Solved ! Central Pneumatic 67708 10 gal compressor quit during use, breaker blown

by Barrie
(MA)

Breaker reset, only hum, no run, then breaker blows again. Only had about an hour of use since new, but out of 90 day warranty. Read about similar compressors having starting cap problems on this site, decided to check it; removed plastic air shroud, then cut tie to remove cap for test. Found ring terminal connecting wire to cap was broken off. Replaced terminal, with SOLDERED joint, new shrink sleeve. Ran perfectly! HOPE it holds, but there must be LOTS of vibration to have broken original wire in one hour. THANKS for keeping this site up. It gave me the idea that saved my compressor!

You are most welcome. Glad it was of help.

Central Pneumatic model 95498 air compressor runs a few seconds and stalls.

by Robert Hatcher
(Norwich, CT, USA)

I’ve had this compressor for about a year and a half. It has always been hesitant about running, runs a few seconds and the stalls as if the motor is binding.

When it stalls it will hum and sometimes go ahead and run or Ill head a little kick (like a thermal limiter on the motor?) and it will stop completely, even with voltage going to the motor from the pressure switch.

After a while, 5-20 min, it will just start, or try to start again.

Lately it has gotten worse and today I cannot get it to consistently recharge the tanks. It’s not cold out, its 84f and humid today.

This is a cheap compressor from harbor freight and I guess it’s just a crappy motor set up.

I’m just about ready to trash it and get a better model although it’s not in the budget at the moment. That is unless I can get around it.

Hello Robert...

As a comment here, please tell me how you are getting power to your air compressor, what other items are pulling power from the same circuit as the air compressor is on, and the amperage of the fuse or breaker.

pressure switch for central pnuematic... 95386

by Grady
(Mercedes, Texas)

I am trying to get a replacement switch for what I think is the pressure switch... Hongmao S-0712 or HM SCP-7A.

Can you tell me where I can get it and / or what is the replacement part number.

Thanks & regards,

gy

Grady, there is a manufacturer of pressure switches in China by the name of Hongmao.

If it is a pressure switch on your CP compressor you are trying to replace, you need not use the same OEM model. Get one that...

1) fits on your compressor
2) has the same voltage capability
3) interfaces properly with the unloader valve

If you are not sure about any of the above, all the information is found on this site.

I recently added a store to the top of the side columns, and in that store are a broad range of pressure switches. I am sure one will suit your Central Pneumatic air compressor, but first, you need to know what the specs of your present one are.

Central Pneumatic Air Compressors Model 95275 will not turn on

by Steven F. Trimarco
(Edinburg , Texas)

Hi,

My Central Pneumatic Air Compressors Model 95275 worked fine for 6 months. However, after that it would not turn on. I switch to other outlets throughout the house and still will not turn on as if it not getting any electric.

I only paid 40 dollars for it and wondering if it is cheaper to buy another one or buy a part, and if it worth buying a part what part do I need ?

I thank you in advance for any help you can provide me!

Sincerely,
Steven F. Trimarco

Well Steven, it's pretty hard to beat a price of $40 for a compressor, when it's hard to get any part at that same price level.

However, I'm not getting enough information about what your air compressor is or isn't doing on startup to be able to help you determine what the cause might be.

Please see the troubleshooting section on the sitemap page, and follow the link to the page about why air compresors won't start. There are checks there, and once you've done them, add a comment here with what you found if you haven't already figured it out.

Cheers,

Bill

The compressor does absolutely nothing when turning it on
by: Anonymous

Hi Bill,

Thank you for a quick response. The compressor does absolutely nothing when turning it on. I hit the reset button with no better results.

I have put in several electrical outlets without it turning on; it is as if I never plug it in at all.

I only paid $40 new -> Central Pneumatic Air Compressors Model 95275. So once again it may not be worth fixing and just buy another one ?

Sincerely,
Steven F. Trimarco

You need to do some tracing to see if the power is getting to the compressor, and then where that power goes after it gets there.

There is an internal pressure switch on this model, I believe, though I was not able to get a decent photo of the compressor to be sure.

If tracing the power flow with a multi-meter isn't your thing, and knowing that the basic pressure switch is $20 and up, then maybe a new one is in order? If you do get a new one, keep the parts from this one as spares, the gauges, the regulator and so on.
