The E64 error on your Frigidaire dryer means the main control board has lost communication with the motor control board or drive motor. This is usually an electrical connection issue rather than a broken part, so check the wiring first before replacing anything.

Error code E64
Meaning Communication failure between the main control board and the motor control board/drive motor
Severity Medium — the dryer will usually stop mid-cycle or refuse to start
Time to fix 15–40 minutes
Tools needed Multimeter, screwdriver (Phillips and flathead)

What the E64 error means

Frigidaire dryers use a network of internal wiring harnesses to let the main control board talk to other components, including the motor control board that runs the drum motor. When that communication drops out, the control board displays E64 to flag the problem. It’s often triggered by a loose connector, a pinched wire, or a harness that has worked itself free during normal vibration and use.

Common causes

  • Loose or disconnected wiring harness between the main control board and motor control board
  • Corroded or dirty connector pins preventing a clean electrical signal
  • A faulty motor control board that isn’t sending or receiving signals correctly
  • A failing main control board
  • Damaged wiring caused by heat exposure or rubbing against the drum or cabinet
  • A loose ground connection affecting signal integrity

How to fix the E64 error

  1. Power down and unplug the dryer — Always disconnect power at the outlet before opening any panels to avoid electrical shock.
  2. Locate and inspect the wiring harnesses — Remove the back or top panel (check your model’s service sheet) and find the connectors linking the main control board to the motor control board.
  3. Reseat every connector — Unplug and firmly re-plug each harness connector along that circuit, checking for bent or corroded pins as you go.
  4. Test continuity with a multimeter — Check the wiring harness for continuity end to end; replace any wire showing a break or high resistance.
  5. Inspect the motor control board — Look for burn marks, swollen capacitors, or a burning smell. If damaged, the board will need replacing.
  6. Restore power and test a cycle — Plug the dryer back in and run a short cycle to see if E64 returns. If it does, the main control board may need replacing.

FAQ

Can I keep using the dryer if E64 keeps appearing?
It’s best not to. The error usually means the drum motor isn’t getting proper control signals, which can lead to overheating or the dryer stopping mid-cycle unexpectedly.

Will unplugging the dryer overnight reset the error?
A power reset can sometimes clear the code temporarily, but if the underlying wiring or board issue isn’t fixed, E64 will come back within a few cycles.

Is this a DIY-friendly repair?
Reseating connectors and checking wiring is manageable for most homeowners with basic tools. Replacing a control board is also doable but requires care with static-sensitive electronics.
