Top 20 EdgeStar Portable Air Conditioner Heater Questions & Answers

Empty the condensate (water) bin.

The hose is only needed to pump out hot air while using the AC features and not needed at all for heater functions.

I have an Edgestar AP 420HS and I need to replace the horizontal hamster wheel type exhaust fan that is rattling badly. I removed all screws and still can not remove the back of the unit. Two screws required a 7 inch long hex screw driver. Please post any information that may be helpful.

Hi lbgirl35,

There is a possibility that your coil is dirty and freezing that may cause the problem. Find the filter panel and open it and check to see if the filters are dirty and you should be able to see the evap coil right there the filter is right in front of it. Do not flatten them out just use some household cleaner be careful to read if they will damage aluminum some will. spray a safe cleaner on and just rinse it off.

Hope it helps.

Thank you for using FixYa.

By law you can not purchase refrigerant
without a licence

E-1 indoor room temp sensor defective. Replace it.

Check thermostat setting and also heating sensor.

the float switch which sits down in the bucket may be stuck, try and find it and give it a wiggle to free it up.

will probably find it by removing the bucket and looking in the space where it normally sits.

cheers

yes of course find how to open system an locate the coils that seems like an over heat problem with the compressor can not breath so clean the coils real good with coil cleaner ,if you dont have that just clean it for now with pressured water that will take care of your problem

I dont know this model unit specifically, how ever there should be a panel you can open to access the drain tray. See if the front panel opens ( should not need any tools to open it)

makes no difference, as long as the ducting is not kinked.
keep in mind heat rises
so obviously if you could dump the heat elsewhere, away from the area you are cooling, then it would not creep back up through the floor. If your flooring is well insulated it will not matter.

check the start capacitor or the fan motor

Google Air Conditioning parts on the web. plenty of parts there. Need Model serial and make.

sounds like its in defrost mode and the electric aux heat is not working

Please read the problem carefully and address the problem. These reponses fail to do that! The problem is in the balancing of the circulating exhaust fan which is like a hamster wheel lying on its side. Once this begins to make noise, it is due to breakdown completely. This is a problem that should not happen and is built in obsolescence. It needs to be maunufactured stronger.

You have to open it and clean out the water passages.

how old now the unit..? is it new?

There are 3 possibilities beginning with the most likely problem

1) If your heater heats up for a few minutes and then quits, chances are there is a blockage in the air flow, check for dust and grime blocking the air intake coarse filter , airgun blow to clear accumulated dust and otherwise clean the coarse filter .
2) If the heater fan blows but there is no warm air, the heating element needs renewal ( this happens very rarely)
3)If the fan stalls and the heater heats up and the thermostat kicks in, then this will be not be a DIY job. This is least likely as you said the air cooler works.

This could apply to at least one of your units. Apparently these models have had some trouble with the compressor capacitor wires coming loose. If they're barely touching they could cause the compressor to run intermittently and possibly overheat. The compressor runs in heating and cooling mode.
