Common Reasons Why Ovens Fail

23 March 2020

Ovens, like all appliances, are composed of multiple parts working together to improve the daily lives of those who wish to have them. As such, these parts also encounter problems that would result in the oven’s failure to operate. Below are the common reasons why ovens fail.

Broken Thermostat

A faulty or poorly secured knob can result in an inaccurate temperature setting in the oven. If the bulb is loose or damaged, the thermostat can overheat the oven. If the oven temperature is higher than the setting, then the thermostat may require replacement. The oven can also overheat if there is a malfunction with its heating element, though damage may not be easily visible. Electric ovens have a temperature sensor, but a sensor issue can cause the oven to overheat.

Grime and Dirt Buildup

Occasionally your thermostat can malfunction because it is covered with grime. The selector switch acts as a communication device between the thermostat and the heating elements. If shorted out, it may read a lower temperature, causing the heating elements to overheat. A vent blockage can also cause your oven to overheat. A power outage can make your oven’s control panel and electrical components malfunction.

Loose Wire Connections

There are a few causes for the oven having no power. As mentioned earlier, the high current drawn by the oven may cause the wire connections to melt and become loose. As such, there will not be any power supplied to the oven.

The thermal fuse might also be a cause of the oven having no power. When the thermal fuse is ‘activated’, it breaks the power supplied to the main control panel of the oven and as a result, no power is supplied to the oven.

Earth Leakage or Short Circuits

Oven tripping is the most common problem for almost all ovens. When the oven trips, there are only two likely causes – an earth leakage or a component has short-circuited in the oven. Earth leakage is very common due to the humid weather in certain locations. Lack of usage will result in too much moisture being built up in the heating elements which results in an earth leakage, thus tripping the house circuit breaker. This may be prevented by turning on the oven at least once a week for the oven to heat up.

A component short circuit in the oven may be caused by failure of the component or the presence of pests such as lizards. When there is a direct short circuit in an oven, the Main Circuit Breaker (MCB) will trip and depending on the magnitude of the short circuit, it might trip the circuit breaker for the entire building.
