Oven Not Heating Up? 6 Common Causes & How to Fix Them

Why it matters: You turn on your oven to prepare dinner, the lights come on, the digital display works perfectly—but the oven remains completely cold. An oven that won’t heat up disrupts meal prep, wastes time, and is one of the most common reasons homeowners call for appliance repair.

Whether you have a gas or electric range, the root cause is usually a single failed component. Because these involve high voltage (240V for electric) or live gas lines, most oven heating issues require professional diagnosis.

Here are the 6 most common reasons your oven is not heating, how to tell what’s wrong, and when it’s time to call ApplianceGo for fast, same-day repair.

1. Burned Out Bake Element (Electric Ovens)

The bake element is the thick black coil located at the very bottom of an electric oven. When functioning correctly, it glows bright red. Over time, the intense heat causes the element to blister, break, or burn out completely, resulting in a cold oven.

How to Check: Visually inspect the bottom coil. Look for blisters, white spots, pitting, or obvious physical breaks in the coil. Turn the oven on to "Bake"—if the element does not glow red within a few minutes, it has failed.
The Fix: Professional Repair Recommended. The element must be disconnected from the rear wiring (which carries lethal 240V power) and replaced with an exact OEM part.

2. Weak or Failed Igniter (Gas Ovens)

The igniter is the most common failure point in a gas oven. It has two jobs: it must get hot enough (glowing bright white/orange) to ignite the gas, and it must draw enough electrical current to signal the gas safety valve to open. As igniters age, they get "weak"—they may still glow, but they don't draw enough current to open the gas valve, leaving the oven cold.

How to Check: Turn the gas oven on. You should hear a click, see a glow from the bottom panel, and hear the "whoosh" of gas igniting within 30–60 seconds. If it glows but no gas ever releases, the igniter is too weak and must be replaced.
The Fix: Professional Repair Required. Replacing an igniter requires handling fragile components and safely working around the gas valve assembly.

3. Blown Thermal Fuse

Many modern ovens (especially wall ovens and models with a self-cleaning feature) are equipped with a thermal fuse. If the oven gets too hot—often triggered during a self-cleaning cycle—the thermal fuse will "trip" to prevent a fire. Once it trips, it cuts all power to the heating elements.

The Fix: Professional Repair Required. A technician must locate the thermal fuse (usually hidden in the back or top of the unit), test it with a multimeter for continuity, and replace it.

4. Faulty Temperature Sensor (Thermistor)

The temperature sensor is a small probe located inside the oven cavity (usually in the top rear corner). It monitors the internal temperature and tells the control board when to turn the heat on and off. If the sensor fails, the oven may over-bake, under-bake, or refuse to heat at all because the control board thinks the oven is already hot.

How to Check: Ensure the sensor probe is not touching the oven wall. If it is visibly damaged, it must be replaced.
The Fix: Professional Repair Required. The sensor must be tested with a multimeter at room temperature to ensure its resistance matches the manufacturer's specifications.

5. Broken Broil Element (Electric Ovens)

If your food is baking properly on the bottom but the top isn't browning—or if you set the oven to "Broil" and it remains cold—the top broil element has failed. Like the bake element, this coil can blister, crack, or burn out over time.

The Fix: Professional Repair Recommended. Similar to the bake element, this requires safely disconnecting the 240V component and installing a new OEM coil.

6. Failed Electronic Control Board

The control board is the brain of your oven. It contains the relays that send voltage to the bake element, broil element, or gas igniter. If a relay shorts out, the board will display the correct temperature and look like it’s working, but it won’t actually send power to the heating components.

How to Check: If the bake element, broil element, temperature sensor, and thermal fuse all test positive for continuity, the control board is the likely culprit.
The Fix: Professional Repair Required. A technician will trace the voltage directly from the board. If voltage is entering the board but not leaving it, the entire board must be replaced.

Why You Shouldn't Use the Self-Cleaning Feature

A pro tip from our technicians: Avoid the self-cleaning cycle. The self-clean cycle pushes your oven to extreme temperatures (over 900°F) for hours. This intense heat frequently blows thermal fuses, fries electronic control boards, and prematurely kills heating elements. Instead, use a specialized oven cleaner and a little elbow grease to keep your oven pristine without risking a massive repair bill.

When to Call ApplianceGo for Oven Repair

Oven repairs involve highly dangerous 240-volt electrical currents and live gas lines. For your safety and to prevent fire hazards, do not attempt to disassemble your oven's electrical or gas components.

You should call ApplianceGo if:

Your electric oven elements show visible damage, blistering, or do not glow red.
Your gas oven igniter glows but the gas never ignites (or it takes over 2 minutes to light).
The oven recently stopped heating immediately after running a self-cleaning cycle.
The oven heats, but the temperature is wildly inaccurate and burning food.
