Expert:  BillyHvac replied 10 months ago.

You have what is called a stuck "sequencer". This switch can fail and actually weld the contacts in place so nothing ever shuts off.

This is a 220v switch so I only recommend replacing yourself if well versed in electrical.

Is this something you are going to do yourself?
