Troubleshooting Guide

Before you call a repair person for your oven, check this list of possible problems and solutions.

The oven does not work properly.

Check the battery voltage. The operating voltage for the oven should be greater than 11.5V or less than 15.5V.

Make sure that the door is closed securely.

Make sure that the heating time was properly set.

Make sure that the start button is pressed. If door is open, close the door and press the start button again.

Check if the safety fuse is installed to the positive cable(near battery).

Check if the connection cable terminals are properly connected to the oven.

Improper use of the microwave stops oven operation. The Display shows Error Codes (page 14)

Food heats too slowly.

Check if the container is microwavable.

Do not put too much food in the oven at one time.

Check if the heating time was too short.

Check if the battery voltage is too low.

You see sparks or arcing.

Remove any metallic utensils, cookware, or metal ties. If using foil, use only narrow strips and allow at least 3cm between the foil and interior oven walls.

The turntable makes noises or sticks.

Clean the turntable, roller ring and oven floor.

Make sure the turntable and roller ring are positioned correctly.

Care and Cleaning

Follow these instructions to clean and care for your oven.

Keep the inside of the oven clean. Food particles and spilled liquids can stick to the oven walls, causing the oven to work less efficiently.

Wipe up spills immediately. Use a damp cloth and mild soap. Do not use harsh detergents or abrasives.

To help loosen baked on food particles or liquids, heat two cups of water (add the juice of one lemon if you desire to keep the oven fresh) in a four-cup measuring glass at High power for five minutes or until boiling. Let stand in the oven for one or two minutes.

Remove the glass tray from the oven when cleaning the oven or tray. To prevent the tray from breaking, handle it carefully and do not put it in water immediately after cooking. Wash the tray carefully in warm sudsy water or in the dishwasher.

Clean the outside surface of the oven with soap and a damp cloth. Dry with a soft cloth. To prevent damage to the operating parts of the oven, don’t let water seep into the openings.

Wash the door window with very mild soap and water. Be sure to use a soft cloth to avoid scratching.

If steam accumulates inside or outside the oven door, wipe with a soft cloth. Steam can accumulate when operating the oven in high humidity and in no way indicates microwave leakage.

Never operate the oven without food in it; this can damage the magnetron tube or glass tray. You may wish to leave a cup of water in the oven when it is not in use to prevent damage if the oven is accidentally turned on.
