International Comfort Products FBF100F14A1 Limit Switch
A limit switch was crafted due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts. A normal limit switch is a switch in the heat exchanger that senses, or governs, when the heated air is actually warm enough to activate the main blower.
General indicators that your critical limit switch is in dire need of a replacement
- System is unable to start or will not stay running even though max temp has not been reached
- The HVAC system is starting to become unpredictable repeatedly
