Lost Your Everstar Portable Air Conditioner Manual? Here are Tips for Fixing the 9 Most Common Problems

If you picked up Everstar portable air conditioner at Home Depot a few years ago, then you know how great these little machines are. These portable units do a fantastic job keeping you cool during the dog days of summer.

But if you’re anything like me, you probably have no idea where you put the manual. Since they don’t make these air conditioners anymore, it can be a bit tricky tracking down information about these portable air conditioners.

Mobile air conditionerDon’t worry. We’ve got you covered.

Below you will find a description of the nine most common problems that people have with these Everstar units. And we have even provided a do-it-yourself fix for the most common problems that we have seen with these units.

Most issues can be dealt with in a just a few moments. And the most expensive DIY tip we have for you below will set you back about 20 bucks.

So stop pulling the garage apart and digging around in all boxes to try to find the manual. Everything that you need to know will be outlined here.

Problem #1: “Help! My Everstar MPK-10CR Isn’t Cooling and It Keeps Flashing P-1!”

By far, the most common problem that we see with the Everstar units is that the P-1 indicator light is flashing. While this may look ominous, the reality is that the P-1 light visit very simple problem to fix.

Basically, the P1 means one of two things. First, it can mean that the water tank has been bumped out of place. The unit flushes this signal so that you can replace the water tank so that water does not leak into the other components.

The reason that you will see P1 light is because the unit is telling you that the condenser unit is full of water. This, too, is a pretty easy fix. Simply, drain the water tank.

Here is how you do that:

Step 1–Remove the drain plug, which will be located on the back of the unit. If you still have the drain hose lying around, go ahead and attached that to the drain plug. You can use this drain is to pull the water out of the unit.

If you don’t have the drain hose, simply remove the plug and tip the unit back into a bucket to remove the collected condensation. Depending on the unit you have, you may also be able to remove the entire water tank and empty the water out.

Step 2–Make sure that you carefully replace the water tank if you have removed it. The dehumidifier will begin pulling the moisture out of the air in about 5 minutes after the compressor gets running again.

If you use your Everstar unit in your basement, there is a nifty feature you might not know about. Basically, if you have a floor drain your basement, you can set up your air conditioner so it is on the “continuous drain” option. To do this, you simply keep the drain hose discussed earlier connected to the drain plug and feed it down into your basement floor drain.

Problem #2: “My Everstar Air Conditioner Won’t Work with My Extension Cord!”

Another common problem with the Everstar units occurs when people move them or someone picks up a used unit and doesn’t understand the Lit bulbelectrical specifications.

While these machines are tiny, they do use a decent amount of power and draw 9.6 amps when they’re in cooling mode. To be safe, it is best to run them in your typical 15 amp household grounded receptacle.

Some folks have run into problems when they have tried plugging the unit to a wall outlet in their home that is not properly grounded. If you are concerned about this, make sure that you talk to a certified electrician.

Another thing to keep in mind here is that you should not use a plug adapter or an extension cord with this unit.

Problem #3: “Someone Told Me the Everstar Windowless Air Conditioner Doesn’t Need to Be on a Window Sill. What’s the Deal with this Vent Hose?”

It is a bit of a misnomer to call the Everstar units “windowless”. In fact, all portable ac units have to be situated near a window or sliding glass door so that they can be vented properly using the exhaust hose.

Another common problem that we see with the Everstar units is that the iStock_000008802179_ExtraSmall-1exhaust hose is improperly attached to the window.

The Everstar units come standard with a window kit to help you set up the vent with either a horizontal or casement style window. People often get their units set up and then find that they aren’t working properly.

One of the most common issues that we see with the venting, however, is that the water tank can be accidentally displaced when you move the unit around. If this happens, you will be given the P-1 warning light as discussed above.

So if you have recently moved your unit or you just re-installed it for the summer, simply take a few moments and make sure that the water tank is in the correct position.

Another common complaint that consumers have is that the plastic tubing for the event can get cracked and fall apart over time. After all, the hose is situated right next to the window where it is exposed to harsh sunlight every day.

If this happens, you’ll need to track down a new one. Finding a replacement hose can be a bit of a pain, however, since they don’t actually make these units anymore.

Your best bet is to call around to a few local air-conditioning shops and ask them if they have a portable air conditioner hose that you can purchase.  We’ve gone through a few of these hoses with our portable unit and they generally cost about 15 or 20 bucks to replace.

While some folks have tried to use a dryer hose as an alternative to the AC exhaust hose, we don’t recommend it.  Not only might this void your warranty on the unit, but you really want to make sure that you have the correct size exhaust hose for your Everstar unit.  Since most dryer vent hoses are only 4 inches in diameter, they will not fit snugly in the 5-inch exhaust hose area on your Everstar unit.

Another common question regarding the hose comes up when people want to have one that is longer then the 5-foot standard hose.  Some folks want to use the unit in a room that doesn’t have easy window access (like a basement) or they want to put the unit further away from the window for better cooling.

You can find vent hoses they go up to about 9 feet. As mentioned above, just call around to your local air-conditioner shops to see what they have in terms of portable air conditioner hoses.

Do bear in mind, however, that you don’t want to then the hose bent at an angle greater than 90° at any point. If you do this, the venting hose will be much less effective and the air conditioner will simply not cool as well.

We have one final note about the venting hose. Never, ever use this portable air conditioner without it. If you let this unit – or any portable ac – run without a vent, the hot air will come out of the back of the machine and right into the room that you are trying to cool.

Problem #4 – “The Unit Seems to Turn On and Off Like It Is Possessed!”

Sometimes, you might hear the fan operating but you notice that there’s not any cool air coming from the machine. This is a common problem at the beginning of the summer season or if you have just picked up one of these units used.

