Jenn Air wall oven model WG30100B

Thank you for reaching out.     If your Jenn Air Natural Gas wall oven’s bake ignitor isn't working even after replacing the ignitor and having the control board repaired, here are some potential causes for the issue: 1. Ignitor Connections/Wiring:  Loose or damaged wiring: Even though you installed a new bake ignitor, check that the wires connecting the ignitor to the oven are secure and undamaged. Look for any signs of frayed wires, loose connections, or corrosion in the terminals. Faulty connection to the control board: Since the control board was repaired, ensure that the bake ignitor is properly connected to the bake relay on the control board. A poor connection or miswiring could prevent the ignitor from receiving power. 2. Ignitor Voltage or Amperage Issue:  Even though you replaced the ignitor, it's essential to check if it's receiving the correct voltage. If the ignitor is not drawing enough current, it won’t glow hot enough to ignite the gas. For many gas ovens, the ignitor needs to draw around 3.2 to 3.6 amps to function correctly. You can test the amperage of the ignitor using a clamp meter. If the ignitor is not drawing the proper current, it could be due to the wrong ignitor being installed, a defective new ignitor, or insufficient power coming from the control board. 3. Oven Safety Valve:  The safety valve controls the flow of gas to the oven's burner. The ignitor has to draw enough current to open the valve. If the safety valve is faulty, even if the ignitor is glowing, the gas might not flow properly. The safety valve might be faulty or stuck in the closed position. If the safety valve is not opening, it’s possible the valve itself is malfunctioning, or the ignitor isn’t drawing enough current to trigger it. 4. Control Board/Relay Issue:  Even though the control board was repaired, there could still be an issue with the bake relay on the board. It’s possible the relay that controls the bake ignitor is still malfunctioning. If you have a multimeter, you can test the relay to see if it's functioning properly. Verify that the bake relay is receiving and sending the correct signals when the bake function is activated. If the control board isn’t sending power to the bake ignitor, it may still be defective, despite the repair. 5. Thermostat or Temperature Sensor:  Some ovens have a temperature sensor or thermostat that ensures the oven heats to the desired temperature. If the sensor is faulty, it could prevent the oven from activating the bake cycle. The temperature sensor can be tested with a multimeter for proper resistance (typically around 1000-1100 ohms at room temperature). 6. Gas Supply Issue:  Though unlikely since the broil function works, there could still be an issue with the gas supply line specifically to the bake burner. Make sure there’s no blockage or restriction in the gas line to the bake burner. Steps to Diagnose:  Check the wiring between the control board and the bake ignitor for any loose or damaged connections. Test the ignitor’s amperage with a clamp meter to ensure it's drawing sufficient current (3.2-3.6 amps). Test the oven safety valve to ensure it opens properly when the ignitor reaches the correct temperature. Test the control board relay (or have it tested) to confirm it's sending power to the ignitor. Check the temperature sensor to ensure it's functioning properly. By checking these areas, you should be able to identify the source of the problem and whether it’s an issue with the ignitor, control board, safety valve, or another component.    if you checked everything and all is good .   Your should be under  Warranty up to 1 year.
