Goodman DSXC160361 Limit Switch
Limit switches exist because if the air never warms up then you will never get hot air through the ducts. The limit switch is a switch located in the furnace that makes the determination when the air is warm enough for the main blower to kick in and circulate the air.
Subtle cues of an unhealthy limit type switch
- The heating and AC system refuses to start or continue to run longer than a minute
- The HVAC system starts to go through the startup sequence but stops quickly time after time
