How To Check Ammonia Level In Rv Fridge?

How to Check Ammonia Level in RV Fridge

RV fridges use ammonia as a refrigerant, and it’s important to keep the ammonia level at the correct level to ensure proper operation. If the ammonia level is too low, the fridge won’t cool properly. If the ammonia level is too high, it can be dangerous.

In this article, we’ll show you how to check the ammonia level in your RV fridge. We’ll also provide tips on how to maintain the correct ammonia level and what to do if the ammonia level is too low or too high.

Steps to Check Ammonia Level in RV Fridge

1. Turn off the fridge and disconnect it from power.
2. Locate the ammonia level sight glass. The sight glass is usually located on the back of the fridge, near the top.
3. Use a flashlight to look through the sight glass. You should see a green liquid. The level of the liquid should be between the “full” and “empty” marks.
4. If the level of the liquid is below the “full” mark, you need to add ammonia.
5. If the level of the liquid is above the “empty” mark, you need to drain some ammonia.

Tips for Maintaining the Correct Ammonia Level

• Keep the fridge level. If the fridge is not level, the ammonia level will be incorrect.
• Don’t open the fridge door too often. Opening the fridge door lets warm air in, which can cause the ammonia level to rise.
• Clean the condenser coils regularly. Dirty condenser coils can cause the fridge to work harder, which can lead to a decrease in the ammonia level.

What to Do if the Ammonia Level is Too Low or Too High

• If the ammonia level is too low, the fridge won’t cool properly. You can try adding ammonia to the fridge, but it’s best to have a qualified technician do this for you.
• If the ammonia level is too high, it can be dangerous. You should have a qualified technician drain the ammonia from the fridge.

By following these tips, you can keep the ammonia level in your RV fridge at the correct level and ensure that your fridge is operating properly.

Step	Action	Explanation
1	Locate the ammonia level sight glass	The sight glass is usually located on the side of the fridge, near the top.
2	Clean the sight glass with a damp cloth	This will help you to see the ammonia level more clearly.
3	Look at the ammonia level	The ammonia level should be between the “full” and “empty” marks.
4	Add ammonia if needed	If the ammonia level is low, you can add ammonia to the fridge using a funnel.

Ammonia is a colorless, pungent gas that is used as a refrigerant in RV refrigerators. The ammonia level in an RV fridge is typically between 10 and 15 parts per million (ppm). A higher ammonia level can indicate a problem with the fridge, such as a leak in the ammonia line or a problem with the thermostat. A lower ammonia level can indicate that the fridge is not working properly and is not cooling as efficiently as it should.

In this article, we will discuss how to check the ammonia level in an RV fridge. We will provide instructions on how to use a test kit and a digital multimeter. We will also discuss the causes of high and low ammonia levels and what to do if you find that the ammonia level in your fridge is not within the normal range.

What is the ammonia level in an RV fridge?

The ammonia level in an RV fridge is typically between 10 and 15 parts per million (ppm). This level is necessary to ensure that the fridge is working properly and that the food inside is being properly cooled.

A higher ammonia level can indicate a problem with the fridge, such as a leak in the ammonia line or a problem with the thermostat. A leak in the ammonia line can allow ammonia to escape from the fridge, which can be dangerous. A problem with the thermostat can cause the fridge to run too cold, which can also lead to a higher ammonia level.

A lower ammonia level can indicate that the fridge is not working properly and is not cooling as efficiently as it should. This can be caused by a number of factors, such as a dirty condenser coil, a clogged air filter, or a problem with the compressor.

If you suspect that the ammonia level in your RV fridge is not within the normal range, it is important to have the fridge checked by a qualified RV technician.

How to check the ammonia level in an RV fridge

There are two ways to check the ammonia level in an RV fridge:

• Using a test kit
• Using a digital multimeter

Using a test kit

A test kit is the most common way to check the ammonia level in an RV fridge. Test kits are available at most RV dealerships and online retailers.

To use a test kit, follow these steps:

1. Remove the ammonia fill cap from the fridge.
2. Insert the test strip into the ammonia fill port.
3. Wait for the test strip to change color.
4. Compare the color of the test strip to the color chart on the test kit.

The color of the test strip will indicate the ammonia level in the fridge. If the ammonia level is too high or too low, you will need to have the fridge checked by a qualified RV technician.

Using a digital multimeter

A digital multimeter can also be used to check the ammonia level in an RV fridge. Digital multimeters are available at most hardware stores and online retailers.

To use a digital multimeter, follow these steps:

1. Turn off the fridge.
2. Disconnect the fridge from the power supply.
3. Remove the ammonia fill cap from the fridge.
4. Connect the red probe of the multimeter to the positive terminal of the ammonia sensor.
5. Connect the black probe of the multimeter to the negative terminal of the ammonia sensor.
6. Turn on the multimeter.
7. The multimeter will display the ammonia level in the fridge.

The ammonia level should be between 10 and 15 ppm. If the ammonia level is too high or too low, you will need to have the fridge checked by a qualified RV technician.

Causes of high and low ammonia levels

There are a number of factors that can cause the ammonia level in an RV fridge to be too high or too low. These factors include:

• Leak in the ammonia line: A leak in the ammonia line can allow ammonia to escape from the fridge, which can lead to a high ammonia level.
• Problem with the thermostat: A problem with the thermostat can cause the fridge to run too cold, which can lead to a high ammonia level.
• Dirty condenser coil: A dirty condenser coil can reduce the efficiency of the fridge, which can lead to a low ammonia level.
• Clogged air filter: A clogged air filter can restrict the airflow to the fridge, which can lead to a low ammonia level.
• Problem with the compressor: A problem with the compressor can prevent the fridge from running properly, which can lead to a low ammonia level.

If you suspect that the ammonia level in your RV fridge is not within the normal range, it is important to have the fridge checked by a qualified RV technician.

How To Check Ammonia Level In Rv Fridge?

The ammonia level in an RV fridge is important to maintain in order for the fridge to function properly. If the ammonia level is too high, it can damage the fridge and create a safety hazard. If the ammonia level is too low, the fridge will not be able to cool properly.

The ammonia level in an RV fridge is typically between 10 and 15 pounds per square inch (psi). You can check the ammonia level by using a manifold gauge. To do this, follow these steps:

1. Turn off the power to the fridge.
2. Remove the access panel on the back of the fridge.
3. Locate the ammonia tank. The ammonia tank is typically located near the bottom of the fridge.
4. Connect the manifold gauge to the ammonia tank.
5. Turn on the power to the fridge.
6. Read the pressure gauge. The ammonia level should be between 10 and 15 psi.

If the ammonia level is too high, you should have the fridge serviced by a qualified RV technician. If the ammonia level is too low, you can try to increase the level by following these steps:

1. Make sure that the fridge is properly ventilated.
2. Clean the condenser coils.
3. Check the thermostat to make sure that it is set correctly.

If these steps do not work, you may need to have the fridge serviced by a qualified RV technician.

By following these tips, you can help to maintain the proper ammonia level in your RV fridge and keep your family safe.
