Product review (4 stars): Useful thermopile for old furnaces
This thermopile has revived our old wall furnace. We couldn't find the part in local stores and finally bought it online. Since the old part doesn't have model number on it, it's a little gamble to buy just based on the online product photo. In the end, it turned out well. I guess there are not many thermopiles with spade connections, which are quite different from those of the newer thermocouples. So if your old furnace stops working, be sure to check the voltage generated from the heated thermopile. If it's much lower than 750 mv, you might make it work again by replacing this little part.
