They are deliberately unforgiving: if they stop agreeing with each other, the appliance shuts down completely rather than run. It is a good design and a confusing symptom, because from the front the machine simply appears to have died. ### What actually goes wrong - **The interlock switches**, out of adjustment or failed. - **The door latch and its alignment**, which is why the switches went out. - **Control lock**, on by accident. Free. - **The touch panel**, and separately the control board behind it. - **The door handle and hinges**, on an over-the-range unit that gets pulled at from below. ### Where your microwave is fitted matters Over-the-range, built into a cabinet with a trim kit, low profile, a microwave-hood combination, or on a counter. The first four are part of a kitchen, matched to an opening, and that is what usually decides whether a repair or a replacement is the better answer. ### What it costs From $165. The exact cost is confirmed after the on-site diagnostic. What this involves Interlock switches tested as the set they are Control lock and power cycle ruled out first Door alignment corrected, not just the switch replaced Control lock first Most of these lock the panel from a long press on one of the number keys, and it is switched on by accident constantly. It costs nothing to rule out and it ends a fair number of these calls. A proper power cycle Five full minutes at the breaker rather than a few seconds at the plug. On an appliance with a dark display that is the next step before anything is called failed. Test the interlocks together The switches in the door latch are a set and the appliance stops the moment they disagree with each other. That produces a machine that is completely dead with nothing visibly wrong, which is one of the most confusing symptoms in a kitchen. Set the door as well as the switch A door that has dropped is why the switches stopped agreeing. Replacing a switch and leaving the alignment brings the same appointment back in a few months.

The exact cost is confirmed after the on-site diagnostic. ### The buttons do not respond. Try the control lock first — a long press on one of the marked keys usually clears it, and it gets switched on by accident all the time. If the panel is genuinely dead, cut the power at the breaker for five full minutes before assuming a part. After that it is the touch panel or the board, which are separate parts. ### The machine is completely dead and nothing looks wrong. That is very often the door interlocks. There are several switches in the latch and they have to agree; when one goes out of adjustment the appliance stops entirely and shows you nothing. It is a genuine repair and usually a modest one. ### How do I reset the clock after an outage? Through the clock or settings button rather than by unplugging it — and it is worth doing rather than living with a blinking display, because some functions will not run until the time is set. If the display has gone dark entirely, five minutes off at the breaker is the next step. ### What does the repair cost? From $165, with an interlock switch at the low end and a touch panel or control board above it. The exact cost is confirmed after the on-site diagnostic and agreed with you before any part is ordered. --- **[Read full article: Microwave door & control repair](https://kitchenaidmiami.support/services/microwave-door-and-control-repair/)**
