The short answer
Frost in a Broich drawer means humid air is getting in, and the gasket is the first place to look. A freezer drawer that will not set is usually the same fault plus a restricted front grille. Clear both before touching the control. There is no ice maker here, so no valve or supply line is involved.
What you observe
- Frost around one edge of a drawer — The gasket is open along that edge and nowhere else.
- A freezer drawer that will not set ice trays — The compartment cannot hold below freezing.
- Frost over the vents inside the compartment — Airflow is being blocked as well as air getting in.
- Both drawers frosting at once — A ventilation or capacity problem rather than one gasket.
- NEAR MISS - light frost after a long door-open period — Normal, and it should clear itself.
Causes, most likely first on this brand
- A drawer gasket not sealing on all four sides — First on this design. The seal runs right round the drawer, and one crumb, one hardened corner or one package in the path lets a steady stream of humid room air in, which becomes frost at the coldest surface.
- A restricted front grille or dusty condenser — Second. A unit that cannot shed heat has no spare capacity, and the freezer drawer is always the first compartment to show it because it has the least margin.
- A drawer overfilled or blocking the vents — Third. Packing to the vents stops the cold circulating, so frost concentrates near the outlet while the far end of the drawer stays too warm.
- A drawer panel out of alignment — Fourth. A heavy custom front that has dropped holds the drawer a fraction proud of its seal, which produces exactly the same frost as a dirty gasket.
- A defrost, sensor or sealed-system fault — Last. Worth suspecting only after gasket, grille and loading have all been cleared.
Check in this order, and why
- Note where the frost forms — Frost marks the gap. One edge means one gasket section.
- Close the drawer on a slip of paper at several points — It should drag on all four sides.
- Remove the front grille and check the condenser — No spare capacity shows in the freezer drawer first.
- Look along the drawer front for a dropped panel — A panel out of line holds the drawer off its seal.
What an owner can safely check
- Empty the compartment and clear the frost — Switch off and let it melt rather than chipping it away.
Tools: towels, cool boxAbout 120 min
- Clean the gasket and test it all round — Wash the seal, dry it, and check the paper drag on all four sides.
Tools: cloth, paperAbout 25 min
- Clean the front grille and the condenser — Vacuum both; the freezer drawer feels a restriction before anything else does.
Tools: vacuum, soft brushAbout 30 min
- Re-load with the vents clear — Keep contents away from the outlets and do not pack to the back.
About 15 min
- STOP HERE if a clean, sealed, ventilated unit still frosts — That is defrost, sensor or sealed system.
Before you open anything
Safety
Switch the unit off at its breaker before clearing frost or removing the grille, since the fan can start at any time while it has power. Never chip ice off an interior surface with a knife or a screwdriver, because the cooling circuit can run directly behind it. Condenser fins are sharp - wear gloves. Move frozen food to a cool box, and discard anything that has thawed rather than refreezing it.
When to call a technician
Call when the gasket drags on paper all the way round, the grille and condenser are clean, the compartment is loaded with clear vents and frost still returns or the freezer drawer still will not set. Frost that rebuilds quickly after a proper clear-out points at the defrost system or a drawer alignment that needs adjusting, and both are worth saying when you book.

What this page does not cover
This page covers frost and freezing faults in the Broich panel-ready undercounter drawers, which seal on four sides and take trays rather than a plumbed ice maker. Cabinets with automatic ice makers fail at valves and lines instead. Also absent: control settings, storage times, part identifiers and drawer capacities.
