To fix the E68 error code on a Frigidaire Affinity dryer, you can try the following steps:
Unplug the dryer from the power source and wait a few minutes to allow it to reset.
Check the wiring connections between the control board and the main control unit. Ensure they are secure and not damaged.
Examine the control board for any visible signs of damage or burning. If the control board appears faulty, it may need to be replaced.
If the control board is in good condition, you can try resetting the error code by entering diagnostic mode. Refer to the dryer's user manual or Frigidaire's official documentation for specific instructions on entering diagnostic mode.
If the error code persists after attempting these steps, scheduling a service appointment with a qualified technician is recommended for further assistance or exploring possible repair options.
