International Comfort Products PGF060H140E Limit Switch
The limit switch is a switch in the air handler that decides when the air is actually warm enough for the air to begin normal home circulation. The main reason limit switches are made is because if the warmed air is too cool then you will never get hot air through the ducts.
Red flags of a faulty limit type switch
- The International Comfort Products system is starting to act differently more often than not
- The HVAC system is unable to start or continue to run as it should
