Carrier EW Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrosting phase which aids to keep the outdoor unit free from frost build-up. The defrost board relies on a sensor located near the condenser to verify when to begin.
What are some hints that my defrost board is on its last leg?
- The primary control board may throw an error number produced by too much frost
- Defrost mode does not run even though there is a lot of frost on the unit
- Air conditioning may stop working because of the safety features installed

Before buying or ordering do your best and cross-check the correct model and also make a visual inspection so that you are positive that the correct defrost sensor board is being ordered. There is no rule that says you have to install the part by yourself. Locate a pro locally to replace the part.
Feel free to download your manual for help.
