U-Line Ice Maker Error Code R Evap T Short

R Evap T Short means the control board has detected a shorted circuit in the right evaporator thermistor. The thermistor is a temperature sensor positioned near the right evaporator coil, and its resistance has dropped to an abnormally low level, indicating a short in the wiring or the sensor itself. The ice maker will typically suspend normal ice production until the fault is resolved.

You should not attempt to bypass or ignore this error code. The ice maker has suspended normal operation because the control board cannot accurately monitor evaporator temperatures, which means freezing and harvest cycles cannot be managed correctly. Continued operation without a functioning thermistor circuit risks ice quality issues and potential damage to the compressor or evaporator system.

Repair costs vary depending on what has failed. If only the thermistor needs replacement, parts and labor typically fall in the range of $100 to $250. If the wiring harness requires repair or replacement, or if the control board is found to be at fault, costs can rise to the $200 to $500 range or higher depending on your location and the specific model. Getting a diagnostic estimate from a certified technician before authorizing repairs is advisable.

A homeowner with basic mechanical skills can inspect the thermistor cable for visible pinch points, physical damage, or moisture at the connector, and cleaning or repositioning the cable may resolve the issue. However, resistance testing of the thermistor and any wiring repairs or component replacements typically require a multimeter and some familiarity with appliance wiring. If you are not comfortable with electrical diagnostics, a qualified appliance technician is recommended.

A reset may temporarily clear the fault display, but the error will return immediately if the underlying short in the thermistor circuit has not been corrected. The control board continuously monitors the thermistor signal during operation, so any persistent short condition will retrigger the fault code. The root cause must be diagnosed and repaired for the unit to operate normally.
