Repair Instructions:

An oven burner spark electrode is used to light the gas for the bake and broil burners. The electrode, which works like a spark plug, sits next to the burner. When it receives electricity, a spark jumps from the electrode tip to the shield, igniting the gas. If the electrode is broken or worn out, the spark might not happen. You can look at the electrode assembly to see if there are any cracks in the porcelain housing or damage to the electrode tip. Remember, it's important for the range to have a proper ground and the right polarity of incoming voltage for the electrode control to detect a flame once the burner is lit. If the burner turns off after being lit, check for a proper ground and the correct polarity at the wall outlet.

Repair Instructions:

The overlay is the touchpad and buttons on the oven's control panel that allows the user to input commands. If the overlay is damaged or malfunctioning, it can prevent the oven from turning on. Some common overlay issues that can lead to the oven not powering up are cracked or pressed-in surfaces, moisture damage causing shorts, and keypad buttons that are unresponsive or sticking. If the overlay is not sending the proper electrical signals to the control board when the buttons are engaged, this can effectively disconnect the communication between the user and the oven controls. Without properly working input buttons and touch sensors, the oven control board may not receive the signals it needs to activate the oven. In addition, if there are shorts or damaged traces in the overlay circuitry, this can trip an internal fuse and disable power to the oven.

Repair Instructions:

The bake element is responsible for heating the air inside the oven cavity during normal baking and roasting modes. If the bake element is not functioning properly, it can prevent the oven from turning on in some cases. One common issue is that the bake element shorts out or develops an open circuit. This can blow a fuse or trip a safety valve on the oven's control board, preventing the oven from activating. Additionally, the bake element contains a sensor that feeds temperature information back to the control board. If that sensor is damaged, the control board may not allow the oven to turn on due to incomplete data. Furthermore, a damaged bake element that is arcing or overdrawing power can trip the main thermal cutoff switch for the entire appliance. That will interrupt all power to the oven.

The spark ignition system provides the spark needed to ignite the gas burners in a gas oven. This includes the ignition switch mounted to the oven's control panel and the ignition wire harness that runs from the switch to the igniters by the burners. If there is a problem with the spark ignition switch or wiring harness, it can prevent the oven burners from lighting, meaning the oven will not turn on. Issues like a faulty ignition switch, broken wires in the harness, shorts, or corroded connections can all interrupt the spark. Without that initial spark to light the gas, the oven will not ignite. No spark means no fire for cooking. The oven control board may also shut down the oven as a safety precaution if it senses the igniters are not working right.

Repair Instructions:

If the oven controls seem to work but the oven doesn't start heating, the igniter is usually the problem. The igniter does two main things. Firstly, it pulls electric current through the oven safety valve to open it. Secondly, it gets hot enough to glow and light the gas in the oven burner. If the igniter becomes weak, it can't open the safety valve properly. If the valve doesn't open, the oven won't heat. To see if the igniter is broken, watch it when the oven is on. If the igniter glows for over 90 seconds without lighting the gas flame, this means it's too weak to open the valve. If the igniter is weak, you should replace it. If the igniter doesn't glow at all, use a multimeter, a tool that checks if electricity can flow through something, to test the igniter for continuity. If the igniter doesn't have continuity, it should be replaced.

How to Replace Range/Stove/Oven Igniter

1. Shut off power. Locate the circuit breaker for the range and shut it off to cut power to the appliance.

One of the wires that send electricity to the oven element or igniter could be burnt out. These wires often burn out close to the source of heat. To check if a wire is burnt out, look at the wires going to the element or igniter. If a wire is burnt out, you can usually see visible signs of burning.

Repair Instructions:

Electric ranges need 240 volts of alternating current, while gas ranges need 120 volts. If your oven's display board isn't working, it might be a problem with the power supply. For a gas range, you can tell it has power if the oven light turns on and the burner sparks. For an electric range, try turning on one of the surface elements. If any of these elements work, the oven has power. If the oven doesn't have power, look for a tripped circuit breaker or blown fuses and fix them as needed.
