International Comfort Products PGF018K040A Limit Switch
One big reason why limit switches are designed that way is due to the fact that if the air inside the furnace is too cool then the house will never get warm enough. The limit switch is a type of sensor switch located in the furnace that decides when the heated air is warm enough that it can be circulated throughout the house.
Major indications of an unhealthy critical limit switch
- The system starts to runs uneven more often than not
- The heating and AC system is unable to start nor will it stay running longer than 10 minutes
