Marcia E P C Beach , FL December 15, 2024 Appliance: Whirlpool Washer WTW4816FW3 Whirlpool Washer Wtw4816fw3: Bad motherboard washing machine. How to replace Electronic Control Board. Replaced the motherboard. Caution - ordering overnight from Appliance Parts Pro does not mean overnight. It means when they decide to ship you the part (In my case, three days later), it will be overnight. Very disappoint by this. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
