GE Microwave Magnetron Parts — Models & Compatibility

Your GE microwave hums but won't heat food. That's the magnetron — the component that generates the microwaves that actually cook your meal. This WB26X23320 magnetron fits over-the-range and countertop models across GE's lineup, replacing the original part number along with AP6040604, WB27X11211, and MW-4450-21.

Is This the Right Part for Your Model?

Check your microwave's model number before ordering. For GE over-the-range units like the JVM3160 and AVM4160 series, you'll find the model plate inside the door along the left edge or on the interior cavity wall. Countertop models typically have it on the back panel. Match your full model number (including letters after the series number) against our compatibility list below.

About This Replacement Magnetron

The magnetron is your microwave's power source — it converts electrical energy into the electromagnetic waves that heat food. When it fails, you'll hear the turntable spinning and the fan running, but food stays cold. Some units throw error codes, others just hum loudly without heating. This isn't a repair you can postpone — a dead magnetron means a dead microwave. The WB26X23320 is the direct replacement for multiple GE series including the JVM3160, JNM3161, AVM4160, and CEB1590 lines. It's engineered to GE's specifications and restores full heating power.

GE Series Coverage

This magnetron covers GE's mid-2010s through early 2020s microwave lineup. The JVM3160 and AVM4160 series are particularly common — these are the 1.6 cubic foot over-the-range models sold through major retailers. If you've got a stainless steel or white JVM3160DF or an AVM4160DF variant, this is your part. The JNM3161 series uses the same magnetron in a slightly different chassis configuration.

Installation Considerations

Magnetron replacement requires discharging the high-voltage capacitor first — even unplugged, microwaves store dangerous electrical charges. If you're not comfortable working with high-voltage components, hire a tech. The job involves removing the outer cabinet, disconnecting the magnetron's wire leads, unbolting the old unit, and reversing the process with the new magnetron. Plan for 45-90 minutes if you've done appliance work before.

Why Magnetrons Fail

Magnetrons burn out from age and accumulated use cycles. Running the microwave empty accelerates failure — the magnetron needs something to absorb the energy it generates. Power surges can also damage the internal antenna or filament. Most magnetrons last 5-10 years depending on usage frequency, but heavy daily use shortens that window considerably.
