International Comfort Products GPFM48K120F Limit Switch
A limit switch was crafted because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air. The limit switch has a sensor in the heat exchanger that can determine when the heated air is warm enough for the main blower to kick in and circulate the air.
What are the clues to watch out for to know my limit type switch really is in need of replacing?
- System will not start or will not stay running for any significant length if time
- The whole system is beginning to run inconsistently often
