Air Compressor problem

Did the auto-shutoff work before it quited? I mean, did the motor turned off whenever you are NOT spraying? If not, the auto-shutoff is defective and the cause of overheating. I thought that you found out about the 3-way switch and solved your problem from the earlier post. After all, you need to send it back to the dealer. What a bump.

I wonder whether the newer DA400R is inferior to the older model which was made in Taiwan? My DA400 does NOT have a reset switch, but never got overheat either. It is only slightly warm to the touch even after long airbrushing session.

I would just request an RMA from the dealer and return the compressor. The compressor should not have overheated if the auto-on/off is working. The manual has this description of the thermal protection feature:

Since the thermal protector is part of the motor and the only way to reset it is to unplug the unit. When it does not restart, there is not much to do. Again, it should not overheat in normal use. I will not keep this unit if it overheats for no obvious reason. Mine will not even get hot to the touch. Good luck in getting a quick solution to your problem.
