Before troubleshooting, forst, please switch off, and disconnect the power cable, and then open the
top cover of warmer module and the back cover of column. And then connect the power cable and turn
onthe switch, at the same time, make sure that power +5V, +12V of controller, element, and all cables
are in good condition.In working state, press Up Key and Air mode Key , you can find the isolated
temperature and air flow temperarture in the air and set temperature indicator respectively. So it is easy
for service man to find the cause of trouble.
