Brand: Sanyo

Model: EM-V758

Category: Microwaves

Type: Supplement Of Service Manual

Sanyo EM-V758 is an advanced microwave oven with a variety of features that make cooking easier and more convenient. One of the notable features is its precise power output, which can be adjusted to suit different cooking needs. With a maximum power output of 900W, it can quickly heat and cook food items. Additionally, the microwave features a built-in turntable that ensures even cooking by rotating the food while it cooks, resulting in evenly heated dishes.

See the service manual of EM-V860 (SM-640126)

except the items described in this service manual.

Foreword

,:.. ...

Read this manual carefully, especially precaution on microwave energy, and follow the procedure strictly. Careless ser- -

vicing and testing may expose yourself to the microwave energy leakage.

PRECAUTIONS

PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCES-

SIVE MICROWAVE ENERGY

(a)

(b)

(c)

(d)

Do not operate or allow the oven to be operated with the door open.

Make the following safety checks on all ovens to be serviced before activating the magnetron or other micro-

wave source, and make repairs as necessary:

(1) Interlock operation, (2) proper door closing, (3) seal and sealing surfaces (arcing, wear, and other dam-

age), (4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.

Before turning on microwave power for any service test or inspection within the microwave generating com-

partments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity,

and connections.

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.

2. POWER OUTPUT MEASUREMENT

NOTE

The power output specification 900W on this model is

“rfmeasured with IEC measurement. The power output

measured with two (2) liters water is equivalent to 900W

in measurement with IEC, when measured with the

following power outwt.

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

respectively.

2. Use accurate temperature 0 C and measure each

water temperature respectively.

(B) Place the two bowls on glass turntable.

appears in display)

2. Touch START key and o~erate oven for exactlv two

(2) minutes.

(D) 1. Take out the two bowls at once.

2. Stir both water with thermometer ana measure the

water temperature rise respectively.

(E) :. Get temperature rise by calculation the difference

(water temperature after cooking minus initial

temperature) in each bowl.

2. Then calculate average value(t) of both temperature .~~’.

.....

rises in degrees centigrade.

.. .

3. Then work out;

Power Output (watt) = 70 x t

(F) Power output shall be in the following range

Power Output

(G) Power Output will be influenced by line voltage of

power supply. Consequently, correct power output

must be measured within 240V AC* 2 volt while unit is

operating.

CHECKOUT PROCEDURE

Measure the

voltage: Between test points

TP-1, TP-2 or TP-3 and ground between

TP-4, and TP-5. (See control circuit board

on page 9 )

NOTE

– Proceed with the check of the step-down

transformer, to see if any one

of the

measured

values is different from the

specified values.

Measure the resistance between terminals,

of FPC connector after removing it from

SIO1. (Figure 2).

NOTE -

—

When reconnecting the FPC connector,

make sure the holes on the connector are

propedy inserted

in hooks of the plastic

fastener

in S101.
