Carrier 38MFQ022 Limit Switch
Limit switches are built because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch contains a sensor in the heat exchanger that senses, or governs, when the air is warmed to a point for the main blower to kick in and circulate the air.
Symptoms limit switch is in need of replacing
- The HVAC system begins to shut down unexpectedly occasionally
- The heating and cooling system refuses to start nor will it stay running longer than 10 minutes
