After reading many forums i have yet to find one for this...
The knob used by the display rotates and depresses but the display of change is very slow. For example, as I watch the temp selection and rotation of the knob it can take 4-5 rotations to go up 10 degrees.
Worse is when I attempt to level the bed and use the knob to raise the bed. Each rotation moves it up only about 2mm. Then it drops at the end of each rotation by about 1mm. This mean that it can take almost 30+ rotations before it reaches the top.
I have not yet reseated the knob and can not tell if it is mechanical or not.
Thanks for any assistance possible.
