Why Is My Electric Oven Not Heating? Simple Troubleshooting Steps for Australian Homes

If your electric oven repair is needed because it isn't heating, don't panic. This is a common issue with straightforward fixes. Let's walk through practical steps to diagnose and solve the problem yourself before calling a technician. Most causes are simple and safe to check with basic tools.

Check the power supply first

In Australia, ovens run on 240V circuits. Start by checking your switchboard for the circuit breaker labeled "oven" or "cooker". If it's tripped (switch in the middle position), reset it. If it trips again immediately, there's a short circuit-call a licensed electrician. For built-in ovens, pull the appliance out carefully and ensure the power cord is fully plugged in. A loose connection here can stop all heating functions. Never attempt repairs with power on-safety comes first.

Inspect the heating element

The Heating element is the part that glows red when the oven is on. If it's damaged, the oven won't heat. Turn off power at the circuit breaker, then open the oven and visually inspect the element. Look for cracks, holes, or burn marks. If you see damage, the element needs replacing. For a more accurate test, disconnect the element's wires and use a multimeter set to ohms. A good element should read between 10-50 ohms. If it shows "OL" (infinite resistance), it's faulty. Replacing it is simple: unscrew the old one, install the new one, and reconnect the wires. Heating elements cost $50-$100 in Australia.

Test the thermostat and temperature sensor

The Thermostat controls temperature by signaling the heating element to turn on and off. If it fails, the oven might not heat at all. For older models with mechanical thermostats, disconnect the wires and use a multimeter to check continuity. A working thermostat should show low resistance. Modern ovens use digital temperature sensors instead. If the oven light works but the oven doesn't heat, the sensor might be faulty. These sensors cost $20-$40 to replace. Always unplug the oven before testing-electrical safety is non-negotiable.

Check for a blown thermal fuse

Many ovens have a Thermal fuse that blows if overheating occurs. This is a safety feature. Locate it near the heating element or on the oven's back panel. With power off, use a multimeter to test continuity. If it reads "OL", the fuse is blown. Thermal fuses are cheap ($10-$20) and easy to replace. However, if the fuse blew due to another issue (like a faulty heating element), replacing it alone won't fix the problem. Always check other components first to avoid repeated failures.

When to call a professional

If you've checked all the above and still have no heat, it's time to call a technician. Issues like a faulty Control board or damaged wiring require expert handling. In Australia, electrical work must be done by a licensed electrician. Attempting DIY repairs on complex issues can void warranties or create fire hazards. A professional will diagnose the problem and provide a quote. Typical repair costs range from $150-$300, depending on the issue. For example, control board replacements can cost $200+.

Prevent future issues

Regular maintenance keeps your oven running smoothly. Clean grease buildup monthly-excess grease can cause overheating and damage components. Check the oven's ventilation to ensure it's not blocked. Avoid slamming the door, which can damage switches or elements. Periodically inspect the power cord for fraying or wear. If you notice unusual smells or sparks, turn off the oven immediately and unplug it. These simple habits prevent most common heating problems.
