• Key benefit: Helps restore heating when diagnosis confirms the original capacitor is faulty.
• Installation ease: Match capacitance, voltage, terminals, mounting, and tolerance before installation.

Fixes These Symptoms

• Microwave runs but does not heat
• Weak or inconsistent heating
• Humming or unusual high-voltage circuit noise
• Repeated fuse failure or visible arcing after the capacitor is diagnosed as faulty

Compatible Brands

• Universal application; verify model-specific compatibility

Installation Instructions

Microwave high-voltage repairs should be performed by a qualified service technician. Unplug the appliance and follow the model-specific service manual. Dangerous voltage may remain stored in the capacitor after unplugging. Discharge and test the high-voltage circuit only with the proper equipment, never bypass door interlocks, and verify operation after installation. Do not substitute a different capacitance or a lower voltage rating.

Compatibility

Fits various models. Please verify compatibility with us before ordering. Always verify the complete appliance model number, part number, capacitance, voltage rating, frequency, tolerance, terminal layout, and mounting before purchase.
