Fan makes a clicking noise, usually after being on for awhile. Is not blades, as it makes noise when the blades are off. Have lubed everything that can be seen (including bearings) with silicone. Still "clicks". Fan came with 5th wheel rig, so there isn't a warranty. Fixable?
Bearings are "sealed" and can't be lubricated but can be replaced. $8- 10 bucks at bearing store or $2 -3 bucks on ebay. get standardized number stamped in side of bearing and search ebay. I got 2 for my fan at $1.69 each plus shipping for a total of $6.28 delivered in 3 days. See www.usabearingsandbelts.com

I get this complaint a few times a month , what I usually find is that the circulation fan has a build up of fuzzy lint on the blades and it throws the fan out of balance (hence the noise) a soak in a warm water/soap solution usually takes care of it , disassembly is required for this , I usually charge two hours labor for this
The clicking is generally caused by a flat roller bearing. If the sound seems to be from the fan clutch you can grab the fan blades and see if the bearing is worn by rocking the blade by pulling it towards you and rockng it away from you Another way to see if its bad is to use a solid pole something like a broom handle. Place one end of the handle on the accessory that runs off the serpentine belt such as the alternator and place your ear on the other end of the handle. As the engine runs you can hear a bearing making noise revolving as it move. If a bearing is bad the noise will be much louder and have a heavy grinding noise
It is normal for the fan to stay on after the engine is off. The clicking is not. Once the negine is cooled down and the fan is not running. check the fan by spinning it and try to locate the clicking noise. Make sure the fan doesn't wobble. If it does then the bearings are going out, replace the fan. The clicking could be something lodged in the shroud, clicking against the fan blade. Like a stick.
Check that all the blades are aligned when the fan spins. If one blade is higher or lower than the others it throws the fan out of balance and makes a clicking noise. Also check that the pitch on all the blades is the same, this has the same effect. The blades can usually be bent just a bit to correct any misalignment.
Hi, couple main reasons to get loud clicking in a computer. First is the hard drive, so if you can turn the system off and disconnect the power and the information cable from the hard drive, yes your computer will not boot all the way back into windows but that is ok since you just want it running for awhile to see if the clicking stops. Next thing would definitely be the fans, any fan in the system, the blade part of the fans can get loose sometimes and start to hit the sides as it spins around, you need to be sure about which part it is that is causing it, it can come from the power supply fan, the case fan, the video card fan, the cpu fan, and you might have more than one case fan, test by disconnecting one at a time just make sure to disconnect the device too so you do not over heat anything. Once you identify which fan just replace it, if its something like power supply or video card, unfortunately you might want to look into either warrantying the part or buying a new one.
does the fan wobble at high speed? if so change the order of the blades to try & balance it.i.e. number the blades on a piece of tape on each--switch blade # 1 & #3-better or worse? 2&5;better or worse?etc. untill it runs smoothest.
first you have to remove all shelves in the freezer,then remove all screws in the interior rear panel. In some cases you'll have to remove a couple of shelf tabe located on the side wall. Once tha panel is removed,the fan will be in plain sight. The blade is usually aboue 4-5 inches in diameter and is attached to a small motor with 2 wires and a green grounding wire. Note: you might want to check why it's making noise. Is there ice built up around the blades?Are you getting too much moisture entering the box thru faulty door gaskets?
Yes, the fan blade is hitting something inside.Usually by opening the microwave, you can slide or reposition the plastic fan blade on the shaft.Probably this happened in shipping to the store where you bought it.CAUTON:make sure the unit is unplugged before you attempt this.Other option is return for replacement.
