The Ways An Air Conditioner Compressor Can Fail
Forced air system blowers typically bomb because of one of two circumstances: time and active times (break down), or misuse. There are a few disappointments that can happen somewhere else in the framework that will cause a blower disappointment, however these are more uncommon except if the framework has been significantly manhandled. Generally misuse is an aftereffect of expanded running with inappropriate freon charge, or as a result of ill-advised help en route. This ill-advised assistance can incorporate cheating, undercharging, introducing some unacceptable starter capacitor as a substitution, eliminating (rather than fixing/supplanting) the warm limiter, deficient oil, blending contradictory oil types, or wrong oil, introducing the blower on a framework that had a significant burnout without finding a way appropriate ways to eliminate the corrosive from the framework, introducing some unacceptable blower (excessively little) for the framework, or introducing another blower on a framework that had some other disappointment that was rarely analyzed. The blower can fizzle in just a small bunch of various ways. It can bomb open, fizzle shorted, experience an orientation disappointment, or a cylinder disappointment (toss a bar), or experience a valve disappointment. That is basically the whole rundown. Whenever a blower bombs open, a wire inside the blower breaks. This is unserviceable and the manifestation is that the blower doesn't run, however it might murmur. Assuming the blower bombs open, and following the means here doesn't fix it, then, at that CÔNG TY TNHH HTECH VINA point, the framework might be a decent possibility for another blower. This disappointment causes no further disappointments and won't harm the remainder of the framework; on the off chance that the remainder of the framework isn't bedraggled then it would be practical to simply placed another blower in. Testing for a bombed open blower is simple. Pop the electrical cover for the blower off, and eliminate the wires and the warm limiter. Utilizing an ohmmeter, measure the impedance starting with one terminal then onto the next across each of the three terminals of the blower. Additionally measure the impedance to the instance of the blower for every one of the three terminals. You should peruse low impedance values for all terminal to terminal associations (two or three hundred ohms or less) and you ought to have a high impedance (a few kilo-ohms or more prominent) for all terminals to the case (which is ground). In the event that any of the terminal to terminal associations is an exceptionally high impedance, you have a bombed open blower. In exceptionally intriguing cases, a bombed open blower might show a low impedance to ground from one terminal (which will be one of the terminals related with the bombed open). For this situation, the messed up wire has moved and is reaching the situation. This condition - which is very uncommon however not feasible - could make a breaker trip and could result in a misdiagnosis of bombed short. Be cautious here; do a basic analysis of the substance of the lines prior to choosing how to continue with fix. At the point when a blower flops short, what happens is that protection on the wires has worn off or consumed off or broken inside the blower. This permits a wire on an engine twisting to contact something it ought not touch - most ordinarily itself a turn or two further along on the engine winding. This outcomes in a "shorted winding" which will stop the blower right away and influence it to warm up and consume inside. Terrible direction can cause a flopped short. Either the rotor wobbles to the point of reaching the stator, bringing about protection harm that shorts the rotor either to ground or to the stator, or end bearing wear can permit the stator to move down over the long haul until it starts to rub against the stator closes or the lodging. Generally when one of these shorts happen, it isn't quickly a hard short - implying that at first the contact is discontinuous and travels every which way. Each time the short happens, the blower force drops strongly, the blower might shiver a piece noticeably therefore, and this shiver shakes the twisting to the point of isolating the short. While the short is set up, the current through the shorted wrapping shoots up and a ton of hotness is created. Likewise, normally the short will blow a few sparkles - which produces corrosive inside the climate control system framework by decaying the freon into a combination of hydrochloric and hydrofluoric corrosive. Over the long run (conceivably a long time, typically less) the shivering and the igniting and the hotness and the corrosive reason protection to flop quickly on the winding. Eventually, the winding loses sufficient protection that within the blower is in a real sense consuming. This will just happen for a couple of moments however in that time the blower obliterates itself and fills the framework with corrosive. Then, at that point, the blower stops. It might around then soften a wire free and short