(5 Pack) XPARTCO XP5KV085A Microwave High Voltage 850mA (0.85A), 5KV Fuse
The XPARTCO XP5KV085A is a pack of 5 replacement high-voltage fuses for microwave ovens, each rated 0.85 A (850 mA) at 5 kV. Each is a glass-and-metal tube fuse that sits in the microwave's high-voltage circuit and protects it against overcurrent, so a fault such as a shorted diode or capacitor opens the fuse before it damages other components. When this fuse blows, the microwave typically stops heating or shuts down, although the lights, display, and fan can still work.
These are universal-style fuses sold by rating, not by brand, so they fit any microwave that calls for a 0.85 A, 5 kV high-voltage fuse. The 5-pack covers the repair and leaves spares for the next one. A blown fuse is usually a symptom of another failed part, so the cause should be found and fixed as part of the repair. Replacement should be done by a qualified service technician.
Quick Answer
The (5 Pack) XPARTCO XP5KV085A High Voltage Fuse is a pack of five 0.85 A, 5 kV high-voltage fuses for microwave ovens whose original fuse has blown, so the microwave won't heat. Match the rating printed on your old fuse before ordering. Classic symptom: the microwave powers on, the light and turntable work, but it does not heat food.
Common Problems This Part Fixes
- Microwave runs but does not heat
- Microwave appears dead or shuts down when started, with a blown high-voltage fuse
- High-voltage fuse open or blackened after a component failure
- Keeping a rated spare on hand for technician repairs
Cross Reference Information
Part numbers can change over a product's lifecycle as manufacturers update designs or release new appliance models. For your convenience, we've included any known superseded, alternate, or cross-reference part numbers that match this item.
Replaces Part Numbers
These fuses are sold under the following part number and rating:
XP5KV085A, 5KV 0.85A
This is a rating-based universal fuse, so there is no single manufacturer part number. Match your oven's fuse by the 0.85 A (850 mA), 5 kV rating marked on the old fuse or listed in your service manual.
Compatibility
These fuses are for microwave ovens that use a:
- 0.85 A (850 mA), 5 kV high-voltage fuse
Note: Microwaves use different fuses, and the rating must match. Some use 0.65 A, 0.7 A, 0.75 A, 0.8 A, 0.9 A, or other high-voltage ratings, and a separate low-voltage line fuse near the power cord (for example, 125 V, 20 A) is a different part. Check the rating on your old fuse or in your service manual. Contact our support team with your model number and we'll help verify before you order.

Installation Notes
Frequently Asked Questions
My microwave runs but won't heat. Is this the part I need?
A blown high-voltage fuse is one possible cause, along with a failed diode, capacitor, magnetron, or transformer. A technician can test the fuse for continuity. If it has none, replace it, and find out why it blew.
How do I know if I need a 0.9 A fuse?
Check the rating printed on your old fuse or listed in your oven's service manual. The rating must match. Other microwaves use different ratings, so contact our support team with your model number if you're unsure.
Is this the same as a microwave line fuse near the power cord?
No. A low-voltage line fuse, such as a 125 V, 20 A one, is a different part. This is a high-voltage fuse rated 0.85 A at 5 kV.
How many fuses come in this order?
Each order includes 5 fuses.
Can I install this myself?
We recommend installation by a qualified technician only. The high-voltage circuit can hold a lethal charge even when the microwave is unplugged.
