How to Replace the Motor on a Frigidaire Washing Machine

The drive motor on Frigidaire EFLS front-load washers is a brushless induction motor mounted at the bottom rear of the machine, connected to the drum via a multi-rib drive belt (137315300) and spring-loaded tensioner. When the motor fails, you typically see the E52 error code (motor communication failure), smell burning during operation, or find the drum will not spin despite the control board attempting to run the cycle.

Motor failure on Frigidaire washers is less common than belt, pump, or lock issues — motors typically last 12-15 years. However, when they do fail, the symptoms are dramatic: burning smell, smoke, or complete inability to spin. This guide covers diagnosis, removal, and installation of the replacement motor.

Before You Start

• Tools needed: Phillips #2 screwdriver, 1/4-inch nut driver, socket wrench (motor mounting bolts), multimeter
• Parts needed: Replacement motor assembly (~$80-$180, model-specific)
• Time required: 45-60 minutes
• Difficulty: Intermediate
• Safety warning: Unplug the washer before any work. Motor capacitors can hold residual charge — do not touch motor terminals for 5 minutes after unplugging.

Step-by-Step Instructions

Step 1: Diagnose the Motor Failure

Before ordering a motor, confirm the failure is in the motor itself and not the control board or wiring:

Remove the rear panel (12-16 Phillips screws). Locate the motor at the bottom center. Disconnect the motor wiring harness. Set multimeter to resistance and test across each pair of motor winding terminals. Expected readings: 2-6 ohms between each winding pair. Infinite reading = open winding (motor burned out). Very low reading (under 1 ohm) = shorted windings.

Also check for physical damage: burn marks on the motor housing, melted plastic on connectors, or a seized shaft (try rotating the motor shaft by hand — it should spin freely).

Step 2: Remove the Drive Belt

With the rear panel off, release the spring-loaded tensioner by pushing its arm toward the motor. Slip the belt off the motor pulley and drum. Set the belt aside — inspect it while you have it off. If it shows wear, replace it along with the motor (belt 137315300, $15-25).

Step 3: Disconnect the Motor

Disconnect all wiring harnesses from the motor. Photograph each connection position first — Frigidaire motors typically have a main power harness and a tachometer (speed sensor) connector.

Remove the motor mounting bolts. Frigidaire front-load motors are secured with 2-4 bolts (typically 10mm or 13mm) that attach the motor bracket to the machine base frame. Support the motor as you remove the last bolt — it weighs 10-15 pounds and will drop if not held.

Slide the motor out from under the machine. Note the motor mounting bracket orientation and any rubber isolator mounts — these dampen vibration and must be transferred to the new motor if not included.

Step 4: Transfer Mounting Hardware

If the new motor does not include the mounting bracket, remove the bracket from the old motor (typically 2-3 bolts) and transfer it to the new motor. Also transfer any rubber isolator mounts, motor pulley (if separate from the motor shaft), and wiring conduit clips.

The motor pulley on most Frigidaire models is press-fit or set-screw mounted on the motor shaft. If replacing the motor requires removing the pulley, mark its position on the shaft (distance from motor body) before removal. The belt alignment depends on the pulley being at the correct height.

Step 5: Install the New Motor

Position the new motor in the same location as the old one. Start all mounting bolts hand-tight before torquing any — this ensures alignment. Tighten bolts evenly in a cross pattern. Reconnect all wiring harnesses — each connector must click into its locking position.

Route the belt around the drum (flat side to drum), then over the motor pulley and tensioner (ribbed side to pulleys). Release the tensioner — it should snap into position holding the belt taut.

Step 6: Test the Installation

Replace the rear panel. Plug in the washer. Run a spin-only cycle (or a normal cycle). Listen for smooth motor operation — no grinding, buzzing, or vibration. The motor should ramp up gradually during spin acceleration. Any metallic scraping means the motor pulley is misaligned with the belt or the motor is hitting the frame.

Verify the E52 error has cleared. If it persists, check the tachometer connector — this speed sensor tells the control board the motor is actually spinning. A loose tachometer connection triggers E52 even with a perfectly good motor.

Troubleshooting Common Issues

• E52 persists after motor replacement: Check the tachometer/speed sensor connector. Also verify the control board connector on the other end of the motor harness is fully seated. In rare cases, the motor control board (separate module on some models) has also failed.
• New motor vibrates excessively: Motor mounting bolts may be loose, rubber isolators may be missing or compressed, or the motor pulley is misaligned with the belt path.
• Belt squeals with new motor: The motor pulley diameter or position may differ slightly. Verify correct part number for your specific model.
• Motor runs but drum does not spin: Belt is not routed correctly or tensioner is not engaged. Verify belt routing with rear panel temporarily off while running.

When to Call a Professional

• If the control board also shows damage (burned components) — a shorted motor can damage the board
• If the motor shaft is seized and the tub/drum assembly needs inspection for related bearing damage
• If you are uncomfortable working near motor capacitors or high-current wiring

FAQ

Q: How do I know if my Frigidaire washer motor is bad? A: E52 error, burning smell, motor hums but does not turn (with belt removed). Test winding resistance — each should read 2-6 ohms.

Q: How do I access the motor? A: Remove rear panel (12-16 Phillips screws). Motor is at bottom center, connected via belt and tensioner.

Q: Can I replace just the motor brushes? A: Frigidaire EFLS front-loaders use brushless induction motors — no brushes to replace. Full motor replacement is required.

Q: How much does a Frigidaire washer motor cost? A: $80-$180 depending on model. DIY saves $150-$300 in professional labor.
