The Service Manual for the Kenwood KR-V55R provided by owner-manuals.com was as described/advertised. The contents provided the necessary information to effect a diagnosis of the unit. The schematics above all else was instrumental in tracing the the signal flow from component to component.

This manual was the factory original. Excellent value and contained all the details I needed. Easy dowwnload provided the information when I needed it.

The manual is of better quality compared to other. I found it less expensive and therefore it it is the best buy cost vs quality.

I bought the service-manual of the sony ICB-1020(an old transmitter-receiver) at "www.Owners-Manual.com", I found the service-manual for a fairly cheap price(in comparison with other sellers). I filled in some questions, payed the order with Ideal, and within 24 hours I had my service manual. I was very happy:In no time I had my service-manual and everything, but literally everything was noted down in the manual; the electronic scheme, the parts list, etcetera.
A very practical, reference-document.

(4) As a reference to determine the causes of trouble, malfunction and phenomena are described below. Refer to the following when repairing. 1. Disconnection of defrost heater As off-cycle defrosting is performed, the defrosting time is extremely prolonged. Each time defrosting is started, the freezer temperature rises and a portion of ice and stored foods are melted. 2. Melted thermo. fuse or opened-circuit due to the defect of defrost thermostat. When the above mentioned trouble occurs in cooling operation, the timer motor does not run, defrosting will not take place, and consequently freezing is caused. In the above mentioned condition, when the timer shaft is turned by hand to defrost, the timer motor runs during the operation time. However, the motor stops from the time when the contact is changed, and freezing causes. NOTE: As the thermo. fuse assembly is intended to prevent dangers, do not use it under shorted condition even for a short period. 3. DEW PREVENTION The hot pipe, namely D.P.-condenser, is arranged around the flange part of cabinet and the C-partition plate, preventing dew from being generated on the cabinet. NOTE: D.P.-condenser pipe may be felt hot if touched by hand while the compressor is in operation. If you are asked about this, please explain that the hot pipe serve to prevent the dew generation.

Figure F-7 4. INSPECTION OF INITIAL STARTING (1) Inspection of cooling unit 1. Set the temperature control knob to "MAX" and check that the compressor starts to operate. 2. Depress the door switch to run the fan and check that cool air is blown out of the cold air outlet of the freezer and the refrigerator. 3. When the compressor does not work, check that the timer is not set to "defrost" position. 4 It takes about an hour and a half or two hours to put food in the refrigerator after starting operation. NOTE: After return the temperature control knob to "MED" position. When the refrigerator is operated initially after installed, the compressor may vibrate excessively for 1 to 2 min. However, vibration becomes normal if it is continuously operated. (2) Inspection of defrost device Operate the refrigerator for 20 to 30 min. and then check the defrost device in the following procedures : Allow 5 min. to restart the compressor since immediate starting after stopping will cause unsmooth operation. 1. Turn the timer shaft clockwise with a screw driver. At this time, make certains the timer clinks and the compressor stops. 2. After more than 5 min., turn the shaft further to operate. Make certain cooling operation is started again.
