Samsung UQB24J2WC Limit Switch
The limit switch contains a sensor in the heating area that can determine when the air is actually warm enough for the blower to be activated. Limit switches were created because if the warmed air is too cool then the house will never get warm enough.
Major indications limit type switch will have to be replaced
- The whole system is beginning to behave erratically occasionally
- The heating and AC system will not begin or continue to run for any significant length if time
