U-Line Refrigerator Error Code E7

Error code E7 indicates a short circuit in the refrigerator’s third thermostat. The third thermostat is responsible for measuring the temperature in the refrigerator compartment. When the thermostat is shorted, the control board receives an incorrect temperature reading, which can lead to improper refrigerator operation.

Possible causes:

Short circuit in the third thermostat. This is the most likely cause of error code E7. The thermostat can short circuit due to mechanical damage, wear, or moisture.
Control board malfunction. The control board can misinterpret the signal from the thermostat, which will also result in error code E7.
Malfunction of other refrigerator components. In rare cases, error code E7 can be caused by a malfunction of other refrigerator components, such as temperature sensors or fans.

Troubleshooting:

1. Check the third thermostat. Disconnect the thermostat from the control board and measure the resistance between the terminals. The resistance should be within the values specified in the user manual for your refrigerator. If the resistance does not match the specified values, replace the thermostat.

2. Check the control board. If the thermostat is working properly, check the control board for damage. If damage is found, replace the control board.

3. Check other refrigerator components. If the thermostat and control board are working properly, check other refrigerator components, such as temperature sensors or fans. If one of these components is malfunctioning, it can cause error code E7.
