International Comfort Products PGF030K060F Limit Switch
Limit switches are crucial because if the warmed air is too cool then the house will never get warm enough. The limit switch has a sensor in the heat exchanger that decides when the heated air is warmed to a point so that it may be pushed through the ducts and out the vents.
What warnings should I watch out for to know if my limit switch is not working right?
- The heating and AC system refuses to kick in or run like it should
- The whole system is beginning to behave erratically on more than one occasion
