Gas oven not heating (igniter glows, no flame)

On glow-bar ovens the igniter is wired in series with the gas safety valve; a weak igniter can glow but not pull enough current to open the valve. The igniter current check is an electrical test. Anything involving the gas valve, regulator, orifices or gas lines is off limits: refer to a licensed gas technician.

Before you start

  • If you smell gas: do not operate switches, do not light anything, shut off the gas supply if it is safe to do so, ventilate, leave the building and call the gas utility or 911 from outside

How to test an oven RTD temperature sensor

Most electronic ovens use a platinum RTD probe, which works the opposite way to an NTC: resistance rises with heat. Many common sensors read about 1,080 Ω at room temperature and climb roughly 2 Ω per °F.

How to test an oven bake or broil element

Bake and broil elements are 240 V resistance heaters. A good one reads somewhere in the teens to about 40 Ω depending on wattage, and never shows continuity to its metal sheath.

How to test an infinite switch (electric surface element)

An infinite switch cycles a surface element on and off to set the heat level. Test the two line-to-element contact pairs on high and off. Also test the element itself before replacing the switch.
