The ceiling fan ticks at the edge of the bed. The first move is a new set of blades, because wobble is treated as warped wood. The screws in the hub were a quarter-turn shy. The first fix bought four paddles. The hub never took them square.
When a fan that used to run true starts to rock, and the canopy still sits still, that rock is usually a screw in a blade iron, not a pack of paddles that left the shop bent. A bent rod, a canopy that walks, a motor that hums and heats, and a blade that is actually cracked are not hub screws. A slower speed is not a repair. It is a way to sleep under the same fault. I changed a set of paddles in June. The wobble came back on the second night. One iron still had a screw I could turn with two fingers.

The screw in the iron
A ceiling fan is a motor, a rod or a hugger body, and three or four blades on irons. The irons take screws into the hub. Leave one screw shy and that blade tracks a different circle. At speed the fan draws an oval. From the bed the wood looks guilty. The wood is often still straight. The iron is not tight.
Why buy paddles first? Because you can hold wood. You cannot hold a thread you have not looked at. A sleeve of blades feels like a finished job. A quarter-turn on a hidden screw does not.
Power off at the wall. Let the blades stop. Stand on a step that does not rock. Try each screw on each iron. If one turns, that was the oval. Buy wood only after the irons have failed to hold a true circle.
When new blades are the job
Not every rock is a hub screw. Wood fails. A blade that took a crack from a moving box will keep the oval after every screw is tight. Water-swollen paddles will too. Then the sleeve is the job.
A canopy that has walked on its mounting screws will rock the whole body even when every iron is tight. You see the cover shift. That is the box in the ceiling. A rod bent from a knock will throw the motor off axis. New blades will follow the bend.
A motor that hums, smells, or runs hot is not a screw job. Power off. Leave it. Worn bearings can wobble and then seize. Do not treat heat and smell as a balance-kit problem.
Should every wobble wait for a new fan? No. Motors die. A fan that rocks and heats is not a paddle story. The usual case is the rock that arrives in a fan that used to run true, with a canopy that still sits still.
What the new paddles did
August the fan was quiet at one. At three it was drawing a circle against the curtain. Same paddles. One iron had lost a screw onto the wardrobe. The wood looked guilty. The thread was empty. That split is why a new set feels reasonable. One night was calm. The next was not. A dead motor does not pick a single iron.
I kept the old paddles in the spare room for a week. The new set wobbled the same. The iron that had given up its screw was still the iron that gave up. That is one house. One house is still better evidence than a third set of wood bought to avoid looking up.
Dust on one blade will throw a light fan. I wiped one paddle because it looked worse. The oval changed shape. It did not leave. Uneven dust is a small version of an uneven iron. Wipe all of them, same pass, before you buy wood.
Before you go to the shop
Turn the fan off at the wall. If there is an isolator, use it. Wait until the blades are still. Use a step that does not rock. Do not stand on the bed edge. Try every screw on every iron. Snug is not stripped. If a screw spins without tightening, the thread in the hub is gone. A new paddle will not grow a thread. Stop there: replace the iron or the fan, not the sleeve.
If the screws are home and a small oval remains, a clip-and-weight kit can help. Put the clip on the blade that rides highest at the tip. Pick a crack or a paint line on the ceiling and watch one tip pass it. The tip that comes nearest the line is the high one. Move the clip a few centimetres and run one speed. If the oval jumps to another blade, go back to the irons before you buy a second kit. The kit is a trial after the screws, not a diagnosis instead of them.
A wobble that shows only on the fastest speed is still an iron until you have tried the screws. Fast speed makes a small miss visible. Slow speed can hide it. Checking one speed and calling the fan fine is how the tick comes back at three.
Hugger fans, the ones with almost no rod, wobble less from a bent rod and more from a canopy that is not flat on the box. If the body walks when you push it with the power off, stop talking about paddles. The box or the canopy is the job.
Three-blade fans show a miss sooner than five-blade fans. There is less wood to hide an iron that is out. That is not a reason to buy five paddles for a three-arm hub. The arms have to match the hub you already have. I stood in the shop holding a five-blade box and put it back when I counted the irons on the ceiling. The count has to match.
A light kit under the body adds weight on the axis. It does not tighten an iron. People blame the glass shade for a new wobble after they change a bulb. Did anyone touch the irons while the shade was off? If the answer is no, the shade is not the oval. If someone leaned on a paddle to reach the bulb, check that iron first. The bulb job and the wobble job get mixed because they happen on the same ladder.
Seasonal wood moves a little. A paddle that was true in a wet month can dry and twist a few millimetres. That is a real warp. The test is still the screws. If every screw is home and one tip still rides high after a dry week, then wood is the job. If a screw turns, wood was never the first job.
What a quiet night does not prove
A quiet night does not prove the next season will leave the irons alone. Vibration works screws back. It does not prove that a house with a loose ceiling box only needs tighter irons. A canopy that walks is not an iron story. A humming motor will not be saved by a fourth paddle.
Tight irons will not last the life of the house. Seasons dry the wood a little. What you can stop is treating every oval as a reason to buy paddles. Another set is for wood that has failed. A new fan is for a motor or a box that has failed. The screws in the hub are for the night only one iron was singing.
I left the receipt for the new blades on the fridge. I used the old ones after I found the empty hole. The receipt is still there. The fan has been quiet. Look at the irons before you look at a sleeve.
