Trane 2TWR1060A1000AA Defrost Sensor Board
The defrost sensor board controls when to launch the defrosting phase in order to keep the outdoor unit free from frost build-up. The defrost sensor board depends on a specific sensor located somewhere by the condenser to make the decision on when to begin.
What signals that my outdoor defrost sensor board is in need of a replacement?
- The primary control board could throw a specific error code when a defrost board fails to initialize
- The whole system may end up not running due to the safety issue that the frost poses
- Defrosting refuses to run especially when there is frost that needs to be removed
