Gas ovens have been around for approximately two centuries. We can find them not only in our homes but in restaurants as well. All well-known brands manufacture different types and models of gas appliances for residential and light commercial use. The most famous makers in Canada are LG, Bosch, Kenmore, GE, Samsung, KitchenAid, Whirlpool, Frigidaire,  and others.

Gas Oven repair
If you enjoy cooking and having dinner with your family at home, your gas oven is the kitchen’s heart. And when it doesn’t work, it makes you feel frustrated. One of the most common problems is that your gas oven doesn’t heat up or the food isn’t heating up enough.

Having trouble with your gas oven not heating up properly? Here are five common reasons why it might be happening, along with tips on what you can do to troubleshoot and fix the issue.

  1. The igniter is faulty: Check and replace if needed.
  2. The spark electrode is damaged: Inspect and replace if necessary.
  3. The thermostat doesn’t work: Test and replace if it’s malfunctioning.
  4. The temperature is not calibrated correctly: Calibrate the settings as needed.
  5. The control or relay board is malfunctioning: Troubleshoot or replace if necessary.

You can find more detailed information below. If you fail to define and solve the problem, the licensed technicians at Fix Appliances CA are at your service to do their best to get your gas oven working.

Common reasons why your gas oven doesn’t heat up

When you start baking or broiling, set the oven temperature at 350° F for pre-heating. Then, you place your dish in the oven and wait. A little bit later, you turn the light on to check how the process goes. And when opening the oven door, you realize that the temperature is not rising. What happened? Why won’t my gas oven heat up? Before we discuss the possible problems, let’s catch on how a gas oven works.

When you choose the function to bake or to broil in your gas oven, the control sends current to the igniter or spark electrode. After that, the igniter or spark ignites the gas into a flame to heat up the oven. The igniter will keep the safety valve open until the oven reaches the assigned temperature. A thermostat bulb monitors until the selected temperature is reached. Then the control shuts off the voltage to the igniter, and the gas supply to the burner will be shut off as well. This repeated cycle in the baking or broiling is to maintain the proper temperature during the process.

It should be considered that the selected temperature is the average because it fluctuates throughout the baking or broiling process. The convection ovens reduce this fluctuation due to the fan with or without a heating element that circulates the heated air over the oven.

Thus, the possible reasons for why your gas oven doesn’t heat up can be the following:

Reason #1 – The igniter is faulty

Sooner or later, an igniter stops working correctly. All the time, after turning the oven on, you should keep an eye on whether the igniter begins to glow or not. If the burner doesn’t light, the igniter is far more likely to be faulty.

Reason #2 – The spark electrode is damaged

Some gas ovens use a spark electrode to ignite the gas. Any damage to this component could determine that it will fail.

Reason #3 – The thermostat doesn’t work

The thermostat monitors the temperature in the oven and defines when the current should be shut off. Thus, it’s necessary to determine whether this part has electrical continuity. It can be defective.

Reason #4 – The temperature is not calibrated correctly

Sometimes it’s possible that your gas oven is heating, but you can see the wrong temperature on the display. It means that the gas oven is calibrated incorrectly.

The wire connection is burnt or not tight enough. As a rule, an igniter or electrode power supply wire could burn near the heat source. Such damages are mostly visible. In this case, you must ensure the wire is not damaged and secured.

Reason #5 – The control or relay board is malfunctioning

If you are convinced and exclude the failure of other parts, the possible cause can be in the control or relay board.

Troubleshooting When Your Gas Oven Is Not Heating Up

Your gas oven is one of the most important appliances though you can use it not very often. But if you’ve decided to bake a cake, cookies, or broil something, you need it. When it doesn’t work, it’s frustrating. Here you can find the solutions to fixing the common causes that won’t take so long.

But first of all, you should know Ontario regulation for your safety certificate is required for various activities. No person shall install, alter, purge, activate, repair, service or remove any appliance or any equipment unless the person is the holder of a certificate for that purpose under Ontario Regulation 215/01

Igniter — As time goes on, the igniter weakens. The temperature is much less, and the oven won’t heat past 350°. You can test the igniter using a multimeter for continuity. You should check a continuous electrical path in it. If you find out it is damaged, it must be replaced.

The oven is slow to heat up — Here are several reasons to try troubleshooting. As noted earlier, you can face a problem with the thermostat or temperature sensor. You can check it using a multimeter and ohmmeter to ensure it works.

If everything is functional, you should recalibrate the oven. Preheat the oven to 350 degrees Fahrenheit. Check the temperature inside with the help of a thermometer every 20 minutes from 90 to 180 minutes. Then you should sum up all readings and divide them by the number of them to calculate the average temperature of your oven. After that, you can adjust the temperature dial of the oven accordingly.

If you made simple steps to verify the issues with the parts of your oven and realized that it’s still not working, the problem can be with the control board or relay board. As you can’t test it easily, you should inspect it for signs of burning or short-circuit elements (for example, self-cleaning oven fire).

But the problem with the gas oven is not fun, and sometimes it’s difficult to treat on your own. In this case, trust pros from Fix Appliances CA to handle troubleshooting.
