International Comfort Products PGAA24C1K6 Limit Switch
One big reason why limit switches are designed that way is because if the air never warms up then you will never get hot air through the ducts. A normal limit switch is a switch located in the furnace that decides when the air is warm enough that it can be circulated throughout the house.

- System will not start or run well longer that five minutes
- The whole system starts to runs spotty from time to time
