    The cover is secured by a strange type of "tamper proof" screw - sort of a half hex head. Where can I buy this tool?

The screws used are tamper proof torx 20 any hardware shop can supply you they are often included with electric drills etc as well remove all back panel screws this will give you access to cooling fans and all elements remove top for access to stata and neons etc.

hope this helps

Disconnect the power first, then remove cover. I am assuming that the elements are not heating up. What is the problem you are having if it is not this?

How do you remove the moulded Hidden Bake Element from the inside whirlpool ceramic range accubake system

first, remove power from the unit before doing ANYTHING! second, remove the back cover of the machine, this will expose another smaller panel with 4-6 screws in it running along the bottom edge across the back. after removing the screws you will have to gently BEND the panel down until you can see the wiring leading to the hidden bake element. cut the insulation covering the back of the element... be sure new element is placed in the exact location of the old one to avoid shorting the bake terminals to the metal cover, then reverse the removal process...

What's the wiring diagram for a GE wall Ovens digital readout

There should be a diagram somewhere on the oven. Usually on the top or back or if not, inside the terminal block cover where the electrical supply wires go into the oven. Make sure its turned OFF before you remove any covers.

Have a bulb broken off inside socket in gas oven..cannot remove..need help

power down at the breaker or unplug the oven,then if possible you can remove the lamp cover and shell from the rear oven wall,then most lamp bases have spade terminal connections unplug these remove the whole lamp base with the broken lamp,remove the broken bulb base,then check the center power tab inside the lamp base to make sure it isn't flattened out too much,otherwise carefully bend it upwards to make sure it makes contact with the bulbs base then re-insert the terminal connections and new bulb into the opening at the rear of oven,then replace the bulb,but,do not over tighten new bulb as this leads to non operation due to heating

My Oven does not turn on but the broiler does. The stove top works as well and it will clean. Its only the oven that does not work, but again it will broil.

It appears your element has failed in this instance.

This advice is on how to replace a bad element on kitchen ranges that utilize ELECTRIC heating elements for baking and broiling.
1. UNPLUG the range and remove the rear panel. Dangerous voltages are still present with the range turned off. The rear panel is in close proximity to the input power terminal block & shock hazard and/or equipment hazard can exist. Remove the series of screws around the perimeter of the panel.
2. Locate and disconnect the terminal lead wires from the element. Color coding may differ between manufacturers, so make sure you mark or label the wires as you remove them. If replacing both elements, do so one at a time to avoid confusion.
3. Open the oven door and remove (if possible). Refer to your owner's manual to see if there are instructions on how to remove the oven door. Some have spring-loaded locking hinges, while others just lift out. If you cannot remove the oven door, use care not to lean on the door or put too much weight on it. This can cause damage to the door hinges or cause the hinge springs to come loose.
4. Remove the oven racks, and remove the oven pan (if required - some elements are fully exposed, some have pan covers). There are usually two screws either in the back or front of the oven holding the pan in place.
5. The element will be mounted directly to the back of the oven wall, and/or to the bottom/top of the oven wall. Remove the mounting screws and remove old element from oven.
6. Install new element by carefully feeding the terminal leads through the oven wall first. Reinsert all mounting screws.
7. From the back of the range, reconnect the terminal wires.
8. Plug range in, turn oven/boiler on, and perform a visual test of the heating element to ensure it is working properly. Turn oven/broiler off and allow sufficient time to cool. If the oven has only been on for a minute or so, the cool down period will be brief. NOTE: Stand clear of any exposed wiring with rear panel removed.
9. UNPLUG range once again and re-install rear panel ensuring the terminal wires are NOT touching the panel.
10. Reinstall the oven pan and racks. Reinstall door if necessary.
NOTES: Prices vary between models and manufacturers, but most elements are in the $20-$40 range. There is a difference between the BROIL and BAKE elements in that they are usually different wattage ratings and are shaped differently. They should not be considered interchangeable.

For replacement parts - head on over to or and enter in your full model number for a full parts listing.
I recommend both sites because ...

FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.

If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.

Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

The terminal block is always at the rear of the oven.
There should be a removeable cover, which will expose the terminal block.
It may be screwed on, or a lift up plastic cover, but it will be there.

Unplug your power cord from the socket outlet.
remove the back cover where the power cord connection is housed. visually check the connection, expose wire harness might touches the cover somehow. or the cover was dent that causes the bare wire to touched the cover. correct the dent if any, or tighen loose wire.assemble back cover. Reset your circuit breaker to your Stove because the pop sound might trip off your breaker. That should solve the problem.

Electrolux EOB5600 electrical fault?

goto home depot,lowes and get some ceramic wire nuts and heat tape and electrical tape.cut the wires back on both sides of the terminal block.bypass the t-block and connect the wires with the wire nuts wrap the heat tape then electrical tape on each one.if you have access to a amp meter take readings to make sure the amp draw isnt too high.i would think the wires just burned up from either a loose connection or the heat of the oven.this should solve your problem.
