A Warning and Safety Instructions

1 General InformationService and repair work should only be carried out by a suitably qualifiedelectrician (with specialist training, knowledge and experience, and recent relatedwork experience) in accordance with all appropriate local and national safetyregulations.

Servicing, modification, testing and maintenance of electrical appliances shouldonly be carried out in accordance with all appropriate legal requirements, accidentprevention regulations and valid standards.

All regulations of the appropriate utility supply companies and standards relatingto safety (not limited to electrical safety) are to be complied with.

Before starting any service work, the machine must be disconnected from power.

Even with the machine switched off, voltage may be applied to somecomponents.

A general visual check should always be carried out.

There may be a risk of injury due to sharp edges. Protective gloves should beworn and the edge protection, mat. no. 05057680, should be used.

Descriptive Technical DocumentationDTD no. 24-6160 A-1


2 High Voltagesx

Danger!

Normally when the microwave oven is switched off, the built-in dischargeresistors in the high-voltage capacitors discharge the capacitors.

For safety reasons, it is important to ensure that the high-voltagecapacitors are discharged by always short-circuiting them before startingany maintenance or repair work.

When the microwave oven is connected to power, the following componentshave potentially lethal voltage applied to them:

• High-voltage transformer (T1)

• High-voltage capacitor (A4)

• Diode (V1)

• Magnetron (G2)

Descriptive Technical DocumentationA-2 DTD no. 24-6160


3 Discharging the High-Voltage Capacitor

Note

Although the high-voltage capacitor contains an internal bleed resistor toautomatically discharge the capacitor, the following procedure must beperformed! Do not rely on a functioning resistor!

Unplug the appliance.

Remove the cover. See Cover Removal, 001 4.5.

Using an insulated-handled screwdriver, touch the blade from one terminal on thecapacitor to the other terminal on the capacitor. This may result in a ratherstartling “pop!”

Using the same insulated-handled screwdriver, touch the blade from eachterminal on the capacitor to the frame (ground) of the appliance.



4 Microwave EnergyMicrowave energy is created by the magnetron or another microwave generator.x

Danger!

The body must not be subjected to any microwave energy under anycircumstances as this could result in serious internal injuries.

The following points must always be complied with:

• The magnetron or other microwave generator must be connected correctly.

• All input and output connections, waveguides, flanges and seals must besealed correctly.

• A microwave oven must never be operated without a microwave load.

• Never look into an open waveguide or antenna when the microwave oven ison.

In order to ensure that no microwave energy can escape after any repairwork has been completed, the microwave oven must be thoroughlychecked for microwave leaks in accordance with all applicable local andnational regulations. (In Germany: VDE regulation 0700 and CEEregulation 335 apply.)

Checks should be carried out using a suitable microwave leak detector (mat. no.05595470). Particular care should be taken around the door and the casingedges.

The maximum permissible value is 5mW/cm2 (32.3mW per square inch),measured at a distance of 5cm (2 inches) from the oven with a water load of275cm3 ±15cm3 (0.073 gallons ± 0.004 gallons).

Descriptive Technical DocumentationA-4 DTD no. 24-6160


5 Touch Current Measurement

Note

On machines with a ground connection, touch current leakage measurementsshould be carried out on all accessible conductive parts that are not connectedto ground.

Warning!

Touch current measurement should only be carried out after the groundconnection of the machine under test has been checked and found to besatisfactory! Dangerous voltages may exist on defective machines as well as onaccessible conductive parts that are not connected to ground!

Note

Touch current measurement should be carried out on the following accessibleconductive parts:

• Stainless-steel door.

001 Overview

2 Function

2.1 Fan Run-On

With all cooking processes lasting longer than 3 minutes, the cooling fan isswitched on for 2 minutes at the end of cooking regardless of whether the doorhas been opened or not. The fan, however, only operates when the door isclosed. If the door is opened during this time, the fan run-on time is reducedaccordingly.

2.2 Automatic Keep-Warm Function

If, at the end of a cooking process with at least 450W microwave power, the dooris not opened, then after 2 minutes the keep-warm function is activated andcontinues for a maximum of 15 minutes with microwave power of 80W. Thisfunction cannot be selected separately. The display shows H:H.

The automatic keep-warm function can be deactivated in the programming mode;see Programming Mode, 001 4.2.

2.3 Safety Feature with Door Display

If the door has not been opened within 20 minutes before starting a cookingprocess, the appliance cannot be started and door is displayed. This reduces therisk that the appliance can be started with nothing in the oven.

The door warning can be deactivated in the programming mode; seeProgramming Mode, 001 4.2.

Descriptive Technical DocumentationDTD no. 24-6160 001-1

Remedy

A Advise the customer that the gourmet plate should not be used on the rackbut should be placed directly on the turntable.

Cause

The gourmet plate has less than 1” gap to the cavity walls.



Remedy

A Advise the customer that the gourmet plate should be placed in position sothat the gap to the cavity walls is at least 1”. If the gourmet plate is too large, itmust not be used.

3.5 Time Not Displayed and Appliance Is Switched Off

Symptom

If the appliance is not used for 10 minutes, the time display is switched off. Theappliance is also switched off and must be switched on again before it can beused.
