Hi my name is Robert.....

To start on this go to the outside access panel and tell me if you see a sticker on it with a make and model number, it should be an Atwood or Suburban but need the model number. Follow ups are included.... Robert

OK

When you go to start the water heater with the switch do you hear anything at all, it should be trying to spark. You can leave the cover down and see if it sparks at all when the switch is turned on.....

I DONT SEE ANY SPARK
Expert:  Robert replied 6 months ago.

OK

Under that outside access panel you should have a circuit board, if the circuit board has a fuse on it make sure it is not blown, pull the connector on the circuit board and clean the contacts with a pencil eraser, sometimes this connection point can be a weak link. Look for a brown wire coming off the circuit board and tell me if you see a clear plastic shield over part of the brown wire. Robert

WHEN I UNPLUGGED THE FUSE AND PLUGGED IT BACK IN. IT CLICKED NOT AS LOUD OR AS LONG AS WHEN
IT LIGHTS. JUST WHAT I WOULD CALL THE PRECURSER TO IT NORMALLY IGNITING. I DIDNT SEE A CLEAR PLASTIE SHIELD

OK

Pull the connector on the board and clean the contacts on the board with a pencil eraser, if it still will not light off I would have a RV shop test the board, most RV shops have a special board tester and can tell if the board is bad or not. I can give you a service manual as well that would explain the operation, if the switch is ON and it is not firing off then I suspect the connection may need to be cleaned up or the board is at fault...

OK THA KS IT WONT LIGHT
Expert:  Robert replied 6 months ago.

OK

SO you say it wont light, if it still is not sparking I would have the circuit board tested, if it is sparking let me know. We have power at the switch so it is not a lack of voltage, the board should send a signal to the electrode to spark, so if it is not sparking I suspect the board is at fault.
