International Comfort Products PHF042K000A Limit Switch
A normal limit switch has a sensor in the heating area that determines when the heated air is warmed to a point to activate the main blower. The main reason limit switches are made is due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air.
General indicators that your limit type switch needs a replacement ASAP
- Your system is starting to act differently more often than not
- The HVAC system will not even start nor will it stay running longer than 10 minutes
