I want a simple meter to check start and run motor capacitors. Will this unit let me know if the capacitor is good, blown, or whether I need a new cap?

This type instrument will only tell you the capacitance of the part. It will not tell you if it has insulation leakage. If it is shorted it would likely not be able to measure a capacitance, so that would be another indication that a capacitor is defective. Testing for insulation leakage is not easy to do without a more expensive capacitor checking instrument designed to measure that parameter. Power factor is another parameter that may be important to electric motor start/run capacitors and again requires a more sophisticated instrument to measure.

I've not used mine much, but the readings in capacitance mach the value of known good capacitors. I use a simple volt/ohm meter to check open or shorted capacitors. I can see lower than marked values on very old capacitors.

This unit will give you a reading of the amount of capacitance of the capacitor(cap) that you are testing. So, If your cap is good it will read close to what it is marked on the side of it, if it is blown it will read no capacitance which will require you to solder a new capacitor into the circuit. I hope this helps!

This is exactly what I bought it for, it tests for cap. value and will tell if blown or shorted. (value will change) It does not test ESR but does the job fine for me. Not real heavily built so keep it in the box and protected and it should last a long time.

First of all the is three different ways you need to test start and run capacitors. 1) is its capacitance and that is what this meter will do, 2) you need to check internal resistance and we use a ESR meter for that, 3) the next thing is voltage rating test , and leakage. and you need a real device to put load on it, Air conditioner and Compressors need good run and start caps, they are expensive do to there voltage and heat rating, if you are doing this for a job, you need a Capacitor tester and a ESR Meter. If just for one or two jobs Capacitor tester, and after they item has been running for 10 minutes, take a temperature reading of the cap, if it is getting warm, then it has internal resistance. Use safety when dealing with capacitors and always discharge them before testing. this is a item you need professional training on, for me I deal with them every day so I know what to look for. On a bad Start cap you will get a lug type of a start or hard start when bad or not in circuit. With a bad run cap you will get excessive amperage and over heat windings. So use a amp gauge also when testing the device.

I have no experience with motor capacitors.Physically they look big and this meter is for relatively small stuff, however, it might work.You should check to see if the size of the motor capacitors are with the range of the meter.On the other hand, if you put an ohm meter on a low range across a large capacitor it will show 0 ohms if it is shorted, OL, if it is open or over a few seconds go from low resistance to high resistance.Good luck

I have a UTIGAO, same model no. and it works really well, I used to work in a electronic repair shop and have tested this meter. You probably should discharge those capacitors before testing them, it might damage your meter. you can use a 2,000 ohm resistor and put it across the capacitor to discharge it.

I am not sure - suggest while you have it open to see if the capacitors are bulging - if they are, then I would replace them. You will also be able to confirm whether the specific capacitors in this kit are the exact ones you need.

It works great in my Sears whole house attic fan circa 1986. Don't know if it has a capacitor or not.

Nhaps this device is only for test Capacitance from a Capacitor, is not for test motors, please sorry my english..

You have a dual run capacitor the 80 is for the compressor and the 5 is for the condenser fan motor if the capacitor is still good you can use it also for the new motor but you need someone who knows how to test it and wire it don't try it yourself .

As previously stated, as long as the mounting points match, you should be good to go. I had to widen one of the mounting holes as this motor was slightly off, but that was it. When I bought mine, I also got a new start capacitor which I highly recommend. This one (http://www.amazon.com/gp/product/B004019SWG/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc;=1) worked perfectly.The wires controlling the rotational direction of the fan use quick connects so they are easy to swap if you need to change direction. I connected mine on the outside of the fan guard so I didn't have to disassemble my A/C unit to switch the direction.

Hello,This is a great analog meter which is perfect for testing all different types of diodes but not a great tool for testing capacitors. I would highly recommend a ESR meter for testing Capacitors. Hope this helps.

make sure the old capacitor has the same number of wires the new one has and the wires are the same colors it could have a different part number than the old one mine works great.

While I'm not familiar with the failure modes of a capacitor, it measures the capacitance and equivalent series resistance (ESR) for any voltage level capacitor. I've replaced capacitors in spite of it's reading within factory specifications because I was concerned that the ESR 70 unit wasn't operating at the higher voltage level. The capacitor was not the problem and I should have trusted the unit.

I did receive the capacitor with my motor but didn't use it. I checked the box that I kept my old motor in (keeping it for a temp backup) and I found the cap in a sealed box within.

Possibly. If you see what capacitors are bad then you can check what's included to see if it has the capacitors you need.

Not sure I understand what your saying. What do you mean by a "cap. starter motor"? But, you need to go by the amps on the motor. Make sure the motor is below the highest capacity for the controller.

If this is a new install, then I'd check that the input voltage setting matches the power being supplied to the motor.

If the capacitor on your fan looks like this one (2 wires on one side, 3 wires on the other side), it probably will fix your fan. When I first noticed my fan wasn't working correctly, one of the three speeds (I don't remember which) didn't work. Eventually another didn't work. Also, there was a very distinct odor. Replaced the original capacitor with this one & it's been working perfectly ever since.

Not sure. You will want to make sure the capacitors are rated the same for the brand you own. I believe it will work with other brands. You will want to check on line and google the brand you own to determine what the fix may be and the needed parts. You may find on U tube the process to fix.

Yes Deborah you can check fuses with the Multimeter. Most important is to make sure the power to the dryer is off before you start. If the power is on to the dryer you could be KILLED. Once you have the power off, remove the fuse. Then set the Multimmeter to Ohms. Touch the Black and Red probes to the fuse. If the Ohms shows Zero the fuse is good. If the meter does not move the fuse is blown or Tripped and it must be replaced or reset.I hope this helps. KarlKarl J Aspgren answered on May 13, 2014

I would be checking with Westinghouse, since it looks like capacitor could be bad from their website FAQ.Just surprising the capacitor would go bad on first day use.On speed #2 and 3 it rotates very slowly ,May be 3 rotations per 3 secs.
