TEST OR INSPECTION
3. VENTILATING AIR MOTOR APPEARS TO SLOW DOWN.
Disconnect red wire (1) from ventilating air motor (3) at quick disconnect
terminal (2). Pull boot (4) away from ventilating air motor capacitor (5) and
disconnect white wire (6) from capacitor.
Check voltage across red and white
wires back to PC board for 110 V ac. Place probes of volt ohmmeter in
contact with terminal (2) of red wire and terminal of white wire. Plug power
cable into POWER RECEPTACLE and move HEATER-OFF-FAN switch
quickly from OFF to HEATER to OFF while observing meter. Meter should
indicate at least 110 V ac.
If voltage is less than 110 V ac, correct power source.
