Yes i have done that i keep 2 of them in stock that is a big problem with them along with the igbt and diode taking out the board. Try to keep most of the electronics in stock. The company i work for makes pickles so you can imagine the environment there in wet, salt water, vinegar,ect.. but i did run into a problem a few years back where everything pointed to the h bridge board and eventually figured out i had 3 defective boards in a row. Thanks
