  If your Grizzly Power Tool doesn't start or a breaker trips, here's what to check: * Make sure the disabling key is inserted and working. If not, insert or replace it. * Verify you're using the correct power supply voltage and circuit size. * Check for tripped circuit breakers or blown fuses. Ensure the circuit is correctly sized and free of shorts. Reset the breaker or replace the fuse. * Inspect the motor wiring connections. Correct them if they're incorrect. * Look for broken, disconnected, or corroded wires and fix them. * Test and replace the start capacitor if it's faulty. * Adjust or replace the centrifugal switch if it’s faulty (if available). * Test, repair, or replace the motor if it’s faulty.

Why does my Grizzly G7945 not start or trip the breaker?
- V
  Vickie JohnsonSep 10, 2025
  If your Grizzly Drill machine doesn't start or the breaker trips, several factors could be at play. First, check the power plug and receptacle to ensure they are making good contact and are wired correctly. A faulty start capacitor could also be the culprit, requiring replacement. Ensure the motor connection is correctly wired. Verify that all hot lines and grounds are operational and have the correct voltage. Other potential issues include a faulty safety switch key or ON/OFF switch, both of which may need replacement. Inspect the cable and wiring for breaks or high resistance, repairing or replacing as necessary. Finally, the motor itself might be at fault, requiring testing, repair, or replacement.
