How do I replace the ON/OFF switch on a Suburban water heater?

Disconnect 12V power at the battery before starting. Remove the interior switch plate, unplug the wire harness from the back of the old switch, and transfer the leads to the new switch in the same orientation. Reinstall the plate, restore power, and test ignition. The job typically takes 15 to 20 minutes with a Phillips screwdriver. If your water heater also needs winter service, our RV winterizing kits cover the rest of the system.
