Frigidaire Affinity Dryer (model LEQ7000ES0) error code E68... Continues to pop-up and shut dryer off. Can you assist in resolving this issue?

E68 is a stuck button error code... There is a diagnostic video for this on YouTube. You will have to get a new control board to fix the problem because the buttons are part of the board... Frigidaire Dryer Main Control Board 134557200

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle.

Good Afternoon David,

I understand that your Frigidaire Affinity dryer, model# LEQ6000ES2, is showing you an error code of E68 and will not start. I also see that you have changed the thermal limiter. Looking at what the E68 error code means, a key or button stuck, there could be something else causing the code to come up. I suggest contacting your local authorized technician for further assistance. They will be able to diagnose your appliance, determine what is causing the E68, and repair your dryer. Hope this is helpful.

-Best Regards-

You may have an igniter issue, thermostat, or a gas valve coil issue. Make sure a heat selection is made also.

Frigidaire Affinity dryer model AEQ7000ESO error code E68 (stuck button). Sometimes a 'stuck button' code really is a stuck button. I took the circuit board off the front panel.On the back side of the front panel, each button has 3 short plastic posts, 2 on one side and 1 on the other.The center part moves to push a longer piece that contacts the circuit board. When I push the top of a front stadium-shaped button, the center plastic piece moves too far, touches the short post, and sticks (maybe due to age). When I push the bottom of the front button, the plastic piece goes far enough to contact the circuit board and not far enough to touch the short post. To prevent a stuck button, we now press the bottom of the front buttons.So far so good. If it happens again, I plan to shave or file a little bit off the top edge of the post to give it more clearance. 1st photo: pencil points to stuck parts. 2nd photo: unstuck parts, 3rd photo: the front of our dryer.

The error code E68 means a key or button is stuck. Check the buttons by pressing them one at a time to find the stuck one or enter the service diagnostic mode then the key function test. Click on the link below for the detailed instructions.
