U-Line Refrigerator Code R Evap T Short: Right Coil Sensor Shorted
R Evap T Short means the right evaporator thermistor has a shorted circuit, so the control sees an impossible right coil temperature and stops relying on that sensor.
What does U-Line refrigerator & drawers code R Evap T Short mean?
R Evap T Short is a right-side wiring message from a U-Line refrigerator that runs two zones. The R identifies the right side. The right evaporator thermistor watches the cold coil for that side, and a short makes its reading fall to a level no real coil could reach. The control will not use it and shows the message. Suspect wiring that was squeezed, a sensor that gave out, or moisture at the right connector, not the left side.

How the refrigerator & drawers detects R Evap T Short
The right evaporator thermistor in this U-Line refrigerator is a resistor whose value follows coil temperature. The control passes a small signal through it and reads what comes back, then uses the number to steer cooling and defrost on the right.
If the circuit shorts, the signal takes an easy shortcut and the measured resistance drops to nearly nothing. Coils do not reach that level. The control labels it a wiring or sensor problem and displays R Evap T Short, then ignores the right coil value. The right side loses its feedback until the circuit reads normally, and the left side continues on its separate sensor.
Likely causes of R Evap T Short
- A pinched or chafed wire at the right evaporator thermistor
- A right evaporator thermistor that has failed and reads as a short
- Moisture on the right sensor connector bridging its pins
Can you keep using the refrigerator & drawers with R Evap T Short?
The message concerns a sensor circuit rather than a hazard, so the unit may stay on for a short while. The right side could drift, so rely on a thermometer and move delicate items to the left. If you see water near the cord or outlet, keep your hands dry, switch off at the breaker and call for service.
What you can safely check
- Take power off at the plug or breaker first, and keep your hands dry before touching the right compartment.
- Check the right compartment for pooled water or dampness and dry it.
- Restore power after a minute and see whether R Evap T Short returns.
- Compare a refrigerator thermometer on the right with one on the left.
- Do not open panels or touch wiring. If the message returns, call us.
What our technician does for R Evap T Short
- Measure the right evaporator thermistor circuit for a short
- Inspect right-side wiring for pinches, wear and moisture
- Dry the connector and replace any chafed wire length
- Replace the right thermistor and verify normal coil readings
How to keep R Evap T Short from coming back
- Towel off condensation in the right compartment so moisture does not creep to the sensor connector.
- Give the back of the unit some air; trapped humidity can settle on wiring in a closed alcove.

R Evap T Short questions
What does R Evap T Short mean?
It means the right evaporator thermistor circuit is shorted. The reading is impossible for a real coil, so the control displays the message and sets that sensor aside.
Can moisture cause R Evap T Short?
Yes, water on the connector can bridge its pins and look like a short. Drying may calm it for a while, but the connector and wire still need an inspection.
Is the left side safe while R Evap T Short shows?
The left side has its own sensor and may work normally. Check both sides with a thermometer, because a right-side cooling problem can shift the overall temperature.
Is R Evap T Short the same as R Evap T Open?
No. Open describes a broken path, but Short describes bridged wiring on the right sensor that reads low. The sensor is the same, but the wiring condition and fix differ.
What happens if R Evap T Short is ignored?
The right side keeps running without a good coil reading, so cooling and defrost can wander. You might see warming or frost over time. Early testing costs less than lost food.
