FACING AN OVEN PROBLEM AT HOME ?

A circuit breaker is essentially designed to prevent electrical wires from getting overheated. However, there’s only so much a circuit breaker can handle, and if the power generated exceeds its capacity, the breaker switches itself off to mitigate any fire hazard. Remember, being on a separate power outlet doesn’t necessarily mean the various home appliances have their own dedicated circuits.

Probable Reasons Why Your Circuit Breaker is Tripping

Before we get to the topic of why your oven is tripping the circuit breaker, it pays to understand the basics a bit. The following are the four:

Circuit Overload

Circuit overload happens when the plugged-in device seeks more electricity amperage than the circuit’s supply rating. As aforementioned, this scenario could occur if multiple devices are being simultaneously handled by the electric circuit. Redistributing load helps remedy this occurrence.

Short Circuiting

A circuit shorts when the insulated part of a particular wire comes in physical contact with another wire, causing a surge in amperage in the circuit, and tripping the circuit breaker instantaneously. Such short circuits could happen if the wiring in your household has become old or degraded with age, which may lead to cracks or frays.

Appliance Problems

Your misbehaving oven falls in this category. In this case, a particular appliance could be drawing excessive electricity, probably courtesy an internal defect or malfunction. For instance, a specific internal component of an appliance, such as a microwave or an air conditioning unit, may have undergone significant wear and tear and that could be forcing the unit to draw more power than normal for optimal performance. In such cases, the trouble-causing appliance must be disconnected and repaired before being put to work again.

Ground Fault

Ground faults occur when a circuit’s hot wire comes in contact with a metal component or wire. This is pretty similar to a short circuit – the exception being the fault in this case lies outside the wire and not within.

Remedy

Dedicated Circuit

An oven seldom functions smoothly on a shared electric circuit. Generally, the appliance takes up close to 12 amps and requires a dedicated 20-amp breaker setup. However, if you cannot for some reason have a dedicated oven circuit, then make sure you plug out or switch off all the other appliances on the shared circuit whenever you turn the oven on. But that’s a fairly laborious process, which means you are better off setting up a dedicated circuit breaker instead. There are service providers who can help you with the installation.

Preheating

Frequently used ovens are unlikely to trip the breaker. The ones that aren’t used in a while are likely to cause the issue, and there’s a good reason why is that the case. When an oven has been kept idle for quite some time and suddenly put to use, the sudden electrical surge the circuit experiences as a result causes the tripping to happen. Therefore, when you’re turning on the oven after a long time, don’t start with the highest temperature. Start at 50 degree Celsius and let the oven warm up. And with every stage, increase the temperature until you’ve reached your ideal temperature settings. People who use their ovens as a routine need not resort to such measures.

Helpful tips for handling your oven

As aforementioned, there could be multiple things relating to the oven that may contribute to the tripping issue.

There are quite a few other things that may have caused the electricity to trip, but the above are the top three suspects. This diagnosis method is basically a trial-and-error approach that narrows down on the real problem. If you’ve got sufficient professional experience handling such electric components, you may perform the diagnosis by yourself. But if you have even a minor hesitation, seek professional assistance.

Circuit Overload

First and foremost, you shall start with checking circuit problems, and you’ll need a reliable technician to do that. The technician would find out if the circuit has multiple appliances connected in tandem with the electric oven. In case that’s true, you must disconnect all the appliances and later switch on only the oven. The tripping should no longer happen.

However, if the circuit has only the oven on-board, then things such as the power load the circuit takes whenever the oven is turned on, and circuit breaker fault or circuit wiring problem could be inspected. If the excessive power load is the cause, then the circuit would need an upgrade. Relevant upgrades would be required in case of an impaired circuit breaker or wire too.

Oven Wiring/Power Plug Issue

The technician may assess the current passing through when the electric oven is switched off. Normally, the reading must be zero. In case the current measurement figure is more than 0.3A, it means the oven wiring is faulty.

Oven Component Issue

If you believe there’s something within the oven that’s inflicting trouble, simply connect only the oven to the circuit breaker. And then turn the oven on at a minimum temperature. If there’s no immediate electricity tripping, it means the fuse that the oven’s plugged into is not shorting.

