Removing and Replacing
the Original (White) User Interface
Please check the troubleshooting instructions in Section A before replacing the user
interface. Here is the removal/ replacement procedure:
1. Turn off all power to the NeoTherm unit, and shut off all manual gas valves.
2. Remove the front door on the NeoTherm, and remove the plastic bezel from the
control panel.
3. Disconnect all of the wiring connections to the control module. (The connectors
are keyed so that they can only be inserted one way. Be careful not to bend the
wires sharply or pull them out of the connectors.)
4. To remove the user interface, push in on the two tabs on the left side of the board
to unlatch the clips from the control panel. Rotate the board around the fastening
points on the right side to separate the hooks from the board.
5. To replace the part, repeat the steps listed above in the reverse order. Be sure to
re-connect all of the wiring connectors in their proper locations.
