MWC21095 Microwave High Voltage Capacitor, 2100 vac, 0.95 uf
MWC21095 Microwave High Voltage Capacitor (2100VAC, 0.95µF)
The MWC21095 is a universal high voltage capacitor for microwave ovens, part of the high-voltage power supply circuit that steps up household voltage to the extreme level the magnetron needs to generate cooking power. Working alongside the high-voltage diode and transformer, this capacitor doubles the rectified voltage feeding the magnetron — it's a core piece of why a microwave can produce thousands of volts internally from a standard household outlet.
Rated 2100VAC, 0.95µF, ±3% tolerance, oval aluminum can construction with two male terminals spaced 1/4" (6.35mm) apart. Overall dimensions approximately 3.35"H (body) x 2.75"W x 2.05"D, with the terminal housing adding roughly 1.3" to the total height. Over time, the internal dielectric can break down from repeated high-voltage cycling, causing the capacitor to lose capacitance or fail outright — sometimes shorting internally. Symptoms of a failing capacitor include the microwave running (light on, turntable turning, fan running) but not heating food, a buzzing or humming noise from the high-voltage compartment, arcing or sparking sounds, or the microwave tripping a breaker shortly after starting.
Quick Answer
The MWC21095 Microwave High Voltage Capacitor fixes microwave ovens that run (light, turntable, fan all working) but don't heat food, make a buzzing or arcing sound from the high-voltage compartment, or trip the breaker shortly after starting. 2100VAC, 0.95µF, ±3%, oval, 2 male terminals (1/4"/6.35mm spacing). Retains a lethal electrical charge even after unplugging — must be properly discharged before any handling.

This is a universal component rather than a single-manufacturer part, so the specific OEM number your microwave's label references will vary by brand (GE, Whirlpool, Frigidaire, Samsung, LG, and others). This capacitor is a correct replacement for any microwave capacitor matching the 2100VAC, 0.95µF specification. If you have your original part number, contact our support team and we will verify compatibility before you order.
Compatibility
This capacitor is a universal replacement compatible with household microwave ovens across all major brands — GE, Whirlpool, Frigidaire, Samsung, LG, and others — wherever the original capacitor is rated:
- 2100VAC
- 0.95µF (or a rating within roughly 10–20% higher than your original — see FAQ)
- Oval shape with 2 male terminals, 1/4" (6.35mm) spacing
Note: Voltage rating must match your original capacitor exactly — never substitute a lower voltage rating, and don't assume a higher voltage rating is automatically safe on this component the way it is with an HVAC run capacitor, since the high-voltage diode in the circuit must also be rated to match. Capacitance (µF) has more tolerance than voltage: a modest increase over the original rating is generally acceptable, but always try to match as closely as possible. If you're unsure whether this capacitor matches your microwave's original specification, check the rating printed on your existing capacitor's can before ordering, or contact our support team for help confirming compatibility.

Installation Notes
Frequently Asked Questions
Is it really dangerous to work on this even with the microwave unplugged?
Yes, genuinely. This is one of the most dangerous repairs a person can attempt on a household appliance, because this capacitor is specifically capable of retaining a lethal electrical charge long after the microwave has lost power. Unplugging the microwave is a necessary first step, but it does not make the capacitor safe to touch on its own — proper discharge with an insulated tool, verified with a multimeter, is required every time before any contact with this component.
My microwave runs completely normally — light, turntable, fan — but food doesn't heat. Is this the capacitor?
It's one of the most common causes of exactly that symptom. Since the capacitor is part of the circuit that generates the high voltage the magnetron needs, a failed capacitor can leave every other function of the microwave working normally while the actual cooking power is missing entirely.
Can I use a capacitor with a slightly different µF rating than my original?
Some tolerance is generally acceptable here — a modest increase over your original rating, often cited as up to roughly 10-20% higher, typically works fine, since the capacitance value isn't as tightly critical to the magnetron's operation as some assume. That said, always aim to match your original rating as closely as possible, and never substitute a different voltage rating; the voltage must match your original capacitor exactly.
Should I replace the high-voltage diode at the same time?
It's worth considering. The capacitor and diode work together in the same high-voltage circuit, and a failure in one can sometimes stress or damage the other. If your capacitor failed and you're already taking the precautions needed to safely access this compartment, it may be a reasonable time to inspect or replace the diode as well, particularly if the microwave shows signs of a more significant electrical fault.
Is this a genuine OEM part?
This is a universal replacement part rather than a brand-specific OEM part. Because high voltage capacitors of this type are a standardized component defined by their electrical specifications, this capacitor is a correct replacement for any microwave's original capacitor sharing the same 2100VAC, 0.95µF rating — regardless of which brand originally installed it.
