Find the frame’s brand and model first. It is usually on a label under the desktop or on the control box. A manufacturer’s own replacement part is always the safest fit; check whether one is still sold before looking at anything generic.
Measure the drive shaft on the old motor. On many frames the motor turns a hexagonal shaft that runs into the lifting column. Its size decides whether a replacement can engage at all — the generic 24 V kit in the standing desk parts hub is sold in 8 mm and 6 mm hexagon-hole versions. A caliper across the flats of the shaft, or the hole on the old motor, gives the number.
Match the voltage, the connector and the controller. Note the voltage on the old motor or power supply, and look at the plug between the motor and the control box: a connector that looks the same across frame generations is not necessarily wired the same. A kit that ships with its own controller and adapter, as the generic one does, sidesteps the mismatch but replaces the original buttons and presets.
Check the force if a general-purpose actuator is involved. Linear actuators sold for recliners or TV lifts publish a force in newtons and a stroke in millimeters; neither is a desk rating, and a stroke shorter than the column’s travel limits the height range. Compare against the original motor’s figures, not against the weight on the desk.
Price a whole frame before buying parts. The motor kit reads about $76 on Amazon.com; the ErGear electric frame, about $140 without a top, brings a new motor, a controller with four presets and a five-year frame warranty. If more than the motor is failing, the frame is often the better repair.
Test under a light load first. Before putting monitors back on, run the desk through its full range empty and check that it lifts smoothly and stays level, then reload it gradually.

What buyers ask us first
Can I use a generic motor instead of the manufacturer's part?
Sometimes. A generic kit can work if its drive-shaft fitting, voltage and controller match the frame; the 24 V kit in this site's standing desk parts hub is sold in 8 mm and 6 mm hexagon-hole versions for exactly that reason. It names no frame brand, so the measurement on your old motor is what decides it.
Is it worth replacing the whole frame instead?
Price both before deciding. The motor kit in the parts hub reads about $76 on Amazon.com; the ErGear electric frame reads about $140 without a top, with four presets and a five-year frame warranty. When the motor, controller and control box are all suspect, a frame can cost little more than the parts.
Is a manual crank frame a good alternative?
It removes the motor and electronics entirely, at the cost of cranking and slower height changes. The manual frame in the parts hub is sold only in Europe; in the US, the choice on this shelf is a replacement motor or a new electric frame.
