SERVICE MANUAL

Product Code No.	437 540 00

See the Service Manual of EM-F3400SW (SM-860304) except the items described in this Service Manual.

CAUTION

WARNING TO SERVICE TECHNICIANS

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

(d)Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the owner.

(e)A microwave leakage check to verify compliance with the Federal performance standard should be performed on each oven prior to release to the owner.

REFERENCE NO. SS-860313

CAUTION

For microwave energy emission

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

Measurement of energy emission

Measurement must be made with the microwave oven operating at its maximum output and containing a load of 275±15 milliliters of tap water initially at 20o±5o celsius (68 ±9oF) placed within the cavity at the center.

NOTE : The water container must be a 600 milliliter beaker and made of an electrically none conductive material such as glass or plastic.

The cook tray must be in place when measuring emission.

A properly operating door and seal assembly will normally register emission on greater than 4mW/cm2 to allow for measurement uncertainty with the cooking shelf or tray in place.

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

Follow the instructions supplied with a detector being used and performed an R.F. emission test around the door front and edges and all edges and vent of the outer case. The cabinet (wrapper) must be in place and the oven fully assembled.

When performing emission survey, with the meter on FAST RESPONSE the movement of a detector probe shall not exceed one (1) inch per second.

In the area emitting the highest reading, switch the meter to SLOW RESPONSE, and take a reading for minimum of three (3) seconds. We recommended the pattern outline shown below when the door surface is surveyed.

NOTE : Periodically check to be sure that the probe tip is not worn or dirty.

The following U.S. standard applies to microwave ovens : 21 CFR 1030.10, Performance Standard for Microwave Ovens.

It requires that the power density of the microwave radiation emitted by a microwave oven shall not exceed five (5) milliwatts per square centimeter at any point 5 centimeter (about 2 inches) or more from the external surface of the oven.

All microwave ovens exceeding the emission level of 4mW/cm2 must be reported to Dept. of Service for microwave ovens and the manufacturer 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.

*CDRH : Center for Device and Radiological Health.

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

Set cooking time to two (2) minutes. (“2 00” appears in display)

Touch “START” key and operate oven for exactly two (2) minutes.

Take out the two bowls at once.

Stir both water with thermometer and measure the water temperature rise respectively.

Get temperature rise by calculation the difference (water temperature after cooking minus initial temperature) in each bowl.

Then calculate average value(t) of both temperature rises in degrees centigrade.

Then work out :

Power Output (watt) = 70 x ∆ t

2. POWER OUTPUT MEASUREMENT

NOTE

The Power Output specification 1050W on this model is measured with IEC measurement. The Power Output is measured with two (2) liters water is equivalent to 1050W in measurement with IEC, when measured with the following Power Output.

(A)1 . Fill two test bowls with each 1 liter water respectively.

2 . Use accurate thermometer and measure each water temperature respectively.

(B)Place the two bowls on glass turntable.

Where ∆ t is an Average Temperature Rise in degrees centigrade.

(F)Power Output shall be in the following range :

Average	Microwave
Temperature Rise	Power Output
Minimum
24.3oF (13.5oC)	945W
Maximum
31.1oF (17.3oC)	1211W

(G)Power Output will be influenced by line voltage of power supply. Consequently, correct Power Output must be measured within 120V AC ± 1 volt while unit is operating.
