Tips for Detecting Problems With RV Refrigerator
Finding out that your RV refrigerator is not working can be a very sad moment, especially when you’re out of the road without access to your reseller or repair service. Fortunately, you can often return it back to a working condition with just a few troubleshooting tips. So lets start Tips for Detecting Problems With RV Refrigerator.
How To Diagnose Problems With RV Refrigerator
The first thing to do is to ensure that the unit is level.
Then determine whether it works or completely bad. This can be done by using a thermometer, but in the case of extreme need, you can usually see it by placing a naked hand against the cooling coil inside the main food compartment.
You can also check the rear of the refrigerator to see if the flame is present, if it is in the gas configuration. If there is an electrical configuration, you can place your hand close to the heating element of the rear panel (but do not touch it, as this may cause burns).
Use thermometers intended for use in refrigerators. It is best to use one in each section. The cooling effect of most RV refrigerators comes from the freezer and then goes to the main compartment so if the freezer is good but not the main compartment is likely to reduce the airflow.
The vaporizer fan, which is the fan in the freezer initiates chilled air from the freezer to the food compartments through a tube called diffuser control. The diffuser is located in the upper part of the food compartment. Pay attention to the evaporator fan in the refrigerator. Also check the diffuser channel to see if it is blocked by ice. Evaporator fans turns on and turns off, so if you do not hear, wait a moment. The fan is turned off in most refrigerators when you open the door, so pay attention.
If you notice no sign of cooling, scent around the refrigerator. Most RV refrigerators, utilize water, liquid ammonia, gaseous hydrogen and sodium chromate in cooling coils for heat transfer. If there is an ammonia odor, then the heat transfer coil have leaked out and will require a repair or a professional replacement. At this time, contact RV Dealer to determine which option will be the best. Also, make sure the device is still under warranty.
You can cope with many other problems; Therefore, if you do not smell the ammonia, continue with solving the problem by following these steps. Try using the refrigerator in all working modes. If the unit is running on a LP gas, but not on power, or vice versa, this means that the basic cooling unit is in perfect condition.
Use The Meter To Check The Refrigerator Voltage.
For maximum capacity, the VD cooler type of filter usually requires 120 volts AC, 12 volts DC and LP gas source. Gas is a predominant source of heat for coil cooling, while 120 volts is an alternative source, which is commonly used when connected to shore power in the campground. 12 volts DC are used to control the circuit and, in some cases, to heat the coil.
If they operate on liquefied petroleum gas, but not up to 120 volts of AC, check the 120 VAC at the rear of the refrigerator. First, check the switches and fuses on the board, then check the voltage on the power outlet on the rear of the refrigerator. A multi meter is recommended, but if you connect a dryer or other device to the socket, you can know if there is tension.
A 120 V AC at the outlet that supplies power to the refrigerator. Also check if there is a DC 12 volt in the rear of the refrigerator. This can be done using a 12 V test or multi-meter. If both voltages are present and all LED’s are working, check the error codes on the refrigerator that has this function. This can quickly take you to the problem area. Codes and the process of reading them should be in the owner’s brochure, but if this is not available, you can find information on the site of the refrigerator manufacturer.
Most refrigerators are also connected, for 120 volts.
Check the circuit breakers if there is no current. To test an electric heater of 120 volts AC, a multi-meter must be used. Be careful because the voltage is dangerous. To do this, wear rubber gloves under dry conditions. If you are not sure of your electrical skills, let it be done by a professional.
Cables that supply power to the heater element usually come from a metal enclosure underneath the cooling unit, available from the rear of the heater. Generally, only minor removal of protected parts is needed to gain access. This must be done while the device is turned off. Test the voltage while the heater is switched on. If the voltage is detected in one cable, but not the other, the element may ignite. If there is no voltage in the element, the problem might be wiring the radiator panel or plate. This may require a qualified RV store.
If there is no 12 Volt DV current in your refrigerator, make sure the batteries are charged, then check the fuses and switches.
Three-way refrigerators can work with 12 volts DC because they have an additional electric heating element. Test the voltage on the heating element in the same way as the 120 V supply units, but use a low voltage DC mode (usually 20) on the meter.
If the unit operates at 120 V, but not LP Gas, try to determine if there is a good flame. First, make sure the LP container is sufficiently gas-tight, that the valve is switched on and that no safety devices, such as LP alarms is not disconnected from the power supply. Then activate the controls for using the gas burner. If switched on but later switched off quickly, the thermocouple (which detects flame heat and controls the gas valve) may be defective. Often it is bad, and it’s good to take one with you on a trip. The thermocouple is connected to the main gas valve on the rear of the refrigerator. It has a pipe extending to a gas burner. Generally, it cam be replaced by owners with DIY skills.
If the flame does not fire, pull the burner area out of the burner port. Most times rust and other particles fall from the valve and block the burner unit. To solve this problem, remove the metal shield and use a cleaner to clean near the burner. If necessary, insert a thin wire into the burner holes to unclog it. If the flame goes on, look for the flame quality; requires a well-formed flame, mostly blue.
If The Ice Maker Does Not Work, Make Sure That The Water Valve Is Open.
Sometimes the cooling unit is filled with the required mixture of ammonia, but it still does not work. If it seems that the refrigeration unit needs to be replaced, consider removing the entire refrigerator and put it face down for a week or two. Sometimes this helps to get it working again, and all it need is a little work and time. You don’t have anything to lose.
Refurbished Circuit boards and refrigeration devices are available for different RV refrigerators. If they have a warranty from an accredited supplier, it will allow you back to the road with huge savings.
Many times, a little issue can makes your refrigerator to stop functioning as it should. By checking the above items, it is possible to avoid an expensive cost for refrigerator repair. In other cases, you can as well give a description to the technician about the problem, for this will help to make an informed decision on repairs.
