Sounds like the capicator is bad Also backtrack from the contactor for 24-volt power all the way back to the unit. or go to the thermostat, remove the cover and jump the red wire(power) to y=cool!

F6 error code on Frigidaire split unit ac, model FSC12CM6J/FSE12CM6J. Solution says to check fuse? Where is this located?


It seems like the indoor fan is not running. Quite a few split systems have a fuse on the indoor board. It will require stripping off the outer cover of the indoor unit and removal of the electronic box cover. The indoor board is in there. The fuse may be replaceable or it may be a type that is soldered on which makes it virtually non replaceable. ( A new indoor board will be required) Make sure all power is turned off or disconnected before you do anything. Another possibility is the fan motor start capacitor has failed. Try this first before stripping the unit. When the unit is turned on and the outdoor unit has started, give the indoor fan barrel a flick with your finger to start it spinning, if it keeps spinning and the error doesn't appear, it would indicate that the fan motor start capacitor has failed. The capacitors on indoor units are normally small black square boxes with 2 terminals on it. These capacitors are mounted inside or close to where the indoor electronic box is. Again, make sure all power is disconnected or turned off at the meter box before you do any disassembly.

Hooked up new 4 wire fan 2 condensor with a new 2 cap fan runs fine but no compresor?installed as was told with nothing runnng 2 the new cap but the brown wires but compresor isnt kicking on


The compressor could be bad there is two ways to tell with an ohm meter check each lead off the compressor and to ground for continunity or a megometer . You can always try a hard start kit. It is a super capicator that multiplies starting voltage. Have you checked all connections? There might be a low\ high Pressure switch in the referigent lines if that is bad it won't allow the unit to start. Also is it a heat pump or straight a/c the heat pumps have circut control boards in the unit that control everything

We replaced the compacitor, when you turn the control on inside the outside unit clicks and starts to hum, you can hear the new comp running. The fan will not kick on. All of the wires are connected and...


You have to replace the capacitor whenever you replace a compressor. You may have a bad fan motor as well usually when capacitors go bad the motor isnt far behind. This unit will have a dual capacitor for the fan and the compressor and yes one side can go bad and the other side be good. Replace the capacitor and let me know

Contact points on compreessor motor are sticking closed and unit (compressor) does not kick on. No breakers are kicked, when I cycle them the contacts keep locking closed and compressor remains off.


Contacts are bad need new contactor. This happens often, Check out very carefully to see why contacts are going bad. May need new capacitor.
If you have voltmeter check the compressor side of the contactor to see if you have voltage. Rus

Condesor fan stops working


is it one of those Smart motors? it is there save on the electric bill. you actually only need a motor that run fast enough to remove the heat from the coils,one speed you just do not get power saving.

Condenser fan running backwards on heat pump


I am having the same problem, sometimes it runs in the wrong direction, blowing the air down. Sometimes something gets tripped and I need to turn the thermostat to off and wait a bit then restart it. If I am lucky it will run int the correct direction and also will warm the house. Sometimes it send nothing but cold air to the house's forced air.

Outdoor fan motor is not running fast enough?


Check to make sure that you have the correct voltage going to the motor. It sounds like you lost one of your legs of power which would give you 110v instead of 220v. Or it could be in the pc board.

Blower fan runs continually with the thermostat removed or installed. This is a older carrier combined unit with a furnace. Control board installed is a HH84AA 011. Replaced the board with a new board and...


your sensor to the fan is stuck in the closed position. This sensor kicks the fan on when a certain temp is reached in the heat chamber. It opens after cool down and apparently is stuck closed.
