Each eR7 plate and oven is measured by a duplex thermocouple, two sensors built into one probe. Codes 020 to 024 mean the two readings have drifted too far apart, and AGA's answer for this group is a new thermocouple. AGA stove display · also shown as 020, 021, 022, 023, 024 What to do when 020-024 shows on the stove ### Kind of code Temperature sensor The thin probe on the back wall of the oven sent the stove a reading it would not trust, or one that kept climbing past the setting. A loose plug behind the stove or a probe knocked against the racks is ruled out before the sensor or the board is replaced. If the oven keeps getting hotter with the controls turned off, switch the stove off at its breaker first. ### Usually leads to Stove oven heating repair The oven part of a stove that stays cold, heats slowly or bakes too hot or too cool, fixed at the bake and broil elements, the oven igniter, the gas valve or the temperature sensor. ### Shows up as Stove Error Code The stove shows letters and numbers, a flashing symbol or a short message, beeps, and the oven or a burner stops or will not start. ### Make AGA A British name in home cooking, part of the Middleby group, best known for the cast-iron stove that stays warm all day. ### Source AGA eR7 field service manual, USA and Canada (AGA owner's guides library) eR7 cookers; every zone, the two hotplates included, uses the same type of duplex thermocouple. ## Before you book, in this order. Each step comes from AGA's own guidance for 020-024 on its stoves. Follow it to the end: the last card says whether this is a visit. 01 Note the exact number, since it narrows down which zone is involved. 02 Watch which plate or oven seems to overshoot or lag, and tell the technician. 03 Book a visit; the two readings are watched at cooking heat with service software before the probe is changed. ### Still there? It usually turns into [stove oven heating repair](https://stoverepair.center/services/stove-oven-heating-repair/). Book with the code and the model number. ### What not to do A drifting probe does not always show itself when the cooker is cold. AGA notes these probes can test fine at room temperature and only separate once hot, so a quick check on a cool cooker can miss it. ## What you may notice with it.

Note the exact number, since it narrows down which zone is involved. If it comes back, it needs a visit. ### Why does my AGA only show 021 once it is hot? According to AGA, these probes often test fine on a cold cooker and only separate once they are at cooking heat. So the code tends to show after warm-up, and a technician tests the probe hot. ### Is the same probe used in every zone of my AGA eR7? Yes. AGA uses one duplex thermocouple type for all zones, so a replacement is not tied to one plate or oven, though the technician still confirms which zone is drifting. ### Can my AGA eR7 keep cooking with a code in the 020s? The zone may run too hot or too cool because its sensor readings disagree. Avoid relying on that plate or oven for anything precise and book a visit. --- **[Read on the site: AGA eR7 handset showing a code from 020 to 024](https://stoverepair.center/error-codes/aga-020-024/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
