International Comfort Products CHP448AKA1 Limit Switch
The limit switch has a sensor located in the furnace that decides when the air is warm enough for the air to begin normal home circulation. One big reason why limit switches are designed that way is because if the air never warms up then the house will never get warm enough.
What warnings are present when my limit switch is almost dead?
- System will not begin the ignition sequence or continue to run longer that five minutes
- The HVAC system starts to erratically more often than not
