One of the two panels that cover the blower motor compartment has started to rattle. There is a switch on the lower part of the compartment that would put tension on the unsecured side of the panel to prevent rattling. I am wondering if something is wrong with the switch and do I need to replace it.
The switch is an power cut off for the furnace if a child gets into the bottom section. You may bend either the switch or the lip on the door to stop the noise.
