Microwaves draw a significant amount of power when operating, and if the circuit is already handling a heavy load, it may not be able to handle the additional demand. To fix this issue, unplug any other high-powered appliances from the same circuit and try running the microwave again.
Keep the microwave unplugged for 5-10 minutes. The waiting period allows the internal components of the microwave to reset, ensuring a clean slate when you plug the microwave back in and reprogram your desired settings. Check for any evidence of damage on the plug and outlet before plugging them back in.
To reset the microwave, unplug it or power cycle at the circuit breaker for 60 seconds.
Microwave Fuse Replacement
Replacing a microwave fuse costs between $10 and $15. This repair issue is often a simple fix, but if you plan on using an appliance repair person, your costs could increase to $50 to $100.
Be sure that the microwave is plugged in all the way. It is possible for the plug to get nudged and may just need to be plugged back in. If the microwave is plugged in and isn't receiving power, try resetting the breaker or fuse. It is possible that the microwave has tripped the breaker or blown a 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.
It's probably because you've connected too many appliances to one electric circuit. Check the peak power of the electric circuit in the kitchen. In the next paragraph, we'll tell you how. Next, check if the combined consumption of your kitchen appliances doesn't surpass the peak power.
With normal usage for an average family and good maintenance, a microwave often lasts for 7 to 8 years. If the microwave is used less frequently by a single person or a couple and is well-maintained, the lifespan can increase to up to 10 years.
Before you head to reset your circuit breaker, turn off all light switches and unplug, turn off or disconnect important appliances and devices in the area of your home that has lost power. This will prevent damage when the power is reset.
Here's how you test for this: Simply go up and down your panel trying to push each breaker in the “on” position. There should be little to no play because the breaker is already on. When you come across the tripped breaker there will be a lot of excess play. Now you're ready for the next step.
Start by turning off all the lights, appliances, and electronic devices in your home. Then, reset the main circuit breaker by switching it off and on. Afterward, turn on each circuit one at a time, and observe which one trips the breaker. Once you've identified the circuit, you can focus on narrowing down the problem.
Misset functions or broken parts are often to blame when your microwave is not heating up. Settings like Control Lock Mode, Demo Mode or power levels set too low may be preventing food from cooking, or more complex causes like a broken magnetron, door switch or high voltage diode could be the source of the problem.
Microwave repair requires extreme caution, even if you are only replacing one fuse. Microwaves use much higher voltage than other common appliances, and can cause serious injury or death if handled incorrectly. Only people experienced in electrical repair should attempt this.
Our survey results suggest that you should consider repairing the broken microwave if it's still under warranty or if it's 5 years old or less, but you'll definitely want to replace it if it's more than 5 years old.
Faulty microwave: Even the best-built microwaves only last around seven years. If the microwave is used frequently, that may be as short as four or five years. Design flaws, poor construction, and overuse can increase wear and tear on electrical components, which can result in a tripped circuit breaker.
To clear the error code from your microwave: Unplug the unit from the wall outlet or trip the circuit breaker to cut power supply to the machine. Allow the machine to remain unplugged for 10-15 seconds. Restore power to the unit.
If any buttons stop working on your microwave, it's most likely the result of a faulty control panel, membrane switch, or main control board. While they are repairable, if you have an old microwave, you should probably consider purchasing a new one instead of fixing it.
