Carrier 38TRA048 Limit Switch
Limit switches were created because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts. The limit switch contains a sensor in the heating area that can determine when the heated air is warmed to a point for the air to begin normal home circulation.
Do you know if your limit switch is about to stop working?
- The HVAC system will not begin the ignition sequence nor will it stay running even though the desired temperature has not been attained
- The Carrier system is starting to go through the startup sequence but stops quickly frequently
