When a contractor is investigating potential electrical problems with the compressor, the usual methods of checking amp draw and line voltage at specific conditions is one of the best ways to determine if the compressor and system are operating properly, Lanzer said. If you would like to know more about megohm values of a compressor check out this application engineering bulletin https://webapps.emerson.com/online-product-information/Publication/LaunchPDF?Index=aeb&PDF=ae1294.pdf This can be due to excessive loads, poor airflow or lack of superheat. 2/6/2008 10:46:42 AM Keeping the compressor running efficiently ensures the entire system will be more productive. High amp draw may indicate a valve plate is broken. This may lead the technician to inspect the valve plates for damage, desuperheating devices, or evaporator/expansion valve function to possibly thwart an inevitable failure.. Before diagnosing the problem as a failed compressor, always allow the motor protector time to reset, usually until the upper housing is within 5F of ambient temperature (this can vary by unit); Check to ensure the resistance to the compressor shell is very high, which will make certain the compressor motor is not electrically grounded to the compressor mechanical; Ensure the compressor is connected to a power supply that delivers a good nominal (+/- 5 percent) voltage at the compressor power terminals; If troubleshooting a more advanced system, identify any conditions that are being reported by the built-in diagnostics system, and always follow manufacturer guidelines; and. Ensure filter dryers, all heat exchangers, and air filters in the system are clean and/or working as specified. 3 0 obj

A multimeter can be used to prove insulation is bad, but rarely guarantees a motor is good, due to its lower voltage output. By understanding the compressors operating pressures, amps, and voltages, these can then be used to determine if the compressor is operating properly by baselining these against the compressor performance guidelines. Often, compressor problems are a result of stress on the compressor motor that can be caused by a blocked fan or when a unit is overloaded, which can cause the compressor motor to draw high amperage, Pride said. For example, if the line voltage is below the recommended minimum for a particular compressors motor, this could then raise the motor amp draw and potentially cause the internal motor overload to open.

Enhancing food preservation around the world, Copeland Scroll Compressor Enhances Food Preservation Around the World. Sanchez said the level of testing and diagnostics depends greatly on the type of compressor, system, and application. With low sound andvibration from smooth scroll movement, this compressor is optimized for medium-temperature applications. Between the 3 terminals at the compressor I measured 1.4, 2.9, and 3.2 (s-r). These problems are resolved by checking the voltage going to the compressor, the electrical components, wiring to the components, and the resistance of the compressor motor windings., The most common compressor problems typically stem from a system component failure, said Lanzer. The lack of lubrication may have been caused by flooding of liquid refrigerant into the compressor which washed the oil away. And, protecting your reputation by selecting a compressor that is of the highest quality in the commercial refrigeration market. I did some winding checks on 4 & 5 ton scrolls today & got the following ohm readings: C-R 0.6. Check system operating pressures.
