Before diving into cleaning, it’s important to understand why your air conditioner might develop an odor. The LG LT0816CER is a portable unit that cools and dehumidifies the air, which means it pulls moisture from the room. While this is great for comfort, it also creates a damp environment inside the unit—perfect for mold, mildew, and bacteria to grow.
Common causes of bad smells include:
- Dirty or clogged air filter: Over time, dust, pet hair, and allergens accumulate on the filter. When air passes through, it picks up these particles and spreads them into your room.
- Mold or mildew on evaporator coils: The coils get cold and collect moisture. If not dried properly, they become breeding grounds for mold.
- Stagnant water in the drain pan or hose: Water that doesn’t drain properly can sit and develop a foul smell.
- Accumulated dust inside the unit: Dust settles on internal components and can burn or rot, creating odors when the unit runs.
- Poor room ventilation: If your room is dusty or has strong odors (like cooking smells or pet dander), the AC will circulate them.
Understanding these causes helps you target the right areas during cleaning. Most odors are preventable with regular maintenance, so let’s get into the step-by-step process.
Step 1: Turn Off and Unplug the Unit
Safety first! Before you begin any cleaning, always turn off your LG LT0816CER and unplug it from the power outlet. This prevents electrical shock and ensures the unit won’t accidentally turn on while you’re working on it.
Let the unit sit for at least 15–20 minutes to cool down if it’s been running. This gives internal components time to settle and reduces the risk of burns from hot parts.
Step 2: Remove and Clean the Air Filter
The air filter is the most common source of bad smells in portable air conditioners. It traps dust, pollen, and other particles, but if it’s not cleaned regularly, it becomes a smelly mess.
Locate the Filter
On the LG LT0816CER, the air filter is located behind the front panel. To access it:
- Gently pull the front grille forward. It’s usually held in place by clips.
- Once the grille is removed, you’ll see the filter—a rectangular mesh panel.
- Carefully slide the filter out of its slot.
Clean the Filter
There are two ways to clean the filter, depending on how dirty it is:
For light dust: Use a soft brush or vacuum cleaner with a brush attachment to remove surface debris.
For heavy buildup: Wash the filter with warm water and mild dish soap. Gently scrub both sides with a soft cloth or sponge. Avoid using harsh chemicals or scrubbing too hard—this can damage the mesh.
After washing, rinse thoroughly and let the filter air-dry completely. Never reinstall a damp filter, as moisture can promote mold growth.
Reinstall the Filter
Once dry, slide the filter back into place and reattach the front grille. Make sure it clicks securely into position.
Pro Tip: Clean the filter every 2–4 weeks during heavy use, or monthly during lighter use. This simple step can prevent 80% of odor issues.
Step 3: Wipe Down the Evaporator Coils
The evaporator coils are located behind the filter and are responsible for cooling the air. Because they get cold and collect moisture, they’re prime spots for mold and mildew.
Access the Coils
After removing the filter, you should be able to see the coils. They’re usually a series of thin, aluminum fins. Be gentle—these fins are delicate and can bend easily.
Clean the Coils
Use a soft-bristled brush (like a toothbrush or coil brush) to gently remove dust and debris from the fins. For stubborn grime or mold, use a no-rinse coil cleaner spray designed for air conditioners.
How to apply coil cleaner:
- Spray the cleaner evenly across the coils.
- Let it sit for 5–10 minutes to break down dirt and mold.
- Use the brush to gently scrub any remaining residue.
- Wipe away excess cleaner with a dry cloth.
Avoid using water directly on the coils unless the cleaner instructions allow it. Excess moisture can damage internal components.
Alternative natural cleaner: Mix equal parts white vinegar and water in a spray bottle. Spray lightly on the coils, let sit for 10 minutes, then wipe clean. Vinegar kills mold and neutralizes odors naturally.
Step 4: Clean the Drain Pan and Drain Hose
The LG LT0816CER has a built-in drain system that removes condensation. Over time, this water can stagnate and develop a foul smell.
Locate the Drain Components
The drain pan is usually at the bottom of the unit, and the drain hose connects to the back or side. Refer to your user manual if you’re unsure.
