SOURCE: Fujitsu wall mounted air conditioner leaks into the room

Make sure the unit is level, this is very important. Check for blocked drain tube, which runs from the bottom of the drain pan under the cold coil to the outside. Clear tube with a piece of coathanger wire, be gentle.

Is it a split system? I had the same problem with my split system and and it was because the condenser line was mounted wrong. The line was mounted so the water had to go uphill and it was causing the condensation to leak through the front of the unit.

SOURCE: Fujitsu air conditioner - too much humidity

This can happen if the unit is too small for the room. Going by the model number I sounds like a big unit. I would also try cleaning the filters. Also set the temperature higher.

I take the time to help and answer your question so please rate me
Thankyou
Mat

I am having trouble with rewiring the air handler transformer and thermostat wires


Here is standard wiring on a low voltage transformer:

"r" on transformer goes to "r" on thermostat (use red wire)
"w"on transformer goes to "w" on thermostat (use white wire) (this is heat)
"y" on transformer goes to "y" on thermostat (use yellow wire) (this is cooling)
"g" on transformer goes to "g" on thermostat (use green wire) (this is the fan)

"c" (if used) goes to "c" or thermostat
"o" (used only on a heat pump)(orange) (reversing valve)

note: on most thermostats if you have an rc and an rh, they both must be jumpered together and use them as "r" (red)

Can not figure out how to wire it so ac works i have only 4 wires coming out of wall blue red white and yellow


Here is a general wiring solution:

Red is hot on a 24 v system, Red goes to "r" on thermostat
White is heat, goes to "w" on the thermostat
Yellow is aircond and goes to "y" on thermostat
Blue is fan and goes to "g" on thermostat

* note: this is typical and could not be 100% sure without pictures of the unit

Hello, Can you help me please. We have a Fujitsu Air Conditioning / Heating System installed into the ceiling of our local club. The Company that installed it have gone out of business and unfortunateley,...


Paul, it sounds as if the jumper on the thermostat between r/c and r/h is not installed properly. Heres how you can check to see if it is the thermostat or another problem
First turn off power to the unit. second remove the thermostat cover to expose the wiring. There should be a red white green yellow wires inside. If you take the red white and green wires and twist them together then activate you unit by turning on the power. If you get heat at that time then you will need a new thermostat if not then there is a problem with wiring between the thermostat and the main indoor furnace/airhandler. I would try this first before anything else only because it is simple and will let you know if you have worse problems.

Hope this helped you some

I need wiring manual for goodman mini split.


outside unit L1 and L2 are load (input 240vac)
then you have control voltage, usually yellow and blue (24vac) this connects to some 18/2 thermostat wire which goes inside as white and red.

note: this unit may only need 24v control which is 2 wires from the inside unit and also 3 wires 2 hot 1 ground for line voltage.

STANDARD WIRING
on the inside unit you have green, white, blue and red control wires.

on your thermostat you have white, red, yellow and green

you run the wire from the outside unit to the inside unit. then run a 18/4 wire to the thermostat if wired and join the following wires.

inside unit thermostat outside unit
green------------------------green
white-------------------------white
red----------------------------red
blue-------------------------------------------------------blue
yellow--------------------yellow

A duo therm thermostat (p/n 3105058) was removed because it would not operate the air conditioner/heater in a firan fireside camper. it was knocked loose from the wall damaging it.the thermostat is for use...


a. Remove the cover of the thermostat.
b. Connect the RED wire from the air conditioner
to the “RC” terminal on the thermostat.
c. Connect the “YELLOW” wire from the air conditioner
to the “Y” terminal on the thermostat.
d. Connect the “BLUE” wire from the air conditioner
to the “H” terminal on the thermostat.
e. Connect the “ORANGE” wire from the air conditioner
to the “G” terminal on the thermostat.
f. Push the thermostat wires into hole in wall and
fill excess hole with insulation.
g. Mount thermostat base to the wall with screws
provided.
h. Check all thermostat wires on base to ensure
they are completely clear of the bimetal coil of
the thermostat. Adjust if necessary.
i. Replace thermostat cover.
If nothing operates on the air conditioner, remove the
return air grille assembly and verify the red, orange, yellow
and blue wires are properly connected (red-to-red,
orange-to-orange, etc.).
Next, disconnect the red wires and check for 12 volt
DC between the red wire from roof section and the orange
or blue wire from roof section. If no voltage received,
refer to Section F2. If voltage is received, the
problem lies with the thermostat or thermostat wires.
Next, disconnect all 4 wires (red, orange, yellow and
blue) from the thermostat. With the thermostat set on
COOL mode, FAN mode set on AUTO and HIGH, and
temperature selector set lower than the room temperature. Check for continuity between terminal RC (red wire)
and terminal G (orange wire); and RC (red wire) and
terminal H (blue wire). If continuity is achieved on each,
proceed with the next step.
Set fan switch to LOW. Continuity should NOT be present
between terminal RC and Terminal H, but present between
the other terminals (Y & G) and terminal RC.
If all of the previous checks are good, the thermostat is
good, do not replace it. If any one of the previous checks
are not correct, replace the thermostat.

Manual Thermostat replcaement with Programmable Digital unit.


Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
R- red
AUX-white
Y- yellow
B- O/B
C- black
G- green
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
170-7
190-1
200-0
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters
