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 SPLIT AC - COMMUNICATION FAULT – ERROR CODE E6 – CHECKING PROCEDURE

Kelvinator split AC - Communication Fault – error code E6 – Checking procedure

Electrolux - Kelvinator split AC - Communication Fault – error code E6 – Checking procedure
E6, Indoor unit.
Green LED, Outdoor unit on.
Check for DC voltage at the following points:
• Turn the power off at the isolation switch then disconnect the Signal Wire off the indoor terminal block.
• With the Signal Wire disconnected, turn the unit back on and leave it in “standby mode”.
• With a multimeter, test the DC output from the signal wire connecting to the indoor unit & earth.
• If the meter reads a low stable voltage, the indoor PCB should be okay.
• Then by using the same method, test the output signal on the terminal block from the outdoor PCB & earth.
• If the meter reads a pulsing voltage in the low 50's, the outdoor PCB should be okay.
• If the meter reads 0 DC volts, this would indicate the PCB in question is faulty.
Note: If both indoor & outdoor PCB’s appear okay, continue to the following page.
Disconnect the main power supply to the indoor unit by means of the isolation switch. After approximately one minute, turn the power supply back on & attempt to operate the unit in “Auto” mode with a set temperature of two degrees above or below the ambient temperature.
If the Communication fault has not cleared:
Check for supply voltage at the following points.
• Between the Active -Out & Neutral points on the indoor PCB.
• Between the Active & Neutral points on the indoor terminal block.
• Between the Active & Neutral points on the outdoor terminal block.
• Between the Active & Neutral points on the outdoor PCB.
Note: If all the above checks relating to the supply voltage points have been completed, yet the error code still exists, continue.
Active - Out & Neutral supply voltage points on indoor PCB.
Active & Neutral points on outdoor terminal block.
Active & Neutral supply voltage points on indoor terminal block.
Active & Neutral supply voltage points on outdoor PCB.
Disconnect the supply power & check the continuity of the COM-U wire from the following points:
• COM-U terminal point on the indoor PCB.
• To the communication terminal points on the indoor terminal block.
• To the communication terminal points on the outdoor terminal block.
Note: When checking the continuity between the indoor terminal block & the outdoor terminal block, disconnect the COM-U & Active wires on the indoor terminal block, and then attach them together. This will create a circuit that can then be tested between the COM-U & Active terminal points on the outdoor terminal block.
Note: If all the above checks relating to the COM-U points have been completed, yet the error code still exists, continue.
Check the continuity of the reactor. If open circuit, change it.
If the reactor is okay, replace the outdoor PCB assembly.
