My oven doesn't maintain a constant temperature. It heats up then drops way below temperature before it finally kicks on and heats back up. Makes cooking times alot longer. I am suspecting gas valve, and wondering if there is a way to repair it or if I have to get a new one.
ANSWER Hello Dale,
This can be caused by the temperature sensor, the control, the ignitor, or the gas valve. I would start by doing a current draw check on the ignitor. With a clamp on amp meter clamped on one of the ignitor wires, start the unit and make sure the ignitor is drawing between 3.2 to 3.6 amps of current. If the amperage draw is low, the issue will be the ignitor breaking down during high heat conditions, If the current draw is safely in range, the next suspect will be the temperature sensor. It should read about 1100O at 70°F.
