Product description

XPARTCO Microwave High Voltage Fuse — 5KV 800mA (0.8A)

Product Description

Express Parts Direct carries this XPARTCO 5KV 800mA high voltage fuse as a value-priced replacement for Samsung microwave ovens. The HV fuse is a small but critical component in the microwave's high voltage circuit — when it blows, the microwave typically runs but produces no heat, or goes completely dead. It is one of the most common reasons a microwave suddenly stops working and one of the least expensive repairs.

This fuse is a direct replacement for Samsung part numbers DE91-70060A, DE91-70054A, DE91-70060C, and DE91-70061B. The voltage and amperage rating must match your original fuse exactly — confirm before ordering.

Quick Answer

5KV 800mA replacement for Samsung microwave HV fuses DE91-70060A, DE91-70054A, DE91-70060C, and DE91-70061B. If your microwave runs but won't heat, inspect the HV fuse first — it's the most common cause and the cheapest fix. Discharge the capacitor before opening the cabinet.

Common Symptoms This Part Fixes

  • Microwave runs (light on, turntable spins) but produces no heat
  • Microwave is completely dead — no lights, no response
  • Microwave trips the circuit breaker or blows the house fuse when started
  • Microwave stops heating mid-cycle
  • Burning smell followed by loss of heating function

Replaces Part Numbers

XP5KV08A replaces DE91-70060A, AP4232254, PS4235622, DE91-70054A, AP4232252, PS4235616, DE91-70060C, DE91-70061B, EAF36358312

Compatibility

Compatible with Samsung microwave ovens using 5KV 800mA (0.8A) high voltage fuses, including models using part numbers DE91-70060A, DE91-70054A, DE91-70060C, and DE91-70061B. The fuse rating (voltage and amperage) must match your original exactly — verify before ordering.

Key Features

  • Rated 5KV / 800mA (0.8A) — matches OEM fuse specification
  • Replaces DE91-70060A, DE91-70054A, DE91-70060C, and DE91-70061B
  • Glass fuse body with leads — direct plug-in replacement

⚠ HIGH VOLTAGE WARNING — Read Before Servicing: Microwave ovens contain a high voltage capacitor that stores a lethal charge of up to 2,100 volts even after the unit is unplugged. You must discharge the capacitor before touching any internal components. Unplug the microwave, wait at least 2 minutes, then discharge the capacitor before proceeding. If you are not comfortable working with high voltage components, have this repair performed by a qualified technician.

Frequently Asked Questions

How do I confirm this fuse fits my Samsung microwave before ordering?
Find your model number on the label inside the microwave door frame or on the back of the unit, then cross-reference it against the compatible Samsung part numbers listed above (DE91-70060A, DE91-70054A, DE91-70060C, DE91-70061B). You can also physically inspect the blown fuse — the rating is printed on the fuse body. It must read 5KV and 0.8A (or 800mA) to match this replacement.
The microwave light and turntable work but there's no heat — is this the right part?
Very likely yes. When the high voltage fuse blows, the low-voltage control circuit continues to function normally (light, display, turntable), but the high voltage circuit that powers the magnetron is dead. The result is a microwave that acts normal but produces no heat. Inspect the HV fuse first — if the glass body is blackened or the internal element is broken, replace it.
Why did my fuse blow? Will the new one blow too?
The HV fuse blows to protect the magnetron and transformer. Common causes include running the microwave empty, a failing magnetron, a shorted high voltage diode, or arcing inside the cavity. If the new fuse blows immediately after replacement, there is a deeper fault — typically the diode or magnetron — that must be diagnosed before another fuse will hold.
Is this an OEM part?
No. This is an XPARTCO aftermarket part sold as a value-priced compatible replacement. It is not manufactured by or affiliated with Samsung Electronics. If you require a genuine Samsung OEM fuse, we carry those separately.
Can I use a higher-amperage fuse if this rating isn't available?
No. Never substitute a higher-amperage fuse in a microwave high voltage circuit. The fuse is sized specifically to blow before the magnetron and transformer are damaged. Using a higher-rated fuse defeats the protection and can result in those far more expensive components burning out instead. Always use the exact rated replacement.
