Frigidaire oven model FGF326asf. Within the last month I've had the igniter and the control board replaced by a professional and the oven portion works fine, but the broiler keeps shutting off after 2 or 3 minutes. Prior to the installation of the new parts, the broiler worked perfectly. I contacted the place that did the repairs, and he told me that the oven door might need to be cracked open for the broiler to work properly, but it doesn't mention anything about that in the owner's manual. He also told me that there is not a separate igniter and there really aren't other parts to go bad, so I'm wondering what it could be. The broiler will turn on okay and then just randomly shut off after a few minutes. If I turn it off and on again it will do the same thing.
