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.
