dishwasher would not run

called Sears as unit only ran some times...service man came and it ran...$125...said was most likely the control panel and it would be and additional $325 for him to get the part and come back and install...told him I think I can install if it stops again...it failed about a week later and would not start...went to PartSelect to purchase the panel...whle looking up the part I read the section on analyzing the problem in "free repair help" and noted that 65% of the time it is the fuse...I checked the fuse for continuity and found none...figured why not try a $15 part first...it came...followed the easy instructions...dishwasher works great...saved over $300...thanks PartSelect for being more than just a parts warehouse
