The eR7's main board carries a configuration key that tells it what electrical supply the range is on. Code 140 means no key is fitted or the key does not match the phase of the supply the range is connected to. AGA range display What to do when 140 shows on the range ### Kind of code Controls and communication The display, the main board or the induction power board lost contact with one another, or one of them failed its own self-check. A power dip, a loose cable or moisture from a boil-over is ruled out before a board is replaced, and a range that keeps heating while this code shows is switched off at the breaker. ### Usually leads to Knobs, switches and controls Knobs that spin or crack, touch keys that do nothing, blank displays, clocks that reset and control boards that switch the wrong thing. ### Shows up as Range Error Code The range display shows letters, numbers or a flashing symbol, beeps, and stops the oven, a cooking zone or a clean. ### Make AGA A British cooking name, owned by Middleby, that sells cast-iron heat-storage cookers and more conventional dual-fuel and induction ranges in the US. ### Source AGA eR7 Field Service Manual, USA and Canada eR7 ranges; in standby the main board can show the key setting next to the connected supply. ## Before you book, in this order.

Note 140 and whether it appeared after installation or electrical work. If it comes back, it needs a visit. ### Why would error 140 show on a newly installed AGA eR7? The key on the main board has to match the supply the range is wired to. A missing key or a mismatch after installation produces 140. ### Is 140 on an AGA eR7 something I can reset myself? No. It is a setup item on the main board, checked with the supply during a service visit. --- **[Read on the site: AGA eR7 range showing error 140 | RangeRepair.center](https://rangerepair.center/error-codes/aga-140/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
