Safety first: Disconnect electrical power before servicing. Microwave ovens can retain dangerous high voltage after unplugging. Internal microwave repairs and fuse diagnosis should be performed by a qualified service technician. Never bypass a fuse or door interlock.

Restore circuit protection with this ERP replacement ceramic slow-blow fuse for compatible LG microwave ovens. A blown or incorrect fuse can leave the microwave without power or cause repeated fuse failures. This fuse is rated 20 amps and 250 volts, uses a slow-blow characteristic, and measures approximately 1-1/4 inches long by 1/4 inch in diameter. Match the appliance-specified current, voltage, size, and fast/slow-blow characteristic exactly.
