What ":" or "." in display Means
Built-In Microwave, including the microwave-oven combination: KitchenAid keeps a page for the case where the display shows only a colon or a dot. The text under its own headings says there has been a power failure or the clock time has been turned off, and it sends the owner to the Clock section of the Owner Manual for the instructions that apply to their model. A separate power reset is offered if setting the clock does not resolve it. Nothing is described as broken.
Common Causes of ":" or "." in display
- A power failure that left the appliance without a time
- The clock display switched off deliberately in the settings
- A control state that the documented reset clears
🔧 One Safe Check You Can Try
Set the clock, following the Clock section of the manual for your model - the two causes KitchenAid gives are a power failure and the clock display being switched off, and both are settings rather than faults. If the display still shows nothing but a colon or a dot after that, power the unit down by switching off the circuit breakers for one minute, power it back up, watch the oven for one minute to see whether the code returns, and verify the oven operates.
⚠ Why You Shouldn't Go Further Than That
- Both published causes are settings, so a service call booked before the clock has been set is a call that ends in an explanation rather than a repair.
- The high-voltage capacitor inside a microwave can hold a lethal charge after the unit is unplugged and the display is dead, so the inside of the cabinet is not an owner check at any point in this process, whatever the code turns out to mean.
- If the display is genuinely stuck rather than simply unset, the interface is the suspect, and it is behind a panel on a built-in appliance rather than in front of one.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
