Cracked fire brick on Harman P38

[m159267]

Just went to clean the stove and there it was. Obviously a result of my last burn several days ago. There was no indication of a crack prior to this. Stove is about 6 years old. Is there a problem burning with a crack of that size? I realize the brick will have to be replaced but is it usable until then? If anyone has replaced a brick how much of a job is it? Appreciate your time...

Looks like regular fire brick. I had a bunch of cracked ones in a wood stove I had and it was no problem. Seems like you are missing a few there. They only cost above five bucks per. I would burn with it cracked if it was my stove.

The brick are set into a channel that is snug but not real tight. Very easy to replace. Brick are there to help keep the rear hopper from getting to hot. I wouldn't fire it full bore. Local Menards had them for reasonable price.
