Power Sunblind Issues

[///Sniper535]

What will cause the down function to have intermitent hiccups. Meaning when I push the down button it doesn't go down, just clicks once then again after about 10 seconds, then one day or a minute later it goes down if you push the button as if nothing happened.

check the switch, clean it, check if there is power. The clicking could be overload, check wiring diagrams. On the German forum I read that some had to repair the control module.

Is it working when te,peratures are colder or warmer? Because that could have an influence on the power rquirement for the motor. The electric sunblind has no limit switch, it switches off when the amp rises and with some seconds delay. If temp is warm, material expands and that could cause more power requirement, or the other way round.

it has been really hot when it quits on me... I forgot to mention that.

So that could mean overload when it is hot and material expands and then it jams. Download this retrofit instruction, English language is further down

Try to ease the tension.
