I would definitely replace it!
You don't want it to weaken & maybe fall out when no one is around, or let CO gas leak into the house at night.
If nothing else, it's just not worth the loss of peace of mind.
(the same thing happened to my Harman TLC two years ago & I didn't want to chance keeping it going. I replaced the glass itself & bought an additional whole new door/window assembly from my Harman dealer. If it happens again, I wont even have to shut down now....I'll just take out 2 hinge pins & replace the whole door
Make sure you use the correct glass too! (It's ceramic based I think....& expensive!)
