If your RV refrigerator displays an FD error code, it typically points to an issue with the defrost sensor. This sensor is located in the freezer compartment and is responsible for monitoring the defrost cycles of the unit. It communicates directly with the control board to ensure proper operation.
When this error appears, the first step is to troubleshoot the sensor using continuity, specifically by checking resistance in ohms. If the sensor shows continuity, the issue may not be with the sensor itself but with the control board. In that case, the control board may need to be replaced.
Before moving forward with any replacement, it’s always best to confirm part availability and ensure the correct diagnosis. Addressing the FD error quickly helps keep your RV refrigerator running smoothly and prevents further issues with cooling performance.
This video provides a clear overview of what the FD error code means and the steps you can take to identify whether the problem lies with the defrost sensor or the control board.
