International Comfort Products PGAA18B1K6 Limit Switch
A limit switch was crafted due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts. The limit switch has a sensor in the heat exchanger that senses, or governs, if and when the air is actually warm enough for the main blower to kick in and circulate the air.
Red flags of a bad main limit switch
- The heating and AC system refuses to start or continue to run even though max temp has not been reached
- The HVAC system starts to stop suddenly on more than one occasion
