KitchenAid Countertop Microwave: flashing colon in the clock display

What Colon Flashing means

On KitchenAid countertop microwaves such as the KCMS1555SSS or KCMS1655BSS, a flashing colon between the digits means the time is being set. That is normal behavior, and there is nothing to repair. If the colon flashes when you expect the clock to show a steady time, it usually means the clock has not been set or the power was interrupted.

Common causes of Colon Flashing

The clock is in set mode after a power interruption
Time setting was started but not finished
A brief outage that cleared the stored time

✓ One safe check you can try

1. Press Clock and enter the time. 2. Finish by pressing Start or Clock, depending on your model's prompt. 3. Watch the colon; a steady colon means the time is set. 4. If it keeps flashing after setting, unplug the microwave for a minute and try again. 5. Call us only if the display still behaves oddly.

! Why to stop there

Nothing is broken when the colon flashes while setting the time
A visit would cost you money for no reason
We would rather tell you that on the phone, and quote any repair in writing first

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Colon FlashingColon Flashing questions

Is a flashing colon an error code?

No. It is the normal sign that the time is being set or needs setting.

Why did it start flashing after a storm?

A power interruption clears the clock. The colon flashes until you set the time again.

When should I worry?

If the display shows other characters, beeps, or the keypad does not respond, a real problem may exist.
