Friedrich P12B Limit Switch
The limit switch is a switch in the air handler that decides when the heated air is actually warm enough for the air to begin normal home circulation. Limit switches were created because if the warmed air is too cool then you will never get hot air through the ducts.
Important clues to watch for in a failing limit switch
- The system is starting to act weird on a regular basis
- The heating and AC system refuses to start or run for any length of time
