The 120 to 124 group is a cooking-zone overheat. AGA's first suspect is thermocouples plugged into the wrong sockets behind the user panel, so one zone reads another zone's heat. AGA range display What to do when 120-124 shows on the range ### Kind of code Temperature sensor The oven sensor sent a reading the control would not accept, or one that climbed well past the setting. A loose plug or a sensor that has drifted is ruled out before the control board, and a temperature that keeps rising means the range is switched off at the breaker first. ### Usually leads to Temperature sensor and thermostat repair A range oven that bakes hot, bakes slow, takes forever to preheat or posts a sensor code, traced to the sensor probe, the thermostat or the calibration. ### 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; the probe sockets are labeled by zone on the back of the user panel. ## Before you book, in this order. Each step comes from AGA's own guidance for 120-124 on its ranges. Follow it to the end: the last card says whether this is a visit. 01 Stop using the range and note the code. 02 Book a visit, especially if the code follows recent work on the panel or probes. ### Still there? It usually turns into [temperature sensor and thermostat repair](https://rangerepair.center/services/temperature-sensor-and-thermostat-repair/). Book with the code and the model number. ### What not to do An overheat code here does not have to mean the zone was truly too hot. Crossed connections can make a normal zone look like it is running away. ## What you may notice with it. The range problems 120-124 tends to arrive with.

Stop using the range and note the code. If it comes back, it needs a visit. ### Why did 120-124 appear on my AGA eR7 after a probe was replaced? A probe plugged into another zone's socket makes the control compare the wrong readings. AGA checks those connections first when this code shows. ### Is my AGA eR7 actually overheating when it shows 120-124? It may be, or it may only look that way because of swapped probes. Leave it off until the wiring behind the panel has been checked. --- **[Read on the site: AGA eR7 range showing error 120-124 | RangeRepair.center](https://rangerepair.center/error-codes/aga-120-124/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
