An experienced Engineer will understand the impact of low insulation across electronic circuitry. When inspecting an appliance for this type of problem, I'm going to test the appliance insulation before any other physical test...
On testing this oven for insulation resistance, I proved myself right! The insulation resistance was so low, it was almost disconnecting the circuit breaker...
After further tests, I diagnosed the problem was within the base element. The base element was replaced in this Whirlpool oven. The oven successfully passed an insulation and function test thereafter....Job done.
If your Whirlpool oven is behaving in a similar way - Kingdom Appliance Care can help! To book an oven repair or to buy a spare part for your oven Call Nina in the office on 01592 303025.
Hopefully this information helps you further.
