Una vez que la velocidad del compresor sea &gt;400 rpm, el compresor tiene hasta 30 segundos para aumentar la diferencia de presi\u00f3n (presi\u00f3n de descarga \u2013 presi\u00f3n de aspiraci\u00f3n) en 20 psi. Si esta diferencia de presi\u00f3n no se alcanza, el c\u00f3digo 38-54 se activar\u00e1 mediante una operaci\u00f3n de bloqueo durante 30 minutos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La causa m\u00e1s probable de este fallo es que los cables del compresor est\u00e9n conectados de forma incorrecta. Compruebe los colores de los cables con el diagrama de cableado para asegurarse de que los cables UVW est\u00e9n conectados a los terminales correctos. Es menos probable, pero a\u00fan as\u00ed posible, que se rompa el eje del motor del compresor, lo que permitir\u00eda que el motor del compresor gire pero que no est\u00e9 conectado al mecanismo de compresi\u00f3n.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fallo del motor del ventilador Informaci\u00f3n general<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">El motor de ventilador utilizado en estos modelos requiere 5 cables. La alimentaci\u00f3n de 240~373 VDC se realiza a trav\u00e9s del conector de 3 pines (VDC) del pin 1 y del conector de 4 pines (GND) del pin 1. El conector de 4 pines del pin 2 es la se\u00f1al Vcc para el suministro de energ\u00eda del IC (~15 Vdc). El conector de 4 pines del pin 3 es la se\u00f1al Vsp, que es un control de velocidad de entrada de 0 a 5 Vdc. El conector de 4 pines del pin 4 es el FG o se\u00f1al de retroalimentaci\u00f3n, enviando informaci\u00f3n de rpm de vuelta al VFD. El motor se controla mediante un control en bucle cerrado, en el que la velocidad variable se incrementa o disminuye mediante el VFD dependiendo del comando de RPM procedente del PCM al VFD, junto con la informaci\u00f3n real de rpm obtenida a trav\u00e9s del pin FG. Para confirmar la presencia de da\u00f1os en la electr\u00f3nica del motor de ventilador, consulte la tabla 6. Nota: No se puede medir la resistencia de los bobinados del motor de ventilador debido a la electr\u00f3nica incorporada. Nota: La resistencia es aproximada; la temperatura puede afectar las mediciones, por lo que solo declare el motor como defectuoso si los resultados difieren significativamente de los valores de la tabla 6. Aunque el motor del ventilador tiene protecci\u00f3n interna contra la corriente, en el VFD se encuentra un fusible reemplazable externo para proteger contra cortocircuitos. Consulte el diagrama de cableado para conocer las especificaciones de reemplazo del fusible.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<p
