Here is an answer to an often asked question. Oil Burner Electrodes can vary from furnace to furnace and are not always obvious with the furnace burner and serial number as burners are sometimes exchanged by service professionals from the original. Therefore the electrodes might have been changed and need to be matched with that burner. Sometimes burners change within model numbers too. We have found the best way to find which oil burner electrodes you need to purchase is to match the electrodes by shape and size. We do not have a simple way to identify them from your oil burner model number.
Other than the shape, there are three measurements you need; The diameter of the porcelain, the length of the porcelain, and the distance from the end of the porcelain to the end of the tip (measure straight – not along the bends). See diagram on picture attached/below:
We carry a wide number of popular electrodes but we do not carry all of them. We can special order some that we do not stock. We have listed our supplier’s catalog pages on our website that you can use to match up against yours. Goto electrode help page on our website for help )
If you find an electrode on either of these pages that match yours, send us the ‘Cat. No.’ and we will get you a price and availability. Ignore the prices on these pages, they are not accurate.
If you cannot find electrodes that match yours on our website page or on one of the two supplier’s catalog pages, then we most likely cannot get it.
Hope this helps,
