Oven Not Heating Up? Here's Why — and What to Do Next

Few things are more frustrating than an oven that refuses to heat up — especially when you've got dinner to cook. Whether you have an electric or gas oven, a heating fault is one of the most common appliance problems we repair across Birmingham and the West Midlands.

In this guide, we'll walk you through the most likely causes for an oven not heating up, what you can check safely at home, and when it's time to call in a Gas Safe registered or qualified appliance engineer.

Electric Oven Not Heating? Here's Why

1. Faulty Heating Element

The most common cause of an electric oven not heating is a blown or burnt-out heating element. You may notice the element has visible breaks, blisters or discolouration. There are usually two elements — one at the top (grill) and one at the bottom — so your oven may heat partially but not reach full temperature.

2. Faulty Thermostat or Temperature Sensor

The oven's thermostat or temperature sensor (sometimes called a thermistor) tells the heating elements when to switch on and off. If this component fails, the oven either won't reach temperature, will overheat, or will cut off too early. A faulty thermostat can be tricky to diagnose without test equipment.

3. Fan Motor Failure (Fan Ovens)

Fan-assisted ovens rely on a motor to circulate hot air evenly. If the fan motor fails, you may find the oven heats unevenly or the temperature display shows the set temperature but the food isn't cooking properly. You might also notice the fan is louder than usual or completely silent when it should be spinning.

4. Control Board Fault

Electronic control boards manage all oven functions. A fault here can cause intermittent heating, incorrect temperatures, or error codes on the display. Control board repairs require specialist diagnostics.

Gas Oven Not Heating? Here's Why

1. Faulty Igniter or Spark Generator

If your gas oven won't light at all, the igniter (also called the spark electrode) may have failed. You should hear a clicking sound when the oven is trying to ignite — if there's no click, the ignition system needs attention from a Gas Safe registered engineer.

2. Faulty Thermocouple or Flame Failure Device (FFD)

The thermocouple is a safety device that cuts the gas supply if the flame goes out. If it's faulty, it may incorrectly signal that the flame isn't present and shut off the gas — meaning the oven lights briefly then goes out. This is a common fault in older gas ovens.

3. Gas Supply Issues

Before calling an engineer, check that your gas hob and other gas appliances are working normally. If they are also failing to light, you may have an issue with your gas supply rather than the oven itself. Contact your gas supplier or National Gas Emergency Service (0800 111 999) if you suspect a supply issue or smell gas.

Simple Checks to Do at Home

• Check the circuit breaker — has it tripped? Reset it and test the oven.

• Check the oven's clock/timer — some ovens won't heat if the timer is set to 'auto' mode.

• Check for error codes on the display and note them down — they'll help diagnose the fault faster.

• For gas ovens — check other gas appliances to confirm your gas supply is working.

When to Call an Engineer in Birmingham

If basic checks don't resolve the issue — or if you have a gas oven and suspect a safety-related fault — contact a qualified engineer straight away. For gas ovens and cookers, all work must be carried out by a Gas Safe registered engineer. Attempting gas repairs yourself is dangerous and illegal.
