If your microwave is on the fritz and needs repair, can you do it yourself? Though it may be the least expensive of all the appliances in your kitchen, a microwave oven should last an average of nine years, according to the National Association of Home Builders. This guide can help you troubleshoot and execute easy microwave repairs when needed and will also indicate when professional appliance repair is in order.
Before You Begin Repairs
While the lack of a working microwave might cause many to jump into the 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 unable to locate the manual, go to the manufacturer’s website and see if it is available as a free download kenmore appliance repair los angeles.
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 an appliance 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 appliance electrical processes.
Regular Maintenance Suggestions
Never run a microwave with no contents, and only use microwave-safe dishware. Keep the appliance plugged into a surge protector to guard the electrical components from overload. Close the microwave door gently to prevent fuses from blowing and keypad functions from misfiring. Respect the power of the appliance – it uses thousands of electrical volts for quick food preparation, and most intensive electrical repairs should be left to a trained expert.
