If your fridge still isn’t cooling after basic troubleshooting, it’s best to call a professional.
When a Simple Reset Helps
Sometimes your refrigerator just needs a quick reboot. Unplugging the appliance for 10–15 minutes and then plugging it back in works like a soft reset for the system. This simple step can clear minor electronic glitches, reset the control board, and help the cooling cycle start again. In many cases, homeowners are surprised to find that after a short reset, the fridge begins cooling normally. It’s especially useful if your refrigerator has been running continuously without a break or if there was a recent power surge. While this trick won’t solve deeper mechanical problems, it’s worth trying before moving on to more complex troubleshooting.
