Rheem RSNA-B Series Limit Switch
Limit switches were created due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. The limit switch contains a sensor in the heat exchanger that senses, or governs, when the air is warmed to a point for the blower to be activated.
What warnings are present when my limit switch most likely is not working right?
- The heating and AC system is unable to start or run well for any length of time
- The whole system begins to shut down unexpectedly on a regular basis
