International Comfort Products PA9536AKA2 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. A normal limit switch has a sensor in the heating area that decides when the heated air is actually warm enough for the air to begin normal home circulation.
Simple warnings that your limit switch is not working right?
- The HVAC system refuses to start or will not stay running as it should
- The system is starting to behave erratically from time to time
