What E62 Means
Over-the-Range Microwave: KitchenAid publishes for E62 "The Oven Sensor circuit reported a shorted condition to the control board. There may a problem with the Sensor, the Appliance Control Board, or the associated wiring." A shorted oven sensor circuit typically presents to the board as an impossibly high cavity temperature, which is a reading the appliance must not act on. Stopping is the designed response. KitchenAid publishes the same sentence for the next code in this series and keeps the two on separate pages.
Common Causes of E62
- An oven sensor failed short
- A chafed harness shorting the sensor circuit
- A control board input that has failed short
🔧 One Safe Check You Can Try
Switch off the cooking surface underneath and let it cool before you stand at the appliance at all - an over-the-range unit puts your forearms directly above a range, and a burn from a hot hob is the injury that actually happens while people are troubleshooting a microwave. Then power the unit down by switching off the circuit breakers for one minute, power it back up, watch the microwave for one minute to see whether the code returns, and verify the microwave operates.
⚠ Why You Shouldn't Go Further Than That
- A short in a temperature circuit means the appliance is being told something that cannot be true, and a board acting on that reading is exactly what the shutdown is preventing.
- 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.
- Getting inside an over-the-range microwave means unbolting it from the cabinet above and lifting it clear of the range below, which needs two people and a clear cooktop before anything else.
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.
