UC-15I Ice Maker Auto Delay Feature


  • What is the repeat delay function on the UC-15I?
  • How is the auto repeat delay function set on UC-15I?
  • How many hours can auto repeat delay be set on the Undercounter Ice Maker model UC-15I?


UC-15I Undercounter Ice Makers have an auto delay feature to delay ice production for 24 hours.

  • The ice maker does not make ice when the unit is in Delay or Repeat Delay mode.
  • Ice melts inside the bin during the delay. How much ice is dependent on the ambient temperature and the amount of ice in the bin.
  • Setting a repeat delay allows for targeted ice production during the times when ice is most used every day. The Repeat Delay stays set until the Repeat Delay is disabled, or a power failure occurs.
  • After power failure, Repeat Delay turns off so it must be reactivated.
  • If the ice maker is in the middle of a cycle, it may be possible to hear one batch of ice drop after repeat delay is turned on.
  • Repeat Delay is only available starting with the following serial numbers:
ModelRepeat Delay Starting Serial #

To initiate Repeat Delay:

  1. With the unit turned off, touch Delay one, two, or three times.
    • Touch Delay once for a 2-hour delay.
    • Touch Delay twice for a 4-hour delay.
    • Touch Delay three times for an 8-hour delay.
  2. Do not turn the unit back on. It will start after the selected delay period.
  3. The automatic delay will occur every 24 hours at the set time, but must be reset after a power outage.
  4. The ice maker will not produce ice during the set delay time.
    • The delay will repeat every 24 hours from the time the automatic delay was entered.
    • Example: If an automatic delay is turned on at 2 p.m. for a two-hour delay period, the unit will not make ice until 4 p.m. The unit will repeat this delay from 2 to 4 p.m. daily until the feature is turned off.
  5. To cancel repeat delay, turn the unit off, then back on.
  6. See UC-15I Use and Care for further details.
