International Comfort Products H9MPD080J16C1 Limit Switch
Limit switches exist because if the air is not warm enough then the house will never get warm enough. A normal limit switch is a switch located in the furnace that makes the determination when the air is actually warm enough that it can be circulated throughout the house.
What are the indications that my critical limit switch is about to stop working?
- The HVAC system will not begin or run for any significant length if time
- The system is starting to run inconsistently on more than one occasion
