This comes up a lot here in Minnesota expessially if you work in Residential. I see a good amount of cracked heat exchangers in a heating season and what we do is inform the customer about the possible dangers of the issue. I will turn the gas off to the unit. ( With then watching) I will Put a red tag on the unit with both of our signatures on the tag with a discription of why the tag is There and leave the unit like that . It is  the customers choice at that point to make the decision to fix it or repair it. We don’t disable the unit or anything like that.

I perform a combustion annalasis on the unit to make sure it’s not creating high numbers of CO (anything over 400 is a red tag) anything over 100 we look really close into it and try to bring that number down. it iskind of rate to see a unit with a cracked heat exchanger creating high numbers of CO it is usually a differnt issue.
