The E67 error on your Frigidaire washing machine means the main control board has lost communication with the motor control unit. This usually points to a wiring or connector issue rather than a broken part, so checking the connections first can save you a service call.

Error code E67
Meaning Communication failure between the main control board and the motor control unit
Severity Medium — the washer won’t run a cycle until it’s resolved, but it’s often a simple wiring fix
Time to fix 15–45 minutes
Tools needed Multimeter, screwdriver (Phillips and flathead)

What the E67 error means

Frigidaire front load washers rely on constant communication between the main control board and the motor control unit to run the drum motor correctly. When that signal drops or gets interrupted, the machine throws the E67 code and halts the cycle as a safety measure. It’s similar in nature to other appliance communication faults, such as the Frigidaire EF Error Code seen on refrigerators, where a break in the signal path triggers a protective error rather than a true component failure.

Common causes

  • Loose or disconnected wiring harness between the main control board and motor control unit
  • Corroded or damaged connector pins from moisture exposure
  • A faulty motor control unit that can’t send or receive signals
  • Failing main control board unable to process communication
  • Power surge or brief outage that disrupted the control system mid-cycle
  • Loose ground wire causing electrical interference on the signal line

How to fix the E67 error

  1. Power cycle the washer: Unplug the machine for 60 seconds, then plug it back in. This resets the control boards and clears temporary communication glitches.
  2. Check the wiring harness: Unplug the washer, remove the rear or console panel, and inspect the wiring between the main control board and motor control unit for loose or disconnected connectors.
  3. Inspect connector pins: Look for corrosion, bent pins, or discoloration on the connectors. Clean lightly with electrical contact cleaner if needed, or replace the harness if damaged.
  4. Test wiring continuity: Use a multimeter to check for continuity along the harness wires. A break in continuity means the harness needs replacing.
  5. Reseat all connections firmly: Disconnect and firmly reconnect each connector along the communication path, making sure they click fully into place.
  6. Call a technician if the error persists: If wiring checks out fine, the motor control unit or main control board itself may need replacing, which is best handled by a qualified appliance repair professional.

FAQ

Can I still use my washer with an E67 error showing?
No. The washer won’t start or complete a cycle until the communication fault is cleared, since the motor can’t be safely controlled.

Will unplugging the washer fix E67 permanently?
Sometimes. If the cause was a brief power surge or software glitch, a reset clears it. If it returns quickly, there’s likely a wiring or component fault that needs attention.

Is E67 expensive to repair?
Often it’s a low-cost fix involving a loose connector or damaged harness. It only becomes costly if the main control board or motor control unit needs full replacement.