to the lodging (which can trip your home primary breaker) or it may not. Assuming the underlying reason for the disappointment was awful course making the rotor rub, then, at that point, generally when the thing at long last passes on it will be shorted to the lodging. Assuming that it shorts to the lodging, it will blow wires as well as breakers and your ohmmeter will show an exceptionally low impedance from at least one windings to ground. On the off chance that it doesn't short to the lodging, then, at that point, it will stop. You actually lay out the kind of disappointment utilizing an ohmmeter. You can't straightforwardly determine a bombed short to have an ohmmeter except if it shorts to the lodging - a shorted winding won't appear with an ohmmeter however it would with an inductance meter (yet who has one of those?) Instead, you need to surmise the flopped short. You do this by laying out the ohmmeter gives typical readings, the starter capacitor is great, power is showing up at the blower, AND an analysis of the freon shows corrosive present. With a flopped short, simply surrender. Make a huge difference, including the lines if conceivable. It does not merit fixing; it is loaded with corrosive and in this way is all garbage. Further, a flopped short might have been at first incited by another disappointment in the framework that caused a blower over-burden; by supplanting the entire framework you likewise will dispose of that possible other issue. Less regularly, a blower will have a direction disappointment, cylinder disappointment or a valve disappointment. These mechanical disappointments typically signal break down yet could flag misuse (low oil levels, warm limiter eliminated so blower overheats, constant low freon condition because of un-fixed spills). All the more once in a while, they can flag one more disappointment in the framework, for example, a turning around valve issue or an extension valve issue that breezes up allowing fluid freon to get into the pull side of the blower. Assuming a heading comes up short, as a rule you will know in light of the fact that the blower will seem like an engine with a terrible bearing, or it will secure and decline to run. In the most pessimistic scenario, the rotor will wobble, the windings will rub on the stator, and you will end up with a flopped short. Assuming that the blower secures precisely and neglects to run, you will know since it will buzz uproariously for a couple of moments and may shiver (very much like any slowed down engine) until the warm limiter cuts it off. At the point when you do your electrical checks, you will track down no proof of bombed open or flopped short. The analysis will show no corrosive. For this situation, you could make a decent attempt start unit however assuming that the blower has bombed precisely the hard-start pack will not get the blower to begin. For this situation, supplanting the blower is a decent arrangement inasmuch as the remainder of the framework isn't incapacitated. In the wake of supplanting the blower, you should cautiously dissect the presentation of the whole framework to decide if the blower issue was incited by something different. Once in a blue moon, the blower will encounter a valve disappointment. For this situation, it will either stay there and seem to run cheerfully however will siphon no liquid (valve won't close), or it will secure because of a failure to move the liquid out of the pressure chamber (valve won't open). In the event that it is running cheerfully, whenever you have laid out that there is for sure a lot of freon in the framework, however nothing is moving, then, at that point, you must choose the option to change the blower. Once more, a framework with a blower that has had a valve disappointment is a decent contender for another blower. Presently, in the event that the blower is precisely secured it very well may be a direct result of two or three things. On the off chance that the blower is on a hotness siphon, ensure the switching valve isn't stuck midway. Additionally ensure the extension valve is working; on the off chance that it is obstructed it can lock the blower. Additionally ensure the channel isn't obstructed. I once saw a framework that had a locked blower because of fluid lock. Some numbskull had "overhauled" the framework by adding freon, and adding freon, and adding freon until the thing was totally loaded with fluid. Trust me; that doesn't work. Should determination show a stopped up channel, then, at that point, this ought to be taken as certain proof of some disappointment in the framework OTHER than a blower disappointment. Commonly, it will be metal sections out of the blower that stops up the channel. This can occur assuming something is making the blower wear quickly, especially in the cylinders, the rings, the bores, and the direction. Either the blower has immeasurably deficient oil OR (and all the more regularly) fluid freon is getting into the blower on the pull line. This conduct should be halted. Take a gander at the extension valve and at the turning around valve (for a hotness siphon).
