U-Line Refrigerator Code L Evap T Short: Left Coil Sensor Shorted
L Evap T Short means the left evaporator thermistor has a shorted circuit, so the control reads an impossible left coil temperature and flags the sensor instead of using it.
What does U-Line refrigerator & drawers code L Evap T Short mean?
L Evap T Short is a left-side wiring message from a U-Line refrigerator that runs two zones. The L points to the left side. The left evaporator thermistor reads the cold coil on that side, and a short makes its reading drop to a value no real coil could give. The control rejects it and shows the message. The likely area is wiring that is pinched, a sensor that has failed, or a damp connector on the left side, and the right side is not the subject.

How the refrigerator & drawers detects L Evap T Short
Each side of this U-Line refrigerator has its own evaporator thermistor, a resistor that changes value with coil temperature. The control sends a small signal through the left one and reads the result, then uses it to guide cooling and defrost on the left.
A short gives that signal an easy path, so resistance falls to almost nothing. Real coils never reach such a value. The control concludes that the left circuit has a wiring or sensor problem and displays L Evap T Short. It stops trusting the left coil reading, and the left side loses the feedback it needs, while the right side uses a separate sensor of its own.
Likely causes of L Evap T Short
- A pinched or chafed wire on the left evaporator thermistor
- A left evaporator thermistor that has failed and reads as a short
- Moisture on the left sensor connector bridging its pins
Can you keep using the refrigerator & drawers with L Evap T Short?
The message points at a sensor circuit, not at a hazard, so the unit can stay plugged in for a short while. The left side may drift, so use a thermometer and move delicate items to the right. If you find water near the cord or outlet, stay dry, switch off at the breaker and call for service.
What you can safely check
- Remove power at the plug or breaker first, and dry your hands before touching anything on the left side.
- Look at the left compartment for dampness or pooled water and dry it with a towel.
- Restore power after a minute and see whether L Evap T Short comes back.
- Compare a thermometer on the left with one on the right.
- Do not open panels. If the message returns, call us.
What our technician does for L Evap T Short
- Measure the left evaporator thermistor circuit for a short
- Inspect left-side wiring for pinches, wear and moisture
- Dry out the connector and swap any worn wire segment
- Replace the left thermistor and confirm normal coil readings
How to keep L Evap T Short from coming back
- Dry off condensation on the left compartment so moisture does not reach the sensor connector.
- Keep the area behind the unit ventilated, since trapped humidity can collect on wiring.

L Evap T Short questions
What does L Evap T Short mean?
It means the circuit for the left evaporator thermistor is shorted. The reading is impossible for a real coil, so the control displays the message and ignores the sensor.
Can water cause L Evap T Short?
Yes, moisture on the connector can bridge its pins and look like a short. Drying may calm it briefly, but the connector and wire should still be inspected.
Is the right side safe when L Evap T Short shows?
The right side has its own sensor and may work normally. Still check both sides with a thermometer, because a left-side cooling problem can change the overall temperature.
Is L Evap T Short the same as L Evap T Open?
No. A broken path is Open, whereas Short means the left sensor wiring is bridged and reads low. The sensor is the same, but the wiring condition and the repair differ.
What happens if I ignore L Evap T Short?
The left side keeps running without a good coil reading, so cooling and defrost can drift. You might see warming or frost over time. Testing early is simpler than losing food.
