In this video I show you how to troubleshoot your Frigidaire Dryer that has an error code E68.

This code refers to a Stuck Button on your dryer. To find out which button is stuck you would want to run the function test mode of your dryer and run the key test.

The diagnostic test will show you what button is not functioning properly. You should remove the control panel and inspect each button for proper function.

Reassemble the dryer and re run the test again. If the button works now great. If not you will have to replace the dryer’s main control to fix the problem.

Here is a video showing you how to disassemble this dryer and replace the belt
