Nordyne FG7SK Limit Switch
A normal limit switch is a switch in the heating area that makes the determination when the air is warmed to a point for the main blower to kick in and circulate the air. One big reason why limit switches are designed that way is because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Symptoms limit switch is in need of replacing
- The HVAC system begins to act differently frequently
- The heating and cooling system will not begin the ignition sequence or continue to run longer than a minute
