LG ARNU153SER2 Limit Switch
A limit switch was crafted because if the air is not warm enough the you will lose all the heat as the air flows through the ducts. The limit switch has a sensor in the air handler that senses, or governs, when the air is warm enough for the blower to be activated.
General indicators that your limit type switch is in dire need of a replacement
- The HVAC system refuses to start nor will it stay running even though max temp has not been reached
- The whole system starts to erratically on a regular basis
