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.

1996 amana top freezer refrigerator not cooling


Check power to and from thermostat and to compressor relay. If compressor powered but not running, compressor fault. If compressor running but no heat in condenser, short of gas. If compressor running and heat only in first rungs of condenser, compressor poor pumper and needs replacing.

I have a Rheem heat pump/air handler; it draws 2.9amps with only the fan running, 13amps when the heat pump is running and 38amps with the heat strips on. My question is why the unit draws that many amps...


Sounds like it must be about a 2.5- 3 ton system. The 13amps has to be the compressor draw -normal. and 38 on the strips- normal. 2.9 fan -normal.

You may want to check your wiring to see where the outside unit gets its power. Theres nothing inside that can draw 13 amps. That almost has to be the compressor power wire.

Will not switch to cool mode. heat and fan work fine


hi,
regarding on switch mode theres a common line between heating and cooling although fan is always connect on them.,also with the thermostat,the sequence on this when you switch to cooling and your connection is on heater,the contactor will shift to compressor source,so if there is no cooling, the contactor supplying the compressor is not functioning when you switch on cool mode.try to tighten screw on compressor relay maybe only loose.on control panel,or check continuity of compressor if the compressor still good,check also the freon charge using clamp ammeter,this should be done by ac technician.have a nice day
rate me up,thank's

AC Compressor


Does not sound right to me.My guess after doing what every he was doing he probably installed a start capacitor or repaired a burnt wrie, got the compressor running and charged for a lot of guess work. Just guessing.
