Just completed our initial checkout of our new KZ Spree 263 RKS on a two day campout. I have been going through all the manuals and was specifically looking for location of the fridge moisture reduction heater switch. The manual for this N811 F mentions the heater but nothing about a switch to disable it like our previous Norcold on our 2007 Spree. Anyone know how to disable the heater to reduce power consumption? Also this fridge appears to have the optional fan that I can hear come on periodically. The schematic shows a temp switch in series so I am assuming this operates when the outside temp goes above a certain set point.

Norcold did away with on/off switch for the door flap heater.But heater only operates when fridge is ON :SFan is controlled by snap-disc t-stat attached to condenser fin and closes/opens based on condenser fin temp ---not ambient air temps

If the OP's Norcold likewise lacks a switch I'd imagine the same mod could be done with it as well.
