Control board problem. Unplug the dryer for 5 minutes to reset the control board. Plug the dryer in and start a cycle. If the code appears, replace the electronic control board.

Hello friend, thank you for your post!

Based off the information you have provided, I understand that your Frigidaire dryer is displaying an "E52" code and the dryer will not start. Typically an "E52" code stands for motor fault, I would attempt to perform a reset on your appliance by disconnecting power for roughly ten minutes. After the reset if you are still receiving the error code I would recommend having a professional come out to diagnose and repair the appliance. Best of luck. -Matt

Hi Friend, this is Z. I am happy to assist you!

I see that you have a Frigidaire Affinity dryer and I'm presuming you are seeking information on how to clear error codes on your dryer. May I please have your model number? The serial tag, which lists your model number, is typically located on the upper front, as you open the door. With this information I can help pinpoint the exact problem. In the meantime, you can reset your dryer by either unplugging your dryer or flipping off the breaker for roughly ten minutes. This often clears most false error codes. Hope this helps!

Heater has an open circuit and need to be replaced. Here is the part you need.

AD is not actually an error code, but is typically considered an Air Dry setting or feature on the unit.

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.
