Service your boats refrigerator regularly to avoid any problems.

There are a couple of ways in which your isotherm refrigerator can start giving you problems if it is not properly serviced. Fortunately, there is an easy way to go about maintaining a well-functioning refrigerator, which will be handy even for the less than technically inclined marine refrigerator owner. Isotherm refrigerator troubleshooting and maintenance requires the identification of the most common reasons for refrigerator troubles, using a process of elimination in order to narrow down possibilities. With simple tests, the cause of malfunction can be identified and subsequently restore the unit its usual working conditions.

Reduced temperature control

When sailing in the warmer climates, a common concern with refrigeration is that the unit will not provide adequate cooling. Proactive measures include ensuring that there is plenty of ventilation around your fridge. Ventilation is the important for getting the best functioning from your refrigerator because if the temperatures rise too high, the condenser will not function as it should.

Where weather conditions are extremely high, supplementary cooling systems can be installed to assist the fridge to work optimally by bringing the heat down. If the problem persists, make sure that your refrigerator is not positioned in direct sunlight. The unit’s doors need to be able to close properly to retain the cold properly.

Temperature gauges are subject to get bumped and adjusted by accident. If your refrigerator stops cooling efficiently, check that the gauge has not been disturbed and that you have not overfilled your fridge.

Refrigerator electrical failure

Electrical components in a refrigerator can fail after some time of operation. The replacement of isotherm fridge parts is easy and can be performed in person or by a professional. Loose or broken wires and connectors may disturb the power supply of your unit. This is one of the commonly experienced challenges and a test to rule this out requires an assessment of the electrical component.

When the refrigerator has been removed into an open space, assess the back of the unit to see if you can spot loose wired or damage. Using a voltage metre, you can assess unseen damage by checking if there is any power coming into the unit from the power source. If the wiring is bad or damaged, the readings will be lower than the set out levels specified in the owner’s manual.

Leaks in the refrigerator

Your refrigerator may start to leak, which can also signal any number of problems. Water can visibly start to collect on the inside of the fridge. This can signal that the drainage tubes of the fridge have an obstruction. Running some water with cleaning solution through the tube can assist to dislodge the blockage in the drain. Water can also collect on the outside of the fridge in the water tray. Often nothing more than a signal of a dirty water pan, the water tray should be cleaned regularly as part of a maintenance routine to ensure that the water can evaporate and does not create worry around a leaking fridge.

Refrigerator running too long

Running a fridge in a dusty environment can cause it to run for extended periods of time. Optimally functioning refrigerators will work at various intervals as the refrigerators reach their ideal temperature. If you experience the challenge of a unit that is constantly running, you may need to clean the surrounding area to clear excess dust. This dust can clog vents and collect on condenser coils making them less effective at cooling. Taking a brush and a vacuum cleaner to the unit will go a long way to removing the build-up of debris.

Another common cause of prolonged runtime is a low temperature setting on the refrigerator. This will cause the refrigerator to work harder to keep the temperature down. Adjust the thermostat to the desired temperature to solve this issue.

Ongoing or one-off servicing

Marine refrigerators are a must have on-board if you intend to spend long hours on there.

Regardless of how you use your boat, a refrigerator on board can be handy. If you are the owner of a smaller vessel, you don’t have to worry about a fridge that takes up too much space. You can simply customise the unit to fit into the space you have, efficiently. There are many variations of marine refrigeration systems are available on the market. The all have different advantages and disadvantages and the selection of the perfect refrigerator for you will depend on the size of your boat and how you use it.

Isotherm Refrigerator

The first type is the isotherm refrigerator, which is compact in size and can open either at the top or the front. This is the most preferred cooler system for you especially if you have enough room to fit it on-board. Isotherm units fits neatly in the cabinet systems where you will have made space for it. Connectable with just a couple of wires, this unit is purchased pre-insulated and does not require additional insulation. This unit provides excellent cooling and is able to achieve cool temperatures very quickly.

Holding Plate

The holding plate is another type of refrigerator system, which gets its name due to its ability to retain cold temperatures for protracted periods at a time. The thick plates are cast from aluminium or stainless steel they comprise internal tube systems which consist of cooling refrigerant. This type of cooler also attains temperatures very quickly. Comparable to a block of ice, the trick of the holding plates is in the ability of the refrigerant to freeze, thereafter staying cold for long periods at a time.

The disadvantage of holding plates is that they use large amounts of power to stay cool, in comparison to isotherm refrigerators. On the other hand, cooling only needs to take place once a day as the plates retain temperatures for hours. The plates can be cooled while running the generator or engine. The holding plates also require additional insulation.

Portable Ice Chests

Portable ice chests are an option for people who do not spend too much time on-board their boats. Just as its name suggests, this refrigeration system is mobile and can be transported to and from the boat. A simple solution if you do not have too much money to spend on refrigeration too.

Built-in ice boxes are a variation of the ice chest save the face that it stays fixed on the boat. This inexpensive option is also great because it does not use up energy and there is no need to power it up. They hold up well against the competition, with top of the range models being capable to keep ice in its frozen state for longer than four days.

The functioning of a refrigerator depends largely on the availability of space and power. These are the two key factors to consider in selecting the unit for you. Powered units tend to use up large amounts of energy and if you intend to operate on battery power, consider how much capacity your battery can handle, in conjunction with all your other devices that may need power.

With all this in mind, you are ready to make an informed buying decision.
