Expert Reply:
The Fogatti RV Tankless Water Heater # LSB64FR has a switch located inside the unit to the left of the exhaust vent. If this switch is off the unit will not operate. There's also a fuse right below it that you'll want to check before turning the unit on.
If the fuse is fine and the switch is on and the unit still isn't powering on then you'll need to test the power wire at the unit with a multimeter # PT89ZR to see if maybe you're not getting a full 12v to the unit. If you're getting less than 12v then either your power source (battery) is the issue or you're experiencing voltage drop and will need to increase the wire gauge running between the two.
You'll also want to check your ground wire and ensure that it's running to bare metal (preferably the chassis) and is secure.
If you've checked all this and still can't get it to turn on then let me know and we can keep troubleshooting.

I’m having trouble with my hot water heater. I have 12v/gas/water. I have no power to the controller when wired up. I have wired up two blue wires to the controller, black to positive and white to neutral. Ground wire I have on a screw on the backside of the frame. Any ideas?
