My low speed blower still stays on. Probably Fan limit control Switch. I have two old black Camstat type. Probably one for high speed and one for low speed. I'm guessing one is sticking. Can these be pulled out and cleaned. or should I just buy a new one. I believe its is not made anymore but can find one simular.
THey are obsolete and one is for the fan and usually the other is a limit switch for the burner. Usually we can retrofit a combination fan and limit control but you have to get the right length and combine the wiring and make sure you remove the jumper between the fan and limit switch on the new one. Or call a Pro.
