Trane TCP036F300AC Limit Switch
Limit switches were created because if the air is not warm enough the you will lose all the heat as the air flows through the ducts. The limit switch is a type of sensor switch in the heating area that senses, or governs, when the air is warm enough for the main blower to kick in and circulate the air.
Symptoms limit switch is not going to last much longer
- The system begins to run inconsistently on a regular basis
- Your Trane system refuses to kick in nor will it stay running even though the desired temperature has not been attained
