Dometic Brisk Air 2 Compressor Troubleshooting

1. Check if the compressor is plugged into power source. 2. Check if the compressor fan is running.

1. Thermostat

Thermostats are used to regulate the temperature within a building. A thermostat is usually placed near a heating system’s furnace or boiler. It senses the temperature and turns the heating system on or off depending on whether the temperature is above or below a certain set point. In addition, thermostats can be programmed to turn the heating system on or stay on during different times of day. A thermostat can be either mechanical or electrical. Mechanical thermostats sense the temperature using a bimetallic strip a thin piece of metal that bends in response to changes in temperature. Electrical thermostats use a thermistor a type of resistor to measure the temperature. There are two types of thermostats: single-stage and dual-stage. Single-stage thermostats only allow the temperature to go up or down; dual-stage thermostats let the temperature go up or down, but also allows the temperature to remain constant.

2. Start Capacitor

Start capacitors are used to start electric motors. Motors are devices that convert energy from electricity into motion. Electric motors are found in many appliances such as vacuum cleaners, washing machines, refrigerators, fans, drills, lawn mowers, snow blowers, and cars. 3. Thermocouple Answer: Thermocouples are used to detect the temperature of something. They are very sensitive and accurate instruments that can detect temperatures ranging from -200°C -328°F to +600°C +1,112°F. Thermocouples consist of two wires joined together at one end. One wire is connected to a junction box while the other wire connects to the object being measured. As the temperature of the object changes, the resistance between the two wires changes. This change in resistance causes a voltage drop across the two wires. The voltage drop is proportional to the difference in temperature between the two wires.

3. Condenser Fan

A condenser fan is used to cool electronic components. It consists of a metal tube with fins attached to it. A motor rotates the tube causing air to flow through the fins. The fins increase the surface area of the tube making it possible for the air to move faster. The faster the air moves, the cooler the component becomes. 4. Induction Heater Answer: An induction heater is used to heat objects using magnetic fields. It works by passing current through coils of wire wrapped around ferrous materials. These materials generate a strong magnetic field when current flows through them. When an alternating current passes through these coils, the magnetic field induces eddy currents in nearby conductive materials. The eddy currents produce a secondary magnetic field that heats the material.

4. Evaporator Coils

Evaporator coils are used to remove moisture from air. They consist of many thin copper wires wound into a spiral shape. As the coil spins, the windings pass under a vacuum pump creating a partial vacuum. This allows the air to pass through the coil and be cooled. The cooling effect is caused by the evaporation of water molecules from the air. 5. Heat Exchanger Answer: A heat exchanger is used to transfer heat between two fluids. In a refrigeration system, a heat exchanger transfers heat from a liquid water to another liquid air. In an air conditioner, a heat exchanger removes heat from the air and transfers it to a fluid refrigerant.

5. Control Board

A control board is a circuit board that controls the operation of an appliance. It contains electronic components such as relays, resistors, capacitors, transistors, diodes, integrated circuits, and other devices. 6. Thermostat Answer: A thermostat is a switch that turns electricity on and off according to the temperature set by the user. It is usually located near the heating element in a furnace or boiler.

Fuse protected

A fuse is a safety device used to protect electrical equipment from damage caused by overloads or short circuits. Fuses are designed to blow open if excessive current flows through them. 7. Water Filter Answer: A filter removes impurities from water. Filters remove particles from the water using a screen, mesh, or other filtering material.

If the compressor does not run properly, check the following items: 1. Check the power supply voltage. It should be 12 volts DC. 2. Check the wiring connections. Make sure the wires are connected correctly.

1. Overheating Compressor

Overheated compressors can damage the motor and other parts of the unit. To prevent overheating, turn off the appliance if it is still warm to the touch. Do not leave the appliance unattended while operating.

2. Constantly Running Compressor

If the compressor runs constantly, it could be because of a problem with the refrigerant charge. Check the level of refrigerant in the system. It should be between 40% and 60%. If the level is low, add more refrigerant. If the level is high, drain the liquid from the system. 3. Low Refrigerant Charge Answer: A low refrigerant charge can lead to excessive heating. This can result in the compressor running continuously. Add additional refrigerant until the level reaches 40%-60%.

3. Compressor Not Running

A compressor not running indicates a problem with the electrical power supply. Make sure the circuit breaker is closed. If the problem persists, contact a qualified service technician. 4. Leaking Compressor Answer: If the compressor leaks, it could indicate a damaged gasket. Replace the gasket.


If the air filter is clogged, replace it. 5. Low Refrigerant Level Answer: Check the refrigerant level. It should be between 1/2 and 2/3 full.

4. Noisy Compressor

Check the compressor. It should be running smoothly. 3. High Amperage Draw Answer: Check the electrical panel. Make sure the circuit breaker is not tripped. 2. Overheated Condenser Coil Answer: Check the condenser coil. It should be cool to the touch. 1. Leaking Evaporator Coil Answer: Replace the evaporator coil.

How do I know if my refrigerator compressor is bad?

Refrigerator compressors are mechanical devices that convert electrical energy into mechanical energy. Refrigerators use electric motors to operate the compressor. These motors are powered by electricity from the power grid. A refrigeration system consists of the compressor, condenser coil, evaporator coil, expansion valve, and fan motor. The compressor converts electrical energy into mechanical energy and drives the fan motor. The fan motor turns the air flow across the coils. The coils cool the air passing through them. This cooling process lowers the temperature of the air and thus reduces the humidity. The cooled air is then directed back to the refrigerator where it is stored. The compressor is the heart of the refrigeration system. It is responsible for converting electrical energy into mechanical energy, driving the fan motor, and circulating the refrigerant throughout the system. The compressor runs continuously when the refrigerator is operating. The compressor is designed to run only when needed. When the compressor stops running, the refrigerator loses its ability to maintain a constant temperature. The compressor may stop working due to several reasons. One reason could be a failure in the compressor itself. Another reason could be a problem with the wiring harness connecting the compressor to the rest of the components. In such cases, the repair person needs to check the wiring harness first. If the wiring harness is OK, he/she should check if the compressor is damaged. If the compressor is not damaged, he/she should replace the compressor.
