What tool do I nead to unscrew thr screws that hold the cover to the heating element in a zannussi integrated oven?

<p>Hello,<span> </span><br /> <p> <br> <p>I understand that you oven element is not heating up.<br> <p> <br> <p>The easiest way to tell if it is the element is to check the element itself you will need a few tools to do this one of which is a <b>multi meter with continuity</B>.<br> <p> <br> <p><b>Testing Element:</B><br> <p> <br> <ol> <li><b>Shut off power</B> to the unit this can be accomplished by flipping the breaker or unplugging the unit from the wall.</LI> <li>Remove the rear panel of the Range (on freestanding ranges), on wall ovens you may be able to remove the screws that hold the burner in place at the back and pull the element and wires forward (Be careful not to let the wires go back in side the wall as you will have to pull the oven out to reconnect the element)</LI> <li>Remove the wires that are attached to the terminals on the element </LI> <li>Use your continuity tester and place one lead on each terminal if no continuity the element must be replaced. (If tests good need to test oven switch)</LI> <li>To replace the element do all of the above and remove the oven racks, unscrew the bracket that holds the element in place at the back inside of the oven, pull the element out and replace with the new one.</LI></OL> <p> <br> <p><b>However, do not remove the element until you have the replacement as reenergizing the unit with wires unplugged can cause electrical arching (direct short). </B><br> <p> <br> <p><span> </SPAN>Thank you for choosing FixYa.com<br> <p> <br><span>Justin </SPAN>
