CORRECTIVE ACTION
Step 2. Test ventilating air motor capacitor,
Pull capacitor boot away from end of
capacitor (1 ). Tag and disconnect brown wire (2) and two white wires (3 and
4). Set volt ohmmeter on R x 100. Put one probe against each capacitor
terminal (5 and 6). Meter should indicate infinity. Reverse probes. Reading
should jump to 15,000 ohms and immediately fall back to infinity, If meter
fails to react as described, capacitor is defective.
Replace defective capacitor (1 ). Loosen screw (7) and pull capacitor
out of mounting bracket (8). Slide new capacitor into mounting
bracket, tighten screw, and connect brown wire (2) and two white wires
(3 and 4) to capacitor. Position boot over end of capacitor.
