International Comfort Products FBF050B12A3 Limit Switch
The limit switch contains a sensor in the heating area that decides when the heated air is warmed to a point for the main blower to kick in and circulate the air. Limit switches exist because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Red flags limit switch will need to be replaced
