I recently had a problem with my Automotion motorized shade. It has a motorized day shade and night shade. The day shade problem started with it moving down fine but the up switch would move the shade about a 1/2" then stop. Therefore to get the shade up enough to drive required numerous switch operations. Eventually the down function had same problem.
With a call to the factory I was told the motor was bad and they could not sell me a replacement. A search of the forums indicated this is a very common failure with this shade. There are some write-ups on using a modified motor available from another vendor for around $100. I disassembled mine to find out that the reason this is happening is due to high motor current (>2 amps). Turns out there is an electronic circuit that switches off motor voltage when it draws excessive current. This circuit is within the motor tube. I have found the fault is with the motor itself and it can be repaired just by removing the motor from the drive gear end take it apart and clean up the brushes and commutator. I have done this. It takes less than 2 hours (once you get the shade assembly out of the MH). After the repair the current draw is less than 400mA. If you have one that needs repair and need help send me a message.
