Good quality service manual.It has helped me to fix my FV1800,particularly for replacing the dial cord.The scheme is on A3 format and very readable.Thank.Olivier.

This manual is complete and very readable.It was a great help for my two ICF5800L.The first one had the dial cord broken,and without the service manual it is impossible to replace it.Thank.Olivier.

This is a top quality manual. You couldn't get better if you had the original and scanned it yourself. Best price on the net as well. Diagrams are clear and complete, text is sharp and easy to read. Granted you don't get the manual the second you click pay, but the few hours you have to wait for it to be available for download isn't a problem at all. This is a very reliable company.
Very VERY pleased with the product, and will buy others. Thanks!

In a word AWESOME.
I never expected the quality and abundant content that I got with this manual. Everything you'd ever want to know from a service perspective is found in this manual, along with... as a bonus, operating instructions on how to use the unit. WOW. Very impressed with the quality of the manual. You won't be disappointed if you're looking for the EVS900 service manual.

I thank Owen-Manuals.com for the wonderful service rendered to me, and this manual which I purchased helped me a lot in servicing my Denon System, which was lying in a dead state.
Thanks Owner-Manual.com

9 CAUTIONS TO BE OBSERVED WHEN TROUBLESHOOTING
Unlike many other appliances, the microwave oven is a high voltage, high current device. It is free from danger in ordinary use, though extreme care should be taken during repair. Caution Servicemen should remove their watches working close to or replacing the magnetron. whenever
9.1.
Check the grounding
Do not operate on a two wire extension cord. The microwave oven is designed to be grounded when used. It is imperative, therefore, to ensure the appliance is properly grounded before beginning repair work.
9.2.
Inverter warnings
Grounding of the inverter circuit board WARNING! DISCHARGE CAPACITORS THE HIGH VOLATGE
DANGER, HIGH VOLTAGE AND HIGH TEMPERATURE (HOT/LINE) OF THE INVERTER POWER SUPPLY (U) This high voltage inverter power supply handles very high voltage and current for the magnetron tube. Though it is free from danger in ordinary use, extreme care should be taken during repair. The aluminum heat sink is also energized with high voltage (HOT), so do not touch when the AC input terminals are energized. The power devices Collector is directly connected to the aluminum heat sink. The aluminum heat sink may be HOT due to heat energy, therefore, extreme care should be taken during servicing.
For about 30 seconds after the oven is turned off, an electric charge remains in the high voltage capacitors in the inverter power supply circuit board. When replacing or checking parts, remove the power plug from the outlet and short the inverter output terminal of the magnetron filament terminals to the chassis ground with an insulated handle screwdriver to discharge. Please be sure to touch the chassis ground side first and then short to the output terminals.
H.V. Inverter warning WARNING FOR GROUNDING INVERTER POWER SUPPLY (U)
Discharging the high voltage capacitors WARNING There is high voltage present with high current capabilities in the circuits of the primary and secondary windings, choke coil and heat sink of the inverter. It is extremely dangerous to work on or near these circuits with the oven energized. DO NOT measure the voltage in the high voltage circuit including the filament voltage of the magnetron. WARNING Never touch any circuit wiring with your hand or with an insulated tool during operation.
Check the high voltage inverter power supply circuit grounding. The high voltage inverter power supply circuit board must have a proper chassis ground, the inverter grounding bracket must be connected to the chassis. If the inverter board is not grounded it will expose the user to very high voltages and cause extreme DANGER! Be sure that the inverter circuit is properly grounded via the inverter earth bracket.
