This has been happening for a couple of years sporadically. Over the last 6 months it has started happening at least on a weekly basis. It will even turn the light on and I cannot turn the light off. Sometimes the light goes on and off extremely fast for 5 minutes or more. What part is it that has the problem?

Equipment is Whirlpool double oven RBD305PDS14 built-in. After a very stormy summer 2007, I thought a power surge may have zapped the control board. Problem initially presented on display as error & fault "E6 F2"; simply pressing "Timer Off" would usually clear this error & fault code.
However, some months later, the display would often go completely blank followed by the beep sequence "short-long-short-short-short" (Morse code: dit dah dit dit dit). No error & fault code would appear. Pressing any keypad oven control did not work at all in this condition. When power was cycled at the breaker panel, the usual "PF" with clock display did not appear.
[TURN OVEN POWER OFF AT BREAKER!!!]
After following the excellent information on "how to remove the control panel" posted in this forum, I first tested the "control panel thermal fuse" (refer to the tech sheet that should be behind the control panel once it is removed). It showed a closed circuit.
I turned my attention to the "flexible" keypad connector cable (error & fault code "E6 F2" is a keypad or keypad connector problem; again, refer to tech sheet). The control panel has a board mounted female connector with two tabs that may be gently pulled upward to release the flexible cable.
I cleaned the flexible cable contact area (it seats into the board mounted female connector) carefully with a Q tip and some isopropyl alcohol. I reinserted the flexible cable and gently pressed down on the two tabs (noted above) on the board mounted female connector. VERY GENTLY tug on the flexible cable to insure it is gripped by the connector.
After all of this monkey business, I re-mounted the control panel display panel on the oven and restored power. So far, so good. After applying power, the "PF" with clock display always appears. I am able to set the clock and press "Start". Over functions normally. The clock displays as normal and I no longer observe the problem I described above.
BTW, I noted the incoming 240V has transient suppression (no surge protection, however).
The F3 means there is something wrong in the sensor circuit, sensor/wiring/clock.
Shorted or open oven temperature sensor (RTD):
Solution: Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.
Sometimes I had it where the lamp holder in the oven has a short and then welds the contact on the function switch. If you replace the complete lamp and holder and function switch for the oven. 3 time last year on bellings this happened. To try disconnect the two wire on the lamp holder then if it doesn't trip you no that's it make sure you turn the oven off and don't touch the wires together when u turn back on.
The electronics inside the unit may have just needed to be reset by removing power to it. I can't tell you whether or not it's safe to use. If you are unsure I would suggest having it checked out by an electrician or appliance tech first.
If you are not fitting genuine
elements, this is probably the reason they are failing so quickly.
You will pay a lot more for the genuine article, but they will last a lot longer.
Also make sure the fan is working o/k, as this can cause premature element failure.
please rate my solution.
We've had the same problem. I contacted a local sales room and they contacted their rep who promptly mailed the replacement parts I requested (I'd looked up the part numbers already). Now I'm waiting to find someone who will reasonably do the work.
There is a temperature switch that shuts the power down if the temperature goes too high. This is to prevent a fire if your thermostat sticks on. Sometimes the switch will become weak and open the circuit at too low of a temperature. Replacing the switch should solve your problem.
If you need more assistance, post a comment with the model and s/n of your stove.
