some corrosion/mineral action is going on. I've tried pulling on them with a pliers.
The supplier doesn't have a good idea, short of spraying with WD-40. Makes no sense to me since it just drips in around the knob, but won't to, and up, the center stem. But, hey, I tried it anyway. After a couple of hours the knobs still didn't pull off.
Anyone have an idea of how to deal with this? Hot air gun on knob, hoping I don't melt anything?
