Kenneth C Oxford , CT September 06, 2016 Appliance: Maytag 30" Free Standing Electric Range Convection MER8772WB1 Maytag Range Mer8772wb1: Oven stopped heating 2 error codes came up. How to replace Electronic Control Board. I have a Maytag range made by Whirlpool go figure, about 7 years old, anyway I turned on the oven to preheat to 350 to warm food for a party and came back to find the oven off and the display read feature not available. Odd never saw that before. The oven would not come back on. As I couldn't do anything with the oven I went out to the breaker panel and shut the off the breaker 50 amp for the range. The next day after work I turned the breaker on and the oven was working. Odd again. I found the tech sheet on the top left rear of the range and got the model and serial numbers from the bottom frame in front left side behind the pull out drawer. Reading the tech sheet I ran the auto test and 2 fault codes came up. F6 E1 and F2 E0. Runaway temp and keypad disconnect. Only 2 items would cause that so I ordered the electronic control board and the oven temp sensor just because of age. Went back and shut off the power to the range and ordered the parts. The parts arrived within 2 days. It took about 20 minuets and a Phillips screwdriver to change both pieces. Be careful not to create any static charge when handling the board only touch the plastic sides. Turned the breaker back on and ran the auto test function and no faults detected the oven is working normal again. 11 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
