Older Convection ovens

Toast

HI,

I'm new to the forum but stumbled on it looking for some help for a bit of trouble I've been having.

I have been baking for farmers market for about 3 years out of home and recently rented a commercial space that is already outfitted. The problem I've been having is with the oven. Its a older Blodgett cabinet convection oven and the convection does not turn off. I can't get a good oven spring because the oven is so dry. Does anyone have any advice?

 

the search box in the upper right corner has tons of articled on steaming.  the best results I have ever had is a metal pan in the bottom filled with a cotton towel (old bath towel) and covered in boiling water before placing on bottom of the oven.  remove after 10 minutes.

Cheers,

Nick
