Have Fridgidaire stove, says on back 3 wire AC only. Recently I moved, outlet for stove is 4 wire, I changed plug from 3 wire to 4 wire plug. Seems everything works fine, problem is with display board. Clock is dim, and I cannot set temperature for baking display, does not light up. Is board faulty, or not working because I rewired from 3 to 4 wire? Your help would be greatly appreciated.

1Sounds like you wired it wrong. Need: picture of receptacle, picture of wires from cord where they attach to stove. Get a multimeter and report voltage readings between every pair of holes in the receptacle.– manassehkatz-Moving 2 CodidactOct 15, 2021 at 19:48

14-wire is vastly safer and should not affect anything.– Harper - Reinstate MonicaOct 15, 2021 at 20:44

1What model is this stove of yours? Also, can you post photos of any wiring diagrams on the appliance, and how the cord is wired to the range?– ThreePhaseEelOct 16, 2021 at 0:23

It's possible you've miswired the stove and put the neutral on a hot terminal. Most likely the stoves power supply for the computer derives it's power from a hot to neutral connection, but not necessarily. You could either be over volting or under volting the power supply. Recheck your wiring and make sure you have the correct colors matched up.
Also, make sure you remove the copper bonding strap from the neutral conductor. And make sure the white wire is on that terminal.
