My whirpool GR448LXPS stove display board just went out and now the only way you can get the display to come back on is to turn one of the burners on. Once on you can turn the oven on like normal as well as the burners but nothing heats up. Turn the one burner off and the display goes blank again. Any suggestions?? Eric

You may have a power problem so I would start there, see below.
It could be the L1 side of the line is not there. When you turn on an element the L2 side of the line feeds through the element’s infinite switch and this then powers the control board. Also no elements will heat as you do not have the 240 volts.
Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.
Check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Do this with the heater off and on.
Be careful as 240 volts is lethal !!!
