Where to buy this item - Bosch HBN 7052 GB Stainless Steel Electric Double Oven

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).

Replacing an oven element is quite simple that almost anyone can do it.

1. First pull the oven away from the wall and unplug it.
2. Next, remove the rear panel from the oven.
3. Now disconnect the element from the wires that power it, they should pull straight off of the element.
4. Remove any screws that might be holding the element in place, check both in the oven and on the back. It depends on the make and model where the screws may be.
5. Last, remove the element by pulling it out through the heating chamber, and replace with the new element. Simple as that.

For replacement parts, check repairclinic.com which I recommend, otherwise local stores may have what you need or the manufacturer themselves.
Congrats, you have just learned how to replace an element.
