Loud Buzzing or Vibrating While Running

Over the Range Fan or Light Not Working

The vent fan and cooktop light are on a separate circuit and tend to fail independently of the cooking mechanism. It is typically caused by a clogged filter filled with grease and a jammed fan motor. We clean, replace, and restore extraction so that your cooktop vents properly again.

Built-In and Over-the-Range Units in Our Microwave Repair Vista, CA Work

Repair or Replace | The Honest Threshold
