Dixie Narco 5591 bottle drop drip pan overflow

[Cashflow KD]

I have a DN5591 bottle drop over flowing with water in the drip pan. Checked the seal around the door, swapped out delivery bins, added a timer, sponges, and turned down thermostat And it’s still overflowing every couple days.

Any help/suggestions would be really appreciated.

Is it inside a climate control room or outside in a warehouse?   If it’s inside i would replace the thermostat.

A new thermostat won't help with condensation overflow.  It's almost always due to excess moisture in the air around the machine.  This can get into the machine around the recovery unit, through unplugged holes in the side of the cabinet where the harnesses go through or a loose door gasket.  This one really sounds like it's in a humid environment.

The machine is located inside an air conditioned senior home cafeteria next to the kitchen.

 Seems like you're building a little ice that's being defrosted and ends up in the pan.   

Either hot, moist air is getting into the cold cabinet,

you have a slow evap fan or

freon is a little low.

There actually was a bit of ice build up on the evaporator thats on the E tray side. Once I added the timer it did go away. 
I’ll check about the evap fan.

And would it still need Freon even if drinks are cold enough?

[Vendo Mike]

Slightly low freon will still cool the case until ice builds up enough to slow airflow over the evap coil.  Eventually, enough ice will build up until there is no airflow and the unit reads 80F.  I would focus on airflow and sealing the cabinet to start with.

It's a bit of a "snowball effect" forgive the pun.
