What 1c6c Means
Built-In Microwave, including the microwave-oven combination: the published text for 1c6c is a single sentence - "There may be a problem with the Oven Control, or the associated wiring." On a combination unit the oven control governs both halves of the appliance, the conventional cavity and the microwave side, so a fault logged here is not confined to whichever function you happened to be using when the code appeared. KitchenAid adds no threshold, no symptom and no second cause; the page moves straight to a power reset.
Common Causes of 1c6c
- The oven control failing one of its own internal checks
- The wiring loom between the control and the rest of the appliance loose, chafed or corroded
- Control electronics disturbed by a supply surge or an outage
🔧 One Safe Check You Can Try
Let the appliance cool and leave the door closed, then do the reset from the breaker panel - not by hunting for a plug behind a built-in cabinet: 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. Note what the appliance was doing when 1c6c appeared, because a code that only turns up during one function is worth far more to a technician than a code with no context.
⚠ Why You Shouldn't Go Further Than That
- When the published text names a component and its wiring in the same breath, the wiring is at least as likely as the part, and only a continuity check settles which.
- Everything in this appliance beyond the door and the control panel sits alongside a capacitor that stays charged after the plug is pulled, which is why the published owner procedure stops at the breaker.
- Every timing and cut-off decision in the appliance runs through this board, so a board reseated wrongly can leave the unit running when it should stop rather than simply refusing to work.
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.
