Always make sure that the stove is entirely disconnected from power and gas before starting any repair work. Proper tools are required to replace this part. Please ensure the appropriate safety precautions are followed when attempting to fix any appliances. For more accurate information on how and where to install this igniter glowbar, the appropriate owner's manual and included diagrams should be referenced.As an authentic replacement part, this igniter glowbar is suitable for use on several different models of gas-powered ovens, stoves, and ranges manufactured by General Electric and Hotpoint. This is a genuine part made of high-quality, durable materials and is sold individually.

The Oven Igniter is an OEM replacement part for GE ovens, designed to ignite the bake igniter to start the heating process. This part is responsible for creating the spark that ignites the gas, providing the heat needed to cook and bake food. Over time, the oven igniter can wear out or become damaged, which can prevent the oven from heating.

Symptoms of a bad Oven Igniter include:

• The oven not heating up at all.
• The oven taking longer than normal to heat.
• Gas smell in the oven due to gas being released without ignition.
• A clicking sound without the oven igniting.

Causes of a bad igniter can include normal wear and tear over time, exposure to excessive heat or moisture, or physical damage from impact or mishandling.

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances. 

IMPORTANT: The connector plug may need to be cut off and igniter wires connected to range wires using porcelain wire connectors.
