AGA eR7 range
showing 020-024
Each eR7 zone is measured by a duplex thermocouple, two sensors in one probe, and 020 to 024 means their readings have drifted too far apart.

What 020-024
actually means.
Each eR7 zone is measured by a duplex thermocouple, two sensors in one probe, and 020 to 024 means their readings have drifted too far apart. AGA's action for this group is a new thermocouple.

What to do when 020-024 shows on the rangeKind of codeTemperature 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 toTemperature 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 asRange Error Code
The range display shows letters, numbers or a flashing symbol, beeps, and stops the oven, a cooking zone or a clean.

Before you book,
in this order.
Each step comes from AGA's own guidance for 020-024 on its ranges. Follow it to the end: the last card says whether this is a visit.
Note the exact number shown on the handset.
Book a visit; the technician watches both readings at cooking heat with service software before exchanging the probe.
Still there?
It usually turns into temperature sensor and thermostat repair. Book with the code and the model number.
What not to do
A probe that tests fine on a cold range can still be the cause, since AGA has seen thermocouples drift apart only when hot.

AGA range repair
Electric range
Coil elements or radiant elements under a smooth glass top, with an electric oven below, all running on a dedicated 240-volt circuit.
Dual-fuel range
Gas burners on top and an electric oven below, the combination most professional-style ranges use, needing both a gas line and a 240-volt circuit.
Induction range
A glass top that heats the pan itself through copper coils and power boards, over an electric oven, with electronics doing almost all the work.
