  • Power supply to the fridge controls the heat input level to the fridge, and thus, its cooling temperature.
  • The fridge doesn’t have any moving internal parts.

Components That Make Up The Refrigerator

Dometic refrigerator rm 1350 comprises several components that work together to achieve its cooling effect. Understanding these components, their functions, and how they interact with each other can help you troubleshoot the fridge when it fails.

  • Heat source – provides the required heat to the fridge, usually a propane flame or an electric heating element.
  • Evaporator – transfers heat from inside the fridge to the cooling medium.
  • Absorber – absorbs the ammonia vapor and mixes it with hydrogen gas to create ammonia-hydrogen gas.
  • Condenser – releases the heat from the ammonia-hydrogen mixture into the surrounding environment.
  • Thermostat – senses the fridge’s internal temperature and shuts off the fridge when the temperature reaches the set level.
  • Cooling tower – facilitates the circulation of hydrogen gas within the fridge.
  • Heat exchanger – transfers heat from the ammonia-hydrogen mixture to the condenser.

Understanding dometic refrigerator rm 1350’s general overview, how it works, and its components is crucial for any rver. It enables them to troubleshoot the fridge when it malfunctions, ensuring that it operates efficiently. In the next section, we will discuss the common issues that rvers face when using dometic refrigerator rm 1350 and how to troubleshoot them.

Common Problems And Solutions

Every rv owner knows that a reliable refrigerator is essential when traveling on the road. The dometic rm 1350 is the go-to fridge for rv enthusiasts who want to keep their food and drinks fresh while on the go. However, like with any appliance, it is not uncommon for problems to arise.

In this section, we will tackle the common issues that you may encounter with your dometic rm 1350 refrigerator along with their corresponding solutions.

Common Error Codes And What They Mean

Faulty error codes on dometic rm 1350 refrigerators can cause a great deal of inconvenience.

  • er1 – this error code means that the thermistor is defective or open and must be replaced.
  • er2 – the communication link between the display board and the main control board is broken. Repair or replacement of the affected component is required.
  • er3 – the eeprom memory is corrupted, triggering this error code. A motherboard replacement may be necessary.
  • er5 – the temperature sensors have failed. It is advisable to replace the sensors if the problem persists.

The Refrigerator Not Cooling

A cooling issue in your rv refrigerator can significantly disrupt your travel plans, and it may be due to the following causes:

  • dirty condenser coils – dust and debris can accumulate on the condenser coils over time, reducing the refrigerator’s ability to cool correctly. Clean the coils with a vacuum or a brush.
  • inadequate airflow – ensure that your refrigerator has at least a 1-inch space around it to allow for proper ventilation. Also, check the inside of the unit, making sure that the fans are working correctly.
  • faulty door seal – a worn-out or damaged door seal can cause heat to enter the refrigerator, leading to cooling issues. Make sure the seal is in good condition by checking for leaks and replacing it as necessary.

The Refrigerator Not Defrosting

If your dometic rm 1350 refrigerator is struggling to defrost, it may be indicative of one of the following issues:

  • frost build up – if the evaporator coils are covered in frost, defrost the refrigerator manually. To do this, turn off the unit and let it thaw, then turn it back on.
  • damaged defrost timer – if the defrost timer stops working, frost will begin to accumulate in the unit. Replace the defrost timer if you suspect it is faulty.
  • defective defrost thermostat – the defrost thermostat is responsible for turning off the defrost cycle once it completes. Replace this component if it fails.

The Fridge Not Turning On

When your fridge won’t turn on, it can be incredibly frustrating.

  • dead batteries – if you’re using a 12v refrigerator, check that the rv’s batteries are not drained and that the correct wires are connected. Replace the batteries if needed.
  • tripped fuse – look for any blown fuses in the rv’s fuse box and replace them with the correct rating to avoid overloading the system.
  • faulty thermostat – a malfunctioning thermostat can prevent the refrigerator from turning on. Check to ensure that the thermostat is set correctly and replace it if faulty.

The Refrigerator Runs Too Much

Fridges that run continuously are problematic for both power consumption and wear and tear on the appliance.

  • dirty condenser coils – dirty condenser coils can prevent the refrigerator from cooling correctly, causing it to work harder and run more. Clean these coils regularly.
  • low refrigerant levels – a refrigerant leak can cause the system to run excessively. Call in a professional to evacuate any remaining refrigerant and repair the leak before refilling the refrigerant.
  • faulty door gasket – a damaged door gasket can cause warm air to enter the fridge, making it run longer to keep its temperature cool. Replace the gasket if needed.

Being aware of these common problems and their solutions can extend the life of your dometic rm 1350 refrigerator, ensuring it works seamlessly during your travels.

Troubleshooting Steps

Dometic refrigerators are known for their reliability, but no refrigerator is perfect. And when it comes to the dometic rm 1350, troubleshooting the issue can be a hassle. Luckily, many of the problems can be fixed with basic maintenance. Let’s check out the troubleshooting steps below.

How To Check And Clean The Condenser Coils

Condenser coils are responsible for cooling off the refrigerant, so it’s critical to ensure they’re working properly.

  • Turn off the refrigerator and disconnect it from the power supply.
  • Locate the condenser coils and remove any external cover that may be obstructing them.

  • Locate the refrigerator burner and clean it with a soft-bristled brush or replaced if it’s too damaged or rusty.
  • Put everything back together and reconnect the propane supply.

Inspecting The Thermistor

The thermistor is responsible for monitoring the temperature inside the refrigerator and controlling the cooling system. Inspecting the thermistor can help you identify the cause of the problem.

  • Turn off the refrigerator and unplug it from the power source.
  • Locate the thermistor and check if it’s damaged or disconnected.
  • Use a multimeter to test the thermistor’s resistance. If they don’t match, it may/may not be defective.
  • Replace or repair the thermistor if necessary.

Testing For Power Issues

If the refrigerator is not turning on or not staying on, the problem may be with the power source.

  • Check if there’s a loose connection between the power cord and the power outlet or battery.
  • Verify that the circuit breaker is not tripped, both in the rv and outside.
  • Inspect the electrical system, particularly the fuses.
  • Check if the battery’s power level is sufficient.

Repairing The Fridge Door Seals

The door seals maintain the temperature inside the refrigerator, with faulty seals meaning the refrigerator needs to work harder, resulting in higher energy consumption.

  • Check the door seals for damage, cracks, or missing chunks.
  • Clean the seals with a soft cloth and mild soap.
  • If the seals are persistently damaged, replace them with new ones.

By carefully checking and maintaining different parts of the dometic rm 1350, you can quickly solve any issues you may have with the appliance. Remember to clean the condenser coils, inspect/repair the thermistor, repair the door seals, and test for power issues before calling a professional.
