A coil that looks grey rather than clean is not shedding heat, and in August that is the difference between an appliance that keeps up and one that does not. ### A third of this catalog lives outside Twenty-six of U-Line’s seventy-six US models are outdoor units, and several more are marine. These appliances are built for it — but built for it with maintenance, and the service interval that works for a kitchen unit does not work for one on a terrace three blocks from the water. ### Salt is the difference, not heat Heat is a load an outdoor unit is designed for. Salt is the thing that changes the appliance: it holds moisture against metal, it takes the condenser’s ability to shed heat away gradually, and it corrodes fixings and door hardware so that a straightforward repair becomes twice the job. Nearly everything on this page comes back to how close to the water the appliance is. A condenser that cannot shed heat The first answer, and outdoors it arrives faster. The service interval that works in a kitchen does not work on a terrace. Ambient beyond what it was set up for The manual names excessive ambient temperature and direct sunlight. A unit in afternoon sun with no shade is being asked for more than it can give. A seal working harder than any indoor seal Humidity is the load out here. A marginal seal that would pass in a kitchen will not pass on a terrace. Corrosion on the parts that hold it together Fixings, brackets and door furniture. It rarely stops the appliance and it frequently makes the repair twice the job. Look at the condenser coil Grey rather than clean means it is not shedding heat, and outdoors that happens much faster than in a kitchen. Check what shade it has The manual names direct sunlight and excessive ambient temperature outright. An appliance in afternoon sun is being asked for more than it can give. Feel the air leaving the grille It should be warm and moving. Nothing moving is a condenser fan or a blocked grille. Check the fixings and the door furniture Salt corrodes the things that hold the appliance together before it stops the refrigeration.

Nearly everything on this page comes back to how close to the water the appliance is. ### It was fine last summer. A year of salt is a measurable amount on a condenser. Outdoor units degrade gradually and then miss a summer, which is why they are worth servicing on a schedule rather than on a complaint. ### Should I cover it in the off season? Only with something that breathes. A sealed cover on an outdoor appliance in this climate traps humidity against it, which is worse than the weather it was keeping out. --- **[Read full article: An outdoor unit struggling in summer](https://ulinemiami.support/symptoms/outdoor-unit-struggling-in-summer/)**
