Switch the cooker off if an oven is clearly hotter than its setting. If it comes back, it needs a visit. ### Why would 120-124 appear on an AGA eR7 right after a repair? AGA's first check for this code is that the thermocouples have not been plugged into each other's places behind the user panel. Work that disturbed those plugs is worth mentioning when you book. ### Should I keep using an AGA eR7 oven that logged 120-124? It is safer not to until it is checked, since the code means a zone read as overheating. Switch the cooker off if an oven feels hotter than its setting. --- **[Read on the site: AGA eR7 oven showing error 120-124 | OvenRepair.center](https://ovenrepair.center/error-codes/aga-120-124/)** **[Book a visit with OvenRepair.center](https://ovenrepair.center/schedule/)**
