Limit switch for york diamond 80 model furnace, switch is made ny Norton Model 271N,
Part number 025-32625-000, there's 0402 . This parts have 2 wires with 2 black flat rod( made of flint rock) sticking down , they shattered while I'm trying to clean them.
Since the furnace keep on blowing cold air and there 4 flash on the RED LED, error code on theback of panel says spill limit switch open.
Thanks
Conrad
