Sharp Microwave Troubleshooting. If you’re looking to repair your Sharp microwave, we’ve got the ultimate guide available. This article serves as a troubleshooting guide that will walk you through identifying potential problems and offer a few tips.
Sharp microwaves use a computerized system to monitor cooking time, control heating elements within the oven, operate the carousel with its own integrity test.
Respond to commands from the user on how to cook their favorite food. Should any errors occur within this process it will interfere with your ability to heat or cook your food as before.
Sharp Microwave Troubleshooting
In this article, we discuss how to troubleshoot some problems with sharp microwaves.
Sharp Microwave Will Not Work
Thermo protectors in most microwaves automatically cut off the power if the microwave overheats.
Testing to make sure this is functional can be done by using a multimeter to verify continuity. If not, and the Thermo protector cannot be reset, then it must be replaced.
A line fuse may blow if too much current passes through the microwave circuit. A blown line fuse prevents the microwave from working.
A multimeter can be used to check for continuity on the line fuse. If there is no continuity, replace the fuse.
Additionally, you should investigate and resolve the problem that caused the fuse to blow.
The underlying problem hasn’t been adequately handled when you initially replaced it with a new one before proceeding with normal day-to-day operations. If you don’t resolve it, then another fuse will blow as well.
Sharp Microwave Will Not Heat
The critical magnetron generates the high-frequency waves that cook the food.
A burned-out gasket on the inside of a magnetron can dam up the microwaves so they are not able to function properly which leads to food being cooked unevenly and possibly undercooked or overcooked.
This is why you must be extremely careful when changing a gasket on your microwave, even if it’s causing issues with operation.
Thermal fuses interrupt power to the microwave when it overheats. To test if the thermal fuse has blown, use a multimeter to test it for continuity.
Blown fuses are hard to detect visually and they can’t be reset so make sure you’re actually measuring continuity.
If your multimeter reads 0 ohms with the switch in continuity mode, then that means you have a blown fuse and you need to replace it.
Sharp Microwave Arcs Or Sparks
On the rack support, one or more paint portions may have chipped away. Inspect the rack supports for any burnt patches or obvious cracks that can be identified by a glimmer of aluminum showing through.
These sections should ideally be repainted with microwave-safe paint, and if not replace entirely for safety reasons.
The waveguide cover might be damaged and the metal body behind it is exposed. If this is the case, you’ll need to remove the back cover using a putty knife and then replace the fragile metal piece.
Sharp Microwave Door Will Not Open
The door handle actuator is connected between the door open button and the door latch assembly.
The door handle acts as not only the button to let people open your office doors by shaking them, but also as a sensor that detects when people have actually decided that they want to go through with actually opening the door to your office. If this sensor breaks from wear and tear, you can replace it.
A door hook engages with a door latch to keep a door closed during operation. Since it is made of plastic, the door hook can wear out if used repeatedly.
When the plastic wears or breaks, the door will not open properly. If this happens, it’s important to be aware that replacing it is important not just for safety and security reasons, but also because leaving your garage or shed unsecured could result in things being stolen.
Sharp Microwave Makes Noise
Remove the fan motor from the microwave and turn the blades by hand to find out if it is faulty. If the blades do not turn freely, replace the fan motor.
If the blades do turn freely, use a multimeter to test for incoming power into the motor and for continuity across its terminals. If it has power but won’t run, replace it. If it doesn’t have continuity, replace it.
The microwave stirrer is a metal blade that rotates in circles slowly inside the microwave. As it turns, it deflects the microwaves around at random and messy intervals.
The best way to determine whether this spinning motor will stop working is to check to make sure it has the proper voltage. If it does but still grinds or won’t spin, then simply replace the damaged one.
