PSA: Watch out for counterfeit control boards on Amazon
I ordered a replacement control board for a Whirlpool dishwasher off Amazon last week because the OEM part was on backorder for 3 weeks. The board showed up in a plain box with no branding, but the model number matched. I installed it, fired it up, and the dishwasher ran the cycle but never heated the water. Checked the heating element and thermistor, both were fine. Turns out the board had a tiny relay swapped for a cheaper one that couldn't handle the load. Lost 2 hours of labor trouble shooting and had to order the genuine part from a local supplier in Phoenix. Has anyone else run into fake parts from online sellers, and how do you spot them before installation?
