We’ve been using this double oven for quite some time with no problems. About 2 months ago, we started getting error code "PF" and the oven would shut off and turn back on. At first, it was infrequent and a simple press of the Upper Oven off button would reset the oven. Now, when we try and bake/roast something, it may reset 3 or 4 times in a one hour cycle. This is obviously a Power Failure alert but a visual inspection shows all wires still intact. Is this a a whole control board replacement fix or something easier? My wife will note that that the numeric degrees are lit more dimly than before but that seems indicative of an impending power failure.
Thanks for the help.
