Carrier 38EYG030 Limit Switch
The limit switch has a sensor in the heating area that senses, or governs, when the heated air is warm enough for the main blower to kick in and circulate the air. Limit switches are built because if the warmed air is too cool then the house will never get warm enough.
Elements of a bad limit switch
- The system is starting to run erratically on more than one occasion
- The heating and AC system will not begin the ignition sequence or run well like it should
