Ch21 refers compressor runs high current. Due to 1. Condenser coil dust blocked- Clean it. 2. Condenser fan motor less rpm or struck- Replace capacitor or motor. 3. Compressor windings weak- Check by ohms. If single phase, the ohms of SR should be the total of CS & CR. If 3 ohase all winding ohms should be equal (1 &2, 1&3, 2&3). If not replace compressor. Thanks and hope helpful.
