There is nothing more frustrating than opening your appliance to find your dinner completely ruined. If your oven burning food has become a daily occurrence—cooking things way too fast on the outside while leaving the middle raw—you are dealing with an internal temperature regulation failure.
As a domestic appliance engineer with over 38 years of experience fixing cookers across Greater Manchester, I deal with ovens running too hot every single week. In my experience, when you have an oven burning food, there are two main culprits behind the issue: a faulty main control thermostat or a door that isn’t closing and sealing properly.
In this guide, I will show you how to diagnose both issues step-by-step so you can source the exact replacement spare parts to fix it safely.
1. A Faulty Main Control Thermostat
The most frequent technical reason for your appliance overheating and your oven burning food is a broken internal control thermostat.
How an Oven Thermostat Fails
The thermostat is the brain of your cooker. Its job is to constantly monitor the air temperature inside the cavity and click the heating elements off once your desired temperature setting is reached. Over time, the thermostat’s internal sensor bulb or capillary tube can degrade or suffer an electrical short circuit. When this happens, the thermostat completely stops reading the temperature. Instead of cutting power to the elements, it allows the cooker to heat continuously, skyrocketing the internal temperature and leading to your oven burning food.
The Quick Temperature Check

- Turn your oven on to a standard baking temperature, like 150°C.
- Place an independent oven thermometer tool onto the centre shelf.
- Watch the main indicator light on your front control panel. If the light stays illuminated continuously and your independent thermometer climbs past 200°C, your thermostat has failed to cut the circuit. It is completely dead and must be replaced.
2. Oven Door Not Closing Properly and Not Sealing
The second most common cause of an oven burning food surprise is actually an unsealed or misaligned door. This might sound backward—surely a leaky door makes an oven colder? Here is why the opposite happens.
The Heat Escape Trap
When your oven door not closing properly happens, or your rubber door seal is cracked and split, hot air constantly escapes out of the top or sides of the appliance frame. The thermostat registers this sudden drop in ambient air temperature and assumes the cooker hasn’t reached its target setting yet. To compensate, it forces the heating elements to stay turned on at full blast. This creates an intense, unregulated blast of radiant heat coming directly off the element tracking vectors, which instantly results in your oven burning food and can shorten the life span of the oven heating element.
Testing Your Door Seal and Hinges

The Visual Check: Inspect the rubber gasket lining around the oven rim. If it is flat, loose, or torn, hot air is escaping out through the casing framework.
The Paper Test: Close your oven door on a simple piece of paper. Pull the paper gently. If it slides out easily without any resistance, your hinges are worn out, or your door seal is failing to compress, leaving you with an oven door not closing properly and not sealing error.
