The gas control valve in our Johnson furnace is leaking. The model # of the furnace is HAS 130A and the serial# is 035461. The gas control valve is an Essex valve the# is 190-2002-26. How can I find one? HELP!

Is there a comparable one that can race the Essex valve? Jimmy'sJimmy's

Yes, just go with a basic honeywell valve. They come in two sizes 3/4" or 1/2". Most are 1/2", so you will need to check yours.
