Somfy LT50/60 tubular motor repair | Emergency hand crank NHK CSI RDO | Roller gate
Somfy LT50/60 tubular motor repair - specialist company for roller doors & awnings with an emergency hand crank (NHK / CSI / RDO)
Important note – repair service
This offer is exclusively a repair service. No tubular motor is sold.
The subject of the contract is the professional repair of the tubular motor sent in by the customer. The motor sent in remains the property of the customer at all times.
By sending in the motor, the customer commissions the repair service and demands that this begins before the cancellation period expires.
Your Somfy tubular motor tells:
“I am the motor you can rely on – even when the power goes out.”
“I use my emergency hand crank to keep the roller shutter moving and protect what lies behind it.”
“With Thomas Reh I regained my strength and security – ready for the next goal.”
The reliable Somfy motor with emergency hand crank
The LT series from Somfy in the LT50 and LT60 variants is one of the robust tubular motors for roller shutters and large awnings. Its integrated emergency hand crank (NHK) enables manual opening or closing even in the event of a power failure - a crucial safety advantage in commercial and private areas.
The CSI and RDO versions have additional mechanisms for power transmission and locking protection, which ensure precise movement and high operational safety. These motors are particularly durable and can in most cases be professionally refurbished and put back into operation.
Advantages compared to a new purchase
- Sustainable: Environmentally friendly repairs instead of buying new – proven mechanics remain in use.
- Cost-saving: Repair cheaper than buying new, no conversion or adjustment of the gate control required.
- Can be operated manually: Thanks to the integrated emergency hand crank, the roller shutter remains functional even in the event of a power failure - without any loss of safety.
- Reliable: Technology or electronics – robust and long-term stable, tested for perfect function.
- Compatible: Suitable for roller shutters and awnings with NHK, CSI, RDO or Sunea io CSI drive systems.
This repair applies to the following error patterns
- Roller shutter only opens partially or requires manual assistance to raise
- The awning extends, but only retracts with slight pressure
- Motor runs, hums or responds with a delay
- Clear “clack” noise when changing direction
Repair process
- An order: Select the appropriate motor model and complete the order.
- Sending: Send in the defective motor properly packaged (shipping costs for buyer).
- Repair: Professional repairs within 1-2 working days.
- Return shipping: Return shipping is generally possible, but only at the usual package costs if the motor sent in is packaged in a stable, space-saving and safe manner for transport. In the case of bulky or inadequate packaging (e.g. tube or bulky goods boxes), I reserve the right to invoice the additional costs of return shipping separately.
Processing time & shipping time
- The motor will be repaired no later than the following working day after receipt of the goods.
- The return will take place within another working day.
- Processing time may vary depending on platform and shipping method; exact information will be provided when the order is placed.

Tubular motor fault diagnosis
Troubleshooting promise for tubular motors
Is your tubular motor no longer responding, only moving briefly or acknowledging it with a typical “clack” noise? Not every fault means the unit is beyond economical repair.In many cases, motors can be sent in and repaired directly. However, if the error patterns are unclear or borderline, I recommend a brief preliminary phone consultation. This makes it possible to assess in advance whether a repair seems realistic or whether there may be a total loss.
Following prior consultation, my fault-diagnosis guarantee applies: I carefully assess the submitted tubular motor for repairability. If a repair is technically impractical or not economically viable, you will only be charged the agreed fault-diagnosis fee of €35 plus possible return shipping.
In any case, you will receive a transparent professional assessment and then decide for yourself how to proceed.
Frequently asked questions about tubular motor diagnosis
Do I have to call before each submission?
No. Many motors can be sent in directly. However, if the error patterns are unclear or unusual, a telephone consultation is recommended.When does the fault-diagnosis guarantee apply?
The promise applies after prior agreement if repairability is to be tested.What happens in the event of a total loss?
If a repair is not worthwhile, you will only be charged the fault-diagnosis fee of €35 plus possible return shipping.Adjustment and reset cable rental for motors
Resetting a tubular motor and setting the limit positions – optional adjustment cable rental
To restore the factory settings or readjust the limit positions, many 230 V tubular motors may require an adjustment cable. This is particularly useful when the reset sequence has to be activated at the circuit breaker (fuse) and the motor is neither visible nor within hearing distance.
Many drives confirm the reset with a clicking sound or a brief movement of the motor. A universal adjustment and reset cable available for rental lets you carry out commissioning or resetting in a more controlled manner without repeatedly moving between the motor and the fuse box.
The rental cable is not included with this motor offer, but can be ordered separately from the shop, subject to availability.

Gern immer wieder 😊.
Jemanden wie Herrn und Frau Reh heutzutage zu finden ist fast unmöglich … Ich kann die Beiden nur wärmstens empfehlen.
