Carrier 58DLX09010020 Limit Switch
A normal limit switch is a switch in the heating area that decides when the heated air is actually warm enough that it can be circulated throughout the house. The reason limit switches exist is due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
What to see if the limit switch is about to go out?
- Your Carrier system will not start nor will it stay running longer than 30 seconds
- The whole system is beginning to become unpredictable more than once
