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.

Whatis ideal r22 gas pressure required in 1 ton split ac of BlueStar.


Doesn't matter how big the unit is, pressures remain the same. On a satisfied temperature, approximately 75 degrees, r22 should be around 65 psi. The hotter the house, the higher the pressure. Head pressure varies on outdoor temperature. 90 degrees outdoor temp, approximately 200 to 225 psi on high side.

H3 Error in bluestar... is it compressor problem?


Typically no... Yogesh,

It is a compressor overload...
(look outside... Is a dump truck parked on it...??
(perhaps the winter cover is still on top??)).

Over-charge of refrigerant, crushed plumbing,
clogged DRYER, defective expansion valve..
condenser cooling fan is slow (or no go).

If you were to disclose the recent history... A blind,
remote, poorly informed FIXER might be able to point
you in the right direction. ... or you could just continue
throwing "is it?" games... and get answers that are just
as valuable... (not much).

One possibility is the compressor... Many opportunities..!
An experienced refrigeration person could look directly at the system...

The only thing you keep repeating is
H3, Bluestar & compressor...

You could try helping... Pretty please?

No spark and no power: Bluestar 36


Is there power at the outlet? I know that it is probably very hard to get to behind the heavy Bluestar, but it looks like you may have to pull the stove away from the wall and make sure it is still plugged into a working outlet. All of those stove functions are fairly separate, so to have all of them go out, you probably have a power supply problem. There may even be a break somewhere between the plug and where it splits off into the fan/light/ignitor parts.
