Tempering Question

I was tempering 4 D2 blades today 450 degrees for 2 hrs. I got tied up on business and let it run over the 2 hrs. When I got back the oven had cooled down to 375 degrees. I am not sure what to do, any help would be greatly appreciated. Start heat treat over, retemper or what????
Thanks in advance.

Did you set the oven to only run for 2 hours? If that's the case and it was just in the cool down faze you're ok. If the oven just shut down, put them in for another cycle the blades will be fine.
