    Checking an oscillating fan motor

    I have an oscillating fan that quit working after getting knocked over one too many times (at least that's how it looks).

    The first test was to check the off/low/medium/high switch. It appears that there is continuity through that; touched the switch contacts only.

    Next, I replaced the capacitor with an exact duplicate. No success. The cap is a CBB61 two wire 3uF 250V foot mount.

    What is a good capacitor tester?

    I tried the shaft. It turns smoothly but I lubricated it anyway. Likewise the oscillating feature.

    The fan is an older SMC brand, Chinese made unit. Oscillating fans are going for $35 to $50 at Walmart and I am wanting to learn how to fix, even if fixing is more expensive than throwing away and replacing.

    I can send photos.

    Also what is a good, non-locking, crimper stripper tool (brand and model number)?

    I just got a crimper, but it is a crimper only and it is a locking type (it ratchets till the maximum force is applied, then releases).

    One of the wires wouldn't take that and the tool kept crimping through the wire. I am using bullet male and female 22 ga connectors.

    Thanks for you help.

    you really need to test to see if power is getting to the motor .

      You have no power going to the motor? Yep… straight shot, high resolution pix are a good idea to upload here using the attachment function.

        if cap failed, you can turn the motor by manual start.
        in this case, I think either power is not getting to motor or internally disconnected winding.

        first check if power is getting into motor.
        there is a thermal fuse in some motors. it is placed touched with winding. if it failed (this usually happen if motor stall for long time)

          Thanks for the recommendation. I plan to do that in the next few days.

            Nescafe Aeroccino, still fails with new Motor (red flashes only once)
            by juergenb
            Hi,

            i am asking for some Help.
            I have one of these Nescafe Aeroccino (Milk Frother) things with a bad motor.
            The Motor didn“t start anymore and internet is full of users just swapping the motor for a Mabuchi RF-500TB-12560.
            So i got a few of these from Banggood.

            I swapped the motor and now i have a new fault condition.

            In a working Frother you would press the start button, it will light red and work for a few minutes.
            If you press longer it will light blue and just mixup the milk.

            With the new Motor it just starts...

            charnwood w821 mini wood lathe motor problem
            by sbt123
            hi there,im having a look at repairing a wood lathe for my dad,(charnwood w821)the problem is when turning up the variable speed control,the motor starts to stop and start by itself,if i continue to turn up the speed it will trip the mcb in the consumer unit,there is also a slight smell of burning from the speed controll box.,Another strange symptom is the lathe can be unplugged from the mains after switching it off and the motor will spin a couple of times by itself,so far ive put a new speed controll potentiometer on and new motor brushes,ive also tested the motor windings and everything looks...

            Motor run capacitor physical size vs voltage rating & measurements?
            by Per Hansson
            (TL;DR skip the first paragraph)
            I encountered my first dead motor run capacitor at a customer this week.
            For some fields I guess it is a very common occurrence but the usual way for industrial machines here is to use 3-phase motors.
            (Unless a servo motor makes more sense that is).
            But for some reason this 3-phase machine uses a 1-phase motor for its liquid coolant pump.
            The pump would run but sometimes trip the 10A breaker.
            I monitored it starting and stopping for over an hour until it finally stopped in a specific spot between its windings:
            Then it could...

            Help identify this motor
            by mikey5791
            Hi all forum members,
            Found this unknown motor discarded in a junk yard and took home for learning experience. By the look of it, I suspect it is taken out from a type of air blower probably running on ac power. I used digital multimeter on ohm/resistance scale and it doesn't read anything on those 2 black wires. So, this motor is not shorted and should be good to run.

            Correct me if i am wrong on the initial test.
            Can anyone kindly advice on how to test run this motor based on visible external two black wires. Fyi, i don't see any marking on the motor body nor smell anything...

            Reebok one GT40s treadmill lift motor runs at switch on
            by G0RIT
            Good evening I am working on a Reebok oneGT40s treadmill. It had a flashing display which the replacement of D3 rectified. However the lift motor now runs when the mains is turned on and does not stop. If I then select start so the tread motor runs and disconnect the up lead to the lift motor it stops. If I then reconnect the lead the lift motor works as it should with the controls. It will continue to work correctly until the mains is turned off and on again, or the safety device is removed and replaced. It then runs again and only by disconnecting and reconnecting the up lead will it operate...
