How to Fix / Troubleshooting
Safety first: Unplug the Granitestone air fryer before any disassembly. If you smell burning or see smoke, do not attempt repair; consult a professional.
Steps to troubleshoot no power:
- 1. Verify outlet: Test the wall outlet with another appliance. Reset any tripped breakers or GFCI outlets.
- 2. Inspect power cord: Check the power cord for cuts, frays, or crushed sections. If damaged, the cord must be replaced; do not tape or splice it.
- 3. Check cord connection inside: Remove the housing and locate where the cord connects to the AC input terminal block or directly to the control PCB. Ensure screws are tight and wires are secure.
- 4. Internal fuse: Many Granitestone models have a small glass or ceramic fuse on the control PCB. Inspect it; if visibly blown or open (test with a multimeter), replace it with the same type and rating.
- 5. Inspect PCB: Look for burned traces or components in the power supply section. If present, replace the main control PCB.
- 6. Reassemble and test: After replacing any fuses or boards, reassemble fully before plugging in and testing.
