What 020-024
actually means.
Codes 020 to 024 on an AGA eR7 are a thermocouple differential. Each zone is measured by a duplex thermocouple, two probes in one, and these codes mean the pair have drifted apart in what they report.

What to do when 020-024 shows on the ovenKind of codeTemperature sensor
The reading from the temperature probe fell outside what the control will trust, or climbed far higher than the setting. A loose connector or a probe that has drifted is ruled out before the control itself, and a reading that runs away means the breaker goes off first.
Usually leads toTemperature sensor and calibration
Baking that comes out burnt or pale at the usual setting, traced to the sensor, its wiring or an oven that simply needs calibrating.
Shows up asOven Temperature Not Accurate
Recipes come out burnt or underdone at the right setting, and an oven thermometer reads far from the dial.

eR7 models use duplex thermocouples, which AGA warns can test fine when cold and drift only at cooking heat.
Before you book,
in this order.
Each step comes from AGA's own guidance for 020-024 on its ovens. Follow it to the end: the last card says whether this is a visit.
Note the exact number from the handset.
Watch whether one oven feels hotter or cooler than its setting and tell the technician which.
Book a visit; AGA's remedy is to exchange the thermocouple.
Still there?
It usually turns into temperature sensor and calibration. Book with the code and the model number.
What not to do
A 020-024 code is not an open or broken probe; that is logged as 060 to 100. Here both halves still read, just not alike.
