I have a fridgidaire Model FEF366EBD, the stove elements work and the broiler element works but the lower oven element doesn't.

sounds like you got a defective element

Manufacture and model would be nice ohm out the bake element might be open some are in the oven cavity others are hidden below the lower oven plate and have to check from the rear by removing back cover in the bake mode the broil element element cycles on/off thats why you have some heat.

Reseating the Element The broiler is heated using an electric element which should be clipped in to the top of the broiler enclosure. If this has come loose then it might not be making contact with the necessary terminals. Try to reseat the terminal but before doing so you must ensure that the electricity is turned off.
Testing the Element The element is what heats up and cooks the food in the broiler. Over time the heat can damage the broiler element. These elements are supported by stand-offs and if the element burns out or becomes damaged then this can be a common reason why the broiler isn't working.
The easiest way to test whether this is working is to turn the broiler on and look at the element. If it is working correctly then the element should be glowing red.
Another slightly more complicated test for the broiler element is to remove the element from the oven and disconnect it. Then use a multimeter to check the continuity of the element. Set the multi-meter to measure resistance and then put it either side of the element. The normal measurement should be between 20 and 40 ohms. If the element is infinitely resistant then this means it's broken and will need to be replaced.
Testing Oven Controls Another reason why the broiler will fail to work is because of problems with the oven controls. A thermostat is used to set the temperature of the broiler, and the oven selector controls are used to control the setting of the broiler.
Turn the oven controls on to see whether the broiler is working properly. If not the controls can be removed and tested using a multimeter. Check the outputs to ensure that the controls are working correctly.
These can also be replaced if required by fitting a replacement part designed specifically for your oven.

Hi.

If the element does not turn off, possible faults are:

Shorted temperature probe.
Test temperature probe reading impedance. If impedance is zero or lower than 0.500 Ohms, the the probe is shorted. A good probe reads about 1KOhms.

Contact at element. A contact in element wiring harness may cause the element to stay on. Do continuity test between ground and element and on wiring harness.

Defective control module.
If problem is none of the above, then it is the oven electronic control(ERC). The ERC can be tested reading voltages.

Testing must be done by a trained technician.

Hi,

If your electric oven is taking too long to heat or just not heating up right, then check out this tip that will give more detail about your problem.

Hi,
The baking element is probably the problem...

naps is asking oven element is not working or starting dosen't light up

I would say to go and reset your curciut breaker first if this is a electric oven. needs 220 volts for both element to work

Visually inspect the element for any kind of rupture on the shield covering the element. If it looks good the next step is the wire connections at the back of the element. Most likely is has a burnt wire.You will have to pull the back cover off to check this.
