Disassembly
Electric heaters are hard-wired into household electrical circuits, and like any electrical repair, extreme caution is required. Please, make sure the power is off before working on the heater. You are solely responsible for your own safety.
Remove the two screws at the back on the right side. Slide the electrical box to the right to take it out.
Remove the two screws (one on each side) and disconnect the two connectors (one for the power supply, the other for the motion sensor).
To extract the electronic board, disconnect the screen cable by lifting the lever (LCM1 connector). Unscrew the screw at the bottom.
