Carrier 38BK Limit Switch
A normal limit switch has a sensor in the air handler that decides when the air is actually warm enough that it can be circulated throughout the house. Limit switches are built due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Subtle cues of an inadequate limit switch
- The heating and cooling system will not begin the ignition sequence or run well like it ought to
- The HVAC system starts to runs spotty frequently
