My gas oven frequently trips my GFCI outlet.
The GFCI outlet is upstream of the oven. Every outlet on that wall is on a shared circuit (I understand this is suboptimal, but I imagine there isn't a large load with just a gas oven and a Google Home plugged in).
The oven creates a lot of steam, which condenses on the backsplash. My theory is that the moisture drips down the backsplash and hits the outlet where the oven is plugged in.
When it trips, it takes 5-10 minutes until it can be reset. I believe this is because the outlet is drying out.
Interestingly, it can be reset a lot quicker if the convection fan is not used. For instance, if the GFCI trips and is reset 5 minutes later, I can turn on the oven again, but turning on the convection fan trips the GFCI. At other times, the convection fan is no problem.
Is my moisture theory correct? If so, what's the solution? Perhaps some sort of backer rod stuffed between the back of the oven and the backsplash to prevent drips from reaching the outlet?
