In this guide, we’ll walk you through a step-by-step process on how to replace the ceramic burner tile in various Mr. Heater models.
Whether you own a Mr. Heater Buddy, Little Buddy, Hunting Buddy, or Big Buddy, this guide will provide you with a clear pathway to restoring your heater to its prime condition, ensuring many more warm and comfortable days ahead.
Quick answer: To replace your Mr. Heater Burner tile, you’ll need to buy a replacement burner tile kit for your Mr. Heater model. Then, you can disassemble your heater, loosen the bracket holding the ceramic tile, and replace the tile and the gasket.
Steps to Replace Your Mr. Heater Ceramic Burner Tile
1. Look up the Model Number of your Mr Heater
First of all, you need to buy the necessary replacement parts. But replacement parts are often labeled using the official model number.
So, let’s first look up the model number of your Mr. Heater model:
|Mr. Heater Model||Model Nr.|
|Mr. Heater Little Buddy||MH4B|
|Mr. Heater Buddy||MH9BX|
|Mr. Heater Hunting Buddy||MH12B|
|Mr. Heater Big Buddy||MH18B|
If your model is not on the list, look it up directly on the back side of your Mr. Heater unit.
Or, alternatively, look up the model number on a sales page of your Mr. Heater model. On Amazon, you’ll usually find the model number in the description of the heater.
2. Get a Replacement Burner Tile and Gasket
For a complete burner tile replacement, you’ll need
- a fitting replacement burner tile and
- a burner gasket (the old one is likely burnt and can’t be reused)
The burner burner gasket is a piece of felt that insulates gas leaks.
Usually, the tile and the gasket are sold together in a kit. If you can’t find a kit, you can also buy them separately.
If you live in the US, buy from the official Mr. Heater website.
Often, on the official website, replacement parts are out of stock. Or, if you live overseas, possibly you can’t order at mrheater.com directly
If your replacement parts are out of stock or you live overseas and can’t place an order at mrheater.com directly, you can check out Mr. Heater replacement parts at lioncove.ca.
3. Disassemble your Mr. Heater unit
Once you have the replacement parts for your Mr. Heater, you’ll need to disassemble it to access the ceramic burner tile.
The disassembly varies from model to model:
Here are quick instructions for the Buddy and Big Buddy models. The Hunter Buddy is probably similar.

4. Replace old burner tile
To replace the old burner tile, gently remove it from its bracket. Likely, you’ll need to loosen the bracket using one or two screws responsible for tightening and loosing which sit at the bottom of the contraption.
Remove the old burner tile. Scrape out the old gasket. Likely it’s burnt and falls apart.
Put the new felt gasket in place.
After that, position the new burner tile in the bracket ensuring it sits flat and snug.
Once the new burner tile is in place, tighten the bracket screw securely to hold the burner tile in place. Ensure it’s well-secured but not overly tightened to prevent any damage to the new tile, especially when it heats up.
5. Reassemble your Mr. Heater
Now, it’s time to reassemble the heater. Follow the disassembly steps in reverse to put your heater back together.
Start by securing the front panel, then reattach the handle using the screws you had removed.
Ensure all screws are tightened securely but not overly so to avoid damaging the heater.
6. Test the Heater
After you’ve successfully reassembled your Mr. Heater, it’s crucial to test it to ensure the burner tile replacement was successful and that the heater operates correctly.
Turn on your Mr. Heater and observe the flame. It should ignite smoothly and produce a clean, blue flame.
If it doesn’t, double-check your work to ensure everything has been reassembled correctly. You can cross-check with this guide: How to fix a Mr. Heater Buddy not lighting

In conclusion, replacing the ceramic burner tile in your Mr. Heater is a straightforward task when you follow the correct steps.
