Gas range oven temperature off?

A drifted or failing oven temperature sensor sends incorrect resistance values, causing the control board to over- or under-heat the oven.

Likely causes · most likely first

Range Oven Temperature Sensor

Easy DIY Part: $20–$45
Range Oven Control Board

Moderate DIY Part: $100–$220

A faulty control board may misinterpret accurate sensor readings and incorrectly cycle the gas valve, resulting in temperature errors.
Range Gas Control Valve

Hard DIY Part: $60–$130

A gas valve that does not fully open delivers less than rated BTU output, causing the oven to run cooler than the set temperature.
Range Oven Door Seal

Easy DIY Part: $20–$50

A deteriorated door seal allows heat to escape the oven cavity, requiring longer run times and causing uneven temperature distribution.
Range Bake Igniter

Moderate DIY Part: $25–$55

A weakened igniter that takes longer than normal to glow delays gas valve opening, causing irregular heating cycles and temperature fluctuations.
