International Comfort Products HAC442GKA4 Limit Switch
The limit switch contains a sensor in the heat exchanger that can determine if and when the air is warm enough that it can be circulated throughout the house. Limit switches are built because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Major indications of an inadequate limit type switch
- The HVAC system will not even start or continue to run longer than 10 minutes
- Your system is beginning to run inconsistently occasionally
