While the lack of a working microwave might cause many to jump into the microwave repair process as soon as possible, first research the model number of the appliance. Locating the owner's manual can help when identifying parts. If you are incapable to locate the manual, go to the manufacturer's website and see if it is available as a free download.

Check to see if a blown fuse may be the origin of the problem. Fuses are designed to protect the appliance from a sudden electrical power overage. Also, check the circuit breaker powering the outlet and make sure it has not tripped. Beware of the risk of electrical shock and contact microwave repair professional if neither option offers a solution - faulty wiring may be the issue.

An important electrical microwave component, a diode, facilitates electrical flow in one direction while obstructing reverse electrical flow. Diodes may either open or become shorted, causing heat loss in both cases. Unplug the appliance and discharge the capacitor, the component which stores electrical energy, before replacing the malfunctioning diode. Otherwise, you could suffer a dangerous electrical shock.

Sparks Spotted Inside the Appliance

First, make sure the appliance is clean. Grease and food stuck to the inside walls or ceiling may create occasional sparks during a high-energy cycle. Another potential cause for sparking is a malfunctioning stirrer, the component responsible for evenly distributing power throughout. Either the belt powering the stirrer or the motor could be in need of replacement.

Open the rear exterior panel to view the interior mechanical workings. The stirrer's belt can be easily detached and examined for signs of wear and tear. If it is loose and does not retain its tension, simply slip on a brand new belt. This is one of the simplest microwave repairs to conduct. Examine the fan motor and check for a blockage before calling a repair professional - hooking up a new fan motor requires the expertise and training necessary to handle the wiring challenge.

The Mechanics are Malfunctioning

Perhaps the bulb has burned out. Refer to the manual to identify the exact location of the bulb and replace it. If it remains unlit, the main electrical board may need attention from a professional. This is also the case if the digital screen and keypad is defective.

If the microwave's turntable fails to rotate, first remove all parts and clean them thoroughly. Built-up food debris could be inhibiting the turning motion. The drive brushing, the piece the turntable sits atop, may have cracked. The turntable motor could also have failed. It is wise to let a professional with experience dismantle the appliance for replacing a drive brushing or turntable motor - many steps are involved which require an in-depth knowledge of electrical appliance processes.
