The oven is not heating or is overheating
If the air in your oven isn’t heating to the right temperature or, conversely, is overheating, your thermostat is probably out of order. It’s a device that closes contacts to let the oven heat up, and opens them when the desired temperature is reached. It’s better to leave this problem to a handyman. Have a specialist open the casing, check the state of the contacts and, if necessary, replace the defective parts.
The oven won’t heat up: causes and solutions
If the oven no longer heats properly, it’s a huge loss for the kitchen. Frozen pizza can’t cook quickly. Not to mention good roasting! Solution Wanted! Here we explain what you can do to get your oven working again.
It is not easy to detect quickly a defect in the oven. As with your car, you need to troubleshoot. And there’s a lot more to check. First of all, these are the most obvious and visible defects. For example, a severely dirty oven can affect its performance. But it can also be a signal that your oven has a serious fault, so if the tips that are described in this article did not help you, leave the repair of Bosch ovens for the professionals.
Before you start troubleshooting, make sure that the defect is not caused by visible parts.
Check the power source.
You know it? You suspect that your computer is malfunctioning, call Customer Support, and a woman or man on the phone first advises you to turn off your computer. The same goes for your oven. You won’t believe how many times this simple measure has solved the problem.
So the first thing to do is to check if the oven is properly powered. The easiest way to do this is to check the light inside the oven. If it doesn’t light up, it means it’s faulty (and needs to be retrofitted) or the power is off.
Clean the oven thoroughly
Basically, the oven has a very simple technology, which is also the reason for the long life of the household appliance. If the oven stops working properly after a short time, it may be a minor problem that you can see with the naked eye.
Dirt, plaque, and grease residue can be the reason your oven stops heating properly. As a first step, it is recommended that the oven be thoroughly cleaned first. If there is dirt on the heating element, this can ensure that heat buildup is contained. Once you’ve thoroughly cleaned the oven and removed any grease residue from the hinges, check your appliance again.
If the oven works again, this was only a secondary issue. If there is still a defect, it may be due to something else entirely.
A faulty oven lamp socket can also be the reason why the oven suddenly stops heating properly.
Bent hinges cause a faulty contact. Sophisticated technology receives a false signal that the door is not locked.
Some may think this is silly, but it is not. If the oven door is not closed, it won’t heat up either. These are simple safety rules.
Oven Temperature Incorrect — Electric Range Troubleshooting
Pay attention to the sensor that indicates whether the oven door is closed properly. When you turn on any program, it triggers only if the door is not fully closed or simply opened at all.
You need to open the oven, check if everything is okay, if necessary, remove the obstruction. The sensor works, so the problem is not, then move on to the next step.
The convection fan could fail, which could also cause the oven not to heat up
This fan helps to distribute the heat over the entire area of the oven. Food cooks evenly. If it fails, the cooking will suffer. It can lead to the fact that there is no heat in the oven.
This must be checked by all means. It doesn’t take much effort. You need to remove the bottom of the oven, underneath you will see the fan.
Afterwards use your finger to turn the propeller blades. If it turns freely and doesn’t stick, there’s nothing wrong with the fan. Then screw the lower part back on. Then this is not the case, you need to look for the problem further.
For this action, special tools must be on hand. Check the safety thermostat, use a multimeter to do this. It has to be set in the ohmmeter position.
This sensor is built in here for a reason. The safety thermostat is used to prevent the oven from overheating. If this happens, it will simply fail, but it can also be a life-threatening situation.
Need to find out if the sensor may have just disconnected, in which case the oven will stop heating automatically. It’s behind the back of the oven. Once it is found, you must use a multimeter to check the terminals of the appliance.
If the thermostat is working, you will see some readings. It’s not the oven not heating that’s the problem. No values can be seen, this may be the cause of the breakdown.
Fix the glass plate damage
Glass or glass plates may be the main reason why the oven stops heating properly. Because damage to the glass allows heat to escape and distribute around the room, but not inside the oven. If the oven has a damaged glass plate, it needs to be replaced (or replaced).
Check the temperature probe
If the temperature sensor is defective, the control board does not get a message if the set temperature has already been reached. Check the working temperature sensor with a multimeter.
Check the control board
The control panel is the brain of your oven. It might also be damaged. For example, if there are black dots on it, it means that your unit no longer has heating cables. You can usually get a suitable replacement part from the manufacturer.
Tip: A multimeter will help you troubleshoot. Make sure you can also see the area in ohms.
Look at the heating elements
The heating elements may be faulty. There are many sites on the internet that offer heating elements for your oven as replacement parts. Of course, an original part is always better, but it is usually expensive.
Cooking depends on it. When the oven temperature stops heating up, one of the resistors may have failed.
It takes a long time to test the oven at this stage. Switch on all the programs in the oven one after the other. After each, put your hand to the resistor, if there is heat, then everything is working properly. You have to wait for the oven to cool down completely each time and then start the next program.
The requested intensity of each program affects the oven’s performance. It can happen that some functions work properly and others have a resistance failure.
If you haven’t figured out what the malfunction or defect is yet, it could also be the cause of improper oven heating:
Function switch is defective.
Faulty air circulation fan.
If all these possibilities still do not allow you to determine the fault, it means that there is another defect in the device. In this case it is advisable to contact a technician or contact the manufacturer. Both can usually give you an estimate of the cost after inspection. It is up to you to decide whether you want to have your oven repaired or buy a new one.
It may be better to buy a new one at once?
In some cases, it’s cheaper to buy a new device than to repair an old one. Also, older models use a lot more electricity than newer ovens, which means you can regularly save money by buying a new.

