Samsung AVMHC128EA0 Limit Switch
A normal limit switch is a switch located in the furnace that senses, or governs, if and when the air is actually warm enough so that it may be pushed through the ducts and out the vents. The reason limit switches exist is because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air.
Signs limit switch is dying
- The HVAC system refuses to start nor will it stay running like it should
- The whole system is starting to run inconsistently time after time
