Bosch Refrigerator dF Means the Freezer Drawer Reads as Open

What dF means

The freezer twin of the door alarm is dF. According to the repair manual it is a defective F-door switch, set when the control senses that door open for more than one hour. With a bottom-freezer layout the usual cause is a drawer that never got pushed all the way shut, and not a broken part, although a worn switch gives the same code.

Common causes of dF

Drawer held open by food or packaging jamming the runners
Freezer door switch that has stopped working or sticks
Worn runners that stop the drawer from seating

✓ One safe check you can try

1. Pull the freezer drawer fully out. 2. Check the runners and basket for a bag or box that slid behind and blocks the drawer. 3. Push it firmly closed and confirm the gasket touches around the whole edge. If dF returns with the drawer shut, we need to test the switch.

! Why to stop there

Forcing a jammed drawer can snap the runners or crack the front panel.
Frost builds quickly if the drawer sits slightly open, creating a new problem.
A worn runner and a failed switch look alike from outside, and only one of them is a quick fix.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

dFdF questions

Why does my freezer drawer keep setting off dF?

Usually something is preventing it from closing fully. Even a small gap is enough for the control to treat the drawer as open once an hour passes.

Could I lose my frozen food?

If the drawer stayed open for several hours, yes, that can happen. Check that everything is still frozen hard before you refreeze or cook it.

What if the drawer closes but the code stays?

Then the switch or the runners are the likely cause. We test both and give you a written price before any repair. It is worth knowing which one before paying for a part.