This is how you can tell if the oven is heating properly.
To find out if your oven reaches the set temperature, use a sugar trick. And it works like this:
Meanwhile, make two bowls of aluminum foil
Fill both bowls with about 3 tablespoons of sugar
Place the sugar on the table. Turn off the oven for 15 minutes
When the time is up, remove the bowl and set it aside
Place the second aluminum bowl in the appliance
Set this one aside as well. Sugar in the oven for 15 minutes
Compare two sugar bowls: sugar caramelizes at 186° C. Thus, the first bowl should be white, while the second has already taken on a brownish color. Otherwise your oven will not reach the desired temperature.
And last but not least, a review. with specialized knowledge only, please
Craftsmen familiar with electricity, especially high voltage current, can use the proper devices to find faults. But remember that messing with your oven can also be dangerous, especially if it is not unplugged.
Thus, failures in the heating of the electric oven are very productive, although not frequent. Once the cause of the malfunction has been determined, which is most often due to a malfunction of an item such as a resistor, thermostat or door lock, a protocol for replacing it should be followed. If the problem is more serious and concerns the electrical supply to the household appliance, do not hesitate to contact a qualified professional to get a guarantee of a flawless and reliable installation.
If the user does not want to perform the repair himself. Then the best solution would be to call a specialist at home. Some service centers do not carry out a visit to the house to the client. Turning to such organizations, we advise against, t.к. Removing and installing the oven will take a long time. In this case, the device may be damaged, which is extremely detrimental to further recovery.
The best solution. is to apply to a specialized service center, which is accredited by the manufacturer of household appliances. Such an organization will be able to maximize the quality of repair and use original spare parts. Turning to private craftsmen or multi-profile services makes sense only if it is impossible to work with an official organization.
How to Calibrate the Temperature in the Oven
An oven that doesn’t show the right temperature can put a lot of good cooks off. If your cakes seem runny even though you’ve baked them for the required amount of time, or your fried chicken is dry and overcooked, even if you’ve followed the instructions, your oven temperature can be turned off.

To properly understand why the oven does not work, you need to understand what principle it works.
Principle of operation of gas oven
Simply press the ignition button to start the modern gas oven.
Gas enters the burner, which from a spark forms a flame, thanks to the automatic ignition device. The gas intensity can be controlled by the rotary knob. And there’s also a block when the gas doesn’t come on if the fire goes out.
But your model may have another principle. manual ignition with matches.
When you see that the flame doesn’t go out, you can adjust the temperature and wait for the oven to heat up.
Signs you can tell if the oven in your gas stove isn’t working:
- The gas is not supplied to the burner.
- It takes longer to cook food than usual.
- Food burns or remains soggy.
- The flame goes out.
- The fire gets smaller for no reason.
Important. If the oven stops working because the fire suddenly goes out, check for gas leaks. You’re more likely to smell something bad. If there is a leak, shut off the gas supply and call the service. Life-threatening gas leakage.
If it is not a leak, you can try and repair the damage yourself.
How an electric oven works
An electric oven has a similar structure to a gas oven. It is also intended for cooking.
Only the electric oven has two heating elements of solid steel. They are needed to maintain the temperature and bake the food evenly.
The model may have more than two heating elements.
In this case, if the electric oven does not work due to a failure of the heating element, then you need to know which one you have, since they differ. It could be a difference in size, power, number of circuits, purpose.
Signs by which you can understand that there is something wrong with the oven:
- It does not turn on. And the backlight with indicators doesn’t work either.
- Small heaters with working light and indicators.
- No heat at all, but the backlight and indicators work.
- The heaters turn off automatically.

Electric Ovens
Electric ovens are increasingly replacing their gas counterparts. Well-brand catalogs include both built-in and free-standing models. The first option requires installation work, but creates an additional work surface. Freestanding models are more compact and can be rearranged at any time, or taken with you to the cottage. The design of the working chamber of electric ovens is the inner and outer casing, between which there is thermal insulation.
The functionality of electric ovens is quite broad. New models have defrosting modes, a steam cooking function, a built-in microwave and a steam cooker. Instead of an open flame, electric ovens use heating elements both above and below the oven. Most models have a grill. Heating elements can be combined in the desired way to provide the desired cooking mode. The classic set of heating modes. Top, bottom, combination and grill. Electric ovens have mechanical, electronic, or combined control. Safe operation of electric ovens provides laminated glass on the door, tangential cooling surfaces, telescopic rails.
How to check whether the thermostat is working properly
Why is it important for your gas oven thermostat to work properly and give you the most accurate results?? The accuracy of your thermostat directly affects the quality and taste of your food. With a broken thermostat you will not achieve the desired result, so if your food after cooking for a long time remains raw, you should contact our shop and order the oven repair at home or in any other. In order to avoid a cheat among unfair masters we’ll tell you how to check the serviceability of the thermostat of the gas stove.
Self-diagnosis of the thermostat of the gas oven shows not exact values. 5 degrees, but in general, it will help to identify whether the thermostat requires replacement. However, such deviations are characteristic and allowable for older ovens, so we will not pay attention.
Modern ovens come in two versions: independent and stand-alone. The former have a separate control system that is not linked to other appliances. Independent ovens are combined with a hob and have a joint control system. Electric ovens use heating elements to generate heat.
As a rule, it is the top, bottom heating or combined mode. The presence of the grill function greatly expands the possibilities for cooking. Equipped with a convection mode provides even heating of the food. The oven’s oven temperature is controlled on the control panel. At the same time setting the temperature and cooking time by electronic or electromechanical control. Modern models are equipped with additional functions of microwave, steam cooking.
