So I rechecked the leads from the smoke fan motor to the board and they both have continuity.
Based on all of this I would like to send you the board for testing and repair (if possible). What is the best way to send this to you (address, etc.) and could you give me an idea of potential costs? Can I send you the boards only to minimize labor, packaging and shipping costs?
One other quick question though. You mentioned that failures like this can occur if the smoke fan motor is bad and draws more than about 40 milliamps at 5 VDC (I am not able to test the motor right now--need a 5VDC power supply which I can borrow from a friend sometime in the next week or so). When you refer to failures like this (with the information that you have at this point) are you thinking that this is a fan motor issue due to high amp draw or a board or FET failure caused by a high amp draw from the smoke fan motor? Either way, it seems like in addition to having you test the board I need to test the fan motor for amp draw and if it is high replace the motor.
Thank you again for all of your help!!
