Worked on a capacitor-excited generator

Bought this for a friend's generator that suddenly stopped outputting a usable AC voltage. One of the wires connected to the capacitor had shorted out to the frame, the capacitor had no capacitance, and could not hold a charge so at least that was a problem. After dismantling much of the generator and a little research I found no other problems and determined that the capacitor provided power to magnetism the stator coils. Apparently the 50uF value was crucial to the output voltage. This replacement must have come fully charged (I didn't check) because when it was plugged in & the generator was started it was immediately able to power a corded drill. We were very happy that that was the problem rather than needing a new AC generator to bolt to the engine or a new generator/engine unit.

Where's my easy button?

My pentair whisperflow wfe-4 wouldn't kick on, it was getting current because it was hummig and super hot. I started researching and found the problem could be the run capacitor. So I took the hump cover off and took a picture of the label and started googling numbers. Took me a while to figure out what I needed. I found a similar replacement part on digi-key. It had all the same specs except the tolerance and was about the same size. Before I committed, I tried to figure out what would happen if I used a capcitor with a higher tolerance. I found a website that explained what ll the various numbers I found on the label meant. Not only did it explain the tolerance, but listed parts they sell. They had the exact part I needed, same size sme connectors same tolereance. I decided I would buy from them because their website did such a good job of explaining what I needed to know. But just to be sure to check on price, I came to Amazon and found the exact same part from the same seller and it was a nickle less! Anyway, long story short, the part worked perfectly, plugged it in, put the cover back on, flipped the switch and it cranked right up. Easy

Capacitor works great on pool pump motor and is sple to install

The capacitor works great! My pool pump motor stopped working and I found a video on YouTube that helped me identify it was the capacitor that was the problem. The motor would hum but not turn on its own. The motor turned easily when I used a screw driver to turn it's shaft and when I did this with the power on it gave the motor the jump start it needed to work. The capacitor I ordered from Amazon was less than half the cost of what it would be in a pool store. It was so simple to install on the motor I had my 12 year old son do it. Just be sure the circuit breaker is off.

Get your pool motor working fast and easy!!!

So happy with this product. We bought a house with a pool two years ago; in that time we have had the pump stop working at least six times. Every time I'd get a brief electrical hum and a click but the pump wouldn't "turn over". If this has happened to you and you have any experience changing anything at all electrical (seriously, even a light switch), do not call a repair company!! Buy this instead. On my sixth time this problem happened I decided to give it a try on my own... was able to get my pump started with literally five mins of work and just the cost of this capacitor (instead of the $150 my pool company charges for the fix)! Just watch a Youtube video and go for it! Delighted. Expert suggestion: you should buy two to have one on reserve... better than waiting a few days to fix your pump next time, as the life of capacitors is anywhere from 4-18 months max in my experience.

Solved my problem.

What can I say. It solved my problem, which was a stalled start: a classic sign of needing a new capacitor. (A stalled start is experienced when the motor emits a rather loud humming sound, but fails to turn over.) Just be sure to match the power requirements and the mfd rating of the capacitor you are replacing. Note there are capacitors rated for "starting" and "running". In my case I needed a starting capacitor, but couldn't find one with the necessary specifications, so I selected this one, which is a "run" capacitor. It solved my problem, so I seem to have learned that a "run" capacitor can provide a suitable replacement for a "start" capacitor.

Exactly What I Needed To Get My Pool Pump Operational Again

Our pool pump (A.O. Smith) would just hum very loud but wouldn’t turn or pump water. I thought it might be time for a new pump as we had no idea how long the current one has been in service. We did some researching on the internet to trouble-shoot the problem. I found some YouTube videos, and they helped us diagnose the problem as a bad capacitor. I was unable to find the exact same brand name capacitor that was taken out, but the specs on this one were the same as the old one. I ordered Thursday, and it arrived Saturday. It was a very simple installation too; plugged it in and worked! Like I mentioned above, there are some videos out there that show you how to change this part. It’s definitely worth your time to research before forking over big bucks for a new pump. Eventually, we want to change out our old pump for a newer more energy efficient one. But this quick fix will tide us over until we’re ready for that purchase. Go to TEMCo’s website to learn more about capacitors if you’re interested in such things. They seem to enjoy explaining what’s what. This capacitor may save you from having to buy a new pool pump motor until you’re ready.

Fast DIY Fix for Locked-up Pool Pumps

Does your pool pump just buzz and not turnover? Are you horrified at the $600-$800 that your pool guy wants to charge you to replace it? DON'T PANIC! This is an easy fix for the most common problem with pool pumps; a bad capacitor. Fixed mine in less than 2 hours and it is up and running like a champ. The photo shows how to tell if your capacitor is bad; note the top is clearly bowed outward and the terminals are no longer level. That is a normal failure function; the top bows which breaks the internal contacts. 1) Don't get bogged down in finding an exact replacement for your 20 year old capacitor; you won't. Just be sure the voltage and MFD (uf) rating match and you'll be good to go. 2) Watch a YouTube video for instructions on pulling your specific type of pool pump. Get a tube of gasket lube so you can re-lube existing gaskets when re-assembling. 3) Drain the charge from the old capacitor BEFORE you grab it. You really don't want to get a nasty shock. It is easy to drain the charge, not dangerous, and also on YouTube. Just short a screwdriver across the terminals. Wear gloves and eye protection just in case. 4) Re-assemble, re-connect, and fire it up! Once you have it pulled, you may want to buy replacement gaskets if they are badly worn or falling apart. You can do a little more disassembly to replace the shaft seals, however, if the motor wasn't noisy or dripping water before this event, I wouldn't worry about it. $15 versus $600; this was a no brainer!

Affordable replacement for pool pump motor

10 year old Jandy 2 HP pump motor stopped working suddenly and was humming and tripping the thermal protection. AC induction motors are notoriously tough on their "run capacitors" and these are expected to expire after a period of run time. There is special bulge on the top of the pump motor that is easily removable with 2 screws that houses the capacitor. Annoyingly they don't list the capacitor size on the pump label, so you have to disassemble just to read what size it is. It is VERY important to get an exact size match on the replacement. In this case it is 50 microfarads (uF). And of course, you must be certain the power is off. 230v AC can kill. Motor: Century Centurion A.O. Smith, Part# 7-193994-06 The real test will be to see how long this capacitor lasts compared to the original factory part. I'll update this review if it fails early, but for now the pump is back in action.

and an easy swap. Well worth the risk for this price

Had pool motor fail to start, older motor about 10 years old at least. Talked to electrician friend of mine on the phone and he said likely this part just failed, and not pump. Went to local pool supply chain with the old part, and they said they would order, and it was about a week to deliver, and it was about $100. I bought it on Amazon, and from time of delivery to pool pump running, was 10 minutes, and that included me drinking some iced tea while I installed it. Literally only two wires on top. I am buying a spare one now to have on hand. Saved me from paying too much , and an easy swap. Well worth the risk for this price.

Shockingly good value

All local suppliers of this capacitor wanted 3x or more over the Amazon/TEMCo price. I thought the rule of thumb was just to double out of pocket cost when reselling. Guess I'm behind the times.......no, wait, I'm a modern consumer and got the best price, good delivery and didn't have to put on pants and drive for 45 minutes to get it purchased.
