Dometic DMC4101 / DMC4081 Freezer Cold, Fridge Warm
FRIDGE WARM
Dometic DMC4101 / DMC4081 Freezer Cold, Fridge Warm
The freezer is cold but the fresh food section sits in the 40s or 50s. These fridges have one cooling system in the freezer: a fan blows cold air from the freezer down into the fridge section. Anything that stops that air flow leaves the freezer cold and the fridge warm.
Before you start
- You’ll need a fridge thermometer and a screwdriver.
- Good reading Middle snowflake blinking (freezer fan fault).
Fits these models
Dometic 12V DC compressor refrigerators: DMC4101 (10 cu ft) and DMC4081 (8 cu ft), left or right hinge, every finish.
What you’ll see
Panel normal, freezer cold, fridge warm
STEP 1
Check the panel
Look at the temperature lights.
Is the middle (level 3) snowflake blinking?
Freezer fan fault
Follow the middle snowflake blinking guide.
STEP 2
Check the air control in the freezer
Owners report an air control slider inside the freezer that isn’t described in the manual. Set toward Max, it keeps more cold air in the freezer and can leave the fridge section warm.
Is the slider set to Max?
Move it toward Min
Slide it toward Min and check the fridge temperature after a few hours.
STEP 3
Check for blocked air vents
Dometic’s manual lists blocked air vents in the fresh food compartment as a cause. Make sure food isn’t pressed against the vent openings in either compartment.
Were the vents blocked?
Clear them
Leave space around the vents and recheck after a few hours.
STEP 4
Check for ice and the fan
Ice in the freezer’s rear panel or around the fan blocks the air path. Owners have found the freezer fan iced in or rubbing its foam housing.
Is there ice behind the rear panel, or is the fan slow or stopped?
Clear the ice or replace the fan
Let it thaw, find out why moisture got in (door seal, drain) and see the freezer fan guide.
