Self test failure------the fan stirring is spinning, but no RPMs were measured

Hi, I run a self-test, and I got some problems. Something were wrong with stirring self-test(see the images). The fan is spinning, but no RPMs were measured. I don’t known how to deal with them. What I can do next?



Hi @yangnancy678

We have some troubleshooting steps here, have you tried those yet? The most common problem is that the magnets are not close enough to the bottom of the top-vial-holder.

I have tried those steps, but it still doesn’t work. Are these essential components?(images) Will it affect the operation of the device if they are removed?


They are just spacers - I believe that they can be removed. Just keep the top of the fan assembly away from the top-vial-holder to avoid rubbing. You may need to glue the fan assembly down, else the magnets may make it lift off the baes.
