Whirlpool Refrigerator HI / LO Error Code

Whirlpool documents HI or LO for undercounter refrigerators and beverage centers, but the public guidance does not say what either identifier means. It supports one one-minute power reset, an operation check, and service if the display returns.

Applies to Whirlpool undercounter refrigerator or beverage center

What the appliance detected

Detected condition

The undercounter refrigerator or beverage center is displaying HI or LO; Whirlpool’s public pages do not define the detected condition.

What may contribute

Possible causes

  • The official public pages do not state a cause for HI or LO.
  • The control may clear after the single power reset Whirlpool documents.
  • A persistent display requires model-specific service rather than a guessed component diagnosis.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the identifier and product

    • Write down whether the display shows HI or LO.
    • Record the complete model number and whether the product is an undercounter refrigerator or beverage center.

  2. Power cycle once if safe

    • Disconnect power for one minute if it can be done safely.
    • Restore power and monitor the unit for one minute.

  3. Verify operation

    • Confirm the unit resumes normal operation.
    • If HI or LO remains, request service instead of opening the cabinet.

Actions not recommended

  • Do not access refrigeration, compressor, wiring, or control parts.
  • Do not test live electrical components.
  • Do not ignore unsafe storage temperatures.

When to stop and request service

  • HI or LO remains after the documented power reset.
  • Stored food or beverages may be unsafe.
  • The unit does not resume normal cooling.
