    So I am looking for suggestions as I have run out of ideas and the techs doing the warranty work on this unit cant figure it out either. here we have an Alto Shaam CTC20-20G. It has had issues from the day it got installed. the door keeps leaking steam out of it and nothing we have done or do fixes it. I’ve looked at everything and the techs that come out for the warranty work have done everything they can and no one can figure it out. this machine is only 10 months old. all the diagnostic testing has been done almost every part on the door has been replaced. the hinges have even been adjusted. its already ruined 1 door seal. Any suggestions that maybe we have over looked?

    Check the venting of the oven. If there is no place for pressure to go steam will take the least resistance/weakest path.

    thank you for that suggestion the venting system is working great it has been tested too. any other ideas? I think it is an issue with the door some how but cant figure it out. any ideas about what could be? the door is straight and no bending in the door or the glass.

      Check that the oven itself is level and properly mounted on the base. Equally supported on all 4 feet. Over time and with the weight of load it may be distorting the oven frame when heat is added. I’ve had freezer cases crack from not being bedded correctly. If you have access to a precision level, check that all 4 frame items are square and level. You never know what happened to the oven during shipping till you check it.

      What hinges and latch does it use? They used to use Kysor refrigeration hardware. But this looks like a gas combi-oven

        it is level and no cracks i have been over this with a fine tooth comb it is the CTC20-20G latches have been changed 3 times now hinges are adjustable but I am wondering if maybe one is bent on the inside where I cant see and that is causing the issue. even a millimeter of a bend I can see affecting it. this is a combi.

    Do you know if the tech checked pressure to make sure it is not overshooting its rated psi? Have they checked the drain? ill have to look at a breakdown to verify but I am assuming there is a solenoid or something that allows condensation to drain. i would check that on any steamer with a leak at the door.

      I didn’t realize that you had a cart for loading and unloading the oven. So operator usage also comes into question. Banging, hitting and hanging during operation can be tough on doors. But depending on what version (build date) there was a service hinge for the bottom door. I know that all combi’s have problems with the condenser drain systems. The cold water in the condenser box is what keeps the steam pressure under control.
