Microwave Repair Service

Microwave Not Heating

A microwave should operate quietly with only a slight humming sound. If you hear grinding, buzzing, or rattling noises, it could indicate a problem with internal components. One of the most common culprits is a defective magnetron, which can cause a high-pitched buzzing sound when it’s failing. A loose turntable motor or misaligned roller ring may also create unusual noises when rotating.Additionally, if there is loose debris, food particles, or a damaged fan blade inside the microwave, it can result in rattling or clicking sounds. If the noise persists, it’s important to get a professional microwave repair service to inspect and fix the issue before further damage occurs.

Microwave Turntable is Not Spinning

A microwave’s turntable helps ensure even cooking by rotating food while heating. If the turntable stops spinning, food may cook unevenly or take longer than usual to heat.Common causes include a broken turntable motor, which is responsible for the rotation. A worn-out or misaligned roller guide can also prevent the plate from moving smoothly.Another reason could be a damaged drive coupler—this is the small part that connects the motor to the plate. If any of these components are faulty, the microwave may still work, but it won’t heat food evenly. A professional microwave technician can replace the defective parts to restore proper functionality.

Microwave Sparking or Arcing

Seeing sparks inside your microwave can be alarming and should never be ignored. The most common cause of sparking (also known as arcing) is the presence of metal objects, such as aluminum foil, metal utensils, or food packaging with metallic elements.Another cause could be a damaged waveguide cover—this small cover inside the microwave protects the internal components from food particles and grease. If it gets burnt or cracked, sparks may appear during operation.Additionally, a burnt-out high-voltage diode or damaged rack support clips can also contribute to electrical arcing. If your microwave sparks, turn it off immediately and have a professional microwave repair specialist inspect it to prevent further damage or fire hazards.

Microwave Door Won’t Close

Microwave doors have built-in safety interlocks that prevent operation if the door isn’t securely closed. If your microwave door won’t shut properly, it may be due to a broken door latch, worn-out hinges, or misaligned switches.The most common issue is a damaged door latch, which prevents the door from fully engaging with the locking mechanism. Another possibility is that the hinges have become loose or misaligned, making it difficult to close the door completely.In some cases, a faulty door switch can cause the microwave to think the door is open even when it’s shut, preventing it from turning on. Fixing this issue requires realigning or replacing the latch or switch to ensure proper function.
