The undercounter unit in the island had been running without stopping and the surrounding cabinetry was warm. The front vent path was packed with dust and pet hair, and he cleared the whole route.

Undercounter refrigeration
Sub-Zero Drawers Cool but Not Cold
Refrigerator drawers, beverage centres and undercounter freezers built into islands, butler's pantries and lanai kitchens — small boxes in tight, hot cabinets.
An undercounter unit lives inside a sealed cabinet. Most of what goes wrong with one is a heat problem before it is a part problem.
Symptoms
What people describe
- The drawers feel cool but nothing inside is properly cold
- The unit is icing up along the top of the drawer opening
- It runs constantly and the cabinet around it feels warm
- A drawer no longer glides and will not sit closed
- The outdoor unit on the lanai stopped cooling in July
- There is water standing in the bottom of the compartment
Detail
How the job goes
Undercounter refrigeration is the equipment that never gets thought about until it stops. A pair of refrigerator drawers in the island, a beverage centre in the butler’s pantry, a compact freezer under the bar, an outdoor-rated unit built into the summer kitchen. Each is a complete refrigeration system compressed into a space the width of a base cabinet, and that compression is the source of most of the faults we are called out for.
Heat is the first suspect
A full-height built-in has a large condenser and a clear path for its air. An undercounter unit has neither. It sits inside a cabinet run, often with granite above it, cabinetry on both sides and a toe kick in front, and it depends entirely on the clearance the installer left and the grille staying open.
On Fleming Island the practical version of that problem is seasonal. The unit copes from November to April and starts falling behind in June, when the kitchen itself is warmer and the compressor has less temperature difference to work with. The owner describes it as the unit slowly getting worse. What has actually happened is that a marginal air path stopped being adequate.
We check the grille, the condenser, the clearance above and behind the cabinet, and whether anything has been stored against the exhaust. It is unglamorous and it resolves a real share of these calls without a part.
Drawers are mechanical as well as refrigerated
A drawer model has to seal on all four sides while sliding in and out several times a day. The runners take the abuse, the gasket takes the abuse, and the two faults look similar from the outside. A drawer that has dropped slightly on its runners will stop compressing its seal along the top edge, and warm room air follows the gap. In a humid house that produces a distinctive band of frost along the inside of the opening, and eventually water in the bottom of the compartment when it melts.
That is repairable. Runners, rollers and gaskets are ordinary parts. What we want to avoid is a compressor being blamed for what is really a drawer that no longer closes squarely.
Outdoor and lanai installations
Plenty of houses along Doctors Lake have a covered outdoor kitchen with refrigeration in it. Two things matter there. The first is whether the unit is an outdoor-rated model — an indoor unit installed outside will run hard, sweat and fail early, and there is no repair for that beyond replacing it with the right equipment. The second is ambient temperature. Even a properly rated unit has an upper limit, and a west-facing lanai in August will find it.
We are honest about which of those we are looking at. If the answer is that the appliance is doing everything it can in the conditions it has been given, you should hear that rather than pay for a part that will not change anything.
Small boxes, real sealed systems
An undercounter unit still has a compressor, a condenser, an evaporator and a charge of refrigerant, and sealed-system work on one is the same discipline as on a full-height unit. Our technicians hold EPA Section 608 certification for refrigerant handling. On a compact unit, though, the economics deserve a sentence in the estimate: the cost of sealed-system repair against the value and age of the appliance is a real conversation, and we would rather have it before the work than after.
Access before anything else
An undercounter appliance is usually easier to reach than a built-in, but not always. Units set into a stone island with an undermount sink above them, or into a cabinet run that was scribed to the floor, sometimes cannot come out without the counter being supported. We look at that first and tell you what is involved before anything is disconnected.
The visit is a flat diagnostic fee, credited toward the repair. You get a written estimate first, genuine OEM parts, 90 days on labour and 365 days on parts.
Price bands
What does undercounter and drawers work cost?
These are the bands this kind of fault lands in once it is diagnosed, parts and labour together. The visit comes off whichever line the job turns out to be.
| Work | Typical range |
|---|---|
| $80 diagnostic visit | $80 |
| Evaporator or condenser fan motor | $250–$600 |
| Ice maker, water valve or supply line | $250–$620 |
| Door gasket or seal replacement | $250–$650 |
| Defrost heater, thermostat or sensor | $260–$630 |
Ranges, not quotes: the firm figure is written down after the diagnosis and nothing is ordered or billed until you have approved it. On this page the work we describe runs from $80 for the visit to about $650 at the top of the band above. The whole book of bands is on the pricing page.

Asked and answered
Questions about undercounter and drawers
- Why does an undercounter unit in an island struggle in summer?
- Because it has to push its heat out into a sealed box of cabinetry. These units draw and return air through a narrow front path, and once that path silts up with dust and pet hair the compartment cannot hold. Most of what goes wrong with one is a heat problem before it is a part problem.
- Is a drawer unit on a covered lanai repairable?
- Usually, but the ambient it sits in is part of the story. A cabinet rated for a conditioned kitchen will run hard and cut out in a hot, humid space, and repairing the fan will not change the room. We will repair it and tell you plainly what to expect from it out there.
- What does undercounter work cost?
- A condenser or evaporator fan motor runs $250–$600, a drain, valve or supply line fault $250–$620, a door seal $250–$650. Clearing a blocked front air path is often part of the diagnostic visit rather than a separate charge, and the $80 comes off whatever the repair turns out to be.
Terms
Before you book
A flat $80 covers the visit and the diagnosis. It is credited toward the repair if you go ahead with the work.
Labour is warranted for 90 days and parts for 365 days from the date of the repair. Genuine OEM parts throughout.
We service Sub-Zero refrigeration only, as an independent shop. We do not service heating or air conditioning. No furnaces, no heat pumps, no air handlers, no mini-splits and no ductwork. That is a separate trade with its own licensing, and a call about a house that will not cool belongs with an HVAC contractor rather than with us.

Water was collecting under the unit and had started to lift the floor edge. The condensate pan had split and the drain had been rerouted badly by somebody before us. Both put right in one call.

The drawers in our island were cool rather than cold. He took the front off, cleared an air path packed solid with dust, and measured the compartment again an hour later before calling it done.
