Expert Review
If your Buffalo microwave is humming away but not actually heating anything, or it's cutting out unexpectedly, the HV capacitor is a prime suspect. It's a key part of the heating circuit. While it's a straightforward swap for a qualified engineer, remember this component stores a very high charge, so always call a professional for this job.
Installation & Maintenance
- Always disconnect mains power before any internal work.
- Capacitors hold a lethal charge; discharge safely first.
- Installation must be performed by a qualified technician.
- Ensure correct wiring for safe and reliable operation.
Frequently Asked Questions

Q: Is this part compatible with other Buffalo microwave models?
A: No, this capacitor is specifically designed for the 1800W models FB863, FB864, and FB865 only.
