Why Is My Oven Not Heating Up? 6 Fixes to Try

1. Tripped Circuit Breaker or Blown Fuse

Electric ovens draw a lot of current; a brief power surge can trip the dedicated breaker without you noticing. Resetting it takes less than a minute and costs nothing.

1. Locate your home’s main electrical panel.
2. Find the breaker labeled Range, Oven, or Stove.
3. If the breaker is in the middle (tripped) position, push it firmly to OFF, then back to ON.
4. Set the oven to Bake at 350 °F and wait 10 minutes to confirm it heats.
5. If the breaker trips again immediately, stop and call a licensed electrician — there is a wiring fault that needs professional attention.

2. Faulty Bake Element (Electric Ovens)

The bake element is the coil along the oven floor that produces the majority of baking heat; when it burns out it will show visible breaks, blistering, or simply glow only in spots.

1. Unplug the oven or turn off the breaker before doing anything else.
2. Visually inspect the bake element for any cracks, holes, or burn marks.
3. Set a multimeter to the Rx1 (resistance) setting and touch one probe to each terminal of the element — a healthy element reads roughly 20–60 ohms; no reading means it has failed.
4. Remove the two mounting screws, gently pull the element forward, and disconnect the wire connectors.
5. Install the new element in reverse order, restore power, and test.

3. Defective Broil Element (Electric Ovens)

Many ovens use the broil element at the top of the cavity to assist with preheating, so a failed broil element can cause slow or incomplete heating even if the bake element looks fine.

1. Turn off power to the oven at the breaker.
2. Inspect the broil element on the ceiling of the oven cavity for the same visual damage signs as the bake element.
3. Test with a multimeter on Rx1 — an open reading (infinite resistance) confirms failure.
4. Remove the mounting screws, pull the element forward, and unplug the wire connectors.
5. Fit the new broil element, reattach wires and screws, restore power, and run a preheat cycle.

4. Weak or Cracked Igniter (Gas Ovens)

On a gas oven the igniter must draw enough current to open the gas valve; an igniter that glows but never opens the valve — or never glows at all — is the single most common reason why is my oven not heating up on gas models.

1. Turn the oven to Bake and watch through the oven window for up to 90 seconds — a healthy igniter glows bright orange and the burner lights within 60 seconds.
2. If the igniter glows a dull red for more than 90 seconds without igniting, it is too weak to open the safety valve and needs replacement.
3. Turn the oven off and allow it to cool completely.
4. Shut off the gas supply valve behind the range.
5. Remove the oven bottom panel (usually two screws), then the burner cover to expose the igniter.
6. Disconnect the igniter’s wire harness and remove the mounting screws.
7. Install the new igniter — handle the fragile ceramic tip carefully — reconnect the harness, reassemble, restore gas, and test.

5. Failed Oven Temperature Sensor (Probe)

The temperature sensor tells the control board how hot the oven actually is; a sensor that reads incorrectly causes the board to underheat or not heat the oven at all.

1. Locate the temperature sensor — it is typically a thin metal probe mounted on the back wall inside the oven cavity.
2. At room temperature (70 °F / 21 °C) the sensor should measure approximately 1,080–1,100 ohms on a multimeter set to resistance.
3. A reading far outside that range means the sensor has failed.
4. Turn off power, remove the one or two mounting screws, pull the probe forward, and unplug the connector from behind the back wall.
5. Install the new sensor, restore power, run a calibration bake cycle, and verify temperature with an oven thermometer.

Why Is My Oven Not Heating Up Even After Checking All of the Above? — Control Board or Gas Valve

If every component tests good, the electronic control board (which interprets the sensor signal and switches power to the elements or gas valve) or the gas safety valve itself may have failed.

1. Inspect the control board for obviously burnt relay contacts or scorched areas — any visible damage confirms the board needs replacement.
2. For gas ovens: confirm 120 V AC is reaching the gas valve terminals while the oven is calling for heat; if voltage is present but the valve does not open, replace the valve.
3. For electric ovens: use a multimeter to verify the control board is sending 240 V to the element terminals during a bake cycle; no voltage with a good element points to a bad board.
4. Control board and gas valve replacement are both viable DIY repairs, but involve high voltage or live gas lines — only proceed if you are confident in your skills.
