If you turn the oven on and it doesn’t heat up, it could be that your oven ignitor has gone bad. You see, when the oven control is turned to bake, the ignitor turns on and starts to glow a bright orange, that is if it is working properly. When functioning correctly, the ignitor gets hot, the gas valve opens and sends gas through the burner. The ignitor lights the gas coming from the burner and the oven begins to heat.
However, if the ignitor doesn’t glow hot enough, the oven will not light and you’ll likely smell gas. Don’t worry though, the gas valve is equipped with a safety mechanism that detects a gas leak and shuts the gas valve off, if it is working properly.
Now you may have seen the ignitor glowing and thought it was just fine, but that’s not always the case. In fact, sometimes it may actually light and others it may not. These are good indications that the life of your ignitor is over.
It is easy enough to replace an oven ignitor if you know what you are doing. Just remember to shut the power off before replacing the ignitor and never touch the black-colored coil with anything. They are very fragile and oil from your hands can shorten the lifespan of the ignitor.
