U-Line Refrigerator Error Code L Evap T Short

L Evap T Short means the control board has detected a short circuit in the left evaporator thermistor circuit. The thermistor is a temperature sensor mounted near the left evaporator coil. When its circuit resistance drops abnormally low due to damaged wiring or a failed sensor, the board logs this fault and may alter or disable normal cooling operation.

A power reset may temporarily clear the error code from the display, but it will return if the underlying short circuit in the thermistor wiring or probe has not been repaired. The fault needs to be physically corrected for the code to stay cleared. Repeated resets without repair can mask the issue and allow cooling performance to degrade.

If only the thermistor probe or cable needs replacement, parts typically range from around $15 to $60 depending on the specific component. Labor for a qualified technician can add $75 to $200 or more depending on your location and the time required for diagnosis and repair. If the control board's thermistor input circuit is found to be faulty, board replacement will significantly increase the total cost.

Start by inspecting the thermistor cable for any pinch points, cuts, or signs of damage along its entire length from the evaporator coil to the control board. Check the connector for corrosion or moisture. If the cable or thermistor probe appears damaged, replace the affected component. Use a multimeter to verify the thermistor reads an appropriate resistance value after any repair before reassembling.

Running the unit with an active L Evap T Short code means the control board is not receiving accurate temperature data from the left evaporator. This can lead to improper cooling, inefficient defrost cycles, or potential food safety issues if temperatures are not maintained correctly. It is best to address the fault promptly rather than continuing to operate the refrigerator in a faulted state.
