3. TROUBLESHOOTING GUIDE
You can solve many common freezer problems easily, saving you the cost of a possible service call.
Try the suggestions below to see if you can solve the problem before calling the servicer.
Moreover, the start and stop of the operation of compressor may incur buzzing sound. The electrical
components may also cause some “clattering” and “boh” sound due to their constant connection or
disconnection. All these light sounds are normal.
If you are unable to solve a problem yourself, get in touch with customer services.
