I know others have had this problem, not only with the oven light flickering (which I don’t really care about), but it also makes other lights in the house flicker. This concerns me. I have a really old light that has 2 bulbs in it that are probably 100 years old, and you cannot get them anymore. We leave it on all the time in order not the stress the filaments with it repeatedly turning on and off. But those bulbs flicker in sync with the light inside the oven now. Which got me thinking, how can this affect sensitive electronics in the house? I have a LOT of sensitive electronics, including a very expensive lighting controller which isn’t made anymore. If this died, it would cost a ridiculous amount to replace. My LED bulbs don’t flicker, only incandescents (of which I have like 4 total).
Has anyone used any test equipment to see what’s going on? I have some stuff here for measuring power factor and some other things, but haven’t gotten around to looking. The good stuff I had here, I had to return to a friend that I borrowed it from a couple of months back.
Interestingly, I went through something similar awhile back when I put a generator hookup on my house. The generator I was using turned out to have 25% Total Harmonic Distortion (which wasn’t listed anywhere in the documentation). When I called the company about the lights flickering when running on generator, they told me straight out “do not run sensitive electronics on this generator.” I since have a new generator which is fine. But, I’m concerned that the same flickering thing is happening with this oven running and it might cause problems with things in the house.
I’m guessing they are using PWM to control the heating elements, which is causing this. Seems like a large capacitor would possibly fix the problem.
