Why is water is coming into the room through the
Most probable cause is a clogged drain line or a drain that is not properly pitched. Ensure the unit is level and that the drain line is properly pitched and clear. Some units are equipped with a small condensate pump. The unit will leak water if the pump is not working properly.
No heat
Hi,
Look on the back of the panel or in the book to see what the five flashes stand for...
Porbably a tripped or bad high limit switch...

My fan inside run only 5second the ciruits board
Shut the power off to the unit, spin the blower wheel to see if it spins freely. If it doesn't spin freely, (there appears to be a little drag when you spin it),the bearings are bad, if it does spin freely, then try moving the motor shaft from side to side if there’s any play in the shaft side to side then the bearings are worn and motor needs replaced. Then, check the capacitor, if it’s bulging even slightly, the capacitor is bad and needs replaced. Most of the time people replace the capacitor if motor seems ok. If capacitor is ok, turn power on to see if the motor is getting the proper voltage, if it is and not trying to run, then the windings are probably open, the motor's bad and needs replaced.
Is the split ac will function if the distanc is
generally speaking yes, the linesets may have to be sized larger, and depending on location and oil trap may need to be installed to insure oil return to the compressor. There should be line sizing charts in the installation instructions.
Fan motor replaced and motor came with new
there is a series of low voltage terminals in the area where your blower is R,W,Y,G,and C R-is 24v power W-is for heat Y-is for cool G-is for fan C- is for common make sure that these wires are not touching eachother and that the wires are also the same inside the thermostat
Compressor fan moter not working
It is likely the capacitor for the fan motor. Unless you are comfortable working with 240v this is an issue for a qualified service tech. If you are comfortable with it, replacing the capacitor is fairly simple, you can probably obtain one from most electrical supply houses. It would be the smaller of the two capacitors contained within the exterior unit, the larger one is for the compressor motor.
FAN MOTOR WIRE PUT ON WRONG SIDE OF COMP CONTRACTOR _OOps
Check for power at the disconnect and contactor on most residential units you should have 240 volts ac between the terminals
and 120 volts to "ground" or "earth". Some disconnects have fuses in them.
If you have circuit breakers I see little reason for
fuses
other than to create a service call. I usually replace them with copper
tubing.
Most contactors will allow you to push them in manually
(DANGER HIGH VOLTAGE). If the fan runs and the compressor does not then
you have an electrical problem with the other component. There are cases
where a grounded compressor or bad fan
motor will cause the fan motor to run slow even though the contactor
is not pulled in. A bad run capacitor
will cause the compressor not to run and the same for the fan motor. Some
units have a dual run capacitor that takes care of both and if it fails
(it has an internal fuse) the motors will just hum (drawing high current)
but not run. The compressor will have an internal overload that will disconnect
the compressor after a few seconds of not starting. It will remake as soon
as it cools, this condition can be mistaken as a bad compressor. Some compressor
will require a "hard start
kit" to solve starting problems and if it doesn't have one I recommend
one as a preventative measure.
Use a clamp on ammeter to verify which parts are drawing current. If there is no current flow
through the capacitors then that is a clue they may be bad.
DO NOT let your system run if the either
fan motor (inside or out) is not working you will destroy your compressor,
the same goes if your unit is
icing up or short of charge
you will burn up your compressor
motor.
No control
voltage: Most residential units use 24 volts ac to pull in the contactor.
The power for this usually comes from a step down transformer in the furnace
or indoor unit through the thermostat.
Some outdoor equipment will have its own transformer, but this is rare
for residential.
If the indoor blower fan wont also work then the problem is NOT the contactor in the outdoor unit but
a problem with the thermostat or the wiring
to it either at the subbase or the furnace. Before replacing your thermostat
you should isolate the cause of the problem or it will persist and drive
you nuts. Look for wires touching or cut too long.
A contactor or relay is an electrical
device that takes a control signal usually 12 volts DC, 24, 120, 208-230
volts ac and creates a magnetic field to pull in a set of contacts that
controls another device that may or may not get its electrical power from
the same circuit. Note: 99% of most control circuits are 24 volts AC.
The contactor has steel contacts that
are plated with silver. When the silver wears away you have just plain
steel and the steel will weld itself together. Sometimes if you whack the
contactor with a screw driver you may free it for a while but the problem
will re occur. This problem is especially a problem when a piece of equipment
has not been run for a period of time.
It is normal for the contactor to wear
out over time like brake pads on a car. If the contactor shows any signs
of wear it should be replaced as a preventative measure or as part of maintenance.
If you suspect a stuck contactor a
100% accurate test is to turn off the power to the indoor section which
removes control voltage to the outdoor section and it (outdoor section)
keeps running. Do not keep messing with it, your contactor it is
bad and you will destroy your compressor if you let it run!!!
Some heat pump systems use two run capacitors (total of
3 if you include the fan) instead of a crankcase heater for the compressor
(GE, Rheem/Ruud and others). It is possible for the contactor to fail where
the compressor or the fan will run but not the other. When replacing a
contactor on a system like this be extremely careful to get the wiring
correct or the compressor may be damaged. so kindly check ur compressor....
both brown and blue wires as mentioned before cary 24volts
If the fan and the compressor dont run then you must have a break in a
wire or a bad contactor. It also could be the run capacitor. Either
way, leaving the power on could harm the compressor. It may have
already. Check to see if the compressor and fan share a run capacitor. It shud be a dual capacitor that boosts the compressor and the fan. It shud read open between the common and each of the other two terminals.
good luck.....
if u found me of any help kindly rate my service.....
Carrier A/C system (P250H) smells like urine
Since the smell could only come from the inside, and you say your drain pan, and condensate line are clear, I would think that the indoor coil may be dirty, and the water isn't flowing from the coil, but dripping into the duct, and becoming stagnate. There are many possiblities, you may want to get a flashlight and check all of your duct openings for things such as moisture, and unfortunately dead animals. Sometimes mice, squirrels, rats, bats, etc. find ways into the duct, and either die, or urinate in the duct and so on. I hope you find it. Good luck.
