International Comfort Products PGF060K100F 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 switch in the heating area that decides when the heated air is actually warm enough for the air to begin normal home circulation.
Key symptoms of a barely functioning limit type switch
- System will not start nor will it stay running like it should
- The International Comfort Products system begins to act weird on more than one occasion
