Gas Oven Is Not Heating Up — Causes And Solutions
Below, we have listed the possible reasons why your gas oven is not heating up and how to fix them.
1. Igniter
If your gas oven is not heating up, it is most likely because of a faulty igniter. To replace the igniter in an oven, do the following…
Step 1: Unplug the oven and shut off the gas supply.
Step 2: Put on some gloves.
Step 3: Open the oven door and remove the racks in the oven.
Step 4: Remove the screws on the bottom panel of oven close to the wall.
Step 5: Take out the bottom panel.
Step 6: Take out the screws which secure the igniter to the oven using a nut driver.
Step 7: Unplug the igniter wire connector.
Step 8: Remove the igniter from the oven.
Step 9: Get a new igniter and plug the wire connector to the other one in the oven.
Step 10: Reposition the igniter and secure it with the screws.
Step 11: Align the bottom panel and return the screws which hold it in place.
Step 12: Return the oven racks.
Step 13: Close the oven door and turn the gas supply back on.
Step 14: Plug the oven back in.
The video below will walk you through the process of replacing an oven igniter.
2. Safety Valve
If the igniter isn’t faulty but your gas oven is not heating up, you should check the safety valve next. The safety valve sends the gas needed for the oven to light. If the safety valve fails, it won’t send gas. Read this article: Oven Igniter [How To, Problems & Proven Solutions] to learn how to test and replace the safety valve in an oven.
3. Control Board
If your oven is not heating up but the igniter and safety valve aren’t faulty, the control board is most likely the cause of the problem. The control board sends voltage to the igniter and safety valve. If the igniter and safety valve don’t receive voltage, the oven will not heat up. Also read the “Oven Igniter” article in the section above to replace the control board in your oven.
Electric Oven Is Not Heating Up — Causes And Solution
Below, we have listed the possible reasons why your electric oven is not heating up and what to do about them.
1. Bake Element
If your electric oven is not heating up, the bake element is most likely the cause of the problem. Follow these steps to replace an oven bake element…
Step 1: First, unplug the oven.
Step 2: Next, get a Philips screwdriver and open the oven door.
Step 3: Take out the oven racks and set them aside.
Step 4: Use the Philips screwdriver to take out the two screws which secure the element. The screws are on the oven’s back wall.
Step 5: Pull the element forward and disconnect the wires from the terminals. Make sure the wires don’t fall through the oven when you do this.
Step 6: Test the element for continuity using a multimeter. If you don’t see a reading on the multimeter, the bake element is faulty.
Step 7: Get a new element and take it to the oven.
Step 8: Connect the wires to the terminals of the element.
Step 9: Hold the element in place with the screws.
Step 10: Return the racks and shut the oven door.
Step 11: Plug the oven back in.
The video below will show you how to replace the bake element in an oven.
2. Wires
if your electric oven is not heating up but the bake element is not faulty, you should check the wires. Make sure that the wires are properly connected to the bake element. Also inspect the wires for burns or cuts. Damaged wires could prevent your oven from heating up. If the bake element’s wires appear damaged in any way, contact a technician to fix or replace them.
3. Control Board
A faulty control board is the final reason why your electric oven is not heating up. In order for the bake element to heat, it has to receive voltage from the control board. If the control board fails, it won’t send the voltage needed for the element to operate. Read the “Oven Igniter” article in the “Gas Oven Is Not Heating Up” section above to replace the control board in your oven.
