I have a Sears LP gas fired forced air wall furnace. I recently had it cleaned and was told that the gas valve was leaking and needed to be replaced. The model is 867.736374. It is over 30 years old. Looking up the part on Sears indicated that it is no long made. Does anyone know who actually makes the Sears equipment? Or what would be a possible replacement gas valve for this equipment (i.e. alternate mfg.).

Honey well v800 gas valves will replace almost anything. Inless for some reason your valve is super small.
