However, before you check and solve problems pertaining to this error code, you should ensure that the freezer door closes properly.

This is because keeping the door of your Kenmore refrigerator open for a long time can also give out a signal indicating the error code Er 1F. 

Apart from the icing getting blocked, other phenomena can also trigger this error code on your Kenmore refrigerator.

For example, defects in the circuit and main control board failure can also cause your fridge to give out this code. 

If this error code persists in your refrigerator, you should check out the wiring harness and the power control board.

This is because minor alterations in their functioning can also cause this error to appear on the temperature display of your Kenmore refrigerator. 

Kenmore Refrigerator Error Code Er CO

Kenmore Refrigerator Error Codes

The Kenmore refrigerator error code Er CO indicates an error in communication between the main power board and the control board of the display unit.

This error code can possess high levels of sophistication; therefore, hiring professionals to look when it pops up is advisable. 

Er CO symbolizes a communication error. Therefore the display control board, the power control board, and the wiring harness are the central components to check when you notice this error code. 

This is quite a unique error code that rarely occurs on your Kenmore refrigerator.

Although you may notice this code on the temperature display of your bottom freezer refrigerator, most designs of the Kenmore elite refrigerator are prestigious for not running into these issues.

This is because specific improvements and upgrades have worked to tackle these problems on your Kenmore refrigerator.

When your Kenmore refrigerator displays this error code, ensure to check both the main power board and the display control board for burns or minor faults.

You should do this carefully because even the littlest scratches can prove fatal for these components. Consequently, it would help if you replaced any board with defects.

Kenmore Refrigerator Error Code Er DH

This error code occurs when there’s a malfunction in the defrost mode of your Kenmore refrigerator.

If the defrost sensor does not attain the required temperatures of 40°F after the programmed time, this error code interrupts the system.

However, note that this error code only comes up at the beginning of the defrost process.

This problem occurs when there’s an abrupt sensor short wiring in several instances. This prevents the sensors from reaching the expected temperatures and instantly triggers this error code on your Kenmore refrigerator.

However, several other factors can also cause this code to display on your refrigerator.

To troubleshoot this error code, test-run the fuse and heater to understand how well they’re working. Also, check the main control board to see if any faults might have triggered this error code. 

The heater, fuse, and main control board are the components to check when this error code pops up on your temperature display.

First, however, you should study the relay on the control board, the defrost heater, and the controller to unmask the main problems. 

Kenmore Refrigerator Error Code 22 22

This error code only comes up when the ice maker fan motor of your Kenmore refrigerator is damaged. And a damaged ice maker fan motor usually shows itself by giving out a click-click sound.

So, because the control center does not receive a signal from the compressor, this error code automatically pops up.

You may have noticed that your Kenmore refrigerator has depreciated in its swiftness in cooling the materials you place in them.

So, as this condition progresses, this error would come into play, disrupting the functionality of your refrigerator.

In most instances where this code pops up, Kenmore refrigerator users have to go for the replacement of these fans or other components attached to them.
