If your oven is not maintaining the correct temperature, it could be due to a malfunctioning thermostat, a faulty heating element, or a malfunctioning temperature sensor. The issue may also simply be a need for calibration or keeping the door closed.
It could be a simple connection issue. Voltage fluctuation can cause inconsistent temperature regulation. You should check the power source, the socket, the plug, the cord and the fuse, or circuit breaker.
A broken electric oven thermostat is most likely the cause of your electric oven's temperature fluctuation. Your oven thermostat is the oven part which regulates the temperature. If the thermostat is broken, it will no longer be able to keep the temperature at a stable level and will cause fluctuation.
Remove the oven temperature knob and turn it over. It should have one or two screws on the back. If the oven is running cold, you will want to turn the screws counterclockwise, and if it is running hot, you will want to turn them clockwise. Turn them gradually, about an eighth of a turn each time.
Place the multimeter on the thermostat. If the thermostat has a reading of zero or as close to zero as possible, it is working fine. However, if it has no reading at all, your oven thermostat is faulty and will need replacing.
Your thermostat is responsible for controlling the temperature of your oven. If you find that your food is over or undercooked after setting the temperature correctly there's a chance that your thermostat is faulty. That's right, maybe it isn't your cooking skills, it's the thermostat.
We recommend replacing the oven thermostat if it temperature changes between uses or is off by more than 10% of the set temperature.
When your oven is heating but not reaching the set temperature, there may be an issue with the temperature settings, temperature sensor or calibration. The solution to your oven's heating problems could be checking to make sure your oven is set to the proper unit of measurement.
Once you've noted down the thermometer's readings, check them against the temperature you've set the oven to. If it's more than 15°F (10°C) off, you'll want to recalibrate it. If temperature is off by a lot, you should call a technician and not try to calibrate it yourself.
Issues with the oven temperature sensor, thermostat, heating elements, gas igniter, electronic control board, or door hinges can all contribute to temperature inconsistencies, and identifying and replacing faulty components is key to restoring proper oven function.
To test the oven: Hang an oven thermometer in the center of the middle rack and preheat the oven to 350˚F (176.67˚C). Allow the oven to preheat for at least 20 minutes and take a temperature reading. This will tell you if the oven is even reaching the desired temperature from the beginning.
The lifespan of a thermostat is dependent on several factors, including the type of thermostat, usage, and maintenance. On average, most thermostats last about 10 years, depending on the model, usage, and proper maintenance.
This fluctuation is common for our Ovens. Some may fluctuate a little more, some a little less. The temperature swing can vary by how and where you are measuring the temperature in the Oven. The temperature swing can also be influenced by the room temperature or number of door openings.
If you notice that your electric oven isn't heating up to the correct temperature and food comes out under-cooked, this many be caused by a defective electric oven thermostat. Thermostats measure the temperature inside the oven cavity, switching the electric element on and off to maintain the desired temperature.
5 Steps to Calibrate Electric Ovens With Analog Controls
Pull the temperature knob off your oven thermostat. Locate the screw(s) on the back. Turn the screw(s) clockwise to decrease the temperature. Turn the screw(s) counterclockwise to increase the temperature.
Why Won't My Oven Hold Temperature? If your oven is not maintaining the correct temperature, it could be due to a malfunctioning thermostat, a faulty heating element, or a malfunctioning temperature sensor. The issue may also simply be a need for calibration or keeping the door closed.
The most apparent signs the heating element is broken are visible damages. Take time to check your oven and remove the heating element to inspect it thoroughly. While you're at it, be on the lookout for burns, blistering, or cracks. If you notice one or some of these signs, it's time to have it replaced.
A room temperature oven thermostat should have an ohm reading of 1,000 - 1,100. A reading much higher or lower than this is an indication that your oven thermostat is broken or damaged. If this is the case, you should replace your thermostat.
To replace your oven sensor, you'll pay between $100 and $250.
The life expectancy of an electric oven is around 13 - 15 years. The life expectancy of a gas oven is around 15 years. The life expectancy of a dual-fuel oven is also around 15 years. However, the lifespan of these kitchen appliances depends on how frequently you use them.
