International Comfort Products H8MPL050B12A1 Limit Switch
One big reason why limit switches are designed that way is because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. A normal limit switch is a type of sensor switch in the heat exchanger that makes the determination when the air is warmed to a point that it can be circulated throughout the house.
Clues main limit switch will need to be replaced
- The International Comfort Products system is starting to runs uneven repeatedly
- The HVAC system refuses to start nor will it stay running as it should
