Why is my oven igniter glowing but not lighting the gas?

If the igniter glows but no flame appears, it may be too weak to open the gas valve. The igniter needs to draw a specific amount of current to signal the gas valve to open. A weak igniter will glow but not reach the necessary current threshold, preventing gas flow.

How can I test if my oven igniter is bad?

Visually inspect the igniter for cracks or damage. For a more definitive test, use a multimeter to check for continuity or resistance. A healthy igniter typically shows a resistance reading within a specified range, or lights up when power is applied, drawing appropriate current.

Is it safe to replace an oven igniter myself?

Replacing an oven igniter can be a DIY task if you follow safety precautions, including disconnecting power and gas. If you are uncomfortable working with gas appliances or electrical components, it is recommended to consult a qualified technician.
