The unit keeps running. I have it set at normal and on heat. It is a wall unite a/c heater General Electric "Zoneline" What can I do for it to shut off and come back on. It should cut off when room temp.M Green
Expert:  BillyHvac replied 6 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?
