Unfortunately they do not make replacement parts for this kind of product as they are cheap to replace. You can make it work with some simple steps. The only problem with a broken blade is balance. Take off any pieces that are loose or going to fall off on when spinning. Now get some duct tape and a few coins. Tape the coins to the opposite side of the blade that is missing parts to even out the weight. Now turn it on and listen for a rattle. If will take a few cycles to get the weight correct but once you have it balanced it will work almost as good and new. Please keep your face and body clean when turning it on for the first time in case parts go flying. Good luck. Thanks
If this started after the new fan was installed,then the housing the fan sits in is not secure.Or the fan blade is out of balance which means you will need a new fan blade. Check that all nuts and bolts are tight.If there is a belt be sure it is not worn or missing pieces.
You have something in or on the fan blade. If you live where there are dirt dobbers, they will build their nest right on the outside blade. You will need to take the cover off to inspect. Also, as for the inside blower wheel, it could have something sucked up into it throwing off balance.
It's a quite complicated procedure but i'll try to describe as best i can.
Below the air outlet there should be a couple of screws. They may have small tabs over them (purely for aesthetics!).
If you lift up the filter cover, remove the filters and remove filter cover (trying carefully not to break it... darn plastic!) there may be some screws above the air outlet.
Remove the fascia cover starting from the bottom. Pull it out over the louvre in the air outlet. It will be clipped at the top near the back. These can be difficult to undo. Once that's done, remove the cover.
For the next bit, make sure that the power is turned off to the unit. (power cord unplugged, isolator turned off or c/b off depending on power source)
Undo the screws on the power box.
Undo the screws on the drain tray and off the left side of the evaporator coil. (Big finned section of pipework). Make sure you support the evaporator coil as it's only connected with copper pipes which bend/kink fairly easily.
You'll need to pull the coil out a little (not too far) and take off the left hand rubber 'bearing' as such from the indoor fan barrell.
On the right hand side of the unit you'll find the fan motor (which is held in by the power box) There should be a grub screw that holds the fan barrell onto the shaft of the motor. This is usually undone with an allan key but have seen them with phillips head screws also. This grub screw might be in a few different places. It might simply be on the right end of the fan barrell or sometimes the righthand column of blades is missing a blade and the grub screw is accessed by putting allan key/screwdriver up missing portion. You only need to loosen the grub screw, not remove it.
Once loosened, the fan barrel can be pulled off the motor shaft and removed.
Once off, you can inspect it for obstructions or broken blades etc. To reassemble is just the reverse of these instructions.
Just a few things to note:
1. Be careful of the evaporator coil not to kink (or break!) the copper pipes or your a/c won't work properly.
2. The drain tray may have water in it if the a/c has been operating recently.
3. Make sure the power is off before pulling off the power box.
This can be a very difficult task and I would recommend having an assistant to help with holding stuff.
Check the radiator for dirt, and check if the radiator fan is functioning. Do you notice any wetness or ice build up on the outside copper pipes. If so, suggest calling a refrig. tech. to add gas. The gas used is R22 on most aircons.
- Check if the fan blade is not broken or unbalance fan blade. - Check if bolts are tight enough. - Check if the fan motor rubber grommet is complete and balance. - Check also compressor rubber grommet is complete. - Re tight all screws and bolts on the condenser unit. - Check the condenser installation if balance.
