Carrier FX4BNF048000AAAA Limit Switch
The limit switch is a switch in the air handler that makes the determination if and when the air is warm enough for the air to begin normal home circulation. Limit switches are built because if the warmed air is too cool then the house will never get warm enough.
General indicators that your main limit switch is in dire straights
- The heating and AC system will not even start or continue to run as it should
- The system is starting to ramp up but then stops time after time
