Oven not heating up. When you cook a meal, the oven is the heart of the operation. I am going to tell you how to know if your oven will not heat up. We will be talking about electric stoves and gas stoves.
If you are working with electrical wires, make sure you are qualified to do so. Always think about your safety before attempting something that could potentially ruin your day or worse, cause injury.
It is important to always turn off the gas (if you have one) or unplug it (if it’s electric) before doing anything involving a stove or oven.
Oven not heating up
Why isn’t my oven heating up? A gas or electric oven won’t heat when the igniter or the heating element is broken. This can happen if your oven hasn’t been cleaned regularly or if it’s old, damaged, or incorrectly installed. Both of these components will require professional repair for replacement.
Here’s a step-by-step guide to fixing the most common oven problems when the oven won’t heat.
Heating elements are defective
When an oven fails to heat, chances are the problem is linked to a burned-out heating element. Both electric ovens and gas ovens have two of these main components – one on top for baking, and one on the bottom for broiling.
The telltale sign that your heating element has failed is one you can’t miss: if it’s glowing bright red instead of producing a steady stream of heat you can sense from across the room.
If that happens then there’s no need to panic because changing an electric stove’s heating element should be easier than finding your misplaced car keys. In most cases, you won’t have any trouble at all just knowing which component needs replacing.
A burnt-out element
If the bake or broil element in your oven doesn’t glow red when you turn on the unit, it’s possibly because of a symptom known as ‘bulging.’ A symptom related to burnout is called ‘open.
If you experienced this it could mean you will need to replace your part as well as get scheduled for repair service by a company professional for qualified replacement and installation.
Some people find that their parts aren’t just burned out but rather not performing at all and so will simply replace the old with new.
An incoming power outage
It has been noted that some ovens use 240 volts of alternating current through two legs of voltage. In the event of a broken circuit breaker or a blown fuse.
The element will not receive the necessary voltage to heat up and stay in operation even if the display board is illuminated or the oven light bulbs are on.
Using a voltage meter set to “Volts AC” that reads anything between 210 and 240 volts, you can verify that the circuit breaker for your kitchen is “on”.
Oven Temperature Sensor or Bulb Not Working
Most electric ovens contain a temperature sensor that constantly monitors the oven’s temperature. It may not heat the oven properly if the temperature sensor becomes defective.
Some of these sensors have a digital display. You should check the elements and wires of a defective sensor before replacing it.
Many ovens do not use a temperature-sensing bulb but instead have a dial on their surface that controls the temperature.
You should also keep track of this dial as it can sometimes become non-functional and cause heating issues if it gets stuck in place or falls off completely.
Gas Oven Ignitor Broken
It can be hard to tell if your gas oven is having a problem since it heats so efficiently and silently.
But if you experience a gas leak, or hear any strange rattling sounds coming from it, immediately turn off the oven and locate the source of the issue.
Also, if you notice that your oven is taking longer than usual to heat up, this could indicate an issue with your heating system itself.
Try baking something on a low heat setting just to see if it heats appropriately. If it works fine, then it’s safe to conclude that there may be an internal electrical failure in your heating element or igniter that needs replacing. This should only be handled by a professional.
Thermal fuse blew
If you have one of those fancy electric ovens with elements, you sometimes might find that after a period of use, you may notice that these elements will not heat as hot anymore.
So what could be wrong? Is there something wrong with the heating elements that cause them to fail to work as well?
Well, to figure this out, many people will check what is called a thermal fuse inside the oven since this usually goes bad or wears out on its own, which prevents overheating and damages your oven.
The electronic control board
Some newer appliances are more advanced than others, and even if they were installed only recently, they might require maintenance sooner than you think.
If your oven doesn’t resemble the one you’d find in a restaurant, chances are it’s driven by an electronic control board. Essentially it controls many of the same functions as your brain (though hopefully to a lesser degree).
Things like the broil and bake functions of an electric range and the oven safety valve on a gas one.
The output relay needs a steady stream of power from that board or else the electrics won’t work properly, which is why potential customers can count on us to troubleshoot the circuit boards before any future damage takes place.
If your control does not output voltage, the repairperson can determine whether it needs to be replaced.
Bad Relays issue
One of the biggest reasons for issues in one’s oven would be faulty wires or relay switches. If your oven has multiple heating elements and fans, you could have multiple relays up to four.
They may need replacing over time, but it’s not a problem if you know how to take care of them and what the best way is to get the most life out of them. Refer to your owner’s manual for more information before accessing these parts.
