Symptoms your Whirlpool defrost sensor board will eventually need to be replaced
- Your HVAC system will stop running because of frost blocking the fins on the outside unit
- Defrost mode never kicks in even though there is excessive frost that needs to be removed
- The control board could signify an error code referring to the failed defrost sequence
