Re: error code 12

Error code 12 is a genaric "Flame Failure" code. I suspect that the flame is not hitting the flame sensor or that the sensor is bad. You will need to get to the sensor located on the far left hand side of the unit. If you have the owners manual, it's part #123. Remove it and clean it off. Make sure it is placed back in the heater properly aligned and all the way in. Then try and light it. If it does not stay lit, it may need to be replaced but check out the burner tray for debris not allowing the flame to travel all the way to the sensor. You will have to remove many parts to get to the burner assembly.
