International Comfort Products PGF048K120F Limit Switch
Limit switches are built because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a type of sensor switch in the heat exchanger that can determine when the heated air is actually warm enough for the blower to be activated.
What are the clues to watch out for to know my main limit switch is not working right?
- The HVAC system starts to runs spotty from time to time
- The heating and AC system will not begin the ignition sequence or run well for any length of time
