How To Repair Masterbuilt 560 Firebox

Truth be told, your Masterbuilt 560 firebox is better to be replaced than repaired if there is an issue. I have suggested a very good replacement kit with the gasket material above. You can try this out.

Then again, if there are only minor holes or cracks, you can repair them as well. 

  • First, you must identify the damaged area to measure how severely the firebox is affected.
  • Then get some high-heat-resistant epoxy, one of the most reliable glues for metal coating.
  • Apply it evenly to the warped area. Then let it sit for a while to get hardened.
  • Finally, it’s time to test the repair. Heat the firebox and check if the glue holds or not.

If everything is okay, you can continue using the firebox until it gets extensively damaged.

However, it’s worth mentioning that this process only works to cover minor cracks. For significant damages, I still recommend replacing the unit with a new one.

How Do I Determine If My Masterbuilt 560 Firebox Needs Replacement?

The only tell-tale sign that your Masterbuilt 560 firebox needs replacement is the firebox malfunction.

If there’s suddenly excessive ash buildup in the firebox or you find it hard to maintain a consistent temperature in the grill, it’s perhaps the fault of the firebox. 

Sometimes, you will notice that your foods aren’t getting heated evenly. Again, there must be a malfunction in the firebox unit.

But how can you determine the damage? By inspecting the firebox unit thoroughly.

If you notice any crack, hole, warp, rust, or corrosion in the unit, probably it’s time to replace it.

Often, holes and cracks lead the firebox to significant heat loss. That badly affects your overall grill performance. 

Please remember that a faulty firebox can cause sudden flare-ups leading to potential fire hazards.

That’s why you should replace it as soon as you notice any visible damage.

Maintenance Tips For Ensuring The Longevity Of The Replacement Firebox

Well, the maintenance tips for Masterbuilt 560 firebox replacement are nothing new. You should follow the basic care and maintenance. 

After every BBQ session, make sure to clean the ash and food grease from the firebox. This is really important as excessive ash and grease buildup accumulates rust. 

Sometimes, you should remove the grill grates and ash pan to access the interior of the firebox. Then clean the interior thoroughly to make the unit long-lasting. 

Most importantly, don’t let the unit get exposed to excessive heat for a long period. This will accelerate the warping of the material.

Besides, you shouldn’t expose the firebox interior to water if you want to avoid rust and corrosion.

Finally, you should use high-quality charcoal for less ash buildup. Otherwise, the Masterbuilt 560 firebox, whether it’s the original or replacement unit, is bound to deteriorate sooner than expected.

Conclusion

That’s all about masterbuilt 560 firebox replacement. I hope this guide answers all your questions regarding firebox replacement in a gravity-fed Masterbuilt smoker. 

Whether you have a 560 or any other Gravity series charcoal smoker, you should replace the firebox with a suitable replacement kit if it starts malfunctioning.

But before you order a replacement, you should check if all the specs are compatible with your specific grill model or not.

Besides, regular check-ups and maintenance can prolong the lifespan of a replacement grill part, be it a firebox or anything else.
