Samsung Refrigerator is Not Cooling

Refrigerators have come a long way, now complete with the ability to scan for issues. If your Samsung refrigerator finds a problem, whether major or minor, it will flash an error code on the display. Unfortunately, that’s all it ever does—it doesn’t even bother telling you what the error code means.

What do you do then? Well, you could check your owner’s manual, but perhaps you lost yours. No worries! The answers you seek are here. Below is an exhausting list of Samsung refrigerator error codes.

Samsung Refrigerator Error Codes and What They Mean

There are several kinds of error codes specific to Samsung refrigerators. Rather than guess what the error is, consult the list below. Match your error code and move accordingly. To troubleshoot many error codes, a multimeter (View on Amazon) is necessary to read sensor resistance.

Error Code 1 E

Inside your freezer is a temperature sensor. If that sensor fails, it can cause irregularity in the temperature. After shutting off your Samsung fridge and unplugging it from the wall, use your multimeter to check the resistance of the temperature sensor.

Important: As a homeowner, realizing that you need to waste another Saturday waiting for the landlord or handyman to come over to fix another damaged appliance is frustrating. It shouldn't feel like the norm to constantly have damaged appliances and systems in your home since it can come to a huge cost at the end of each year.

The Home Improvement Solutions eBook covers everything you need to do in your home when it comes to maintenance and improvement so you can avoid wasting another weekend waiting for someone to come to your rescue.  

It should read around 13,000 ohms at 32 degrees. You have 10 percent wiggle room up or down in terms of ohms. Check the wiring on the control board associated with the temperature sensor CN30 and CN76, red and grey, respectively.

Error Code 2 E

On the other end of the spectrum is the refrigerator compartment temperature sensor. Like the freezer temperature sensor, if it reads way over 13,000 ohms using the multimeter, it’s time to have it replaced. The wiring is associated with CN30 and CN76, white and gray wiring.

Error Code 4 E

Still in the same family of sensors, you have the freezer evaporator defrost temperature sensor. When it fails, you get error code 4 E. Using the multimeter you should be reading around 13,000 ohms, give or take 10 percent. Check the wiring; CN30 and CN76, orange and grey wiring, respectively.

Error Code 5 E

Another member of the family of sensors, there’s the refrigerator evaporator defrost temperature sensor. Yet another sensor that has a reading of 13,000 ohms, give or take 10 percent. The wiring is colored sky blue and grey, associated with CN30 and CN76.

Error Code 6 E

We aren’t done yet with sensors. Error code 6 E refers to an ambient temperature sensor failure. The ohm reading should be around 5,500 if it’s subjected to a temperature of 72 degrees Fahrenheit. Check the wiring at CN78; it’s colored yellow.

Error Code 7 E

Your fridge’s pantry has its own temperature. And if it fails, you get error code 7 E. At 37 degrees Fahrenheit, the multimeter should be reading the sensor for 11,700 ohms. Check for any disconnected wires by CN30 and CN76, colored yellow and grey.

Error Code 13 E

When the humidity sensor isn’t reading correctly, and it fails, you’ll get error code 13 E. Not ideal, to say the least. It’s a bit tougher reading the resistance for the humidity sensor. In order to do so, you have to disconnect the sensor. There’s a yellow and gray wire, test them. They should read 50 ohms, give or take four or five.

Error Code 14 E

Another sensor that can be a pain to measure, the ice maker temperature sensor. If it fails, you’ll see error code 14 E. Disconnect the sensor and look for a white wire on pin 6 and a blue wire. The multimeter should be reading 13,000 ohms with 10 percent wiggle room (if the sensor is subjected to temperatures of 32 degrees Fahrenheit).

Error Code 15 E

The final error code associated with sensors, error code 15 E appears when the ice room temperature sensor fails. Measure with your multimeter and hope that you get 13,000 ohms (if the sensor is subjected to temperatures of 32 degrees Fahrenheit).

Error Code 21 E

Moving away from sensors and targeting the freezer evaporator fan. When the fan fails, you get error code 21 E. What’s important is that the fan isn’t experiencing any ice buildup, not even frost. If there is frost or ice, the fan should be removed, cleaned, and then reconnected. While you’re at it, you might as well check the wiring for any damage, too.

Error Code 22 E

The refrigerator has a fan, too. If it fails, you see error code 22 E. It too cannot experience a buildup of ice or frost, especially if it’s hindering the rotation of the fan. Defrost any buildup and check the wiring.

Error Code 23 E

The condenser also has a fan of its own. While frost and ice won’t typically block the condenser fan, any objects that may have fallen in can. Check for a blockage. You also want to make sure none of the wires are disconnected.

Error Code 24 E

With an error code 24 E, there’s very little you can do except contact a professional to personally fix your Samsung refrigerator. This error points to a failure with your freezer evaporator defrost system.

Error Code 25 E

To check the validity of error code 25 E, you need to reach the control board. In this case, the refrigerator evaporator defrost system has failed. Measure the wires connected to CN70, which are typically white and grey wires. You should be getting a reading of about 120 ohms.

Error Code 26 E

The ice maker is very sensitive to temperature. Anything more than 15 degrees Fahrenheit and it won’t cycle through. But if the temperature is indeed reading 15 degrees or less, then check the gasket for any damage. If you see any, you have no choice but to replace it.

Error Code 27 E

An error code 27 E, you’re dealing with the pantry drawer’s air damper heater failing. You’ll want to check for any disconnected wires. On your multimeter tool, ohms shouldn’t be any more than 135. If you’re seeing an infinity sign, well, then it’s due for a replacement.

Error Code 33 E

If the ice maker fill tube heater is giving you problems, specifically failing, then you’ll need to check the resistance to determine if it needs replaced or not. Locate CN79 on the control board. Disconnect it. Test the yellow and pink wiring for a reading of 102 ohms.

Error Code 41 E or Pc Er

Not an ideal error code to see. Error code 41 E or Pc Er means both the control panel and the electronic control board aren’t communicating like they should be. It could be wiring or one of the components is faulty.

Error Code 81 E

Error code 81 E means the compressor tried to start, and then failed. You could check the wiring that connects the compressor to the inverter board, but it’s better to have a professional service your Samsung refrigerator.

Error Code 82 E

The inverter board is connected to the compressor with wiring. If there’s any failure or disconnected wires, you get error code 82 E. Repair, connect, or replace any wiring. If not replace the board itself.

Error Code 84 E

If you see this error code, immediately call a professional. Error code 84 E refers to the compressor locking up. Repairs are in order or a complete replacement.

Error Code 85 E

If you see this error code, immediately call a professional. Error code 85 E refers to the compressor getting too low of a dose of electricity.

Error Code 86 E

If you see this error code, immediately call a professional. Error code 86 E refers to the compressor getting too high of a dose of electricity.
