My Dimplex DAC12AC aircooler is blowing out hot air
When you turn the air cooler on it blows out room temp air rather than cool air. I have tried to put the cooler all the way down to 17c but it still just blows hot air and i have no idea why. Oh and when it has been running for more than 30mins an E3 symbol comes up

Sometimes it is difficult to keep your home cool in the hot summer months. Also, some areas of your home may still be hot where other areas are too cool. Try this method to keep your home cool evenly throughout. Before you get started make sure your furnace filter is new. This will allow for maximum air flow.
If your living space is a single floor plan:
Turn the air conditioning on
Switch the furnace fan from auto to on.
Measure the temperature in each room.
Close the vents by about half in the cooler rooms
This will force more cool air into the warmer rooms.
Keep adjusting the vents until all the rooms have the same temp.
If your living space is on more than one level:
Turn on the air conditioning.
Switch the furnace fan from auto to on.
On the lowest level of the house close half of the vents that are the closest to the stairs.
This will force more cool air to the top floor where it is usually hotter.
Cool air will sink from the upper floors which will keep the area near the stairs cool.
Measure the temperature in all the rooms.
Keep adjusting the vents until you have a nice even temperature throughout the house.
I found that leaving the furnace fan on all the time will keep your home evenly cool and comfortable. You may have to replace your furnace filter once a month due to the increased air flow. It will be well worth it in a cooler, more comfortable, and more energy efficient home.
Hi, The hot air is a product of the cooling.... if you stop that then the unit will not cool!!! You need to buy an exhaust kit to vent the hot air outside so that it will cool the room. Otherwise it is just what is called a spot cooler or in other words you are cool if you sit in front of it, but it actually will make the overall room temp. hotter!!
you may have a dirty condensor coil its the coil near where the warm air blows out or maybe a dirty evaporator coil its where the air gets sucked in check both of them and then see whats the air temp going into the evaporator and the temp. coming out of the vents that blow cold air the diffrence should be about 15 - 20 deg f let me know what the temps are ...but first clean the filter and both coils
personally i'd just replace the thermostat, but try pulling the front panel off and look on the circuit board and see if there is a jumper for F/C or any other settings. you may try changing its position. you can also remove the batteries for 15 minutes and see if it resets itself. the only other thing it could be is a wiring issue.
The fan should blow air into the heat sink. The warm air exits the
heat sink at both ends. (It might work the other way, haven't tried
When you have ice in your cooler, you know the thermo-electric element is working well--it's below freezing!
Ice builds up because there is water in the cooler. For example, in
humid weather, you open the cooler, some humid air gets in, and the
cooler temperature condenses the water. You have to empty this water,
either by tipping the cooler, or using a sponge.
You can easily defrost the cooler by unplugging it for an hour or so.
You know it's time to defrost when you hear the fan blades making a
racket because they're hitting something--a thick buildup of ice.
