CAPACITY START WINDING MOTOR PROTECTION ON SINGLE PHASE MODELS. This is a bad thing to happen to your system the compressor will have to be changed and the refrigerant lines will need to be cleaned. 91 To 6. Like heat pumps and even some air conditioners. Open circuit in compressor start wiring. For years evaluate compressor motor windings. Producer Copeland. Experience shows that more than one third of compressors are. The relay s contacts open when current drops as the compressor comes up to speed and the start winding is disconnected from the motor circuit. However each make model and size compressor will yield somewhat different values. The refrigerator compressor fan is an indispensable part of the system you probably know that whenever you have any electric or electronic machine that works on a processor the fan is necessary to cool the system down and prevent problems such as overheating. However most megohmeter manufacturers publish guidelines that apply to open motors. Runs won t pump. 41 Ohm 23. Both windings are connected internally at one end to provide a common lead and when starting both are energized in parallel. Table 1.
