A vehicle's A/C system consists of a number of components, including the A/C compressor. The A/C does not cool without a working compressor, and the compressor does not function properly without a working A/C compressor clutch. In order to properly diagnose and fix problems associated with an A/C compressor clutch, consumers should develop a basic understanding of how the system works. Otherwise, they could spend time and money purchasing the wrong parts when they could have conducted some simple A/C compressor clutch diagnostics. The A/C compressor is essentially the working core of a vehicle's A/C system. When consumers turn on their A/C units, the A/C compressor starts to compress refrigerant in the system. This compression creates high pressure and raises the temperature of the refrigerant before it enters the A/C condenser. The A/C compressor clutch is in charge of alerting the compressor to start this compression. In other words, the compressor clutch is responsible for communicating to the A/C compressor when to start and stop operating.

The A/C compressor clutch actually has multiple components. Once the A/C system activates, the compressor clutch pulley starts to rotate the compressor clutch hub, which is a round metal piece located at the front of the clutch. The compressor's belt rides along the pulley. The compressor clutch hub attaches to the compressor shaft, which starts to rotate, creating both suction and discharge. The compressor's belt then forces the compressor clutch pulley to rotate, and that causes the compressor clutch coil to pull the hub against the pulley. The compressor clutch coil is tightly wound copper wire found below the pulley that acts as an electromagnet. These combined actions allow the A/C compressor clutch to engage the compressor and turn on the A/C. A lot of common A/C problems originate with the A/C compressor and the compressor clutch. However, before jumping to any conclusions, consumers should attempt to rule out any issues that could merely require simple fixes. If the A/C blows only moderately cool air when the temperature setting is at the coldest, owners can check a couple of things.

First, they need to ensure the cooling fans on the A/C radiator and A/C condenser work properly. They also need to look for debris that might be blocking the A/C condenser and keeping cold air from passing over it. outside ac unit iced overFinally, consumers should check the cabin air filter to ensure it is free of debris and contaminants.1 kw ac unit Although a completely non-working A/C system could certainly indicate a serious problem, sometimes another culprit exists. carrier hvac parts cross referenceConsumers should examine A/C systems to determine that no breakers or fuses have tripped or blown because those issues prevent power from running through the A/C system. A/C compressor clutch problems regularly occur when routine maintenance does not take place on the vehicle's A/C system.

As a result, the A/C compressor clutch is often to blame for common A/C problems. Suction pressure is too high Discharge pressure is too low Compressor delivers inconsistent pressure to the refrigerant Addition of a shim to close air gaps between the hub and pulley Replace A/C compressor clutch If A/C compressor has voltage, probably defective compressor clutch Replace A/C compressor clutch A/C compressor clutch coil receiving inadequate voltage Overheating of internal winding Slippage of hub against the pulley A/C compressor clutch may have a defective pulley bearing With regards to most of these issues, the best solution is often to replace the A/C compressor clutch. However, qualified technicians are sometimes able to replace or fix individual components within the A/C compressor clutch. eBay has a wide selection of A/C compressor clutches and its components for purchase from a variety of reputable sellers, including clutches and related parts made by top brands like AC Delco, Motorcraft, and Four Seasons.

Search for the exact A/C compressor clutch part you need and then narrow down your search results by price, condition, or even the location of the seller. Before making a purchase, be sure to check out eBay's deals on car and truck parts to see if you can find what you need at the lowest possible price. Belt Drive Fan Coils 600 to 4,000 Cfm The 42B belt drive fan coil units provide year-round comfort air conditioning with central station operating economy. The 42B units are designed for high-static, ducted applications, using furred-in, horizontal and vertical models Greater Flexibility is in the AirI don’t know about you but there’s something a little tedious about placing TENS pads on your own back, right? It’s not a major problem to me but it does seem like there should be a better, more efficient way of targeting the lower back. However, some people – for whatever reason – may find it incredibly difficult and in some cases, impossible to place electrodes on their own back.

Fortunately, there is a solution – the TENS belt, a simple product that wraps around the waist and connects to a main unit. If you’ve been put off by the thought of having to stick pads on your own back or prefer the idea of something more convenient, you may just like to take a look at the following 5 TENS belts. If you’ve read my review of the TENS 7000 device you’ll have a head start here. This particular setup costs only $15 more (at time of writing) and includes that very TENS unit, along with a belt and conductive spray. What I love best about this solution: Is the electrodes are built into and enclosed inside the belt. But what’s the big deal about that!? It means you don’t have the ongoing cost of replacement pads! Surely I’m not the only who thinks about saving some cash? The beauty of TENS 7000 To Go is that once you’ve made your initial investment, your running costs are minimal – with just the battery and conductive spray to think about.

The device itself is as powerful as OTC TENS units come, with an output range of 100 mA (you can read more about output levels here). It also boasts an excellent range of features that allow you to fine-tune settings – so you can get your TENS therapy just the way you like it. For waist sizes: up to 52 inches Battery: 1 x 9V Searching for a genuinely portable TENS belt setup? Then look no further. This package from HealthmateForever includes the iPod size HM8G TENS EMS unit and Multi Belt. HealthmateForever’s innovative little devices are feature-packed and come with a selection of wonderful accessories, you can find out everything you need to know about them in this post I wrote. Perhaps the most useful thing: Is that this machine is rechargeable. It ships with both a USB charging cable and AC adapter for the mains. I don’t know about you but if I’m going away the last thing I want to be stressing about is batteries for my TENS unit?

I’d much rather be able to throw the device and charging cable into my carry-on and know I can use it as soon as I need to. And if you’re somebody who fancies a workout, there’s a program you can use to build your abs! The belt has been designed so it can be used on the legs and arms – as well as the abs and lower back. Who knows, you may choose this machine to relieve lower back pain and also end up with a six pack! For waist sizes: One size fits all The Zewa SpaBuddy TENS unit is one of those wonderfully simple machines. SpaBuddy Relax includes the same impressive device as the SpaBuddy Sport (you can read the review here), plus the TENS belt. If you want a unit that’s easy to understand and operate, Zewa’s SpaBuddy Relax is worth a closer look. A useful feature with this product is the sizing: If you’re a little larger round the waist it shouldn’t be an issue – it extends up to 60 inches. As far as the device goes:

There are 8 preset programs and 30 intensity levels – so you’re spoiled for choice. Like TENS 7000, the SpaBuddy device has an output range that goes all the way up to 100 mA – so you won’t be short on power with this machine! For waist sizes: 22” to 60” Battery: 3 x AAA This neat looking belt and TENS device from ReVive has been created with the sole purpose of treating the lower back. What’s handy with this setup: Is the clip on the front so you don’t have to worry about somewhere to put the main unit. With this there’s added convenience – as it allows you to adjust the device during your treatment, without having to remove it from a pocket or pouch. The belt also offers lumbar support to help improve posture and mobility. There are only 3 present programs to choose from, whereas the other devices on this page all have more. Something it does has more of is intensity levels, a massive 99 to choose from! Those who have spent a bit of time on the site will know by now that:

The number of levels only relates to the amount of control over the intensity – and isn’t a reflection of how powerful the output is. What it does mean though, is you should never ever have a problem finding the right level. One last thing you may be interested in is the warranty – ReVive comes with two years cover, unlike a number of competing products that have only one. Not bad when you take into account the relatively low cost of the product. For waist sizes: 30” to 56 “ Want a 360° view of this TENS unit belt?
