Some common problems that require microwave/microwave oven repairs:

• Why is my microwave not heating?
• Why is my device sparking?
• The microwave turntable does not rotate?
• Microwave does not turn on?
• Microwave is not functioning?
• Microwave starts but programs don’t operate?
• Grill function not working?
• Digital display and buttons are unresponsive?
• Device makes continuous noise?
• Door is broken or does not close properly?
• Door is locked and cannot be opened?
• Fan not operating?
• Touchscreen shows error and doesn’t work?

Causes of Microwave Sparking Your device might have a faulty magnetron lamp or contain metal inside. Remember not to use metal containers inside the microwave. If the mica sheet (heat-resistant sheet) needs replacement, it may cause sparking.

Reasons for Microwave Not Heating 1_ Magnetron Lamp The magnetron lamp is a key microwave component responsible for heating food. It emits electrons and a high-frequency magnetic field to agitate positive and negative poles in food, thus heating it. The magnetron lamp was first invented by Albert Hull. Your device may have a faulty magnetron lamp causing the heating problem.

2_Diode or High Voltage Capacitor: If either part malfunctions, your microwave will not heat. The diode (with 200,000 volts tolerance) combines current from the capacitor to the transformer coil, forming an oscillator circuit. Failure of either component results in no heating.

3_Electronic Board: Power fluctuations or burnout of parts on the device board can cause the microwave to stop heating or working.

4_Microwave Fuse: The fuse is a protective component. If damaged, it leads to no heating.

5_Microwave High Voltage Transformer: The transformer increases electricity from 220 to 20,000 volts. A problem in this part stops heating.

Important Tips When Using Sigma Microwave:

• Do not use metal containers inside.
• Prefer transparent, plain ceramic dishes without gold or silver edges.
• Use a cover for heating food to preserve food quality and prevent grease buildup.

Things to Consider When Buying a Microwave Nowadays, various ovens, microwaves, solardoms, built-in, and countertop ovens are available in the market. Tasteful customers prioritize quality and authenticity. Countertop microwaves are cheaper than built-in models. For cooking large quantities, use microwaves with high wattage. Maximum power is usually 600 watts, but some models reach 1400 watts. Size and capacity are important. Your microwave should effectively perform three main functions: cooking, defrosting, and heating refrigerated food. These should be your priorities before considering other cooking programs.

Common Questions and Concerns About Using a Microwave:

• Can vegetables and fruits be microwaved?
• How many times per day can we use the microwave?
• How to cook eggs in the microwave?
• How to cook fish and shrimp with soft meat texture?
• Does microwave usage cause cancer?
• How dangerous are microwave emissions?
• To what extent does microwave use affect health?
• Can children’s food be microwaved?
