Hornos y placas: 3 artículos en AEG Repair Guide Spain.

An AEG oven that won't heat can disrupt your cooking routine and lead to expensive repair bills if you call a technician immediately. However, many heating failures have simple causes that you can diagnose and fix yourself with basic tools and a multimeter. This guide walks you through the most common reasons an AEG oven fails to reach temperature and provides step-by-step DIY repair steps. Always disconnect the oven from the mains before any inspection or repair.

1. Safety First: Disconnect Power

Before you begin any troubleshooting, ensure the oven is completely disconnected from the electrical supply. For built-in models, this means switching off the circuit breaker in your fuse box that serves the oven. For freestanding ovens, unplug the unit from the wall socket. Verify power is off using a voltage tester. Never work on a live appliance.

2. Check the Obvious: Power Supply and Settings

Sometimes the issue is not a broken component but a simple oversight. Start with these basic checks:

  • Power supply: Confirm the oven is receiving power. Check if the display lights up, the interior light works, or the fan runs. If nothing works, the problem may be a tripped circuit breaker, a blown fuse, or a faulty power cord. Reset the breaker or replace the fuse. If the cord is damaged, replace it with a compatible AEG power cord (available at MediaMarkt or Amazon.es for around €15-€25).
  • Timer or clock: Many AEG ovens require the clock to be set before the oven will heat. If the display flashes “00:00” or a timer symbol, set the clock using the user manual. On models like the AEG BPE556320M, press the “Time” button and adjust with the + / - buttons.
  • Function selector: Ensure you have selected a cooking function (e.g., “Top/Bottom Heat,” “Fan Cooking”). If the knob is in the “Off” or “Light” position, the oven won’t heat.
  • Door switch: The oven will not heat if the door is open or if the door switch is faulty. Check that the door closes properly and the switch clicks when pressed. You can test continuity with a multimeter.

3. Identify the Heating Elements

AEG ovens typically have multiple heating elements: top element, bottom element, and sometimes a rear ring element for fan-assisted cooking. If only one function fails (e.g., top heat works but bottom doesn’t), the corresponding element is likely defective. If no heat at all, the problem could be the selector switch, thermostat, or control board. For a comprehensive overview of AEG oven error codes, see AEG Oven Error Codes.

Testing a Heating Element

  1. Disconnect power and remove the element cover (usually held by screws).
  2. Visually inspect for blisters, cracks, or burn marks. A damaged element must be replaced.
  3. Use a multimeter set to ohms (Ω). Touch probes to the element terminals. A good element typically shows 20-50 Ω. If the reading is infinite (open circuit), the element is broken.
  4. Also test for grounding: touch one probe to a terminal and the other to the metal chassis. Any continuity (low resistance) means the element is shorted to ground and must be replaced.

Replacement elements for AEG ovens are available at RecambiosAEG.com or eBay.es for €30-€60. Common part numbers include 9029791480 (top element) and 9029791490 (bottom element).

4. Inspect the Oven Thermostat

The thermostat regulates the temperature. If it fails, the oven may not heat or may overheat. Symptoms include the oven never reaching the set temperature or heating erratically.

Testing the Thermostat

Locate the thermostat sensor bulb (usually in the top or back of the oven cavity). It is connected to a capillary tube that goes to the thermostat control. To test:

  • Remove the thermostat knob and unscrew the control panel to access the thermostat body.
  • Disconnect the wires and measure resistance across the thermostat terminals at room temperature. It should read near zero (continuity). If infinite, the thermostat is open and needs replacement.
  • You can also test the sensor bulb by placing it in hot water (using a thermometer) and checking if the circuit opens at the correct temperature. This requires precise measurement; if unsure, replace the thermostat.

AEG thermostat replacements like 9029791450 cost around €20-€40 from MisterRepuesto.es.

5. Check the Selector Switch and Control Board

If the heating elements and thermostat are fine, the issue may be with the function selector switch or the electronic control board. The selector switch directs power to the correct element based on the chosen function. A faulty switch can prevent heating.

Testing the Selector Switch

Remove the knob and unscrew the switch from the panel. Using a multimeter, test continuity between the common terminal and each function terminal as you rotate the switch. There should be continuity only in the positions that activate that function. If no continuity in any position, replace the switch (€15-€30).

Control Board (PCB)

The main control board is the brain of the oven. If it fails, no heat will occur. Signs of a bad board include burnt components, bulging capacitors, or error codes on the display. For example, error code E31 on some AEG models indicates a temperature sensor fault, which may be on the board. Diagnosing a PCB requires advanced electronics knowledge; if you suspect the board, it’s often more cost-effective to call a professional. However, you can visually inspect for burn marks. Replacement boards for AEG ovens cost €80-€150 and are available from Repuesto.es.

6. Examine the Oven Sensor (NTC Thermistor)

Many modern AEG ovens use a thermistor (NTC sensor) to monitor temperature and send data to the control board. If the sensor fails, the board may not activate the heating elements.

Testing the Sensor

Locate the sensor inside the oven cavity (usually a small metal probe). Disconnect it and measure resistance at room temperature. A typical NTC thermistor reads around 1 kΩ to 2 kΩ at 25°C. Check your model’s specifications. If the reading is far off or infinite, replace the sensor (€10-€20).

7. Additional Tips and When to Call a Professional

  • Fuse on the control board: Some AEG ovens have a glass fuse on the PCB. Check if it’s blown and replace with the same rating (e.g., 10A, 250V).
  • Wiring and connections: Loose or burnt connectors can interrupt power. Inspect all wire connections, especially at the heating elements and thermostat.
  • Error codes: If your oven has a digital display, note any error codes. For example, E11 may indicate a short circuit in the top sensor, while E12 points to the bottom sensor. See AEG Oven Error Codes for a full list.

If you have performed all the above checks and the oven still does not heat, the problem may be a complex control board fault or a hidden wiring issue. In such cases, contact an AEG-authorized service technician. Attempting complex repairs without proper training can be dangerous and may void warranty.
