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
