If your Frigidaire oven is not heating up, it could be due to a range of issues, including electrical problems, defective heating elements, low gas pressure, damaged sensors, control board issues, and malfunctioning fans, doors, or vents. It’s crucial to diagnose the problem accurately before taking any action to ensure you address the root cause effectively.
According to Atlantic Coast Appliance, the most common oven problem is the oven not heating up. It is so common that when you look up oven problems on Google, you will instantly notice how almost every article includes the issue of ovens working but not heating up.
Most articles state that the most typical reason why your oven is having heating problems is due to a faulty or dirty igniter, which must be cleaned or replaced immediately. It is a common issue among people who use the oven, but you must remember that every brand has distinct ways and procedures for solving the issues you are facing.
If you own a Frigidaire oven, this article will help you. You will find some of the most common reasons you are experiencing this problem here. This article will explain these specific reasons and how you can solve and fix them in no time.
Reasons why your Frigidaire oven is not Heating up
Here are six common reasons why your oven is not heating up:
- Electrical issues
- Defective heating elements
- Low gas pressure
- Damaged sensor
- Control board issues
- A malfunctioning fan, door, or vent
Let’s look through these reasons closely.
Electrical Problems
Since Frigidaire gas ovens are mainly powered by gas, they are not particularly prone to electrical problems. Furthermore, a power outage or wiring issues will influence the control panel, so you’ll know there’s an electrical problem as soon as you interact with the settings.
A Frigidaire electric oven, on the other hand, will not heat up if there is a problem with the voltage, current, or wiring. You’re undoubtedly aware that a 240V power outlet and a 30A to 60A double-pole circuit breaker are required for your Frigidaire electric oven. A 20A circuit is the bare minimum.
As a result, a severe voltage or amperage fluctuation might cause an electric Frigidaire oven to fail to heat up. I’m assuming your circuit breaker is not tripped and that the wall outlet is operational. Otherwise, you won’t be able to identify the issue.
Frayed or loose wire can also cause heating issues, particularly at terminal connections. A bad connection or faulty wiring may not disable the control board or display panel, allowing you to utilize the knobs, buttons, or touchpad. Nevertheless, the heating element is inoperable.
Additionally, the terminal block itself might be faulty. So, even though the wires are in good condition, there is no voltage or current fluctuation, and everything else is in order, your Frigidaire electric oven will still not heat up due to a faulty terminal block.
How to Fix Oven Not Heating Up Due To Electrical Problems
The following are the processes that will help you examine and repair the electrical faults, including those in the terminal block:
- Check the circuit breaker and ensure it is on, or reset it.
- Test the wall outlet for power or use another 240V source.
- Don’t use extension cords or any such accessories.
- Unplug the oven before accessing its internal components.
- Take off the rear access panel to inspect the terminals.
- Ensure the terminal wires are working and snugly fitted.
- Replace the wires if they are burnt, frayed, or damaged or
- You may have to replace the oven’s terminal block.
Don’t suspect the terminal block unless both your electric oven and stove aren’t heating. Electric ovens, such as those from Frigidaire, have three cables linked to the terminal block. The left and right wires are linked to 120V terminals in the wall socket, for a total of 240V.
As a result, if you use a voltmeter to measure the voltage on the left and center wires of the oven terminals, you will get a reading of ~120V. Similarly, if you test the center and right wires on the oven terminals, you’ll obtain a ~120V result. A 240V reading will be obtained by testing the left and right terminals.
If you didn’t get these readings, then the cables are surely defective, or there’s a voltage problem with the wall outlet. If you want to perform this test, use extra caution since you will need to connect the oven to measure the voltage. If you don’t have enough experience, I don’t advocate attempting this step.

Low Gas Pressure
If you own a Frigidaire electric oven, then low gas pressure is not a problem for you. Additionally, a gas oven’s low pressure might not be the oven’s fault. The oven can’t be fixed until the gas pressure is increased. Moreover, the stove burners will not work properly if the gas pressure is low.
However, like any other oven, every Frigidaire gas oven features a safety valve. You may have low gas pressure in the oven if this safety valve is broken or stuck. If the safety valve malfunctions and stays open, it could cause a gas leak in your home.
How To Resolve Oven Low Pressure Issues
The following are the steps on how you can check and make the necessary adjustments that can be made to restore normal gas pressure:
- Ensure the main gas supply valve is on.
- Check if the oven burners have flames.
- Observe the flames around the burners.
- If the flames are weak, check the gas pressure. The natural gas supply pressure is ~17 millibars (0.25 psi).
A malfunctioning oven safety valve could be the cause of low gas pressure. In addition, if the safety valve in your Frigidaire gas oven won’t open, it could be due to a faulty igniter.
The burners will not light if the igniter is broken. In addition, the burners might turn off during preheating if the igniter is malfunctioning and closing the safety valve. Therefore, if the gas oven does not produce flames, either the igniter or the safety valve needs to be immediately replaced.
Defective Sensor
A defective sensor or resistance temperature detector (RTD) in your Frigidaire oven can prevent it from heating up, whether the oven is gas or electric. This sensor is usually at the back if you look inside the cavity.
