The Ways An Air Conditioner Compressor Can Fail, and What To Do About It
Forced air system blowers more often than not flop because of one of two conditions: time and long stretches of activity (destroy), or mishandle. There are a few disappointments that can happen somewhere else in the framework that will cause a blower disappointment, however these are less regular except if the framework has been generously mishandled.

Generally manhandle is an aftereffect of expanded running with ill-advised Free on charge, or as a result of ill-advised administration en route. This inappropriate administration can incorporate cheating, undercharging, introducing the wrong starter capacitor as a substitution, expelling (instead of repairing/supplanting) the warm limiter, deficient oil, blending inconsistent oil composes, or wrong oil, introducing the blower on a framework that had a noteworthy burnout without finding a way to expel the corrosive from the framework, introducing the wrong blower (too little) for the framework, or introducing another blower on a framework that had some other disappointment that was never analyzed.
The blower can bomb in just a bunch of various ways. It can fizzle open, fall flat shorted, encounter a direction disappointment, or a cylinder disappointment (toss a bar), or experience a valve disappointment. That is essentially the whole rundown.
At the point when a blower comes up short open, a wire inside the blower breaks. This is serviceable and the manifestation is that the blower does not run, however it might murmur. On the off chance that the blower fizzles open, and following the means here does not settle it, at that point the framework might be a decent possibility for another blower. This disappointment causes no further disappointments and won't harm whatever is left of the framework; if whatever remains of the framework isn't run down then it would be practical to simply put another blower in.
Testing for a fizzled open blower is simple. Pop the electrical cover for the blower off, and evacuate the wires and the warm limiter. Utilizing an ohmmeter, measure the impedance starting with one terminal then onto the next over every one 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 read low impedance esteems for all terminal to terminal associations (a couple of 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 a high impedance, you have a fizzled open blower. In extremely uncommon cases, a fizzled open blower may demonstrate a low impedance to ground from one terminal (which will be one of the terminals related with the fizzled open). For this situation, the broken wire has moved and is reaching the case. This condition - which is very uncommon yet not feasible - could make a breaker trip and could result in a misdiagnosis of flopped short. Be cautious here; complete a basic analysis of the substance of the lines previously choosing how to continue with repair.
At the point when a blower bombs 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 contact - most usually itself a turn or two further along on the engine winding. This outcomes in a "shorted winding" which will stop the blower quickly and cause it to warm up and consume inside.
Terrible course can cause a flopped short. Either the rotor wobbles enough to contact the stater, bringing about protection harm that shorts the rotor either to ground or to the stater, or end bearing wear can enable the stater to move down after some time until the point that it starts to rub against the stater closes or the lodging.
Typically when one of these shorts happen, it isn't promptly a hard short - implying that at first the contact is irregular and travels every which way. Each time the short happens, the blower torque drops pointedly, the blower may shiver a bit obviously accordingly, and this shiver shakes the twisting enough to isolate the short. While the short is set up, the current through the shorted twisting shoots up and a considerable measure of warmth is created. Likewise, for the most part the short will blow a few flashes - which produces corrosive inside the forced air system framework by decaying the freon into a blend of hydroelectric and hydroelectric corrosive.
After some time (potentially two or three weeks, normally less) the shivering and the starting and the warmth and the corrosive reason protection to bomb quickly on the winding. At last, the winding loses enough protection that within the blower is actually consuming. This will just continue for a couple of minutes however in that time the blower pulverizes itself and fills the framework with corrosive. At that point the blower stops. It might around then liquefy a wire free and short to the lodging (which can trip your home primary breaker) or it may not. On the off chance that the underlying reason for the disappointment was terrible orientation making the rotor rub, at that point more often than not when the thing at long last kicks the bucket it will be shorted to the lodging.so most important think of The Ways An Air Conditioner Compressor Can Fail, and What To Do About It
