Lower oven not heating

Isn't the upper element the grilled? I don't think it is controlled by the oven thermostat.

have controller checked

We have here a video showing how you can check the temperature sensor
We also here the parts diagram of your model

try turning your breaker off for 20 minutes, then try it again,, if this does not help it could have burnt out a element or the main board has went out,,, also make for sere you are getting the full 220 volts to the unit,, this will involve taking the unit out

try unpulg it

Hello!
This blank display is a common control board problem. If the buttons beep when pressed, then the control board is getting adequate power. If the buttons beep.. and your oven light still turns on when the oven door is open.. this a text book control board failure. We at Fixyourboard.com can solve this problem for you, and back the remanufacture with a two year warranty.

There is an element that circles the rear fan, this is the common element and the most powerful.
Once you have the lid off, it's quick to test continuity on all elements.
Hope this helps

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

Try to identify which oven you have and try to get a manual from the same source

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.
