Limit switches are crucial due to the fact that if the air inside the furnace is too cool then the house will never get warm enough. The limit switch is a type of sensor switch in the air handler that senses, or governs, when the heated air is warm enough for the main blower to kick in and circulate the air.
Major signs limit switch will need replacing
- The HVAC system is starting to runs spotty more than once
