42 E
Samsung Refrigerator
Severity: CriticalWhat Does This Error Mean?
The 42 E error means your Samsung refrigerator has a problem with the freezer fan. The evaporator fan that circulates cold air in the freezer has stopped. Food in the freezer may begin to thaw if not addressed quickly.
Affected Models
- RF28R6201SR
- RF23M8070SR
- RS27T5200SR
- Most Samsung French door and side-by-side refrigerators
Common Causes
- Freezer evaporator fan motor has failed
- Ice has built up and frozen the fan blades in place
- Fan blade cracked or broken
- Loose wiring connection to the fan motor
- Defrost system failure causing heavy ice accumulation
How to Fix It
-
Check if the freezer is noticeably warmer than usual.
A failing fan means less cold air circulation. Food may start softening.
-
Turn off the refrigerator and defrost the freezer completely.
Allow 6–12 hours with the doors open. Place towels on the floor to catch water.
-
Plug the fridge back in and listen for the freezer fan running.
After about 10 minutes, you should hear a hum from behind the freezer wall.
-
If the fan doesn't run, check the wiring connection behind the freezer panel.
Only attempt this if you're comfortable with basic appliance disassembly.
-
If the 42 E error persists, call a Samsung-certified technician.
The evaporator fan motor replacement is the most likely repair needed.
When to Call a Professional
If defrosting doesn't fix the 42 E error — the fan motor needs replacement. This requires removing the back panel inside the freezer. Expect repair costs of $150–$320 including parts and labor. Contact Samsung support or a certified appliance technician.
Frequently Asked Questions
How quickly will food spoil if my Samsung freezer fan fails?
Frozen food can stay safe for 24–48 hours in a closed freezer. Keep the freezer door shut as much as possible. If the error isn't resolved within a day, move food to another freezer.
What causes the freezer fan to freeze up on a Samsung refrigerator?
Usually a defrost system failure. If the defrost heater or defrost thermostat fails, ice builds up on the evaporator. Eventually, ice covers the fan and stops it from spinning.
How much does it cost to fix the Samsung refrigerator 42 E error?
If it's ice buildup, a manual defrost is free. An evaporator fan motor replacement costs $150–$320 with labor. If the defrost heater also failed, add $100–$200 to that estimate.
