Frequently Asked Questions - 58040 KORONA

How do I set the cooking time on my Korona 58040 microwave?

Turn the timer dial clockwise to the desired time (up to 30 minutes). The microwave will start automatically after setting the time.

Can I use metal containers in the microwave?

No, metal containers or aluminum foil can cause sparks and damage the microwave. Use microwave-safe glass, ceramic, or plastic containers.

How do I defrost food using my Korona 58040?

Set the power level to 'Defrost' (or a low power setting, such as 20-30% power) and enter the weight of the food. The microwave will calculate the defrosting time automatically.

What should I do if the microwave stops working?

Check the power cord and outlet. Ensure the door is fully closed. If it still does not work, reset the circuit breaker or contact KORONA customer service. Do not attempt to repair the microwave yourself.

How do I clean the interior of my Korona 58040?

Wipe the interior with a damp cloth and mild detergent. Do not use abrasive cleaners or scouring pads. For stubborn stains, heat a cup of water with lemon slices for a few minutes to loosen residue.

Is this microwave suitable for a family of four?

Yes, the 20-liter capacity is sufficient for most family meals such as reheating and cooking moderate portions.

Can I use my Korona 58040 to bake a cake?

This microwave is not designed for baking. It is best used for reheating, defrosting, and cooking simple dishes. Use a conventional oven for baking.

What does the 'child lock' feature do?

The child lock prevents accidental operation by locking the control panel. To activate, press and hold the 'Stop' button for 3 seconds until you hear a beep.

How often should I replace the turntable?

The glass turntable is durable and should only be replaced if cracked or broken. Replacement turntables are available from KORONA authorized service centers.

Why does the microwave make noise during operation?

Some noise is normal due to the fan and magnetron operation. A low hum and clicking sounds are typical. If the noise becomes unusually loud, check if the turntable is correctly placed or contact support.

short intervals. Certain molecules, e.g. water, inside the food start oscillating. The resulting friction energy transforms into heat and cooks food in a very short time. Microwaves can penetrate materials such as plastic, glass, or ceramics at almost no loss of power. The cookware is still cold while food and beverages heat up from within. It is the food/beverage that eventually makes the cookware heat up, too (thermal conduction).
