What the OF r error code actually means

OF r is a special test mode on your Samsung refrigerator, not a standard error. It temporarily turns off cooling to the fridge section while running the compressor at a set speed so a technician can check an internal valve that routes cold air. If you see this on your display and did not intentionally activate a test mode, pressing and holding the relevant control buttons to exit should return the refrigerator to normal operation.

Questions people ask about OF r

What does OF r mean on a Samsung refrigerator?
OF r stands for Fridge-Off Forced Operation mode on a Samsung refrigerator. It is a diagnostic test mode in which the compressor runs at 3600 RPM while the fridge compartment cooling is turned off, allowing technicians to check the TDM valve function. The TDM valve is set to F Valve Open and R Valve Off during this test. This is not a standard fault code and does not necessarily mean something is broken.
Is it safe to leave my Samsung refrigerator running while OF r is displayed?
OF r mode disables cooling to the fresh food compartment while running the compressor at high speed, so food stored in the fridge section will not be kept at safe temperatures during this time. The freezer section behavior in this mode is also altered from normal operation. You should exit OF r mode as quickly as possible if it was not intentionally activated, and avoid leaving the refrigerator in this state for extended periods.
How much does it cost to repair the issue behind the OF r code on a Samsung refrigerator?
If OF r was triggered intentionally as part of a service visit, there may be no repair cost beyond the diagnostic fee, which typically ranges from $75 to $150 depending on your location. If the TDM valve is found to be faulty and needs replacement, parts and labor combined can range from $150 to $350. A control board replacement, if needed, can range from $200 to $500 or more depending on the model.
How do I fix the OF r code on my Samsung refrigerator?
If OF r appeared unintentionally, you can typically exit the mode by pressing and holding the control panel buttons used to enter test mode, or by performing a power cycle by unplugging the unit for a few minutes. If a technician activated the mode intentionally, they will exit it once the TDM valve check is complete. If the code keeps returning on its own, the control board may need to be inspected.
Will resetting my Samsung refrigerator clear the OF r code?
Yes, in most cases a power cycle or exiting the test mode through the control panel will clear OF r and return the refrigerator to normal operation. If the code reappears after a reset without any button input from a user, that points to a deeper issue such as a control board problem that should be diagnosed by a technician.
