International Comfort Products PGC036K060A Limit Switch
Limit switches are crucial because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts. A normal limit switch contains a sensor in the air handler that senses, or governs, if and when the air is warm enough for the main blower to kick in and circulate the air.
What warnings should I watch out for to know if my critical limit switch has to be replaced?
- Your International Comfort Products system is unable to start or run well longer than a minute
