On KitchenAid over-the-range microwave hood combinations such as the KMHS120ESS or KMLS311HSS, "AccuPop Fail" indicates a possible problem with the AccuPop sensor. That sensor watches the popcorn cycle so the microwave can stop at the right moment. When the message shows, popcorn programs are unavailable, though ordinary timed cooking often still works.
1. Press Cancel. 2. Use a fresh, flat bag of popcorn and set it centered on the turntable. 3. Wipe moisture from the cavity. 4. Switch off the microwave's power at the plug or breaker for a minute, then restore it. 5. Use timed cooking if the message returns, and call us.
Usually yes. Regular timed cooking does not rely on the popcorn sensor. Avoid the popcorn key until it has been checked.
Wear, loose wiring or a control error can all cause it. The official note points to the sensor, so that is where testing starts.
Watching and stopping by sound is the way many people do it, but never leave a bag unattended. Overheating popcorn is a fire risk.
A technician diagnoses it on site and gives you the price in writing before any work starts.
