Firebox, ring and fire grate

Cracks in the firebox or ring

• One piece, no panels. The Joe Jr.'s firebox is one ceramic bowl (KJ-CFB13) under one ceramic ring (KJ-CFR13). A piece broken through means that whole piece. There are no gaps between walls to worry about.
• Hairline cracks that leave it whole: Kamado Joe gives no rule for the Joe Jr. Owners report cracks are common on small one-piece fireboxes; one that still holds together keeps working.
• The ceramic carries a limited lifetime warranty for the original, registered buyer.

Change the firebox or the ring

The assembly order in reverse, with Kamado Joe Europe's fix for a wobbly firebox (Classic II).

1. With the grill cold, lift out the cooking grate, the deflector and the accessory rack.
2. Lift off the fire ring.
3. Lift out the fire grate.
4. Lift out the firebox with both hands.
5. If the new firebox rocks on the uneven floor of the grill, put a washer or a wood chip under its foot (Kamado Joe Europe).
6. Set the firebox in with its cut-out lined up with the draft door, then refit the ring, the fire grate, the rack, the deflector and the grate.
