Dunkermotoren D259 CCW Repair

Repairing Dunkermotoren D259, limit switch defective

The Dunkermotor D259 (counter-clockwise, CCW ) is a drive unit for blinds and venetian blinds, commonly used in many external blinds and venetian blinds, including Warema systems. It is the successor to the D249 and functions identically. If your venetian blind no longer stops reliably at the set end position or exceeds it, the limit switch is almost always defective. We repair this type of damage for a fixed price.

Typical symptoms of a defective limit switch

• The end position can no longer be set or saved.
• The venetian blind stops before reaching the set end position.
• The drive does not stop and continues past the end position until it reaches the stop.
• After being driven over, the curtain is blocked at the shut-off mushroom; in the worst case, the textile bands are torn.

Our guide to setting the end positions shows you how to correctly adjust the limit switches and distinguish between an operating error and a genuine defect. Repair without an electrician, thanks to the Hirschmann connector: Your Dunkermotor D259 is equipped with a Hirschmann connector (STAK/STAS), a coded and touch-proof plug connection. Simply unplug the motor, send it in, and then plug the repaired motor back in – no wiring or electrician required. The mounting bracket and shaft adapter remain in place. For safety, switch off the corresponding fuse before disconnecting.
