The short answer
A Broich drawer unit that is too warm is usually starved of air at the front grille or blanketed in dust on the condenser behind it. Clean both first. Drawer gaskets and overfilling come next, and the compressor and sealed system are last and are not owner work.
What you observe
- Both drawers warm and the compressor always running — Heat cannot leave the cabinet through the grille.
- The grille and the cabinetry around it feel hot — A unit recirculating its own hot air.
- One drawer warm and the other acceptable — A gasket or an overfilled drawer rather than a system fault.
- Warm after a kitchen refit — Cabinetry or flooring now blocking the grille.
- NEAR MISS - warm for a day after being filled — An undercounter unit takes time to recover.
Causes, most likely first on this brand
- A blocked or restricted front grille — First and foremost on any built-in unit. A grille packed with dust, or covered by new flooring or a plinth fitted flush after a refit, leaves the condenser breathing its own exhaust.
- A condenser blanketed with dust — Second. Behind the grille the fins collect everything that passes at floor level, and once matted the unit cannot shed heat however hard the compressor works.
- A drawer gasket that is not sealing — Third. Each drawer seals on all four sides, so a crumb, a hardened corner or a package caught in the path leaves a gap the drawer cannot close out.
- Drawers overfilled or air paths blocked — Fourth. These units move air around the contents, and a drawer packed to the vents starves the part of the cabinet furthest from them.
- A fan, thermostat or sealed-system fault — Last. Suspect it only once the grille, the condenser and the gaskets have all been ruled out.
Check in this order, and why
- Look at the front grille and feel the air — Hot air with nowhere to go is the answer most of the time.
- Remove the grille and inspect the condenser — Matted fins are visible immediately and free to fix.
- Close each drawer on a slip of paper — It should drag on all four sides of each drawer.
- Check nothing was fitted over the grille in a refit — Flooring and plinths are a common late cause.
What an owner can safely check
- Remove the front grille and clean it — Vacuum it and wash it if it is greasy, then refit it the right way round.
Tools: vacuum, clothAbout 20 min
- Clean the condenser fins and the fan — Vacuum gently along the fins; do not bend them with a brush.
Tools: vacuum, soft brushAbout 30 min
- Clean and test each drawer gasket — Wash the seal and check the paper drag on all four sides of both drawers.
Tools: cloth, paperAbout 25 min
- Re-load the drawers with air gaps — Keep contents clear of the vents and do not pack to the back.
About 15 min
- STOP HERE if a clean, ventilated unit still will not cool — That is fan, thermostat or sealed system.
Before you open anything
Safety
Switch the unit off at its breaker before removing the grille or cleaning the condenser, because the fan can start at any time while it has power. Condenser fins are sharp - wear gloves. Never run the unit with the grille off or with the opening blocked to make cleaning easier, and move food to a cool box while you work, discarding anything that has been above a safe fridge temperature for hours.
When to call a technician
Call when the grille and the condenser are clean, the gaskets drag on paper all round and the unit still will not hold temperature - especially if the compressor runs constantly or not at all. Call sooner if the cabinetry around the unit is hot, because a built-in unit that cannot breathe damages itself and the carcass around it. Mention that it is integrated when you book.

What this page does not cover
This page covers the Broich panel-ready undercounter refrigerator drawers, which are built into cabinetry and breathe through a front grille. Freestanding cabinets with rear coils reject heat differently and are a different page. Not covered by design: thermostat settings, temperature figures beyond safe-storage guidance, part identifiers and cut-out dimensions.
