Prior to 2004 Atwood used separate set of t-stats for electric and for propane. Electric set was on backside with element
Electric was direct 120V AC and propane used 12V DC to a small circuit board.
In 2004 they used a DC circuit board to operate/control electric and propane. Allowed for just one set of t-stats in outside compartment.
Under the cover for element is a 'relay'.. DC power that allows 120V AC power to element.
