Kenmore Ice Maker HI Error: High Water Temperature / Condenser Over-Temperature
The kenmore ice maker hi error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Ice Maker Error Code HI Mean? HI on a Kenmore Elite 89183 or 89189 stand-alone under-counter ice maker stands for High Temperature. These Scotsman-platform […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. HI is a protective hold, not a mechanical failure. The unit is safe to leave energized while addressing ventilation or water temperature. If HI clears after environmental correction, the ice maker can resume normal use. If HI persists after correcting environment and cleaning the coil, further diagnosis is needed.
Can I reset the code?
Yes. HI will clear automatically on Kenmore Elite 89183/89189 units once temperatures drop within operating range — no manual reset is required. Improving ventilation, cleaning the condenser coil, and ensuring cool water supply allows the machine to resume production on its own within 30–60 minutes.
When to stop immediately?
Stop if you notice: HI persists for more than 2 hours after ventilation is improved and the condenser coil is cleaned, Condenser coil is damaged or bent, preventing adequate fin exposure for airflow.
Symptoms You May Notice
HI indicator flashes on the control panel; ice production pauses
The Kenmore Elite 89xxx control panel displays the HI fault code via LED indicator. The machine suspends the freeze cycle until temperatures fall within operating range, which may happen automatically once ambient or water temperature drops.
Machine restarts on its own after 30–60 minutes in a cooler environment
HI on 89183/89189 units is often a protective hold rather than a hard lockout — if ambient temperature drops or the inlet water cools, the board may automatically resume production without any user intervention.
Ice cubes are smaller than normal or hollow before the HI fault appears
Elevated water temperature slows freeze-cycle progress. Before the board triggers HI, users may notice undersized or partially hollow cubes as the freeze time extends beyond normal limits.
Cabinet exterior and vent area feel unusually warm
The sides and rear vent of the Kenmore Elite 89xxx cabinet radiate more heat than normal because the condenser cannot shed heat efficiently, and warm air blows from the front louvers while the machine attempts to run.
Possible Causes
Ambient temperature above the rated operating range (up to 100 F)
Kenmore Elite 89183/89189 units are rated for ambient air temperatures between 50 F and 100 F. Installation in a hot garage, a closed cabinet without ventilation, or near a heat source pushes the condenser temperature above the HI threshold.
DIY PossibleInlet water temperature above 90 F
Scotsman-platform ice makers require inlet water between 40 F and 90 F. Water fed from an uninsulated hot-side line or from a supply that has been sitting in a sun-exposed pipe arrives too warm to freeze efficiently, triggering HI.
DIY PossibleCondenser coil clogged with dust reducing heat dissipation
A dust-fouled condenser coil on the rear of the 89183/89189 unit cannot reject heat efficiently from the refrigerant, causing refrigerant condensing temperature to rise until the board triggers HI even at normal ambient temperatures.
DIY PossibleSafe Checks You Can Do
-
1
Check installation environment and improve ventilation
Confirm the Kenmore Elite ice maker has at least 2 inches of clearance on all sides per the owner manual specification. If installed in a closed cabinet, verify the cabinet has front venting to allow condenser heat to escape. On a hot day, temporarily move the unit to a cooler room or wait until ambient temperature drops below 90 F and observe whether HI clears automatically.
Kenmore Elite 89xxx units are air-cooled. Recirculating their own exhaust air in a closed cabinet is the single most common installation mistake and will trigger chronic HI faults even in a moderately warm room.

Clean the condenser coil and verify water supply temperature
Unplug the unit and use a vacuum with a soft brush to clean the condenser coil fins at the rear of the machine (accessible behind the rear grille). Also run the cold-water supply at the connection point and feel the water temperature — it should feel comfortably cool, not warm. If the water supply feels warm, let the supply line run for 30 seconds to flush standing water from a sun-heated pipe before connecting.
Condenser coil cleaning on 89183/89189 units is recommended every three months in dusty or pet-hair environments. Annual cleaning is the minimum for most homes. A visibly matted coil will trigger HI at ambient temperatures well below the rated maximum.
When to Call a Professional
Contact a qualified technician if:
- HI persists in a properly ventilated location at ambient temperatures below 85 F after condenser coil cleaning — suggesting low refrigerant charge or condenser fan failure
- Condenser fan motor is not running when the compressor is active
- Refrigerant lines are frosting at abnormal points suggesting a refrigerant charge issue
