The old 125000 BTU Green Colonial has a fan control limit switch mounted on the side of the fire box with a long tube structure that goes inside the fire box. There are 4 wires that attach to the u-shaped module that is bolted to the piece holding the long tube like apparatus that is attached to the furnace. How can I test this module?

Do you have a make & model of the fan/limit?
