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.

air compressor on Heil air conditioner is humming but not kicking in


Capacitor Failure Symptoms are sometime harder to identify without the right tools and expertise. Capacitors can be found in several different sizes and shapes. There may be one or multiple capacitors included in your ac with regards to the design. While the most popular capacitors are the types found on circuit boards, the ones most associated with air conditioning will be the bigger capacitors that assist start and run your motors. There are several motors present in an conditioner and heater systems:
  1. Compressor Motor Run Capacitor: Here is the most popular capacitor that fails. Most of the time these are duel capacitors, which means that there are 2 capacitors built into one. A duel capacitor will have three terminals on the top where a single capacitor will simply have two terminals on top.
  2. Outside Fan Motor Run Capacitor: That is the smaller capacitor found with or part of the Compressor Motor Capacitor. It helps start and run the outside fan that blows air through the outside coils.
  3. Indoor Blower Motor Run Capacitor: Similar to the outdoor fan motor capacitor, it is a small, single (two terminals) capacitor that will help start and run the indoor blower motor.
  4. Start Capacitor: Some models include an auxiliary start capacitor that helps jump start the motors. Most are found on the compressor. These are less common.

You may need to get that checked out.

I have an older Goodman CKB 18-1


FOR QUESTION 1: They do run independantly. What will happen when your compressor is running but your outdoor fan does not, the pressures in the system will go really high and compressor will overload. That outdoor fan is used to disipate all the heat that is transferred from the inside to the outdoor unit.
FOR QUESTION 2: If you hear humming it can be 2 things. FIrst one is that that capacitor went bad. Dependiing if its a dual run capacitor(which helps both compressor and fan motor) or they both have individual capacitors. The second would be a bad fan motor. OPen your service panel outside to the AC. Find your capacitor for you fan motor. if there are 2 , locate the one that goes to your fan motor. Check it out(if its blown physically youll will notice it like really bubbled, like swollen) then change itout. Or you will have a dual run capacitor that runs both compressor and fan motor. It will have the terminals marked (Fan, Common, Herm) Bsically check your capacitor mfd(micro fared rating, it will say on the capacitor what its rated) Get a multi meter and put in the "MFD' selection. Before you check any capacitor you have to discharge the the voltage charge it has. Use an insulated handle screwdriver and just place the metel part across the capacitor leads. Basicall short them out. Then proceed with checks...hope this helps( remember to always pull the disconnect out from the box outside to cut power)

c6 error code on LG art cool


Try turning the power off at the fuse box, waiting 5 minutes turning the system back on and spray some water on the vents on the side of the outside condenser. If the fan isnt spining get a twig and spin it in an anti-clockwise direction after 1 or 2 spins it should start spinning on its own. continue to hose the vents with water for another 5 minutes. Its important to have the fan spinning as it extracts the heat from the condenser box.
