Here’s how to initiate a forced defrost cycle on your Samsung RF28HMEDBSR refrigerator. Technicians often use this to quickly test the defrost system or manually melt excessive frost buildup.
How to Enter Forced Defrost Mode (Most Common Method for RF28HMEDBSR):
- Locate the Control Panel: This is the main display panel on the front of the refrigerator, usually above the water/ice dispenser.
- Press and Hold Two Buttons: Simultaneously press and hold the Energy Saver button AND the Fridge (Refrigerator Temperature) button.
- Hold: Keep holding both buttons for approximately 8 to 12 seconds.
- Confirmation:
- You should hear a beep.
- The display will likely go blank for a moment and then might show some codes or flash. Often, it will display “Fd” (which stands for Forced Defrost). Sometimes, it might just beep and return to the normal display while internally entering the mode.
If the above method does not work, you can also try it in the video.
What Happens Next:
- The refrigerator will enter the forced defrost cycle. The compressor and fans should shut off.
- The defrost heater(s) will energize.
- This cycle typically lasts around 20-30 minutes, after which the refrigerator should automatically exit the forced defrost mode and return to normal cooling operation.
How to Manually Exit Forced Defrost Mode:
- The easiest and most reliable way to exit any diagnostic mode on a Samsung refrigerator is to unplug it from the wall outlet for about 60 seconds and then plug it back in. This resets the control board and returns it to normal operation.
- Sometimes, repeating the button combination used to enter the mode might exit it, but unplugging is generally preferred.
IMPORTANT:
- Forced defrost will turn off the compressor and fans and turn on the defrost heater(s) near the evaporator coils (usually behind the back panel in the freezer and sometimes the fridge).
- This is a diagnostic function. If you have persistent frosting issues, there’s likely an underlying problem (defrost sensor, heater, control board, sealed system issue, door seal leak) that needs proper diagnosis and repair.
- Ensure the refrigerator doors are closed during the forced defrost cycle for it to work effectively.
- You might hear slight crackling or sizzling sounds as the heater melts the ice – this is normal.
- Excessive frost melting could lead to water overflowing the drain pan if the drain tube is clogged. Be mindful of potential water on the floor, although usually it drains and evaporates fine.
Use this function judiciously for troubleshooting. You likely need further diagnosis if cooling problems persist after a forced defrost.
