When the oven stops heating, the first thought is often: “is the device out?”
In fact, it is usually one of the three classic faults -. broken heater, faulty temperature sensor or fault in the control module. Finding the right error saves both time and money.
1. The heater - the most common culprit
The heating elements of the oven (top, bottom and circular heater around the fan) operate in a continuous hot environment. Over time, the metal will fatigue and the heater may break - visibly or internally.
Signs that the heater is out:
-
The oven does not heat up at all, or only heats up some parts.
-
Baking remains uneven.
-
The heater may be blackened or cracked.
Solution:
The heater is measured with a multimeter. If the value is incorrect or the heater is short-circuited, it must be replaced.
The work is not dangerous for the do-it-yourselfer, but it requires dismantling the equipment and having the right spare parts - something the 1meister does every day.
2. Thermostat or temperature sensor - the oven is heating up incorrectly.
If the oven heats up, but not correctly (e.g. 200 °C, but it's really only 100 °C), this indicates a sensor or thermostat fault.
The thermostat sends the wrong signal to the heating elements to start or stop.
Features:
-
The oven heats up very slowly or not enough.
-
When baking, you need to raise the temperature a lot.
-
Sometimes the oven turns itself off too early.
Solution:
A thermostat or NTC sensor is a consumable part that can be replaced.
A professional measurement will give you the answer in minutes - 1meister's technician will do it on the spot.
3. Control module or „brain“
If all the heating elements and sensors are in good working order, but the oven still doesn't work, the likely cause is. electronic board failure.
On older ovens, triacs or relays may burn out; on newer models, a program will give a warning that the oven will not start or will switch itself off immediately after switching on.
Features:
-
The oven screen is working, but the heating is not activated.
-
The clock is ticking, the programmes are changing, but there is no heat.
-
Occasionally heats up and then stops working - intermittent fault.
Solution:
Repairing the control module is possible - we repair or replace faulty components, not replace the whole board if it's not needed.
This saves costs for the customer and prolongs the life of the equipment.
4. Other possible reasons
-
Bitter selection system or push-button mechanism - especially on mechanical cookers.
-
Switching relay or protection, which has burnt due to loss of contact.
-
Power cable or plug, which has been damaged by heat.
All of these are repairable but require specialist intervention to ensure electrical safety.
5. When to call a champion?
If the oven does not heat up at all or heats unstably, it's a good idea to have it checked before it causes a major problem.
Checking electric heaters requires measuring equipment and experience - home trials can end in a short circuit.
1master helps to diagnose and quickly repair stove and oven faults using spare parts that meet the manufacturer's requirements.
