LG 3B74133Q Microwave Time Delay Fuse – Genuine OEM Replacement Part

The LG 3B74133Q Microwave Time Delay Fuse is a genuine OEM replacement part designed to protect your microwave from electrical surges and prevent overheating. Available at Appliance Kingdom, this fuse ensures reliable performance, restores safe operation, and extends the lifespan of your LG microwave. It is compatible with select LG microwave models, so always verify your model number before purchase.

Function & Importance

The time delay fuse plays a critical role in your microwave’s operation. It temporarily allows surges of current when the appliance starts while preventing excessive current flow that could damage internal components. By doing so, it safeguards the magnetron, control board, and other vital parts. Without a functioning fuse, your microwave may fail to operate or risk permanent electrical damage.

Symptoms That Indicate Replacement

Your microwave may require a new 3B74133Q fuse if you notice:

  • Microwave fails to start or operate

  • Intermittent operation or sudden power loss

  • Visible blown fuse or burn marks inside the fuse holder

  • Microwave stops mid-cycle without error codes

Replacing the fuse promptly restores safe operation and prevents further damage to expensive components.
