BLOWN FUSE IF IT IS QUICK IT WOULD INDICATE A SHORT, IF IT IS SLOW COULD BE A BAD MOTOR STARTING TO DRAW HIGH AMPS.

Wat is H3 error in bluestar split Ac?


Hello Yogesh...

Unless you are familiar with the BASICS of REFRIGERATION...
"H3" ERROR CODE means it is "Out of ORDER"...

Broken: Needs repair.

By searching the internet "split A/C " It defines a
COMPRESSOR overload protection is trying to
SAVE your equipment FROM SELF DESTRUCTION.

See second detail sheet (below)

"COMPRESSER"
Is the heart of MOST modern refrigeration systems.
In a SPLIT system it is the outside unit with the FAN
that should be running when the COMPRESSER is
in action. Typically then compressed & COOLED
REFRIGERANT is then piped into a cooling element
EXACTLY LIKE MOST REFRIGERATORS where the
cooling takes place (expansion valve and evaporator).

Treated AIR (indoor) is then blown through the
evaporator... cooling the room and warming the
refrigerant (which continues to cycle back to the
outside unit where the compressing cycle
continues until the INSIDE temperature is
achieved... (thermostat on the wall)

"COMBINED"
pretty much means EVERYTHING but those combined refrigeration units seen WORLD-WIDE HANGING OUT OF WINDOWS... or on roof-tops with DUCTING for
"treated AIR" to be pumped where needed.

Similarly heat pumps simply have reversible valves...
which turn the coils around (functionally).

There too are split-system (inside/outside) & combined units.

I have a split-type aircon (brand: LG) with remote control.It has power and display when i put on batteries. but the aircon unit does not respond to the remote control. what do i do to fix this?...


Lift the front cover of the air con, on the right hand side there is a button or a hole which has a button inside which you can press which is for manual starting of the air con. If this works, then you will know the remote is faulty, if it still doesn't work, check that the isolator switch for the air con hasn't been turned off. There will be 9Or should be) a switch outside next to the air con outdoor unit to switch power on / off to the air con. If not, there should be switch inside the meter box at the front of the house. Make sure they are switched on.

My air con just suddenly stop blowing air and the timer button just starts blinking. every time i switch on the aircon it will auto shut down and the timer button lights up please help me to fix it.


Owner's manual? troubleshooting? Possible it's smart enough to know you have an air filter that needs changing or cleaning.
No manual? Try MFG web site, or email their customer service, or try manualslib.com

I have a Daikin Ducted Air con system which shuts itself off when-ever the temp is over 33 degrees celcius. An error code E5 comes up which means that either the Compressor is over heating or there is a...


E5 Outdoor activation of compressor over heatprotection or motor lock.
Dear friend! Replacing spares for defective will not solve problem. But, you must know why it happened?
In your unit,Condenser unit was completely dust blocked. First clean it. And also replace running capacitor. If recently replaced, ignore it. Check motor for bearings. It's mechanism locked due to bearing worn out or weaken capacitor. Ask repairman to check with amps meter for fan and also with compressor. And also loose wiring if any. Compare with unit specified amps.Hope problem would solve now.
