Direct Air Motor Will Not Run; Direct Air Motor Will Not Run: No Headlights - Simplicity SYNERGY X9.5 Service Manual

B. Direct Air Motor Will Not Run
1. If nozzle cover is installed, the vacuum must be out of the upright position before the direct air motor will run.
2. If the nozzle cover is not installed, the direct air motor should run in the upright position.
3. .5 and newer models: If the belt is not installed, or the hall sensor is defective, the vacuum may run 2 to 3 seconds and then
cut off.
4. The handle should be attached to the vacuum and plugged into wall outlet. (See Figure A. Correct Handle Installation)
Check for headlights:
1. Direct air motor will not run. Clean air motor runs.
2. Turn the main power switch "ON", (green light in switch on) and the floor/carpet switch to the carpet position with green light
on. Note: these lights will be on any time the handle is plugged into the outlet and switches are turned "ON".
• No headlights: See Section B. 1. No Headlights.
• Headlights are on: See Section B. 2. Working Headlights
B.1. Direct Air Motor Will Not Run: No Headlights
B.1. Step 1.
1. Remove the dust cover then lay the vacuum face down.
2. Remove the nozzle cover (5 screws).
3. Place vacuum in the upright position and remove the 2 (two) screws from the assist spring.
4. Lay the vacuum flat and remove the direct air motor inlet cover - 3 (three) screws in the inlet cover.
5. Remove the 2 (two) screws on each side of the dust compartment in brackets.
6. Remove the motor cover (4 (four) screws).
B.1. Step 2.
Check the clean air motor tap wire voltage:
1. Place one lead from a multi-meter on the white motor wire connection, and one lead on the blue or yellow tap wire
connection. (See Figure F. Clean Air Motor Wiring or Figure G. Ametek Clean Air Motor Wiring)
2. Turn the vacuum "ON" with the main power switch. With clean air motor running, read the voltage on the meter.
3. If reading is 12 to 18 AC volts the clean air motor is good.
4. If voltage is less than 12 volts replace the clean air motor.
5. If voltage is 18 or more, check fuse on the PCB:
a) If fuse is faulty replace fuse and retest vacuum.
b) If fuse is good replace the PCB and retest the vacuum.
If vacuum still does not work properly continue through Section B.2. Direct Air Motor Will Not Run: Headlights are on:
