Electric hot water switch on 2001 expedition
If someone out there has a 01 expedition and could please tell me where the on/off 12 volt switch is located for the electrical side of the water heater I would be grateful. I know the one for the gas side is located over the driver Sun visor. And I know about the two 110 v ones near the sink but were is the 12 v one that brings power to the board. Iam lost
Or a brief description of how your water heater works would help
Thanks
Richard

Sorry , but I have to ask again , 12 volt switch ? Everything I could find makes no mention of a switch but rather a fuse.

It is very rare to switch the 12v power to the heater circuit board, but it is always protected by a fuse. I don't know where the "house' 12v fuses are on a 2001 Expedition, though. They are usually togrther in one lace. however.
How it works: the circuit board must always have 12v power in order to work, but basically that handles gas igniton and gas supply. The circuit board turns on/off the gas supply and operates the igniter in response to the thermostat demand. In electric mode, the heat is supplied via a 1400 watt electric heating element and the thermostat controls when the 120v power is applied to the element. The heater can operate in gas-only mode, electric-only mode, or gas and electric simultaneously. There are differences in the details depending on ear and model of heater, but that's the basics for an gas/electric heater with electronic ignition. Pilot and pilot re-light models are somewhat different, but you don't have that type in your Expedition.

The 12 volt switch is the one above the pass visor. I haven't found any others and mine works with gas turning on this switch. You may have a 12v feed problem?
