Troubleshoot common centrifuge

1. 800 centrifuge (no timing function, adjustable speed)

1. It takes a long time, but the rotation is weak or it can be turned to the highest speed.

Solution: Need to replace 80-1 carbon brush

2. It takes a long time, but does not turn

Solution: There are three situations to consider

(1) Check if the power plug is plugged in, or whether it is energized (the power cord is common to the desktop computer power cord)

(2) If there is no problem with the power cord, the fuse (1A) may be burnt out. Try to replace the fuse. There are two black cylinders on the right side of the power plug. Use a cross screwdriver to unscrew and replace.

(3) If the above two problems are not, you need to consider the circuit board damage, or return to the factory for repair or send the circuit board for installation by a professional electrician.
