Gas range oven not heating?

A weak or failed bake igniter cannot draw enough current to open the oven gas valve, so gas never flows and no flame is established.

Likely causes · most likely first

Range Bake Igniter

Moderate DIY Part: $25–$55
Range Gas Control Valve

Hard DIY Part: $60–$130

A faulty oven gas control valve fails to open in response to the igniter signal, blocking gas flow to the bake burner.
Range Oven Temperature Sensor

Easy DIY Part: $20–$45

A failed temperature sensor sends incorrect resistance readings to the control board, causing it to misread oven temperature and abort heating.
Range Oven Control Board

Moderate DIY Part: $100–$220

A defective control board cannot send the enable signal to the gas valve or igniter circuit, preventing oven heating entirely.
Door Switch

Moderate DIY Part: $15–$35

A faulty door switch that incorrectly signals the door is open will disable the oven heating circuit as a safety interlock.
