If the Defrost Timer's Battery Loses Power

If the SET CLOCK, PROGRAM and DEFROST ON lights are all blinking, the backup power supply (battery) to the Defrost Timer has weakened. Estimated battery life is 10 years. The timer can continue to function normally after the battery has weakened if the timer is reprogrammed.

If a power outage occurs and is later restored after the battery has weakened, the following three things happen:

•The defrost clock resumes as if it were 12:00 midnight.

•The position of the switches dictates the defrost schedule. If all switches are OFF, the factory preset times of 2 AM, 8 AM, 2 PM and 8 PM will initiate deftost cycles 2, 8, 14 and 20 hours after power was restored.

•The factory preset defrost duration of 25 minutes is re-invoked.

Because the clock resumed at 12:00 midnight, it must be reset to the current time-of-day to avoid inconvenient defrost cycles. Refer to Setting the Time Clock to the Current Time-of-Day (page 8).

If the Defrost Duration was set at a value other than the factory preset 25 minutes, reset it. If power is lost again, reset again. Refer to Setting the Defrost Duration (page 8).

If you are using a custom Defrost Schedule, the switches must be reset after resetting the time and Defrost Duration. Any defrost start times that are set by the positions of the program switches will override the factory preset defrost start times even if the battery is weakened.

If the battery has weakened and reprogramming the time-of-day, defrost duration and schedule after a power interruption is too inconvenient, the Electronic Defrost Timer can be replaced.

In the event of a power surge or lightning, the SET CLOCK, PROGRAM and DEFROST ON lights will all blink the same as for a weak battery but the battery may not have weakened. First, try to reprogram the Defrost Timer. If the Defrost Timer fails to function normally, contact service.

MECHANICAL DEFROST TIMER (Fig. 19)

When equipped on Freezers or on Convertible Models with Freezer Chambers, when power is initially applied to the cabinet, the exterior dial of the defrost time clock must be set to the correct time of day.

To access the defrost timer, remove the front trim panel (Fig. 2) by lifting up and out. Open door on the defrost timer box. Turn the inside knob counterclockwise until the exterior dial is positioned so the correct time of day is at the time of day pointer. Replace the front trim panel when done.

The defrost timer (Fig. 19) is set at the factory for four 26-minute defrost cycles per day (2 AM, 8 AM, 2 PM and 8 PM). Depending on local conditions, it may be necessary to change the frequency or duration of defrost cycles.

If the power supply is interrupted, the defrost timer must be reset to the correct time of day.
