At a Glance

Errors related to abnormalities in lightwave ovens start with the letter F and are displayed as a number on the display.
F-3 errors can occur when there are foreign substances around the touch button panel.
Wipe off any foreign substances from the touch button panel and check again.
Other errors can indicate symptoms such as defective parts, a short circuit, communication failures, and overcurrent, so it is recommended to get an inspection by a service technician.
