Carrier LJE Limit Switch
The limit switch is a switch in the heating area that senses, or governs, if and when the air is warmed to a point for the blower to be activated. A limit switch was crafted due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Clues to watch for to know main limit switch will need replacing
- The heating and AC system will not begin nor will it stay running as it should
- The system is beginning to behave erratically time after time
