What to do if sparks occur in Sunbeam Microwave Oven?
If you notice sparks inside your Sunbeam Microwave Oven, stop immediately. This could be due to using metallic ware or ceramic ware with metallic trimming. Do not use metallic ware for cooking (unless specified in the cooking guide) and avoid cookware with metallic trimming.
Why Sunbeam MA-6400B2 Microwave Oven seems to be operating but little heat is produced?
If your Sunbeam Microwave Oven isn't producing much heat, it could be due to a decrease in power source voltage. Contact your local electric power utility company or a qualified electrician. It also could be caused by a defective magnetron, which requires replacement.
How to increase the output power of Sunbeam MA-6400B2?
If your Sunbeam Microwave Oven's output power is too low, it could be due to low AC input voltage. Ensure you are using the microwave oven at adequate line voltage. Also, the food may simply need a longer cooking time; this isn't always a defect.
What to do if Sunbeam MA-6400B2 does not operate at all?
If your Sunbeam Microwave Oven does not operate at all and no input is accepted, the fuse may have blown. Replace the fuse. Other potential issues include a malfunction of the monitor switch (replace primary, monitor, secondary switches), a shorted contact at the primary switch (replace high voltage capacitor), a defective high voltage transformer (replace it), a defective thermostat (replace it), or a defective power supply cord (replace it).
Why Sunbeam Microwave Oven has no microwave oscillation?
If your Sunbeam Microwave Oven lamp and fan motor run, but there's no microwave oscillation, the timer motor, magnetron, high voltage transformer, high voltage capacitor, or high voltage diode could be defective. Each of these components may need replacement.
How to prevent blown fuse in Sunbeam MA-6400B2 Microwave Oven?
To prevent blown fuses or breakers when using your Sunbeam Microwave Oven, avoid using other electrical appliances at the same time.
