The E44 error on your Frigidaire washing machine means the main control board has lost communication with the motor control unit (MCU). This usually points to a wiring or connector problem, though a faulty board can also be the cause.

Error code E44
Meaning Communication failure between the main control board and the motor control unit (MCU)
Severity Medium — the washer usually won’t start or complete a cycle until this is fixed
Time to fix 15–45 minutes
Tools needed Multimeter, screwdriver (Phillips and flathead)

What the E44 error means

Frigidaire washing machines use two separate boards to run the machine: a main control board that manages the display and cycle selection, and a motor control unit (MCU) that drives the drum motor. When these two boards can’t talk to each other, the washer throws an E44 code and stops the cycle to prevent damage.

This is a communication fault, not necessarily a broken motor. In most cases it comes down to a loose connector, a damaged wire, or a harness that’s come unseated from vibration during use.

Common causes

  • Loose or disconnected wiring harness between the main control board and the MCU
  • Corroded or damaged connector pins from moisture or age
  • A blown fuse or failed component on the motor control board
  • Main control board malfunction preventing it from reading MCU signals
  • A power surge or brownout that scrambled the board’s communication
  • Loose ground wire causing electrical interference between boards

How to fix the E44 error

  1. Power cycle the washer: Unplug the machine for 5 minutes, then plug it back in. This clears temporary faults and resets the communication link between boards.
  2. Check the wiring harness: Unplug the washer, remove the back or console panel, and inspect the harness connecting the main control board to the MCU. Look for loose plugs, frayed wires, or burnt connectors.
  3. Reseat all connectors: Disconnect and firmly reconnect every plug on both boards. A connector that isn’t fully seated is one of the most common causes of this code.
  4. Test the MCU with a multimeter: Check for continuity and correct voltage output on the motor control board per your model’s service sheet. No output usually means the board has failed.
  5. Inspect the main control board: Look for visible burn marks, bulging capacitors, or corrosion. A damaged board will need replacing.
  6. Replace the faulty board: If wiring checks out but the error returns, replace the MCU or main control board — whichever tested faulty — using the correct part number for your model.

FAQ

Can I fix the E44 error myself?
Yes, in many cases. Checking and reseating the wiring harness is a simple DIY step that resolves the issue without needing new parts. Board replacement is also doable with basic tools if you’re comfortable working with appliance electronics.

Will unplugging the washer clear the E44 code permanently?
It can clear the code temporarily, but if the underlying wiring or board issue isn’t fixed, the error will come back. Power cycling is a good first troubleshooting step, not a permanent fix.

How much does it cost to fix an E44 error?
If it’s a loose connector, it costs nothing but your time. If a board needs replacing, parts typically run from £60–£180 depending on the model, plus labour if you hire a technician.
