Some time ago, the bottom heating element of the oven burnt. I replaced it. From there, the temperature can not rise to the assigned target (350° F). It stalls at around 200 and it is very slow to reach it. I thought that the element was the culprit but the vendor rejected the return and told me that the electronic board could have burnt too and that I should check that I get 240V at the element connectors. So I borrowed a multimeter and tried various things:
The continuity test around the element is ok. I get 0V when starting the Bake function. However, the temperature slowly rises, which puzzles me since I get 0V. If I test the top element I correctly get 240V when starting the Broil function. Can I safely consider that the electronic board is the culprit and purchase a new one?
Why is the temperature still rising slowly while I read 0V around the element?
The oven is a Whirlpool model YWFE745H0FS1.
Thanks helping me understand what happens.