Increase the oven’s temperature incrementally and when the highest temperature is being reached and the electricity trips, the problem is likely with a heating element. A fresh element would be needed to address this problem.

OVEN COMMON ISSUES

Heating Issues

Heating element broken
Every oven have different number of heating elements depending on brands and models. When a heating element is working properly, it should glow red when the oven is switched on. For most ovens, only the top heating element is visible as the bottom heating element is embedded below the bottom casing of the oven.

No incoming power
There is no power supplied to the heating element and this may be due to faulty electrical wires from the wall socket or the oven itself. Usually when there is no incoming power, other auxiliary functions (i.e. light and fan) of the oven will not be able to work as well.

Thermal fuse faulty
This problem is usually caused by prolonged usage of the oven. In general, ovens should not be used for more than 2 hours continuously without having any breaks in between. The thermal fuses are used as a safety component to prevent overheating. As such, when the thermal fuses are faulty, there is a break in power supply to the heating element.

Selector switch faulty
When the selector switch is faulty, the power connection to the heating element is broken. This problem may be due to physical wear and tear of the connection surfaces in the selector switch.

Thermostat faulty
The thermostat controls the temperature of the oven and when it is faulty, it will not be able to regulate the temperature of the heating element.

Timer faulty
Some ovens are designed to be controlled by the timer. When the timer is faulty, no power can be supplied to the whole oven.

PCB failure (Electronic ovens only)
This is the least likely to happen and when it does, only the oven manufacturer has the correct parts to replace.

Top / Bottom heating element broken
This will cause the oven to heat up only at half the heating capacity. As such, the oven will not be hot enough.

Thermostat faulty
When the heating thermostat is faulty, it is unable to monitor and feedback the temperature accurately. This will result in the heating element being cut off too early before the temperature reaches the pre-set value.

Poor connection
The wires in the oven may be worn out over time depending on the usage of the oven. This is not very common but when it happens, the connection may become loose and thus, causing the heating element not to heat properly.

Top / Bottom heating element broken
This is very obvious when the food is only cooked on either the top or bottom side.

Thermostat faulty
The heating thermostat is faulty and is unable to control the temperature of the oven accurately.

Internal fan faulty
This will cause the heat dispersion in the oven to be poor and as a result, some parts of the food will not be as cooked or even burnt.

Temperature Control Issues

Thermostat faulty
This is the most common reason why the oven is overheating. The heating thermostat is not regulating the temperature of the oven and thus causing the heating element to continue heating even when it passes the pre-set temperature.

Main thermal fuse faulty
The main thermal fuse is a safety component meant to cut off the heating element when the temperature goes over a certain temperature.

Heating element failing
This is due to physical wear and tear of the heating element. It usually happens only after many years of high frequency usage.

Wrong oven setting
This is also a possible reason especially for those using the oven to cook. Check out some of the oven settings explained in this article.

Electronic Issues

No incoming power
The power supply from the wall socket might be faulty.

Main thermal fuse faulty
The main thermal fuse is a safety component in the oven meant to cut off the power when the oven overheats. If the oven main thermal fuse is faulty, it may cause the power supply to the oven to be cut off.

Selector switch faulty
The selector switch might be faulty thus not being able to distribute the power supply to the rest of the oven.

Bulb blown
This is the most straightforward and common reason for the oven to have no light.

Selector switch faulty
The selector switch may sometimes be burnt due to high current flow and as a result, breaking the power supply to the light bulb.

Oven fan faulty
This may be due to physical wear and tear.

Selector switch faulty
The selector switch may sometimes be burnt due to high current flow and as a result, breaking the power supply to the fan.

Foreign object blocking fan
This may happen when the fan / heating element mounting becomes loose and blocks the fan.

Oven timer faulty
Some ovens are timer controlled so when the timer is faulty, the whole oven will not be able to turn on.

Earth leakage
Ovens will trip if not used often as there may be an earth leakage. The leakage is usually from the heating element.

Component short-circuit
A component in the oven might be shorted and thus causing the oven to be shorted.

Broken wire
The wires in the oven may sometimes get burnt due to the high current drawn. These broken wires may cause the oven to be shorted.

Overloading
The wall socket may be overloaded if many appliances are connected to it together with the often. This will usually cause a high current surge and trip the whole house.
