Ice cream mix pasteurization failure corrective action

Hello,

We recently had audit & auditor asked us to update our HACCP plan with exact corrective actions for pasteurization failure. I have come up with below. 

If verification shows it is non-conforming, immediately cool down to below 7 degrees & re-pasteurize. 

If re-pasteurization is not possible or cooling exceeds 45 minutes, dispose of the mix.

Non-conforming procedure must be followed.

What is your corrective actions?  I would include something about finding the root cause of the failure BEFORE you try and re-pasteurize

Our previous corrective action was to keep product on hold & follow non conforming product procedure. However, Auditor was not happy with this. As Time is off essence, he asked to describe what exactly we will do. 

We have planned to include above (mentioned in post) corrective action. Thanks for your suggestions, Do you think it should be done in certain time limit if temperature is above certain degrees?
