After Self-Cleaning the lower oven wont heat up!

Never ever use the Self Clean feature. All it exists to do is to keep the makers in a steady stream of sales of spares. The temperature is 800 to 925'F. The parts can't handle it.

Try turning off at the breaker overnight to reset.

Whirlpool have the self clean latch assembly solenoid go bad and wont return back to unlock the switch to tell the control is is no longer in self clean. Replace the self clean latch assembly or make sure the switch on the assembly is in the non self clean mode, If the oven starts working then you know the problem if it still doesn't work then there may be other issues.

Ours have also stopped working (both top and bottom). Bought in 2003 so only 8 yrs old. Getting technician in to fix. Will post solution. Also whenever oven is heated up the display panel fades and is not visible (has been doing this for a couple of years)

Hello,

An electric oven is a great oven choice because of the advanced self-cleaning feature often available on certain models. A self-cleaning oven uses high temperatures to clean crusty baking spills and splatters and free its owner from having to use harsh chemicals to clean his oven. The following 4 steps lay out how a self-cleaning oven works.

Step 1 - Setting the Self Cleaning Mode
Depending on the style and brand of oven you own, you start the self-cleaning cycle by setting the oven's operating dial to "Clean," a function that can be as simple as setting a timer knob or pushing one or two buttons.

Step 2 - Cleaning Cycle
Once you have set the self-cleaning cycle, the oven coils-both lower and upper--will begin to heat. These self-cleaning ovens are protected from high oven temperatures damage by heavy insulation installed in their walls and door during the manufacturing process.

Step 3 - Automatic Door Lock
When the oven reaches a pre-determined temperature, the lock on the oven door engages, preventing anyone from opening the door until the oven temperature has cooled.

Step 4 - Removing Residual Ashes
Once the cleaning process is completed, including cooling, you can then remove the residual ash by wiping the bottom oven surface with a damp cloth or sponge.


Hope this helpout

NO IN ORDER TO ENGAGE IN SELF CLEANING THE LOCK MUST FIRST ENGAGE. DOOR LOCK ASSEMBLY FAILURE

That depends if the oven is electric or gas.

If it is electric, it can be heating element, temp probe, or control knob/buttons, board and wiring.

If it is gas it can be the igniter (check spark) , the thermostat, the safety valve that prevents accidental gas flow, or the control.

If the oven has self cleaning cycle, check that it is not stuck on self cleaning, try unplugging for a while and restarting self cleaning cycle in that case.

Check also What is wrong with your Range/Stove/Oven?

There is a overload thermostat on the rear of the oven that will have to be replaced.
Self cleaning features are not recommended by most appliance technicians.
Self cleaning causes parts to fail often.

I have a Whirlpool MOD. RBS275PDB17 single electric self-cleaning oven; although the manual is generic, it specifies, "When the cycle is completed and the oven cools, "End" will appear on the lower oven display and "LOCKED' will disappear" and "To Stop Self-Clean any time: Press UPPER/OFF, LOWER/OFF or OFF/CANCEL. If the oven temperature is too high, the door will remain locked. It will not unlock until the oven cools." Has your oven had time to cool?
