Most Frequent Causes for Oven not heating

Cause 1Igniter

The igniter is the most commonly defective part for an oven not heating. The igniter has two main functions. First, the igniter draws electrical current through the oven safety valve to open it. Second, the igniter gets hot enough to glow and ignite the gas in the oven burner. If the igniter gets weak, it will fail to open the safety valve correctly. If the valve does not open, the oven will not heat. To determine if the igniter is defective, observe the igniter when the oven is on. If the igniter glows for more than 90 seconds without igniting the gas flame, this indicates that the igniter is too weak to open the valve. If the igniter is weak, replace it. If the igniter does not glow at all, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it.

Igniter for your GERange/Stove/Oven
Igniter - Part # 1990 Mfg Part # WB2X9154

Oven bake or broil igniter, 2.5 to 3.0 Amp. The igniter draws electrical current through the oven safety valve to open it. If the igniter glows for more than 90 seconds without igniting the gas flame, this indicates that the igniter is too weak to open the valve. (NOTE: This part is very fragile.)

Cause 2Incoming Power Problem

Electric ovens require 240 volts of alternating current. Gas ovens require 120 volts. If an oven won't turn on there could be an incoming power problem. To determine if the electrical outlet is providing sufficient voltage, use a multimeter to test the incoming power at the wall socket.

Cause 3Loose or Burnt Wire Connection

One of the wires that supply power to the oven element or igniter might be burnt out. These wires commonly burn out near the heat source. To determine if a wire has burned out, inspect the wires leading to the element or igniter. If a wire is burned out, it will often be visibly burnt.

Cause 4Oven Control Board

The oven control board has relays that send voltage to the bake and broil circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components. However, this is rarely the case. Before replacing the control board, first test all of the heating components. If you determine that all of the heating components are working properly, replace the oven control board. Since it’s not easy to test the oven control board, you will have to replace the control board if you suspect it is defective.

Cause 5Valve and Pressure Regulator

The valve and pressure regulator might be at fault. However, this is almost never the case. The valve and pressure regulator is frequently misdiagnosed—before replacing the valve and pressure regulator, first check all the more commonly defective parts.
