Expert Review

If your microwave has suddenly stopped heating but the light and  turntable still work, this little diode is very likely the culprit. It's a classic symptom. For a qualified engineer, this is a quick and  simple swap that will get your Buffalo microwave back up and  running in no time, saving you a fortune on a replacement unit.

Installation & Maintenance

  • Always disconnect the microwave from the mains power first.
  • Safely discharge the high-voltage capacitor before handling.
  • Note the orientation and  connection of the old diode.
  • Installation by a qualified technician is strongly recommended.

Frequently Asked Questions

  • Q: How can I tell if my microwave's diode has failed?

    A: The most common signs are the microwave running without producing any heat, or a loud, unusual humming sound during operation.

  • Q: Will this fit any other Buffalo microwave?

    A: This part is specifically listed for the Buffalo FB862 1000W model. Please check your appliance's manual to ensure compatibility.

  • Q: Is this difficult to replace myself?

    A: Microwaves contain high-voltage components that can be dangerous even when unplugged. For safety, we always advise that parts like this are fitted by a certified engineer.

Did You Know?

  • A faulty diode is one of the most common and  easily fixable reasons for a commercial microwave to stop heating.
  • This single component is critical for converting mains voltage to the high DC voltage the magnetron needs to generate microwaves.
  • Swapping this part is a far more sustainable and  economical choice than replacing the entire appliance.
