I turned on my heater last night and the heater light is on saying it is heating, I can feel the heat, but when I try to adjust the heat up or down button it will not allow me because it is locked in at code Ad. Suggestions??

Marlylles it sounds like you could have a bad control board and or membrane pad. If all else fails contact our Service Support Desk to book a Diagnostic and repair of your Maxetherm heater.
