Carrier 50GX036300 Limit Switch
A normal limit switch has a sensor in the heating area that senses, or governs, if and when the air is warm enough that it can be circulated throughout the house. The reason limit switches exist is because if the warmed air is too cool then the house will never get warm enough.
General indicators that your limit switch will have to be replaced
- The whole system starts to act weird on a regular basis
- Your Carrier system will not start or run like it should
