Friedrich VHA09K Limit Switch
Limit switches were created due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a type of sensor switch in the air handler that senses, or governs, when the heated air is warm enough for the air to begin normal home circulation.
Major clues critical limit switch should be replaced
- The HVAC system will not begin or continue to run for any significant length if time
- The system is beginning to act weird on more than one occasion
