A damaged ignited is a very common issue in gas ovens.

If your gas oven is not heating properly, your oven igniter might be faulty. To check if this is the case, you can simply attempt to light one of the burners on top of the oven.

Once you try to put on your gas oven, it will usually make a clicking sound. If it doesn’t come on after a few minutes, you might want to consider replacing your oven igniter

To do this

  1. You will have to switch off all the oven controls and unplug the oven from the gas pipe
  2. Take out the oven rack
  3. Unscrew the compartment containing the igniter
  4. Check if the coil or any part of the igniter is a different color from the rest,
  5. Once you have established that the igniter is faulty
  6. Replace the igniter
  7. Screw back the compartment and tighten the screw properly
  8. Your igniter should be ready to use

Of course, none of this should be attempted if you are not adept with appliance repair.

2. Gas Leakage

This is not the most common cause of heating problems in gas ovens, but it is a possibility.

If you have checked out other issues and you seem not to know why your gas oven is not heating up properly, it might be due to a gas leakage.

The gas can also be interrupted by a damaged or a clogged gas regulator. This is especially true if you are using gas cylinder as the source.

To check if leaking gas is the problem, for starters you’ll be able to smell the distinct smell of the gas if it severe.

However, some gas leaks can be very minute that can cause regulator in the temperature control. To check this.

  1. Check if the gas valve is on
  2. Check all the other valves remotely connected to your oven
  3. Check the pipes
  4. Check the gas regulator if using a cylinder

If there are any discrepancies, you should immediately seize any more cooking on it until the issue is addresses.

Why is My Electric Oven Not Heating Up Properly

Most times, when your electric oven is faulty, you can spot it almost immediately, it might come on but refuse to heat up or it might choose not to come on at all.

There are so many possible reasons for this and to check the exact cause of the ovens lack of heat, you will need a multimeter and the oven manual.

Below, we will consider some options and some possible fixes for the problem

Note

Before attempting any repairs, it is of utmost importance that you disconnect your oven from the electrical source. Make sure nothing is placed inside or on top to avoid accidents.

1. The Heating Element is Spoiled

Heating Element

If the heating elements are not turning bright red at full heat, they are probably not heating to the desired level.

This is the major problem people check for when an electric oven is not heating up properly. This issue applies to both range or toaster ovens.

To determine if this is the issue, turn on the oven. Once it begins to heat, the heating element turns a bright red. If your heating element is refusing to heat up properly, it might not turn as bright as it normally would.

In this situation you might need to change the heating element,

Unscrew the heating element, replace and screw back in place

2. If the Fuse is Blown

Occasionally, oven fuses get blown, it could be due to a lot of heat in the oven. When this occurs, you will need to replace it with a new fuse.

To do this you will need to check if the problem is caused by an oven fuse with a multimeter, this will be used to check for continuity in the fuse function. If the multimeter reads negative, you might have to replace it.

Other Reasons Why Your Oven is Not Heating Up Properly

These apply to both your electric and gas oven.

1. Thermostat Sensor Control is Malfunctioning

The thermostat sensor is a sensor that the oven usually uses to regulate the oven temperature. It is part of an internal control that regulates the oven heat.

When the thermostat control goes out, the temperature of the oven is not regulated and therefore you might not get the most accurate temperature.

To check this, you can place in a oven thermometer to check whether it is achieving the desired temperature accurately. If the thermometer does not display the correct temperature, then its thermostat can be damaged.

Calibration

Once you have check all the other issues and you believe that thermostat is simply not calibrated properly, then you can do manual calibration.

To check if this is the issue, simply get an oven thermometer and turn on the oven to 400 °F, use the oven thermometer to test the oven temperature every 15 minutes for 2 hours.

Divide the addition of your reading by the number of times you have taken the readings. This will give you the average temperature achieved during the 2 hours time.

Then adjust your oven based on your findings. The oven can be plus or minus from the desired 400 °F.

2. The Knob Selector is Broken

If your oven knob selector is faulty, there will be nothing to control the oven with.

Perhaps your knob selector is simply not positioning itself at the right temperature setting.

Knowing if this is a problem for your oven is pretty straightforward. Once you have this problem, you will need to replace the knob selector, but if you have an urgent need, simply take out the defective knob with a plier and turn the oven shaft directly.

This should work in the meantime

To replace the knob selector, simply get a new knob and put it over the exposed shaft, your knob selector will be as good as new.
