REPAIRING AND NOT THROWING AWAY

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.

ERROR CODES and CIRCUIT DIAGRAM - HAIER AIR CONDITIONER

HAIER AU242FHBIA  AU482FIBIA  AU48NFIBJA Air conditioner Error Blinking codes Circuit Diagram
Indoor failure code
A. Wired control type indoor unit:  The dip switch of wired controller is 1 and 3 at ON, 2 and 4 at OFF.
Failure code Failure description
E0 Float switch abnormal
E1 Outdoor unit failure
E2 Abnormal mode operation
E3 Liquid pipe temperature sensor failure
E4 Gas pipe temperature sensor failure
E5 Repeated indoor unit number (E5 flashes for a while and then turn to E9)
E7 Communication abnormal with EEV box
E8 Communication abnormal between wired controller and indoor PCB
E9 Communication abnormal between indoor and outdoor
EB (pre-set, not available) Water temperature sensor abnormal.
Infrared control type indoor unit:
TIMER lamp flash times Failure description
Once Liquid pipe temperature sensor failure
Twice Gas pipe temperature sensor failure
3 times Ambient temperature sensor failure
4 times Communication abnormal between indoor and outdoor
5 times Communication abnormal with EEV box
10 times Indoor motor abnormal
11 times Float switch or pump motor abnormal
12 times Repeated indoor unit number
13 times Indoor over heat
Note: if indoor RUN lamp flashes, that shows outdoor abnormal, so no matter how many times it flashes, you should check outdoor indicator flash times and the relative failure code.
