seconds and the icemaker automatically stops. The control board will signal this problem using 7 beeps every 3 seconds.

The icemaker also automatically stops in cases of insufficient voltage (92Vac ± 5% or less). The control board will signal this problem using 6 beeps every 3 seconds.

When the proper supply voltage is resumed, the icemaker automatically starts running again.

f) LED Lights and Audible Alarm Safeties

The control board includes LED indicator lights, audible alarm safeties, and an output test feature. The “POWER OK” LED indicates control voltage and will remain on unless a control voltage problem occurs. The “POWER OK” LED flashes continuously when the bin is full and DV energizes for a maximum of 5 minutes to drain the water tank.

At startup, a 5 second delay occurs to stabilize the circuit. LEDs 4 through 8 energize and sequence from initial startup as listed in the table below. Note that the order of the LEDs from the outer edge of the board is 5, 6, 8, 9, 4, 7. For more information, see “2.
