I will state that reignitor or the electrode is bad, that is why it was a used part. What the sequence is, you turn on LP at the switch. The control board sends a 12 volt signal to the reignitor, THAT triggers the gas valve to open AND the spark electrode to SPARK. If the spark electrode does NOT spark it shuts down the LP side and you get the check light. As you have found out throwing expensive parts is not the way to go. Go to the spark electrode at the burner. There are 2 types. ONE older style the spark plug wire can be disconnected from the Porcelain clad electrode. This will have a small spade terminal on it. The other type, the wire goes IN
to the Porcelain white part of the electrode and is not removable. IF you have the removable, Disconnect from the electrode, SHUT OFF THE LP GAS!!!!!!!, then start a LP lighting sequence use a screwdriver and see if that electrode wire sparks to the screwdriver, hole the screwdriver about 1/2 inch from the end of the electrode metal spade end. IF it sparks, your Electrode at the burner is bad, replace it. IF your electrode wire cannot disconnect, follow it back to the reignitor. Disconnect the electrode wire from the reignitor and use a small short wire bare on both ends and do the screwdriver test. IF NO SPARK at the reignitor the reignitor is bad. IF it sparks, you replace the Electrode which will come with a new wire. Doug
