Goodman GSX130481 Limit Switch
A normal limit switch is a type of sensor switch in the heating area that decides when the heated air is warm enough so that it may be pushed through the ducts and out the vents. Limit switches are built because if the warmed air is too cool then the house will never get warm enough.
Key signs of a dying critical limit switch
- The system is beginning to erratically occasionally
- The heating and cooling system refuses to start or continue to run longer than 30 seconds
