Smoke generator does not advance bisquettes at all; no clicking or movement.

Safety first: Unplug the smoke generator before opening its housing. Keep hands clear of moving parts when testing.

Steps to diagnose:

• Check manual advance: Press the manual advance button (if equipped). Listen for any motor noise or clicking. No sound suggests a motor or board issue.
• Inspect for jams: Remove all bisquettes and check the feed track and push plate for obstructions. Clean out ash and debris.
• Open smoke generator: Remove the cover to access the motor and wiring. Ensure all connectors are firmly seated.
• Test motor continuity: Disconnect the motor and measure resistance across its terminals. An open circuit indicates a failed motor that must be replaced.
• Board output check: If the motor tests good, the smoke generator control board may not be sending power. Replace the smoke generator assembly or board as supplied by Bradley.
