U-Line Refrigerator Code Evap T Short: Shorted Coil Sensor
Evap T Short tells you the refrigerator's control found a shorted circuit at the evaporator thermistor, so the coil temperature it reads cannot be relied on to run cooling correctly.
What does U-Line refrigerator & drawers code Evap T Short mean?
Evap T Short appears on a U-Line refrigerator when its digital control finds the coil sensor wiring bridged. The evaporator thermistor watches the cold coil. When its circuit is shorted, the wires or the sensor look like they are touching and the reading drops to an impossible value. The control refuses to act on it and shows the message. This points at the sensor, a pinched wire or a damp connector rather than at what you stored inside. Cooling control from the coil is limited until the reading is trustworthy again.

How the refrigerator & drawers detects Evap T Short
The evaporator thermistor is a temperature-sensitive resistor mounted at the cold coil of the refrigerator. The control sends a small signal through it and measures the result. A warm coil and a cold coil each give a value inside a known span.
With a short, the signal finds a nearly free path and the measured resistance falls below anything a real coil could produce. The control treats that as a circuit problem, not a temperature, and displays Evap T Short. Because defrost and cooling decisions lean on the coil reading, the control stops trusting that input until the circuit measures normally again.
Likely causes of Evap T Short
- A thermistor wire that is pinched, rubbed through or otherwise damaged
- A thermistor sensor that has failed and now reads as a dead short
- Moisture on the sensor connector creating a path between its pins
Can you keep using the refrigerator & drawers with Evap T Short?
Because this message points to a sensor circuit, the unit is not an immediate hazard, but its cooling may not be well controlled. Move delicate food to another cold place, track shelf temperature with a thermometer and stay away from wet cords. If water is near the plug or outlet, unplug the unit only when it is dry and safe to reach.
What you can safely check
- Unplug the unit or turn off its breaker first, and keep your hands dry because moisture may be involved.
- Wipe up any water you can see around the base and door area, and let the interior air out for a few minutes.
- Restore power once and see whether Evap T Short returns.
- Keep a refrigerator thermometer on a middle shelf and note the reading.
- Leave panels and wiring alone. If the message comes back, call us.
What our technician does for Evap T Short
- Measure the evaporator thermistor circuit for a short
- Look for pinched, chafed or wet wiring and connector pins
- Dry or replace a damaged connector or wire section
- Replace the thermistor when its readings are wrong, then verify normal coil readings
How to keep Evap T Short from coming back
- Wipe spills and condensation promptly so moisture does not reach wiring and connectors.
- Keep humid spaces ventilated; damp air in a garage or on a lanai can collect on connectors.

Evap T Short questions
What does Evap T Short mean?
It means the control sees a shorted circuit at the evaporator thermistor. The reading it gets is far outside what a real coil could produce, so it flags a sensor or wiring problem instead.
Can moisture cause Evap T Short?
Yes, water on a connector can bridge the pins and look like a short. Drying the area may help for a while, but a technician should confirm the connector is sound before you rely on it.
Will Evap T Short stop the refrigerator from cooling?
Not always right away. The unit may still cool, though less precisely. Watch the shelf temperature, because poor coil control can lead to warming or frost buildup over time.
How is Evap T Short different from Evap T Open?
Short means the sensor circuit is bridged and reads almost no resistance. Open means the path is broken. The same sensor is involved, but pinched or wet wiring fits Short more than Open.
What happens if I ignore Evap T Short?
The control keeps running without a good coil reading, so cooling and defrost decisions can drift. Over time the interior may warm or ice may form. Early service is simpler than waiting for food loss.
Need help with Evap T Short?
A technician finds the cause at your bar or lanai and puts the price in writing before any part comes out.
