Carrier 38YCG042 Limit Switch
A normal limit switch contains a sensor in the air handler that decides when the air is warm enough that it can be circulated throughout the house. Limit switches are built because if the warmed air is too cool then you will never get hot air through the ducts.
Red flags of an ailing limit type switch
- The HVAC system begins to runs uneven more than once
- The heating and cooling system refuses to kick in nor will it stay running as it should
