HI, My Kenwood KEN CJ AL28 shorts out all downstairs plugs when i plug it in. It was fine then one day i was in the kitchen and the circuit breaker tripped. found out it was the microwave and it wasn't even in use. It tripps the circuit no matter which plug socket in the house I use. any ideas?

You probably loaded the turntable too much. There is a small compartment on the bottom. YOu have to open this to access the motor. Replace the motor.

the oven is short I suggest checking the capacitors and the power supply lines

Hi heshamyg, I want to help you with your problem, but I need more information from you.
Since I could not find the electrical specs for your particular model in the user's guide, please locate the information tag (plate or decal) and tell me what the wattage and amperage ratings are.
Page 5 of your user's manual recommends that your microwave should be used on a 15 or 20 amp circuit And that a "separate circuit servicing only this appliance be provided."
I don't know if this appliance is a new install to your kitchen appliance array, or if this unit has been around and in use for awhile without any problems.
Either way, the electrical circuit is being overloaded; short circuited; or because of a ground fault.

An overloaded circuit is one primary reason for a breaker to trip. It occurs when a circuit has more connected electrical load than it is supposed to have. When more current runs through the circuit than the circuit was intended to take, the circuit breaker is designed to "break the circuit." It does so to prevent overheating of the wire in the circuit, which can cause a fire.

• The most probable reason the breaker tripped is that you simply have too much plugged into one outlet or multiple outlets connected to one circuit.
• Move lamps, heaters, irons, hair dryers and other heavy power consuming devices to a different circuit not being heavily used; or
• Turn off some of the devices on the circuit to reduce the load.
• Loose connections are another possible but less common cause. With power off, check outlets for a loose wire and the electrical service panel hot wire connected to the circuit breaker to see if it has become loose. Re-tighten the connections if necessary.
• If these suggestions do not solve the problem you may have a more serious problem such as a Short Circuit or Ground Fault

The Short Circuit is a more serious reason for a breaker to trip. A short is caused when the hot wire (black) touches another hot wire or touches a neutral wire (white). It can also be caused if there is a break in a wire in the circuit. Shorts are a bit more difficult to diagnose because they can be caused by the wiring in your home or in something you have plugged into an outlet.

• Confirm that the power is off at the outlet into which your device is plugged.
• Inspect your power cords for damage or a melted appearance.
• Check your outlets and plugs for the smell of burning- or look to see if there is any visible brown or black discoloration.
• Check the insulation on the wires to make sure that they are not cracked; and that bare (uninsulated) black and white wires aren't touching together.
• If you do not find the problem, repeat the process for all the outlets in the circuit.
• Check for a Ground Fault condition.

A Ground Fault Condition is defined as: An unintentional, electrically conducting connection between an ungrounded conductor of an electrical circuit and the normally non-current-carrying conductors, metallic enclosures, metallic raceways, metallic equipment or earth.
In simpler terms, a ground fault condition exists when the hot wire (black) touches the ground wire (bare copper) or the side of a metal outlet box (because the metal box is connected to the ground wire). The ground fault is a type of short circuit.

The fix is the same as a short circuit except check that the hot wire (black ) is not touching the side of the metal outlet box or the ground wire.

If the problem is internal to the microwave oven, have it serviced by a properly trained service technician since one could expose themselves to dangerous levels of microwave energy.

Please keep me posted. Thank-you.

There is a panel under the microwave, held on by one or more screws. Remove it and you will see the synchronous motor inside. There should be a plug to disconnect the wires. Remove the motor and fit a new one. Ensure that the microwave is disconnected from the wall outlet before attempting any work on it.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARRAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Hi and welcome to FixYa, I am Kelly.
POWER OFF / UN-plugged
To gain acces to the motor the outer chassis must be removed. 4 side scews and 6 rear screas.. then life the rear of the outer cabinet 10 degrees and slide it aft to unlock the front tabs. Then remove the cover. Before you do anything; take a good screwdriver held by the handle and ground the HV capacitor 3 times across the 2 terminals to prevent a horrible shock.

The turntable motor will accept input (0utlet) power when disconnected and a test cord connected to the turntable motor PN TYJ5807A. Some of these are 24 Volt motors... make sure you look on the motor to determine the voltage. You can test the motor for resitance on R x 1,000 scale. I should read resistance to the 2 terminals only and NOT to the case. If it reads from either terminal to the case the motor has failed. The windings in these motors are MUCH thinner than human hair. http://www.buyspares.co.uk/search.pl?query=TYJ508A7

Take a good look at the motor drive post and make sure it matches yours. I could not find an exact parts break down for the CJ/AL28 but most turn table motors are common in a brand.

Thanks for choosing FixYa.

cheaper to buy a new one

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

You should be able to find parts here. If not, someone here should be able to direct you.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Two possible causes.

First (and most likely) the circuit is being overloaded. This kitchen circuit may be shared with another appliance (like the refrigerator) which is drawing enough power when both are running to trip the breaker. A Typical kitchen circuit is 20 amp with #12 wiring. So an 1800 watt microwave might draw 13 or 14 amps while a fridge compressor kicking in can surpass 7 amps before it levels off. If this is an older home the kitchen may have a 15 amp circuit with #14 wiring. If the circuit is a 20 amp you will have to split the appliances onto separate circuits. (Under code a kitchen must have a minimum of 2 separate appliance circuits). If it is a 15 amp you might be able to split them as well or may be looking up upgrading the breaker and the wiring from 15amp #14 to 20 amp #12 (but you could still have the same problem).

The other possibility is a short or loose connection. If splitting appliances onto their own circuits doesn't fix this you would probably want an electrician to come in and check for other underlying causes which could represent a fire hazard.

Hope this helps.

you should try a local wal-mart or even radio shack as these bulbs are somewhat common in many small appliances. Also, you may check at a local appliance repair shop.
