Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

Samsung Microwave Turntable Motor Replacement - Signs & How-To

Q: What does Samsung Microwave Turntable Motor Replacement - Signs & How-To mean?

Glass tray won't rotate, motor hums or is silent, tray spins intermittently, or couplers are cracked. Replacing the turntable motor restores rotation.

Q: How do I fix Samsung Microwave Turntable Motor Replacement - Signs & How-To?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Samsung Microwave Turntable Motor Replacement — What This Part Does

The turntable motor sits underneath the microwave cavity and drives a small coupler that connects to the glass tray support system. When you start the microwave, this motor spins the tray continuously so food heats evenly. Over time the motor bearings wear out, the internal windings fail, or food debris jams the coupler, causing the tray to stop rotating. When the motor itself is defective, replacing it restores proper tray motion and even heating.

Signs It Needs Replacing

Glass tray does not rotate at all The tray sits still while the microwave runs, meaning the motor is not transferring motion to the coupler or the motor has failed entirely.
Motor hums but tray won’t spin You hear a buzzing or humming noise from below the cavity, indicating the motor is receiving power but the coupler is cracked or the motor shaft is jammed.
Motor is silent when microwave runs No sound comes from the turntable area, suggesting the motor has burned out or the electrical connector is loose or disconnected.
Tray spins intermittently or stops mid-cycle The tray turns for a few seconds then stops, which points to a motor on the verge of complete failure or a damaged coupler slipping on the motor shaft.
Visible cracks or wear on the drive coupler The plastic coupler that sits on the motor shaft shows fractures or spins freely without engaging the tray support, a common mechanical failure that prevents rotation.
Debris or food buildup in the roller path Crumbs or spills under the roller ring jam the rollers or bind the tray, causing extra load that can burn out the motor over time.

How to Replace It

Unplug the microwave completely from the wall outlet and wait at least two minutes to allow internal capacitors to discharge.
Open the microwave door and remove the glass tray, then lift out the roller ring and inspect both for cracks, debris, or damage.
Clean the cavity floor and roller path thoroughly to remove any food or grease that could bind the tray or rollers.
Inspect the drive coupler on the cavity floor for cracks or free spinning, and replace it if damaged (Samsung part DE67-00236A is a common genuine coupler).
Flip the microwave over or remove the bottom access panel by unscrewing the base screws, depending on your model, to expose the turntable motor mounted underneath the cavity.
Disconnect the motor wire harness by pulling the connector straight off, then remove the two or three screws holding the motor bracket to the cavity floor.
Pull the old motor out, noting the orientation of the shaft and coupler, and install the new turntable motor (common Samsung parts are DE31-10172C or DE3110170B) with the same shaft alignment.
Reconnect the motor wire harness, replace the mounting screws, and reinstall the bottom panel or flip the microwave upright.
Reinstall the roller ring and glass tray inside the cavity, plug the microwave back in, and run a short 15-second test cycle to verify the tray rotates smoothly before closing the door.

The Part You Need

When to Call a Pro

If you are uncomfortable working near high-voltage capacitors inside the microwave cabinet, or if replacing the motor and coupler does not restore tray rotation, call a qualified appliance technician. Microwaves store lethal voltage even when unplugged, and a persistent no-rotation problem may indicate a control board or wiring fault that requires diagnostic equipment and safety training to resolve safely.
