International Comfort Products PGAD24B1K5 Limit Switch
The main reason limit switches are made is because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch is a type of sensor switch in the heating area that senses, or governs, when the heated air is warm enough to activate the main blower.
What are the signs that the limit switch is failing?
- Your system is starting to run inconsistently more often than not
- Your International Comfort Products system will not begin the ignition sequence or run longer than a minute
