You most likely just have a weak ignitor. What you describe are classic symptoms, except I have never tried turning gas off.
If you have an amp clamp, check the amp draw of the ignitor. Clamp it on with the oven off. Turn the oven on and watch the amp draw. It will start climbing as it heats up and open the valve at about 3.2 amps. If you get 3.2 amps and it still doesn't light, you probably have a valve problem. I expect you will see it get up to 2.8- 3.0 then linger there for a while. This causes slow and erratic operation of the gas valve.
Even if you find this not to be the problem, this is the very first step to diagnosing a gas oven. You have to know the amp draw of the ignitor before you can go any further.
Post back to let me know what you find.
The best way to test the igintor is with an amp meter. Connect a clamp on amp probe to one of wires going to the ignitor (either one is fine) turn the oven on, match the current you get from the amp probe to the rating on the gas valve to see if you have enough current. (typically you need 3.2 amps for most systems).
As ignitors get weak the resistance in them gets higher causing the amp draw to go down.
You can also get 'a feel' for the strength of the ignitor by how bright it glows, when working right, the orange will be bright almost whiteish in color. As it ages and weakens it will be more of a dull orange.
As a rule of thumb, if the ignitor is glowing and the burner will not come on the ignitor is bad.
Your glowbar ignitor part must be replaced, Unplug
the range and turn off the gas. Remove yje oven racks, The oven base
pan. Then remove the flame spreader. You will see the glowbar ignitor
attached to the side of the bake burner. Remove it and replace it with
a new ignitor. Replace all the range parts.Turn on the power and turn
on the gas supply.

Have you spilt anything on the burner? If so it will need to be cleaned,you will need to do the following (you need a pin, a matchstick, a drinking straw and a torch):
Make sure the oven control and the electric isolated is off please, remove the shelves, using the torch, inspect the oven burner, if there is no apparent blockage, disregard the following advice and seek the help of a 'Gas Safe' engineer in your area.
If it is blocked,using a pin or matchstick clean the holes in the burner, and use the drinking straw to blow the debris away. Move away from the burner, and see if it lights.
If this fails to work it could mean that the ignition is in the incorret position allowing for explosive ignition. See advice from a 'Gas Safe' qualified engineer.

If your Frigidaire oven's broiler unexpectedly turned on while you were baking at a low temperature, it could indicate an issue with the oven's temperature control system. Here are a few possible explanations and troubleshooting steps:
Incorrect oven setting: Double-check that you have selected the correct oven function and temperature settings. Ensure that you have chosen the "bake" function rather than the "broil" function. Also, verify that the temperature setting is appropriate for baking.
Malfunctioning temperature sensor: The oven's temperature sensor, also known as the oven thermostat, could be faulty. A malfunctioning sensor may send incorrect temperature readings to the oven control board, causing it to activate the broiler unexpectedly. Consider contacting a professional technician to inspect and potentially replace the temperature sensor if necessary.
Control board issue: The oven control board, which regulates various oven functions, could be experiencing a malfunction. If the control board is sending incorrect signals to the broiler, it may activate when it shouldn't. Consult a professional technician to assess and repair the control board if needed.
Wiring or electrical problem: Inspect the oven's wiring and electrical connections for any signs of damage or loose connections. Faulty wiring or poor electrical connections can cause erratic oven behavior. It's advisable to have a qualified technician examine the electrical components to ensure they are functioning correctly.
Based on the information provided, it seems like there may have been a problem with the oven's thermostat or temperature sensor. It's possible that these components malfunctioned, causing the oven to continue heating beyond the set temperature.
Since the issue seems to have resolved itself and the oven is currently functioning properly, it's difficult to determine the exact cause of the problem. However, if the issue occurs again, it's important to have a professional technician inspect and repair the oven to ensure that it operates safely and efficiently.
Intermittent issues can be difficult to diagnose and can potentially be dangerous, so it's important to take any signs of malfunction seriously and address them promptly.
Error Code: F3
Solution: The oven temperature sensor may be failing or defective. First, check sensor harness and harness connection between oven sensor and oven control to see if there is an issue with loose wires or visible damage to the wiring, such as a burnt wire.Sep 1, 2018
