Fermenting fridge advice

[colgilbec]

Hopefully its in the right section , just set up a fermenting fridge using an inkbird ,coupled to a heat belt for heating and fridge kicks in when required.
I didnt have to do any drilling etc as the cables for brewbelt and temp control went through the drain cap quite nicely
Fermenting away nicely , but one thing has just dawned on me ,hope its not a stupid question does there need to be an air vent ?.
As will the pressure within the fridge build up?, i suppose in a worst case scenario it would blow the front door open? [please no Michael Caine puns,lol]
Thanks in advance for any replies.

Unless you've blocked the drain completely any excess pressure would go that way.
Like you say high pressure would help open the door, crash cooling and low pressure may be more interesting.

Thanks keith i was guessing that but just needed reassurance as i cannot see anything related.

Never had any kind of problem with pressure inside a fermenting fridge. As Kieth says, there's already a vent in most (all?) fridges for the drain at the back, as long as you don't block it.

Fridges simply aren't that leak proof so nothing to worry about

Thanks Jim and Meatymc for verifying.
