Re: fan roller and grey fins clogged with dust and mould
You can clean Blower wheel one of two ways. !st would be to remove the wheel and clean with the garden hose or if that is not a option for you then you can buy a can of compressed air and clean it that way but you will get a blast of dust and dirt when unit turns on. Make sure unit and/or power is of when doing this. Keeping your filter mainteneced more often will reduce the build up more.

Here's a pretty simple test - take off the cover if possible, remove the air filter - I know some it's trickier on some and they have a filter that slides in from the side versus a hinged cover, etc. you can pull off or down - but there are metal fins behind that filter. Turn the A/C unit on and try and feel those fins. If they are getting cold and your fan is on - it should be drawing hot air in right there, cooling it down and cool air should come out of the vent. If you turn the A/C on and feel those fins - hear the humming - but they are not getting cold - you have a bigger issue. Basically, your compressor isn't sending refrigerant through the coils and there's nothing to cool the air down with. *Could be other components - but that's a pretty basic test just to check functionality. If it's getting cold - but you're not blowing cold air - those fins could just be clogged with dust, etc. You have to be careful cleaning those as they bend easily. They sell special cleaner for them (you'll want to use it outside - usually an acid based cleaner) and a device that looks like a comb to get in between the fins to straighten if they get bent. Word to the wise - those fins being straight and clean allow the air flow to come through unrestricted - definitely less is more on the cleaning side; you'll want to be very careful. All The Best and Good Luck - Fins to check temp below -
Does your air condition have switch or some kind slider that has inside air or outside air on the unit, cause if its on outside air intake then that's why you have dust coming thru your air con and throwing dust cool air around your unit or house, switch it back to inside air to forever keep out that dust....!!!!! Thank You
Refrigerant Types in a Central Air Conditioner
There are 2 different types of air conditioning refrigerant currently used in residential cooling systems. R-22, commonly referred to a Freon and R410A, a blend considered to be more environmentally friendly, sometimes called Puron.
R410A (sometimes known as Puron), is the industry's choice to replace R-22 in central air conditioning systems. It is less reactive with the environment while having the same home cooling characteristics of R-22. R410A is not interchangeable with R-22-you choose one or the other and your air cooling equipment is designed to operate with it. When you purchase a R-410A system, a new line set is included with your central air installation as well as a new evaporator coil. Our experience with R-410A has been excellent. New cooling systems have been dependable and efficient, as well as operating quieter! R-410A is the refrigerant of the future!
Less reactive with the environment
Replaces R-22 in the year 2020
Cannot be used with R-22 systems
Quiet and dependable
Freon, R22, heat pump refrigerant
R-22 also known as Freon has been used for decades as the refrigerant in central air conditioning systems. However it has been linked to Ozone depletion and has therefore been banned from being manufactured after the year 2010. It's price will increase as the supply decreases.
Not 100% sure but an E1 error on a unit which is sourced from the same place as Electrolux air cons, means that the pipe sensor on the indoor unit has failed. You will need to confirm this with Electrolux. They carry a 5 year warranty, so you may be in luck.... hopefully
These is because you have not service your air-con for a long time. The cooling fins are clotted with dirt & dusts accumulated for a long period of time, and the water vapour caught between the cooling fins turn into ice when you set lower the temperture for the air-con. Moreover cool air from the blower/fan cannot pass thru', the cooling fins to regulate the cool air into your room.
You have to get the professionals to do a service on your air-con.
