A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.
;
Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.
;
Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.

some of the writing is a bit blur but the part in the schmatic was great and i have fixed the machine thanks

Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

OPERATION SEQUENCE
Note: The On/Off time ratio does not exactly correspond to the percentage of microwave power, because approx. 3 seconds are needed for heating up the magnetron filament. 2. The relay RY4 and RY3 are energized and the main supply voltage is applied to the convection heating element and the grill heating element. 3. The oven will continue to turned the convection heating element on and off to maintain the temperature for the programmed cooking time. And simultaneously the grill heating elements will be operated at 10% power output. CONVECTION COOKING (by 40�C _ 230�C) Programme the cooking time by touching TIME keys. And then programme the desired convection temperature of 40�C 230�C by touching CONVECTION key. When the START key is touched, the following operations occur: 1. The relays RY1, RY6 and RY7 are energized, the oven lamp, turntable motor, fan motor and convection motor are turned on. 2. The relay RY4 is energized and the main supply voltage is applied to the convection heating element. 3. The oven will continue to turned the convection heating element on and off to maintain the temperature for the programmed cooking time.
GRILL COOKING CONDITION
TOP GRILL (Figure O-3a) In this condition the food is cooked by the grill heating element . Programme the desired cooking time by touching the TIME keys and touch the GRILL key once. When the START key is touched, the following operations occur: 1. The numbers on the digital read-out start the count down to zero. 2. The oven lamp, cooling fan motor and turntable motor are energized. 3. The relay RY3 is energized and the main supply voltage is applied to the top grill heating elements. 4. Now, the food is cooked by the top grill heating elements. NOTE: The convection cooking condition will be curried out simultaneously until the temperature of the oven cavity rise to 220�C.
DUAL COOKING CONDITION CONVECTION COOKING CONDITION (Figure O-4)
PRE-HEATING (by 40�C - 130�C) Programme the desired convection temperature of 40�C - 130�C by touching CONVECTION key. When the START key is touched, the following operations occur: 1. The relays RY1, RY6 and RY7 are energized, the oven lamp, turntable motor, fan motor and convection motor are turned on. 2. The relay RY4 is energized and the main supply voltage is applied to the convection heating element. 3. After the temperature of oven cavity rises to the selected one, the oven will continue to turned the convection heating element on and off to maintain the temperature for 30 minutes. PRE-HEATING (by 160�C _ 250�C) Programme the desired convection temperature of 160�C - 250�C by touching CONVECTION key. When the START key is touched, the following operations occur: 1. The relays RY1, RY6 and RY7 are energized, the oven lamp, turntable motor, fan motor and convection motor are turned on. 2. The relay RY4 and RY3 are is energized and the main supply voltage is applied to the convection heating element and the grill heating elements. 3. After the temperature of oven cavity rises to the selected one, the oven will continue to turned the convection heating element on and off to maintain the temperature for 30 minutes. And simultaneously the grill heating element will be operated at 10% power output. CONVECTION COOKING (by 250�C) Programme the cooking time by touching TIME keys. And then programme the convection temperature of 250�C by touching CONVECTION key. When the START key is touched, the following operations occur: 1. The relays RY1, RY6 and RY7 are energized, the oven lamp, turntable motor, fan motor and convection motor are turned on.
R-953/963M - 5
MICROWAVE AND CONVECTION (Figure O-5a) Programme the desired cooking time by touching the TIME keys. Touch the DUAL CONV./GRILL key once. Select the microwave power level by touching the MICROWAVE POWER LEVEL key. And select the convection temperature by touching the CONVECTION key. NOTE: The 100% microwave power level can not be selected. When the START key is touched, the following operations occur: 1. The numbers on the digital read-out start the count down to zero. 2. The oven lamp, fan motor, turntable motor and convection motor are energized. 3. The relay RY4 will be energized and the main supply voltage is applied to the convection heating element. 4. The relay RY2 is energized and the microwave energy is generated by magnetron. 5. Now, the food is cooked by microwave and convection energy simultaneously. MICROWAVE AND TOP GRILL (Figure O-5b) Programme the desired cooking time by touching the TIME keys. Touch the DUAL CONV./GRILL key twice. Select the microwave power level by touching the MICROWAVE POWER LEVEL key. When the START key is touched, the following operations occur: 1. The numbers on the digital read-out start the count down to zero. 2. The oven lamp, fan motor and turntable motor are energized. 3. The relay RY3 is energized and the main supply voltage is applied to the grill heating elements. 4. The relay RY2 is energized and the microwave energy is generated by magnetron. 5. Now, the food is cooked by microwave and grill simultaneously.
