Check your indoor air handler unit. If the coil is frozen, it is usually one of two problems. You are low on freon, or your filters are clogged and not allowing enough airflow over the coil.
The gurgling sound sounds like freon is flowing thru the system pipes. Is the larger of the 2 copper tubes running cold to the touch? Hi-Low module make also be the problem. It tells the inside fan when to turn off and on.
Sounds like you need a new contactor in the condenser. The low voltage is grounded. Remove the low voltage (likely 2 wires) at the condenser and wire nut the wires leading inside. With an insulated screwdriver manually push in the contactor and be sure both compressor and fan run. Then replace fuse and turn power on to air handler with a call for cooling. Obviously the outdoor unit won't run because you unhooked the low voltage but if fuse doesn't trip then it's likely the contactor. Good Luck
that is the fan on start-up and the high pitch is the power supply components heating up make shure that the main fan is working always it will be slow at low volume if it quits you run the risk of the power supply failing
Is the indoor unit operating? If no turn the fan from auto to on at thermostat. If the fan comes on, that is a sign that you have 24volts
present on thermostat side.
Turn AC unit off outside,turn the thermostat as low as it will go. Open the electrical panel to the outdoor unit. There is a contactor located in the unit, push the plastic bar in the middle of contactor. If it pushes
in, you have low voltage wiring problem from the outdoor unit to the
indoor unit.
If you are skilled or know somebody that is with electrical, turn the power back on to the outdoor unit take a non conductive object and
push the contactor in, the unit may start. If it doesnt start,check the
breaker for the ac unit to make sure it is not tripped.
If the breaker is not tripped and the condensor fan comes on and the
compressor does not come on and the breaker does not trip, then it
is very possible that you will need a new capacitor and while you are
at it put in a hard start kit.
This unit according to you, still should have 2 years left on the compressor warranty.
CHECK FREON LEVEL...IF GOOD CHECK FOR DISCONNECTED THERMOSTAT OR COMPRESSOR OR CONTACTOR WIRE AT OUTDOOR UNIT WITH POWER OFF. CHECK FOR A BLOWN CAPACITOR OR UNIT GROUNDED OR BURNT WIRE. BAD BREAKER OR SEE IF OUTDOOR FAN COMES ON AND COMPRESSOR KICKS IN ( MAKES WHIRRING NOISE ) .
INSIDE CHECK BOARD FOR BLOWED FUSE, GROUNDED WIRE, MAKE SURE SYSTEM IS GETTING 24 VOLTS, IF NOT CHECK THERMOSTAT WIRES OR TRANSFORMER ON INDOOR UNIT.. IF YOU SET THERMOSTAT TO OFF AND ON AND THE INDOOR FAN COMES ON..YOUR GETTING 24 VOLTS.NOW YOU NARROWED TO THE BOARD OR LOOSE WIRE, FUSE OR THERMOSTAT. IF YOU TURN YOUR UNIT ON COOL AND AUTO AND THE INDOOR AND OUTDOOR FANS COME ON AND THE COMPRESSOR KICKS IN BUT IS NOT COOLING...CHECK AND POSSIBLY ADD FREON... ALSO CHECK AND MAKE SURE INDOOR BREAKER IS ON.
Sounds like you lost the refrigerant charge. Low pressure switch will not let compressor run. Look for oil around the condenser tubes. If you find it, this is probably the leak source.
