International Comfort Products PA5560AKA1 Limit Switch
A normal limit switch is a type of sensor switch located in the furnace that decides if and when the air is actually warm enough to activate the main blower. One big reason why limit switches are designed that way is because if the warmed air is too cool then the house will never get warm enough.
Warnings limit switch will not live much longer
- The heating and AC system refuses to kick in or run well as it should
- The International Comfort Products system starts to shut down unexpectedly often