Empty the Drain Pan
If your unit has a removable drain pan, take it out and empty any standing water. Rinse it with warm, soapy water and dry thoroughly.
If the pan is not removable, use a turkey baster or small cup to suction out water.
Flush the Drain Hose
Disconnect the drain hose from the unit (if possible) and flush it with clean water. You can also use a mixture of water and vinegar to kill bacteria.
To prevent clogs, run a pipe cleaner or flexible brush through the hose to remove any buildup.
Reconnect and Test
Reattach the hose securely and ensure it’s positioned to allow proper drainage. A kinked or blocked hose can cause water to back up.
Step 5: Use a Natural Deodorizer
Even after cleaning, some odors may linger. Natural deodorizers can help neutralize smells without introducing harsh chemicals.
Baking Soda Solution
Mix 1/4 cup of baking soda with 1 cup of warm water. Stir until dissolved. Use a spray bottle to lightly mist the interior surfaces of the unit—especially around the coils and fan area. Let it dry completely before reassembling.
Baking soda absorbs odors and is safe for most AC components.
Vinegar Spray
Fill a spray bottle with undiluted white vinegar. Lightly spray the interior (avoiding electrical parts). Vinegar kills mold and bacteria and leaves no toxic residue.
Let it sit for 10–15 minutes, then wipe with a dry cloth.
Essential Oils (Optional)
For a fresh scent, add a few drops of essential oil (like lemon, eucalyptus, or lavender) to a clean, damp cloth and wipe the interior. Do not spray oils directly into the unit—they can damage components.
Step 6: Run the Unit in Fan-Only Mode
After cleaning, run your LG LT0816CER in fan-only mode for 30–60 minutes. This helps dry out any remaining moisture inside the unit and prevents mold from returning.
To do this:
- Turn the unit back on.
- Set the mode to “Fan” (not “Cool”).
- Let it run with the fan on high.
This step is especially important if you live in a humid climate or if the unit has been off for a while.
Step 7: Maintain a Clean Environment
Your air conditioner can only do so much. If your room is dusty or has strong odors, the AC will circulate them.
Keep the Room Clean
- Vacuum and dust regularly.
- Use an air purifier to reduce airborne particles.
- Avoid smoking or using strong chemicals near the unit.
Control Humidity
High humidity encourages mold growth. Use a dehumidifier if needed, or ensure the AC’s dehumidifying function is working properly.
Change Bedding and Curtains
Dust mites and pet dander can accumulate in fabrics and get pulled into the AC. Wash bedding weekly and vacuum curtains.
Troubleshooting Persistent Odors
If your LG LT0816CER still smells bad after cleaning, try these solutions:
Odor Still Present After Cleaning?
- Check for hidden mold: Inspect areas behind the fan or near the compressor. Use a flashlight to look for dark spots.
- Replace the filter: If the filter is old or damaged, it may not filter effectively. LG recommends replacing it every 6–12 months.
- Run a deep clean cycle: Some users report success by running the unit with a bowl of vinegar inside the room to absorb odors.
Musty Smell Returns Quickly?
This usually means moisture isn’t draining properly. Double-check the drain hose and ensure it’s not clogged or kinked. Also, make sure the unit is level—if it’s tilted, water may not drain correctly.
Burning or Electrical Smell?
This is serious. Turn off the unit immediately and unplug it. A burning smell could indicate an electrical issue, such as a burnt motor or wiring. Contact LG customer service or a certified technician.
Sweet or Chemical Smell?
This could be refrigerant leak. While rare, it’s dangerous. Stop using the unit and call a professional.

To keep your LG LT0816CER smelling fresh year-round, follow this simple maintenance schedule:
- Weekly: Wipe the exterior with a damp cloth.
- Monthly: Clean the air filter and check the drain hose.
- Every 3 Months: Clean the evaporator coils and inspect for mold.
- Annually: Schedule a professional inspection and deep clean.
When to Call a Professional
While most odor issues can be resolved at home, some problems require expert help. Call a technician if:
- The unit smells like burning or chemicals.
- You suspect a refrigerant leak.
- Mold is growing inside sealed compartments.
- The unit isn’t cooling properly after cleaning.
Regular professional maintenance can extend the life of your AC and ensure it runs efficiently.
