Nordyne FG7TL Limit Switch
A limit switch was crafted because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. A normal limit switch is a switch in the heating area that decides if and when the air is warm enough for the air to begin normal home circulation.
Warnings of a poorly performing main limit switch
- The Nordyne system starts to become unpredictable more often than not
- The heating and AC system refuses to kick in or run well longer than a minute
