This page is a community for our customers, employees, partners and anyone who is interest . I have voltage, cap is good (though it's a 50mfd 370, and york dealer told me should be 60-70). Check for proper system charge and pressure operation, which will allow the compressor to run at optimum conditions., In the end, Edwards said, even small changes in operating condition can lead to real improvements in operational efficiency.. stream zOq",4+Y~+]1^A"TVUYVZZ>y. In addition, a very simple diagnostic is to input real live conditions into our software and compare the measured amp draw and discharge gas temperature to expected values. For example, oil that is brown and overheated may indicate the compressor is overheating. The following overview shows an example of the structure of the nomenclature for a fixed-speed scroll . Start both compressors, amperage is balanced and within tolerance, both compressors. Compressors are equipped with internal overload devices which open on a rise in temperature. "If history repeats itself I am so getting a dinosaur". The internal overload is wired in series with both the start and run winding which prevents the compressor from coming on. 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. 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.
