• Argo Clima AWR512CL, 11-2. Checking Motor Capacitor Remove the lead wires from the capacitor terminals, and then place a probe on the capacitor terminals as shown in Fig. 5. Observe the deflection of the pointer, setting the resistance measuring range of the multimeter to the maximum value. The capacitor is “good” if the pointer bounces to a great extent and then gradually returns to its original position. The range of deflection and deflection time differ according to the capacity of the capacitor. 34 Multimeter Ω Compressor motor capacitor Fan motor capacitor Fig.5
