U-Line Ice Maker Evap T Short: Shorted Evaporator Sensor
Evap T Short points to a bridged evaporator thermistor circuit in your U-Line ice maker. The control cannot trust the evaporator temperature and may stop the ice cycle.
What does U-Line ice machine code Evap T Short mean?
Your U-Line ice maker shows Evap T Short when the evaporator thermistor circuit is shorted. A short means the sensor path is bridged, so the signal looks wrong to the board and the evaporator temperature cannot be trusted. Any one of three things can produce it: a pinched or damaged wire on the thermistor, a worn-out sensor, or moisture sitting on the connector. The display does not identify which applies, only that the evaporator sensor circuit is bridged.

How the ice machine detects Evap T Short
The evaporator is the cold surface where your ice maker freezes water, and a thermistor attached to it reports how cold it is. The sensor's resistance changes with temperature, and the control board turns that into a reading it uses to run the freeze and release steps.
A healthy sensor gives a value somewhere within a normal band. If the circuit is bridged, for example by a pinched wire or a damp connector, the board sees a reading that is far outside that band and cannot match it to a real temperature. It then reports Evap T Short rather than act on bad data, because running the cycle on a wrong evaporator reading could freeze too much or too little.
Likely causes of Evap T Short
- A pinched or damaged wire on the evaporator thermistor
- A thermistor sensor that has failed
- Moisture sitting on the sensor connector
Can you keep using the ice machine with Evap T Short?
You can leave the ice maker plugged in while you wait, but expect little or no normal ice. If you find water around the unit, a hot smell or a buzzing sound, switch it off at the breaker and leave it off. A damp connector deserves a careful look before the unit runs again.
What you can safely check
- Stop the ice maker, unplug it or cut power at the breaker, and shut the water supply valve if one is within easy reach.
- Let it sit for a minute and power it back on.
- Look near the unit for standing water or humidity that could reach the connector area, without removing any panel.
- Watch whether Evap T Short comes back once the cycle begins.
- If it returns, call us and mention any dampness you saw.
What our technician does for Evap T Short
- Inspect the evaporator thermistor wire for pinches or insulation damage
- Check the connector for moisture or corrosion and dry or replace it
- Test the sensor and replace it if the reading is wrong
How to keep Evap T Short from coming back
- Wipe up spills and condensation around the unit promptly
- Keep drain and water lines free of leaks that could drip on connectors
- In humid Florida months, keep the room ventilated so moisture does not build behind the unit
- Avoid squeezing the wiring when you slide the ice maker in or out

Evap T Short questions
Why would moisture cause a short?
Water on a connector can bridge the contacts and make the sensor circuit look shorted to the board. That is why the message can appear in a damp spot and clear after the connector is dried and checked.
Is a shorted sensor dangerous?
It is not a safety problem by itself. It is an electronics reading that cannot be trusted, so the ice maker may stop or work poorly. The main concern is that ice production is affected.
How is this different from Evap T Open?
Both involve the same evaporator sensor. Open means the circuit is broken, while short means it is bridged, and they usually point to different wiring or connector problems.
Can the code disappear once everything dries out?
It can, if moisture on the connector was the only cause. But a pinched wire or a failed sensor will keep producing the message, so a repeat means the circuit needs testing.
Does the maker's warranty cover this?
Check your warranty terms, since coverage depends on the model and how long you have owned it. Have the model and serial number ready, and we can explain what the repair involves.
