Remove and visually inspect the fuse. When you look from the top, if you see the fusible link is intact, the fuse is good. If the fusible link is not intact, you will need a replacement fuse.
Remove the fuse. Turn on the ohmmeter to any scale that measures ohms. Put one lead on each end of the fuse. If it registers anything, then it's good. If it registers nothing, then it's bad.
The possible reasons your oven is not working may include a broken baking or broiling element, a malfunctioning spark element (spark electrode), a broken igniter, a blown fuse, an issue with the control board, or outlets not providing enough power to the oven.
Replacing a fuse is a relatively easy, do-it-yourself home task that you can tackle with a little information and some electrical home safety savvy. If your home has a fuse box, the best advice is to plan ahead and become familiar with the electrical panel and with the types of fuses it requires.
The blown fuse will be apparent because the wire element within will have melted or burned from the higher electrical current. You can also leverage diagnostic tools like a test light or a multimeter to identify the dead fuse without having to pull it out. Both devices are affordable and easy to use.
Check the circuit breaker in your fuse box. A tripped breaker could prevent power from reaching your oven. If your circuit breaker has tripped, turn the breaker back on, and check to see if your oven heats up. If it doesn't produce heat, you may need to have the issue inspected by a professional technician.
If the range or oven is receiving power but doesn't work, the unit may have its own fuse or circuit breaker assembly. This assembly is usually located under the cooktop of the range.
If the oven is receiving power, various issues could be preventing it from turning on. Common electric oven problems include a broken wire; a bad control, a bake, or broil element; or the wrong amount of power coming to the unit. Common gas oven problems include a faulty gas control, igniter, or valve.
Of course, if it's the fuse on the plug then replacing it will be simple and straightforward. Remember always discontent the oven before attempting to change the fuse and make sure you're replacing it with a matching fuse.
Firstly, visually inspect the fuse and see if the filament inside is intact or broken. A blown fuse typically has a broken filament and a black or gray discoloration around it. Secondly, if your device isn't working despite being plugged in and switched on, it's likely that the fuse has blown.
The rule of thumb is that if repair costs exceed 50% of the price to install a new oven, you should buy a new oven instead of replacing it. For example, if your oven costs $2,000 but costs $1,500 to repair, you could use that $1,500 for a new and improved oven.
Reset the Electronic Control
Turn the circuit breaker to the OFF position or remove the fuse. Wait one minute, then turn the circuit breaker back to the ON position or install the fuse to reset power to the appliance. This should reset the electronic controls on the Range or Wall Oven.
If you're fumbling with the controls on your oven and it's not responding, you likely have an electrical problem. Additionally, if you notice power fluctuations, it's also an indication that something is wrong. Corrosion, shorted-out wiring, or even high currents can be to blame.
No oven has a Reset Button. If you want to reset the unit, you can turn the circuit breaker off for 5 minutes, and turn it back on. This can be enough to reset minor glitches most of the time. Otherwise, if you still encounter power outages or you lose power randomly, this may be a sign of a bad control board.
You'll typically need either a 16 Amp fuse for single, combi, or microwave ovens, or a 32 Amp fuse for double ovens. On the flip side, if your oven uses 3kW or less, you're in luck! All you'll need is a regular plug socket with a standard 13 Amp fuse.
The first thing to check is the power supply to your appliance is working. If your gas or electricity supply is in good working order, then the most likely cause is an igniter problem for a gas oven. If you have an electric oven, then the heating element could be at fault.
Place a small amount of granulated sugar in an oven-proof dish or on a cookie sheet lined with aluminum foil. Place in oven for 15 minutes. If your oven is calibrated correctly, the sugar will melt. If your oven is running cold, the sugar will not melt.
Igniter. You'll pay $150 to $250 to repair the igniter. Igniters are crucial parts of gas ovens, as they are responsible for igniting the gas to give heat and cook your food.
Sometimes a fuse is bad but not necessarily blown. In this case, the best way to test it is with a test light or a multimeter. These are both relatively inexpensive tools and provide an easy way of checking if there's a current running through the fuse.
