Compatibility and replacement guidance

Match the exact ML18-017B reference, including the B suffix, 333 mm stroke, 139 mm closed and 472 mm extended mounting lengths, fixing ends and available clearance. Other ML18 motors are not automatically interchangeable. If unsure, send CouchGuard clear photos of the original label, full motor, mounting points and plugs, together with your measurements.

A non-moving chair does not by itself confirm motor failure; the switch, power supply, cables or mechanism may also need checking. Disconnect mains power and any battery supply before replacement. Keep clear of moving mechanisms and use a qualified repairer if the chair cannot be safely supported. Do not modify plugs or connect directly to mains power. Follow the label duty cycle of 0.5 minute running followed by 4 minutes off.

• Compare the connector type, dimensions and mounting points with the product listing.
• Check the product description and compatibility guidance carefully.