The good news is that the fix is pretty simple. You simply need to reset the thermostat.

In all likelihood, the thermostat on the unit has been set to a specific Digital Thermostat and male handtemperature. Once the room reaches that temperature, you may be facing a situation where the machine has been programed to cool only until that level is reached.

These Everstar units come with a timer set up that can be a bit confusing. Here are tips for resetting it.

Begin by holding down mode key until you see the cool indicator light.

Then press the down arrow or up arrow keys until you reach the desired temperature setting. This will show up on the LED display window. You can choose a setting anywhere between 62°F and 88°F.

The green indicator light should come on to tell you that the air-conditioning mode has begun. Don’t worry if there is a delay, it normally takes up to 30 seconds for this cycle to begin.

The next setting that you want to take a look at is the fan setting. You have 3 choices from which to choose: high, medium, or low.

Problem #5: “Uh-oh. The Compressor on My Everstar Portable Air Conditioner Stopped Running!”

Another common complaint that we hear about these Everstar units is that the compressor seems to be broken. In all likelihood, however, the compressor is fine and there’s just a minor adjustment that needs to be made.

As discussed earlier, if the water tank gets bumped or dislodged somehow, the compressor will go into its safety feature and will stop operating.

Moreover, it will automatically begin flashing the P-1 light which indicates that the tank is full.

Many people are confused by this – especially at the beginning of the summer season – because they know that the tank could not possibly be full. This is just a little quirk of the Everstar unit that will automatically indicate that the tank must be drained.

One other thing to keep in mind is that the compressor simply will not run as long as the red P-1 light is flashing.

So here is your troubleshooting guide if the compressor stops:

Step 1:  Check to see if the water tank is in fact full. If it is, follow the instructions above to empty it.

Step 2: Determine if the water tank has been jiggled out of place during a move or repositioning. If so, simply slide it back in place.

You know that you have solved the problem when the red light stops flashing.

Problem #6 – “We Just Had a Brown Out and My Everstar Air Conditioner Stopped Working Even When the Power Came Back On.”

Another common issue that we see with these units is that they can sometimes have problems if you are hit with a blackout or brownout during the hot summer months.

For example, if the unit is in a cooling for dehumidifier in mode and it loses power temporarily (say 3-5 minutes or so), the compressor protection circuit will be triggered. This results in a green flashing light on the mode indicator, which will last for about 10 seconds. This is just a safety check so that the machine can detect whether the compressor is protected or not.

You will notice that the compressor does not run during this “compressor protection” phase. Don’t worry. This doesn’t mean that anything is wrong.  Just wait for about 5 minutes and the compressor protection feature should automatically deactivate.

Problem #7: “How Can I Set My Everstar Windowless Air Conditioner So It Starts Cooling Before I Get Home from Work?”

Most Everstar portable ac units come with an automatic timer that allows you to program the unit to switch off or turn on the specified time.

Some people run into problems with this feature because the unit can be a bit persnickety with the timer.

For the auto–off feature to work, make sure that the unit is running. And alarm clockthen select the number of hours you wish for it to remain running. The silly thing about this feature is that you will have to set up the timer on a daily basis. The unit will not remember it from day-to-day. Also, bear in mind that if the unit suffers a power outage, it will have to be reset.

On the other hand, perhaps you want to set your air conditioner so that it automatically turns on before you return from work. To set the auto–on feature, you must ensure that the unit is not running. Then use the arrows to select the number of hours you want to pass before the unit turns on automatically. Again, this will have to be completed on a daily basis.

Problem #8: “Where Can I Get Everstar Portable Air Conditioner Filters?”

Because you can no longer buy these Everstar units at your local Home Depot, it is imperative that you take good care of your air conditioner to ensure that it lasts for years to come. Here are some tips for basic maintenance that should be completed routinely.

Before you take care of any of these issues, make sure that you unplug the unit from its electrical source. Also, do not use any chemical cleaners on the outside of unit because they can wreak havoc on the plastic casing.

The most common maintenance step  (and one that many users often neglect) is to keep the air filter clean. If you let the air filter get too dirty, the efficiency of your Everstar unit will decrease tremendously. Ideally, you should remove the air filter and clean it at least two times a month.

Here are the steps you should take to get the air filter nice and clean:

Step 1: Unplug the unit and turn it around so that the back is facing you.

Step 2: Grab the air filter tab. Release it by pulling it out first and then lifting it up.

Step 3: Use your vacuum to clean out all of the dust and dirt on the filter. You can also wash it with warm soapy water. Dishwashing soap is the best.  Make sure that you rinse the filter until the water runs clean and allow it to dry completely before you return it to the machine.

If your air filter isn’t particularly bad shape, consider buying a new one. Simply take the old filter to any home improvement store and ask them for a replacement. Filters can be fairly cheap, starting at about 10 bucks.

Also – and this is important – never, ever run your air conditioner without an air filter installed. You can wreck your unit if you don’t have an air filter in their while it is running.

Problem #9: “The Remote Won’t Work and I’m Too Hot to Walk Over and Turn on the Machine.”

If you are still lucky enough to know where your remote is (we lost ours ages ago), the most common complaint that we see is that the darn thing just stops working. In all likelihood, the fix is simple. It probably just needs new batteries.

Here are a couple of things to keep in mind regarding the batteries for the remote:

  • Make sure that you are using two AAA batteries.
  • Never use old batteries. This can cause the remote to wig out.
  • If you are going to use the remote for over two weeks –or you are putting the unit away for the winter – make sure that you remove the batteries. If you don’t, they can potentially leak and ruin your remote.

The way to tell that you must absolutely replace the batteries is that when you press the buttons, there is no beep from the unit.

So there you have it. These fixes will solve the most common problems with the Everstar unit in just a few minutes.

Good luck and stay cool!
