I have a RF22N9781SG/AA that is not cooling at all, refrigerator nor freezer. i have done all the resets and tips online. when i do the self check 5 sensors come up with issues. Fridge ice maker sensor, fridge ice room temperature sensor. fridge defrost sensor, freezer defrost sensor and flex zone defrost sensor. what would make all 5 sensors act up? they couldn't all go bad at the same time right
Make sure that the unit is leveled. A properly leveled unit can prevent potential cooling issues, noises, or leaks, your refrigerator needs to be level. This link below will show you how to level your fridge and make minor leveling adjustments
If the unit does not appear to have any power at all (the control panel is also blank and none of the lights come on when the door is opened), this is a different issue and needs to be brought up in its own thread.
Make sure the Cooling Off Mode is turned OFF. (see instructions below)
If the refrigerator is not in Cooling Off mode, has power, and is still not cooling at all, unplug the refrigerator (or flip the circuit breaker) for 5 minutes, then plug it back in. Wait about 2 hours and if the refrigerator still does not cool, service is required.
If all of this has been completed then service repairs are what is needed. You may message us with the model code and serial number in order to verify the warranty term.
