Possible Causes
Weak or cracked igniter, Gas valve not opening, Faulty flame sensor preventing gas release, Loose ignition wiring
How to Fix / Troubleshooting
Safety first: Turn off power and gas before servicing. If you smell gas, evacuate and call your gas supplier.
Steps to diagnose:
- Observe through sight glass: With panels in place, restore power and call for heat. Look for igniter glow or spark. If none, suspect the igniter or control board.
- Check igniter connections: With power off, inspect the igniter wiring for secure connections and damage.
- Test igniter: Measure resistance; replace if open or out of Jacuzzi’s specified range.
- Gas valve and control: If the igniter works but there is no flame or gas sound, a professional should test the gas valve and control board outputs.
