Goodman ARPF19311 Limit Switch
A normal limit switch is a switch in the air handler that decides when the air is actually warm enough for the air to begin normal home circulation. One big reason why limit switches are designed that way is because if the air never warms up then you will never get hot air through the ducts.
Clues of a bad critical limit switch
- Your system begins to become inconsistent from time to time
- The HVAC system will not begin the ignition sequence or run longer that five minutes
