Oven Not Heating Up? Common Faults and Fixes

An oven that will not heat, or that cooks unevenly and never quite gets there, throws the whole kitchen out. The cause depends a lot on whether you have an electric or gas oven, so start there. A quick warning up front: gas and mains electricity are involved, so some of these checks are for diagnosis only, not DIY repair.
Electric ovens: check the elements
Most electric ovens have a bake element at the bottom and a grill element at the top. When an element fails, it often shows visible damage: blistering, a bright spot, or a break in the coil. If the element does not glow red when the oven is on, it has likely burnt out. Elements are a common failure and a routine replacement for a technician.
Check whether the grill works but the oven does not
If the grill heats but the oven does not (or the other way around), that points to a single failed element or its wiring rather than a power problem. It is a useful clue to mention when you book a repair.
Gas ovens: the igniter
In a gas oven that will not heat, the igniter is the usual suspect. A weak or failed igniter will not get hot enough to open the gas valve, so the oven never lights. You should never attempt to work on gas components yourself. If you can smell gas, turn it off at the meter, ventilate, and call for help.
Check the thermostat and temperature
If the oven heats but runs too hot or too cold, or will not hold a steady temperature, the thermostat or temperature sensor is often the cause. An oven thermometer sitting on the shelf will quickly tell you how far off it is.
Check the clock and controls
Some ovens will not start a bake cycle if the timer or clock is set to "auto" or a delayed start. Check the display is in manual mode. It sounds simple, but it catches people out, especially after a power outage resets the clock.
When to call a professional
Elements, igniters, thermostats, sensors and control boards all need proper testing and, in the case of gas, a licensed technician. It is not worth the risk of working on them yourself.