A misaligned, failing, or broken sensor can affect preheating and the ultimate temperature. If the temperature detector touches the cavity or wall, it may sense a higher temperature than what is really inside the oven and shut it. So, you have to fix or replace the defective sensor.
How Can You Fix a Defective Sensor Problem
A resistance temperature detector that has become unaligned can still be corrected. The sensor must be kept away from the cavity in order to achieve this. You should inspect the wiring or harness to make sure it is connected properly. If the sensor is not working properly, you’ll need to check its functionality and, if necessary, replace the probe.
Here’s how to check a Frigidaire oven’s temperature sensor:
- Unplug the appliance and remove the rear access panel.
- Take apart the wire harness connected to the sensor.
- Get a multimeter and touch the probes at the terminal
- Check if the reading is ~1090 ohms at room temperature. If the resistance is too far off, the temperature sensor is bad.
- Replace the RTD or resistance temperature detector.
Control Board Issues
Multiple control boards are commonly installed in Frigidaire appliances. There could be an electronic surface element control board (ESE) and an electronic oven control (EOC) in your stove. Additionally, your model might have a small oven control board.
It is also possible that the clock timer control board is defective. Setting the clock usually resolves problems with a timer. However, if the main EOC’s relays are broken or the mini oven’s control board is faulty, you will need to replace both of these parts. Your oven has individual racks for baking and broiling. The control board also features a power relay.
How to Fix it
If the display, knobs, buttons, touchpad, etc. on a Frigidaire oven respond to your input, the control board may be somewhat functional. So, test to see if the oven’s bake or broil switch is broken. If either isn’t working, the corresponding relay on the board can be replaced. The power relay should be changed if neither is functioning.
You can check out this video on how you can replace your Frigidaire oven’s control board at home.
If the bake, broil, and power relays don’t fix the issue, the control board will need to be replaced.
Problems with the Vents, Doors, or Fans
If you are having problems with your oven not having enough heat for you to cook and all of the aforementioned reasons have checked out, then you must consider checking your oven vents, doors, and fans. A Frigidaire oven won’t heat up if the fan isn’t working, the door is leaking, or the vent is clogged.
If the vent of your oven is blocked or the fan does not work, then the temperature sensor will automatically turn it off, preventing your oven from heating up. A door with a leaky gasket or seal will allow hot air to escape, preventing your Frigidaire oven from heating to your desired temperature or cooking setting.
How to Fix it
The following are the most frequently used solutions to these problems:
- If your oven’s convection fan is already broken, you must replace it immediately. However, before planning to replace your oven’s fan, you must first check if it is really the problem.
First, you should try turning the blades by hand. If the fan’s blades spin freely, then the problem is likely on your oven’s control board. But if they won’t spin freely, it’s probably because the bearings inside the fan motor are damaged and must be replaced immediately. To replace your oven’s convection fan, you can check this video out by Repair Clinic:
- Replace the door gasket if it is worn out or damaged. Before trying to remove your oven door, you must check all the aforementioned reasons above and confirm that this is the reason why your oven won’t heat up.
If you are sure enough, the first thing you have to do is to make sure that your oven is unplugged to avoid any accidents as you try to fix your oven. Remember, you want your oven to heat up, you’re not trying to electrocute yourself.
Next, clean the surrounding areas of your oven door. It will allow you to locate small screws easily. Then, you can now open the door to its full horizontal position to access every hinge properly using a flathead screwdriver. You must remember not to lean heavily on the sides and the middle glass for it might shatter your oven door which can harm you.
To remove the oven door, grab the top of the oven door on both sides of the handle. To detach the oven door from the hinge supports at the base of the fixture, lift it up and in a slight arc toward you. To unlock the door from its hinge levers, rotate the top toward the shooting range as you pull toward you.
A Frigidaire oven door can be ordered from your manufacturer. You can watch the video from Repair Clinic on how you can replace your oven door.
However, if you are not confident enough on how to do the next step and replace your oven door with a new one, it is better to let an experienced repairman do it to avoid any complications in the future.
- It is important to keep your oven vent clean and clear of all dust, crumbs, or any residue from past cooking. Your oven vent must be regularly cleaned and maintained. You can clean your oven vents behind your oven door using a tissue and a butter knife. Since oven vents are really small and spacious, wrap your tissue in a butter knife and use it to wipe your built-in oven vents.
If you are not confident with doing any of these replacement methods given above, you can always call your oven’s manufacturer or any experienced technicians who know what to do.
Conclusion
Different issues might cause a Frigidaire oven to stop heating. It may be because of some electrical issues, faulty heating elements, low gas pressure, defective sensors, problems with your control boards, and faulty fans, doors, and vents. Any of this can be why your oven does not reach your desired temperature, which prevents you from using your oven efficiently.
If you have tried the steps mentioned above to fix the possible reasons why your oven is not heating up, and none of them work, then your problem might be because of some defects inside your oven. If this is the case, it is best to contact your oven’s manufacturer or a qualified and experienced appliance expert to fix your oven issues and have them checked properly.
