Carrier 48XP036060300 Limit Switch
A normal limit switch is a switch in the air handler that can determine when the heated air is warmed to a point for the air to begin normal home circulation. The main reason limit switches are made is because if the warmed air is too cool then you will never get hot air through the ducts.
Major signs critical limit switch needs replacing ASAP
- The heating and AC system refuses to kick in or run for any significant length if time
- The whole system is beginning to runs uneven more than once
