REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

KELVINATOR – ELECTROLUX SPLIT AC ERROR CODES – CHECKING PROCEDURE

Kelvinator – Electrolux Split AC error codes – checking procedure

H5, Indoor unit.
Yellow LED, Outdoor flashing 10 times. (IPM Protection)
Disconnect the supply power to the unit by means of the isolation switch.  Remove the Blue-U, Yellow-V & Red-W flag terminals from the compressor, then measure the resistance value of each winding from these points.
Note: The resistance value should be the same across any terminal combination. 
If all resistance checks are okay, replace the outdoor PCB assembly.

F3 Indoor unit.
Red LED, Outdoor flashing 6 times. (Outdoor Ambient Sensor)
F4, Indoor unit.
Red LED, Outdoor flashing 5 times. (Outdoor Coil Sensor)
F5, Indoor unit.
Red LED, Outdoor flashing 7 times. (Outdoor Compressor Discharge Sensor)
 Check the Condenser Coil, Outdoor Ambient & Compressor Discharge triple point sensor plug for correct connection. 
 Check the continuity of each individual sensor, if anyone of the sensors is open circuit; replace the complete triple connector plug assembly.
Note: If all the above checks relating to the sensors & wiring have been completed, yet the error code still exists, replace the main outdoor PCB.
Condenser Coil, Outdoor Ambient & Compressor Discharge sensor connector plug on main outdoor PCB.
F1, Indoor unit. (Room Temp Sensor Failure)
F2, Indoor unit. (Tube Temp Sensor Failure)
Check the Indoor Ambient & Indoor Tube sensors for correct connection.
 Check the continuity of the relevant sensor, if the sensor is open circuit, change it.
Note: If all the above checks relating to the sensors & wiring have been completed, yet the error code still exists, replace the indoor PCB.
H6, Indoor unit. (Indoor Fan Stall)
 Check to see if the indoor barrel type fan blade is turning freely.
 Check the evaporator fan motor for correct operation. If the fan motor is not operating check if both three pin AC-Motor connector plugs are anchored correctly to the indoor PCB.
 Check for AC voltage between the Brown & Red wires located on the upper AC-Motor connector plug:
The above AC voltage readings can fluctuate within a range of 10 volts. 
Remove the three pin upper AC-Motor connector plug & check the resistance value from the following points:  • Brown & White (332 ohms)
Note: If the above AC voltage checks are not available, replace the main indoor PCB assembly.
Note: If the above resistance values are not available, replace the indoor fan motor.
Indoor fan motor connection plug points.
L3, Indoor unit.
Red LED, Outdoor flashing 14 times. (Outdoor DC Fan Motor Malfunction)
 Check the condenser fan for correct operation. If the fan motor is not operating check the three pin DC-Motor connector plug for correct termination to the outdoor PCB.
 With the unit set in heating or cooling mode (depending on ambient conditions) Check for DC voltage from the points illustrated below, located on the main outdoor PCB.
• Red & Yellow wires: < 13 Volts DC.
• Red & White wires: < 13 Volts DC.
H3, Indoor unit.
Yellow LED, Outdoor flashing 8 times. (Compressor Overload Protection)
Check the following points: • Refrigerant charge.
• Restrictions within the capillary tube.
• Poor air flow across the indoor & outdoor coils.
• Correct operation of the four-way reversing valve.
Check the compressor Over Temperature connector plug located on the outdoor PCB for correct termination & continuity to the over temperature protector.
Check the over temperature protector located next to the three compressor terminals.
Note: This over temperature protector is “normally closed”.
