What To Do If Oven Makes Noise When Heating Up

Last Updated on March 8, 2021 by

It’s normal for your oven to make humming noises when in operation, but if the noise is loud enough to bother you, there might be a problem. With convection ovens, the fan’s motor may malfunction, thus making it noisy when turned on. For gas ovens, loud pops may indicate a problem with the gas supply or the oven’s components.

For electrical appliances, its risky to try and guess the problem or solution. We advise calling your manufacturer if the warranty is still valid or a technician checks it for you. There are some instances when you don’t need to seek professional help. It’s important to rule out these instances before consulting a technician. 

If your oven has a rotisserie cooking mode, check to ensure it’s turned off. If this function is turned on and the spit is missing, your oven is prone to make a squeaking noise. Grease or muck on your ovens fan can also cause it to be noisy. Ensure you clean your oven after every use, especially if you are cooking fatty foods. Some oven brands also have temperature controls that switch between modes, thus producing some sounds. Ensure you read your manual and understand your oven before troubleshooting. You need to know how to distinguish normal noises from those brought about by a faulty oven. We researched and came up with ways to know when your oven has a problem that needs repair.

Signs That Your Oven Is Faulty And Needs Repair

Noise alone cannot be used as a parameter to tell your oven is faulty. If your oven makes noise but functions properly, it might not be a major source of concern. If your oven malfunctions and makes noise, the noise could guide you to the root of your problem. Here are a few indicators to a faulty oven:

1. Abnormally Loud Noise

A properly functioning oven makes barely noticeable humming sounds. If your oven starts buzzing or ticking abnormally, you need to call a repair technician. Loud noises are mostly an indication of a loose part, mostly the fan. If you turn on your oven and make a different loud noise, turn it off immediately and call a technician. Consult a professional early enough to avoid the risk of fire or permanently damaging your appliance.

2. Overcooked Or Undercooked Food

If your oven makes noise and your tried and tested recipes no longer give you the same result even after cooking for the same amount of time, it might be faulty. Your ovens element might be faulty, thus causing the noise. If you are using a gas oven, the igniter might be blocked or faulty, affecting how your food cooks. The temperature sensor on your oven could also be problematic, thus producing noise and causing temperature fluctuations. If you notice changes in your cooking experience, call a technician.

3. Uneven Heating

If your oven heats up unevenly and makes some noise, it could be a sign of electrical issues that may cause electric shock or a fire outbreak. If your oven heats up on some parts and not others, turn it off and call a technician.

4. Your Oven Is Old

If you have had your oven for years, then it starts making noises, it could be a sign you need a new one. A good quality oven has a lifespan of 10-15 years, which might be shortened by heavy use. If you feel your oven is old and has reached a maximum lifespan, getting a new one is a great option.

How Do I Troubleshoot A Gas Oven That’s Not Heating Up?

You can troubleshoot your gas oven without calling a repair service when it doesn’t heat up. Here are a few reasons why your gas oven won’t heat and its remedies.

1. The Electrical Circuit May Have Tripped A Circuit Breaker

Your gas oven requires electricity to operate the timer and some other components. If it has a circuit breaker and it trips, the oven will not heat up. Ensure you check the circuit breaker before attempting any other remedy.

2. Gas Supply Has Been Interrupted

Always ensure your check your gas valve before igniting to ensure it’s turned on. If for some reason, your gas supply has been cut off, the oven will not heat up.

3. Check Your Igniter For Faults

Gas ovens have an igniter that lights gas for the oven to heat up.  If the igniter is faulty, your oven will not heat up. The good news is that you can replace your igniter cheaply without needing a technician. To check if your igniter is faulty, switch off power and circuit breaker, remove racks and check the igniter for discoloration. If it looks okay, turn the power back on and check if the igniter glows. If it doesn’t glow a bright yellow or orange, it means its faulty and needs to be replaced.

How To Clean Your Oven

Cleaning your oven is easy, peasy, and should not feel like a chore. Most ovens have a nonstick coating that makes them sparkle just by wiping with a wet sponge. When using your oven, be careful not to spill food to make it easier to clean. In case of spillages, wipe off before it dries.

When you want to deep-clean your oven, remove all accessories and clean them on the sink. Wipe down the surfaces with a cloth and be careful not to put debris or water in the fan’s vent holes. You can use an oven cleaner to remove grease on corners or stubborn surfaces.


Home appliances make work easier and life better, and ovens are no exception. When you are used to making juicy steaks or baking sweet treats at home, life without an oven can be boring. That is why when you notice anything strange with your gadget, you get worried and take action. A noisy oven could be a sign of a fault and should never be ignored.

If you tried troubleshooting everything and it’s not working, contact a repair technician. With appliances, it is better to take caution early to avoid dangers. We hope this information helps you figure out what could be making your oven noisy.
