DO you get a 'spark' from spark electrode when you turn it ON?
Does main flame attempt to light at all?
Your Atwood uses the SAME t-stats and circuits for electric & propane so that part of system is good if electric is heating.
Only part that is separate is the circuit from propane ON/OFF switch to circuit board and circuit board DC to spark electrode and gas valve
Circuit board has 2 push on connectors
Pull both, clean contact surface with pencil eraser and then make sure pins make good contact when you push connector back on
Pull spark electrode high tension wire from transformer on board. Make sure it makes clean/tight contact when you push it back on
Make sure spark electrode assembly screw is tight.....it provides ground
Spark electrode has to be 'engulfed' in main flame..tip red for 'flame proving'
Spark electrode should have a strong spark....very audible 'click'...if not check gap (1/8")
So does it spark......does main flame attempt??
