Goodman GME80905CX Limit Switch
The reason limit switches exist is because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts. A normal limit switch is a type of sensor switch located in the furnace that makes the determination if and when the air is warmed to a point for the air to begin normal home circulation.
Important clues poorly running critical limit switch
- The heating and AC system refuses to start or run longer than 10 minutes
- The Goodman system is starting to act differently from time to time
