My oven does not work, how to repair an oven

My oven is not working, what do I do?

.

The ovenis, increasingly, a great ally in the preparation of food in our kitchen. There are more and more fans to prepare pastries at home: they are healthier recipes and we control the quality of the ingredients. We also find that many food recipes use the oven at some stage. It is also a great help for those who, instead of enjoying time in the kitchen, opt for precooked dishes: pizzas, lasagnas, empanada... in the supermarket there is a whole area of quick solutions for baking without heating up your head.

But, the thing is, the more hours of use, the more chances our oven has to break. Electrotodo.es offers you a small repair tutorial so that you can locate the most common faults and repair the oven with your own hands.

What type of oven do you have

.


The first thing to keep in mind is what type of oven we have at home:

  • The classic models essentially had a mechanical timer and thermostat, a safety thermostat and 2 or three heating elements (they also have one or 2 fans, but they usually do not cause serious malfunctions in the appliance). Simple models with these parts are still on the market today, and are usually the easiest to repair (and the easiest to understand).
  • The modern electronic models basically have an electronic module that regulates the thermostats (NTC sensors) or a sensor and a mechanical thermostat. This module also regulates the timer and other additional functions of some ovens. In these models there are failures that depend on the plate that can only be located by discarding the rest of the parts of the oven, so their repair can be more complicated.

When in a classic model the light turns on but the oven does not heat:

Resistance how to repair oven

  • Check the resistors. When any of the resistors is shorted at any point, energy is reaching it but it cannot transform it into heat. Some resistors work by connecting them directly to 220V, but they can also be checked with a multimeter or electrical tester: in position 200 K? if when placing the tips at each end of the resistor marks "1" (as in figure 1), the resistor is cut. We have located the fault, if there is no other problem, just replace the part to repair the oven.

Multimeter for oven repair

Oven Safety Thermostat

Safety thermostat

  • Check the safety thermostat. There is a thermostat on the top rear of the appliance, whose mission is to cut off the power supply when there is overheating. It can be measured with a multimeter in the same way as the resistance. In some cases they break down due to use, without overheating, however, it is possible that they cut off the power supply due to a malfunction of the general thermostat. Therefore, if the repair requires the replacement of this part, it is advisable to also replace the adjustable thermostat of the appliance so that it does not happen again.

  • Check the thermostat of the appliance. The thermostat is the part that we regulate to set the oven temperature. A malfunction in this part of the oven can cause the appliance not to heat or the heating elements to heat non-stop, reaching excessive temperatures. The continuity of the circuit in the thermostat depends on the temperature at which the probe is, so it is more difficult to measure, although it does govern the above for checking resistors and safety thermostat.

When in a classic model the device does not turn on i.e.: nothing works:

Selector for oven repair

  • Check switch. The switch, or position selector, may burn out, leaving the appliance without electrical power. In this case, the fault is repaired by replacing the part. It is always recommended to replace all the fast on connectors that reach the switch, otherwise, the fault will be reproduced sooner than we want.

  • Check the operation of the clock/timer. This case is rare, although there are times when, if we never use the timer function, simply at some point the position has been changed to "off" and the oven does not work. There is not even a malfunction, just move the selector to check it. Another option is that the internal mechanism is damaged or the connections are burned. In the latter case, it is also advisable to replace the fast on connectors that have been burned to avoid future complications.

These are the parts that cause problems in ovens. In the cases of digital ovens, or in mixed ovens, some of these indications can be followed, depending on the model they have some or other parts. When the problem of the digital oven is that there is no power supply coming from the electronic board, it is necessary to evaluate the possibility that it is the complete module that causes the failure, although that is another story.
