Possible Causes
Tripped or faulty breaker, Loose line connections at terminal block, Open internal fuse (if equipped), Failed low‑voltage power supply on control board
How to Fix / Troubleshooting
Safety: Use proper PPE when working in the electrical panel. Turn OFF the main breaker if removing panel covers.
- Check breaker: Verify the dedicated 2‑pole breaker is in the ON position and has not tripped. Reset once if tripped.
- Measure voltage: With a multimeter, confirm correct voltage at the Grizzl‑E input terminals. If no voltage, troubleshoot upstream wiring and breaker.
- Inspect internal fuse: With power OFF and cover removed, look for an internal fuse on or near the control board. Test and replace if open with the same type and rating.
- Board failure: If supply voltage is present and any fuse is good but the unit remains dead, the internal power supply on the main control board has likely failed and the board must be replaced.
