We've had a recurring problem with the WFG540H0AS1 oven shutting off during baking. The oven starts normally but sometimes shuts off during the baking cycle. The oven then tries to re-lite, calls for heat, igniter sparks, but the flame doesn't come back on. This problem is intermittent and seems to happen most during longer baking times. If I press 'cancel' on the control and reset the temperature then restart the oven bake cycle, it starts after one or a few retries. We have to constantly 'baby sit' the oven to be sure it's still up to temperature.
Possibly related is the oven seems to be about 25-35 below the set temperature even when it's working. Thanks for looking.
