Carrier 38YCS042 Limit Switch
The limit switch contains a sensor in the heat exchanger that determines when the air is warm enough so that it may be pushed through the ducts and out the vents. Limit switches exist due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.
Key indicators that my limit switch is dying?
- The HVAC system will not even start nor will it stay running for any significant length if time
- The Carrier system begins to shut down unexpectedly more than once
