Time Delay Fuse
Genuine Lg part
By: Lg
Part Number: 3B74133Q

The Time Delay Fuse is an OEM part for LG microwaves. This fuse provides a safety mechanism by delaying the flow of electricity, protecting the microwave's electrical components from power surges and ensuring the appliance operates safely. It helps to prevent immediate damage in the event of a power surge or electrical fault, thus prolonging the lifespan of the microwave.

Over time, the time delay fuse can become damaged due to electrical surges, wear and tear, or faulty connections. If the fuse blows, it can disrupt the microwave’s ability to function correctly.

Symptoms of a bad time delay fuse include:

  • The microwave not turning on
  • No response from the microwave control panel
  • The microwave stopping unexpectedly during operation
  • Electrical issues or blown circuits in the microwave

This OEM LG part is also compatible with Sears/Kenmore models.

This part fixes the following symptoms
  • Won't start

Genuine Lg part
By: Lg
Part Number: 1SBF0402418

A Tap-Tite binding-head screw used to fasten appliance panels and components where a self-tapping metal thread is required. Replaces missing or damaged fasteners to restore secure assembly and reduce vibration or rattling. What it does:

  • Commonly used where stripped, missing, or broken screws cause rattling, misalignment, or parts that won't stay attached.
  • Compatible with standard screwdrivers or nut drivers sized to the binding-head.
What's included: One Tap-Tite binding-head screw Install notes:
  • Disconnect power and unplug the appliance before working on it.
  • Use the correct driver bit to avoid cam-out or head damage.
  • Start straight and apply steady pressure; avoid overtightening to prevent stripping the formed threads.
  • If the original hole is badly damaged, assess for repair or use of a larger fastener as needed.
