GENERAL

IMPORTANT SAFETY INFORMATION

ELECTROSTATIC DISCHARGE

(ESD) SENSITIVE ELECTRONIC

ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly

may appear to work well after repair is nished,

but failure may occur at a later date due to ESD stress.

IMPORTANT SAFETY

INSTRUCTIONS

Before touching any oven component or wiring, always unplug the oven from its power source and discharge the capacitor by using a 20,000 ohm discharge resistor or use an insulated plastic handle screwdriver to short across the capacitor terminals.

Check that the unit is grounded before troubleshooting. Discharge any static charge from your body by touching ground before handling any part of the circuitry on the control board. Electrostatic discharge may damage the control circuit.

Do not touch oven components or wiring during operation. Attach meter leads with alligator clips when making operational tests. For continued protection against radiation emission, replace only with these types of switches: Primary (Interlock) Switch: SZM-V16FA-63 or VP-533A-OF; Secondary (Interlock) Switch: SZM-V01-FA-32; Interlock (Monitor) Switch: SZM-VI6-FA-62 or VP-532A-OF; Oven Lamp Switch: SZM-V6-FA-31 or VP-331 AOD.

• Use an antistatic wrist strap. Connect the wrist strap to a green ground connection point or unpainted metal in the

appliance; or touch your nger repeatedly

to a green ground connection point or unpainted metal in the appliance.

• Before removing the part from its package, touch the antistatic bag to a green ground connection point or unpainted metal in the appliance.

• Avoid touching electronic parts or terminal contacts. Handle the electronic control assembly by the edges only.

• When repackaging the failed electronic control assembly in an antistatic bag, observe the above instructions.

It is neither necessary nor advisable to attempt measurement of high voltage.

Attaching the adaptor ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal and not insulated and the wall receptacle is grounded through the house wiring.

1-1

WARNING TO IN HOME SERVICE PROFESSIONALS

To avoid possible exposure to microwave radiation or energy, visually check the oven for damage to the door and door seal before operating any oven. Use a microwave survey meter to check the amount of leakage before servicing. In the event the R.F. Ieakage exceeds 4 mw/cm2 at 5 cm, appropriate repair must be made before continuing to service the unit. Check interlock function by operating the door latch. The oven cook cycle should cut off before the door can be opened.

The door and latching assembly contains the radio frequency energy within the oven. The door is protected by three safety interlock switches. Do not attempt to defeat them.

Under no circumstances should you try to operate the oven with the door open.

• Proper operation of microwave ovens requires that the magnetron be properly assembled to the waveguide and cavity. Never operate the magnetron unless it is properly installed.

• Be sure the “RF” seal is not damaged and is assembled around the magnetron dome properly when installing the magnetron.

• Routine service safety procedures should be exercised at all times.

• Untrained personnel should not attempt service without a thorough review of test procedures and safety information contained in this Job Aid.

Whirlpool microwave ovens have a monitoring system designed to ensure proper operation of the safety interlock systems.

The interlock monitor switch will immediately cause the oven fuse to blow if the door is opened and the primary door interlock switch and/or the secondary interlock switch contacts fail in a closed position.

CAUTION: Replace a blown fuse with a 20 ampere class H fuse only.

Test the upper and lower door interlock switches, cook relay and interlock monitor switch (middle switch) for proper operation as described in the component test procedures, before replacing the blown oven fuse.

Do not attempt to repair sticking contacts of any interlock switch, safety switch, or Cook (Latch) relay. The components must be replaced.

Any indication of sticking contacts during component tests requires replacement of that component to ensure reliability of the safety interlock system.

NOTE: If the fuse is blown, the monitor, primary, and secondary interlock switches must be replaced. Be sure they are properly connected.

1-2

PRECAUTIONS TO BE OBSERVED BEFORE AND

DURING SERVICING TO AVOID POSSIBLE EXPOSURE

TO EXCESSIVE MICROWAVE ENERGY

A. Do not operate or allow the oven to be

operated with the door open.

B. Make the following safety checks on all

ovens to be serviced before activating the magnetron or other microwave source, and make repairs as necessary:

1) Interlock operation

2) Proper door closing

3) Seal and sealing surfaces (arcing, wear, and other damage)

4) Damage to or loosening of hinges and latches

5) Evidence of dropping or abuse

C. Before turning on the microwave power

for any service test or inspection within the microwave generating components, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections.

D. Any defective or misadjusted components

in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced, or adjusted, using procedures described in this Job Aid, before the oven is released to the owner.

E. A microwave leakage check to verify compli-

ance with Federal Performance Standard should be performed on each oven prior to release to the owner.

F. Do not attempt to operate the oven if the

door glass is broken.

1-3

R.F. LEAKAGE TEST

EQUIPMENT

• Electromagnetic energy leakage monitor (NARDA 81 00B, HOLADAY H 1501 ).

• 275 ±15 ML glass beaker.

TEST

On every service call, checks for microwave energy emission must be made according to the following manner.

1. Remove the cooking rack from the oven

cavity, if the microwave oven is so equipped.

2. Place a 275 ±15 ML (9.3 oz.) glass of

water in the center of the oven bottom.

3. Select “HIGH” cook power, turn the microwave

oven on, and test for R.F. Ieakage at the following locations: a) Around the cabinet at the front. b) Around the door. c) Across the console panel. d) Horizontally across the door. e) Vertically across the door. f) Diagonally across the door. g) Across the air vents. h) Across the rear air vent. i) All lockseams. j) Weld at bottom. k) Bottom plate. I) Oven feet.

4. The scan speed is one inch per second.

When checking for R.F. Ieakage, use an approved R.F. measuring device to ensure less than 4 mw/cm2 emission at 5 cm distance with a maximum scan rate of 2.54 cm/second, in compliance with U.S. Government Department of Health, Education and Welfare 21CFR1030, performance Standard for Microwave Ovens. A properly operating door and seal assembly will normally register small emissions, but they must be no greater than 4 mw/cm2 to allow for measurement uncertainty.

NOTE: Enter leakage readings in BEFORE and AFTER spaces on the service document.

All microwave ovens exceeding the emission level of 4 mw/cm2 must be reported to Dept. of Service for microwave ovens immediately and the owner should be told not to use the microwave oven until it has been repaired completely.

If a microwave oven is found to operate with the door open, report to Dept. of Service, the manufacturer and CDRH* immediately. Also tell the owner not to use the oven.

The interlock monitor switch acts as the nal

safety switch protecting the customer from microwave radiation. If the interlock monitor switch operated to blow the fuse when the interlocks failed, you must replace all interlock switches with new ones, because the contacts of those interlock switches may be melted and welded together.

If safety interlock/monitor switch replacement, or adjustment, is required, you must reconnect the circuit, and perform a continuity check on the monitor circuit.

All repairs must be performed in such a manner that microwave energy emissions are minimal.

THEORY OF OPERATION

AIRFLOW PATHS

The microwave uses the exhaust blower motor to remove vapors from the cooking area below the unit, it also circulates air within the unit to assist cooking performance and cool the operating components.

cooling

This process is accomplished by using one side of the blower motor assembly to pull ambient air into the unit to cool the working components,

and the remaining side of the blower for exhausting steam and cooking odors.
