Solutions to RV Air Conditioner Dripping Water Inside

If you own an RV, you know how important an air conditioner can be for maintaining temperature inside your vehicle. However, one common problem that many RV owners encounter is water dripping from their air conditioner.

This can be caused by a variety of issues, such as a clogged drain line, a faulty thermostat, or even an improperly installed air conditioner.

Whether you are a seasoned RV owner or a newcomer to the world of recreational vehicles, the solutions provided here can help you to enjoy a comfortable and hassle-free RV experience.

Possible Reasons of RV Air Conditioner Dripping Water Inside

Here are some possible reasons why an RV air conditioner may leak water:

• Clogged drain line.
• Faulty thermostat.
• Incorrect installation.
• Worn-out seal.
• Frozen evaporator coils.
• Leaky water pump.
• Blockage in the evaporator pan.
• Damaged air conditioner unit.

Is RV Air Conditioner Water Dripping a Serious Issue?

Water pouring from an RV air conditioner can be a sign of a more significant issue that has to be fixed. For instance, if a clogged drain line is causing the air conditioner to leak water, the water may not be able to exit the unit properly.

As a result, it will gather inside the unit and possibly causing damage. An RV air conditioner that is leaking water due to a defective thermostat or improper installation may run inefficiently and perhaps lose electricity.

Additionally, if the air conditioner is consistently dripping water, it might be due to a broken air conditioner or a roof leak. In these situations, it’s crucial to take care of the problem very once to limit further harm.

Steps by Step Guide to Fix an RV Air Conditioner Dripping Water Inside

Follow this step-by-step guide to fix your RV’s air conditioner dripping water inside.

Locate the Source of the Leak

Turn off the air conditioner’s electricity first, and then look for the leak’s source. You might be able to see this from the exterior of the unit, or you might need to take off the cover to view the interior of the air conditioner.

Before starting any repairs, it’s crucial to cut off the electricity to the air conditioner because working on electrical components might be risky.

Inspect the Drain Line

To see if the drain line is obstructed, check it. Since the drain line is in charge of removing extra water from the air conditioner, if it is blocked, water will drop out eventually.

Simply use a pipe cleaner or other similar instrument to remove any obstructions or debris from the drain line to resolve this problem.

Examine the Thermostat

If the drain line seems to be clear, make sure the thermostat is operating properly.

The thermostat regulates the inside temperature of the RV, and if it malfunctions, the air conditioner may operate longer than necessary and create more water.

Consider changing or fixing the thermostat to resolve this problem.

Check the Installation

If the thermostat appears to be functioning properly, check the installation of the air conditioner to make sure it is tightly fastened and sealed.

If the installation is done incorrectly, leakage may result. Have the air conditioner professionally reinstalled to resolve this problem.

Look for Any Damage

If the installation seems to be done correctly, look around the air conditioner for any worn or damaged seals.

If these seals are worn down or damaged, water may be able to flow out since they aid to prevent leakage. Replace the seals with new ones to resolve this problem.

Inspect the Evaporator Coil

Next, check to see if there are any frozen evaporator coils within the air conditioner. In the event that the evaporator coils freeze, water may leak out when they defrost.

Allow the coils to thaw in order to resolve this problem, and make sure the air conditioner is set to the proper temperature.

Check the Water Pump

Look for any signs of wear or damage on the water pump. The water pump is in charge of circulating water throughout the air conditioner; if it is malfunctioning, water may seep out.

Consider changing the water pump to resolve this problem.

Observe the Evaporator Pan

Look for any obstructions or debris in the evaporator pan. Since the evaporator pan is in charge of gathering extra water, if it gets clogged, water may flow out.

Remove any obstructions or debris from the pan to resolve this problem.

Still Cannot Fix?

The air conditioner unit itself may be damaged or have a manufacture defect if none of these fixes the problem. In this situation, you might have to get the air conditioner replaced or have a professional fix it.

Always exercise caution when working on the air conditioner in your RV. It is important to seek the help of a specialist if you are unsure how to resolve the problem or feel uneasy carrying out any of the preceding methods.
