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.

Cause 3Incoming 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 4Loose 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 5Oven 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 6Temperature Control Thermostat

The oven thermostat regulates the broiler temperature. If there is an oven broiler problem the oven thermostat might be defective. The oven thermostat has a thin copper tube attached to a slightly thicker tube which sticks into the oven. Inside this tube is a type of hydraulic fluid. As the broiler temperature rises the fluid expands which puts pressure on a small activator inside the thermostat and shuts off the heat. As the broiler cools, the pressure reduces and the activator allows the broiler to heat. The oven thermostat is difficult to test and is not repairable. If this is the cause of the problem the oven thermostat will have to be replaced.

Temperature Control Thermostat - Part # 251863 Mfg Part # WB20K8

Oven thermostat assembly. This thermostat monitors the temperature inside the oven and cycles on the heat when the oven drops below a set temperature. If the oven does not bake, or if the oven temperature is off by more than 50 degrees Fahrenheit, the oven thermostat may be defective,

Cause 7Valve 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.
