From your previous question: the Replace HEPA filter light wont go off.

Check to see if there is a crack in the ceramic plate. If there is any type of disturbance where the metal is glued to it or you don’t have both leads on the metal it will not work

There is undoubtably a safety switch that is not properly closed.
A door, a panel, or a latch that is not properly seated and closing the safety switch is probably the cause.
