Hi Paul,
Same problem!
Isolated cooker at switch & circuit breaker.
Pulled range forward.
Removed rear mains termination access cover & noted sights of overheating at live connection(s) links.
Removed links & cleaned with emery cloth, reterminated, cover on, power on.
sorted!
Will replace links at first op!!!
I hope you as lucky.
Regards Rich C.
