To reconfigure the controller to factory setting:1) Hold both the "Mode" and "Stop" buttons down while removing the magnetic key.2) While continuing to hold both buttons down, replace the magnetic key. All the lights will light up and "beep".3) Whille continuing to hold both buttons down, press the + button.It should now be reconfigured.I hope this helps
1) adjust the speed sensor see the diagram attached. tight the cable, and clean it.2)test the input voltage motor, if there are the motor need repair.3)test the output voltage from the motor controller, for input voltage motor if there are NOT the motor controller need replace.God bless you
Dear Sir:1) Please unplug the machine2) Put with air gum machine, and pass in all board and circuit for heating.NOT OVERHEATING.3) Wait for 24 hours. if you have some infrared lamps, will be better.NOT OVER EXPOSED.4) Turn ON the machine, and proof, if the problem remain, the board is faulty. and replace.5) However try to RUN the software calibration for better diagnose, troubleshooting, and fix it. see the block diagram attached.God bless you
get a multi meter and check the whole circuit for short or damaged wire --fixya cannot tell you whats damaged or where the short is since unit needs to be physically examined
