Jenn-Air Oven Won’t Turn On/Off [How To Fix]

If your Jenn-Air oven won’t turn on or off, you are in the right place. In this article, we will show you how to fix these problems and more.

Jenn-Air Oven Won’t Turn On — Causes And Solutions

Below, we talk about the possible reasons why your Jenn-Air oven won’t turn on and what to do about them.

1. Power Problem

If your Jenn-Air oven won’t turn on and the display is blank, it may be because it isn’t being supplied with sufficient power. To test if your Jenn-Air oven is being supplied with sufficient power, follow the steps below…

Step 1: Get a voltmeter.

Step 2: Pull your Jenn-Air oven away from the wall.

Step 3: Go to the rear of the oven and unplug the power cord from the outlet.

Step 4: Set the voltmeter to the volts ac setting by turning the dial.

Step 5: Insert one of the voltmeter’s probes into the top hole of the electrical outlet. Be careful as you do this.

Step 6: Insert the other probe into the hole on the left.

Step 7: Note down the reading.

Step 8: Lift the probe out of the hole on the left and insert it into the one on the right.

Step 9: Note down the reading as well. Gas ovens require 120 volts to operate while electric ovens require 240 volts. If one of the readings for the outlet was far higher or lower than 60 volts for a gas oven, the outlet should be replaced. If the reading was far higher or lower than 120 volts for an electric oven each time it was tested, the outlet should be replaced.

2. Thermal Fuse

If the display of your Jenn-Air oven is blank and it won’t turn on, check the thermal fuse. If there isn’t a power problem, the thermal fuse may be faulty. The thermal fuse usual burns out when a power outage occurs or when the oven gets extremely hot. If the fuse fails, the oven won’t turn on and the display will be blank. Test the thermal fuse using a multimeter. If the fuse doesn’t have continuity, read this article: Jenn-Air Oven Is Not Working [Proven Solutions] to learn how to replace it. Also read the article in the link to replace the thermal fuse if your Jenn-Air oven won’t turn on after a power outage.

3. Control Board

If there isn’t a power problem and the fuse isn’t faulty but the oven’s display is blank, the control board is most likely faulty. Before replacing the board, make sure you have checked the fuse and power supply. Read this article: Jenn-Air Oven Control [Issues & Proven Solutions] to replace the control board in your Jenn-Air oven.

4. Bake Element

The bake element heats the oven up. If the element fails, the oven won’t turn on. If your electric Jenn-Air oven won’t turn on but the display isn’t blank, you should test the bake element. Test the element using a multimeter. If the bake element doesn’t have continuity, it should be replaced. Read this article: Jenn-Air Oven Element [Issues & Proven Solutions] to replace the bake element in your Jenn-Air oven.

5. Igniter

The igniter lights the gas sent from the safety valve in order to produce a flame. If the igniter fails, the oven won’t turn on. If your gas Jenn-Air oven won’t turn on but the display isn’t blank, you should test the igniter. Test the igniter for continuity using a multimeter. If the igniter doesn’t have continuity, it should be replaced. Read this article: Jenn-Air Oven Igniter [Issues & Proven Solutions] to replace the igniter in your Jenn-Air oven.

6. Safety Valve

Safety valves are used in Jenn-Air gas ovens. The safety valve sends gas to the igniter. If the valve fails, the igniter won’t light up. This will prevent the oven from turning on. If your gas Jenn-Air oven won’t turn on but the igniter isn’t faulty, check the safety valve. Read the “Jenn-Air Oven Igniter” article in the section above to replace the safety valve in your Jenn-Air oven.

7. Wires

If the bake element or igniter and safety valve aren’t faulty but the oven won’t turn on, check the wires next. Inspect the wire connected to the bake element or igniter and safety valve. If the wires appear burnt or damaged in any way, they may be the cause of the problem. Contact a technician to replace the wires if they are damaged.

Jenn-Air Oven Won’t Turn Off — Causes And Solutions

Below, we talk about the possible reasons why your Jenn-Air oven won’t turn off and what to do about them.

1. Bake Or Broil Element

If the bake or broil element shorts out, your Jenn-Air oven won’t turn off. To determine if your heating elements are shorted out, you will need to test them. Below, we have listed the steps you need to follow in order to test the heating elements in your Jenn-Air oven…

Step 1: Unplug the oven’s power cord or switch off the circuit breaker for safety.

Step 2: If your oven is installed to a cabinet, you will need to uninstall it. To uninstall it, first open the oven door.

Step 3: Take out the screws on the sides of the oven’s front frame using a Philips head screwdriver.

Step 4: Lift the oven out of the cabinet.

Step 5: Go to the oven’s rear and take out the screws which hold the upper and lower rear access panels in place.

Step 6: Lift the access panels off and set them aside.

Step 7: Get the multimeter.

Step 8: Turn the multimeter’s dial to the lowest setting for ohms.

Step 9: Disconnect the wires connected to the terminals of the bake element. The element is on the lower rear of the oven.

Step 10: Touch one multimeter probe to one of the element’s terminals.

Step 11: Look at the multimeter’s display then lift the probe off the terminal of the element.

Step 12: Place the probe on the other terminal and look at the multimeter’s display. If you saw a reading on the multimeter when you placed the probe on either of the terminals, the element has shorted out.

Step 13: Follow the same steps to test the broil element.

If the bake or broil element has shorted out, read the “Jenn-Air Oven Element” article in the “Jenn-Air Oven Won’t Turn On” section above to replace them.

2. Control Board

If the heating elements aren’t faulty but your Jenn-Air oven won’t turn off, the control board is faulty. The control board sends voltage to the heating elements in the oven. If the control board fails, it will keep sending voltage to the elements even after the oven has been turned off. Read the “Jenn-Air Oven Control” article in the “Jenn-Air Oven Won’t Turn On” section above to replace the control board in your Jenn-Air oven.

Jenn-Air Oven Turns Off By Itself — Causes And Solutions

Below, we have listed the possible reasons why your Jenn-Air oven turns off by itself and what to do about them.

1. Heating Element

The element in an oven is one of the major heating components. Over time, the element starts to wear out. When this happens, it will start to shut off in the baking process. To determine if the element is faulty, test it with a multimeter. If the element doesn’t have continuity, it is faulty. Read the “Jenn-Air Oven Element” article in the “Jenn-Air Oven Won’t Turn On” section above to replace you Jenn-Air oven bake element.

2. Improper Wiring

If you just had your oven installed recently, it may be improper wiring that causes it to shut off. When an oven is not installed properly, it won’t function how it’s meant to. So, if your Jenn-Air oven got installed recently and it keeps shutting off, contact a technician to check if it was properly installed.

3. Temperature Sensor Or Thermostat

In some ovens, temperature sensors are used to regulate the temperature while thermostats are used in others for this same purpose. If the sensor or thermostat fails, it could send a false signal to the control board that the oven is overheating. If the oven control thinks that the oven is overheating, it will tell the oven to shut off. Read this article: Jenn-Air Oven Temperature [How To, Issues & Solutions] to test and replace the temperature sensor in your Jenn-Air oven. Follow the steps below to replace the thermostat…
