Maytag oven Model# MGR8875WS1 door will not completely close. At first it would be closed then open slightly (oven light would come on) while pre-heating. We would push the door back in and it would stay closed. We would have to do this several times until the set temperature was reached. Once the set temperature was reached the door would stay closed enough for the light not to come on but the temperature would sometimes be 100 degrees below what was set. I replaced both hinges with no change then I replaced the door gasket/seal. After replacing the gasket, the door will not close at all. Any ideas anyone?
