When I turn on the oven or broiler, fan comes on and display is illuminated, but oven never begins to heat up.
Most likely the thermal safety was activated and needs to be reset if not, you have a bad relay board.
SOURCE: Our oven's heating elements will not come on althought the display seems to work correctly.
Wekiwa, your TCO, (thermal cutout) probably opened during the high temps in self clean. You will have to remove the back panel and replace it. It should be just under the vent back there. Part number 4450934. You can ohm it out first to make sure, it will show open (no continuity) if bad. This is an easy job, won't take you that long. Kill power to the range before going back there. In doing a little more research on your model, I see there was a service flash where they recomend moving the TCO over to one side so the cleaning cycle doesn't affect the TCO. This may be covered by Whirlpool. You might want to call them and inquire. Catriver..post back.

Found the fault. It's the heat ring in the main oven. MAKE SURE THE MAINS POWER IS OFF PRIOR TO COMMENCING THIS WORK!!!!! 1.Simply remove the four screws that fix the fan surround in the main oven. 2.Remove the rear cover fixing screws and remove the rear cover. ( the cable passes through this so just rest it to one side ). 3.Remove the two push on spade connectors from the heater element ( positioned just down and to the right of the fan assembly ). 4.Remove the four heater element fixing screws from inside the main oven. 5. The tricky bit. . . There is one more fixing at the top of the fan in the main oven. I could not get the fan off its spindle, but the next step sorted this out. 6.Remove the three fan fixings from the rear of the oven. This allows the fan to wobble/move enough in the oven to remove the final heater fixing screw at the top of the fan. 7.Pull the heater element into the main oven. No doubt it has a very grey and flakey appearance to part of it! 8.Buy a new one and replace it in reverse order, remembering to replace all fixing screws as you go. 9. If you forget which way the cables on the heater element go, the one with the red marks on it goes to the left as you look at the back of the oven from the outside. ( nearest the fan assembly ) I know this all looks a bit long winded, but it really is quite simple if you follow the notes above! Hope this helps someone. Might just save a ridiculous call out charge from the professionals!!!! Best of luck, Keith.

f the oven doesn't heat and the on-off light works, test the appliance controls, motor,
and heating element .
SOURCE: Wont' heat in broil or bake
check incoming electric first, pull it out and gain access to main wire terminal, With multimeter set to at least 250v AC , check your power across the wiring as such. black to white (110v), red to white(110v) and then black to red 230v. if that ok ok turn, then start ckin elements for continuty also there might be a thermostat( usually an 1 in. round component with 2 wires located right inbetween the elements that has gone bad, will show no continuity. ck that before electronic control the fact that its clickin sounds like the relays are workin properly
