20 Most Recent Haier ESA3125 Wall/Window Air Conditioner Questions & Answers

Since you are saying it hums, I interpret that to mean that both the fan and compressor are not running?
If that is the case it points to the capacitor, it is very common to have a dual capacitor which handles both fan and compressor.
The odds of both components dialing at the same time are remote, capacitors fail on a regular basis. Anything beyond this is not economically serviceable.

Hi, what you have is called a Heat-Pump, and it also has a reversing valve that reverses the flow of freon through the unit. In the winter time, the outdoor unit becomes the evaporator coil and the indoor becomes the condenser coil. You have what is called a defrost board and also defrost thermostats on the outdoor unit. When the unit starts to build up ice on it, it has a defrost timer and along with the stats will terminate a defrost and melt the ice away. You should see the fan shut down and the unit will start to throw off steam, almost looks like smoke. Ice is a normal thing to happen on heat-pumps as long as it goes through a defrost cycle every so many hours to keep the ice from getting real thick and the unit stops heating your home. So, if your not having heating problems, and the ice does not keep building and getting thicker and thicker, this is normal, and there is nothing for you to worry about. If you have any more questions, feel free to contact me and I will help you out. Please don't forget to rate this post for me, as I know you will be kind.

Hello my name is Heath it will be my pleasure to assist you. The first thing to check is the filter in the furnace or air handler. Also check the inside coil to be sure its not frozen up. Does the air coming out feel cold? It sounds like the unit could be low on charge which means it has a leak and should be leak checked repaired and properly charged. You would need refrigeration gauges to put on the system in order to properly check the refrigerant charge in the system. One other thing could be a dirty condenser coil. Turn the power off to the unit and use a garden hose with a strong nozzle and spray water through the whole coil to try and blow any dirt or debris through the condenser coil in the outside unit.

Indoor room temp sensor defective replace it.

Unfortunately, there's not much you can do. The E1 error code indicates a sensor shutdown. However, you can try turning the unit OFF & unplug it for 15 minute. Then plug it back in and turn it ON. If the electronics reset and reverted back to the original factory setting, you can set the controls as you like.

If you continue to get the E1 error code,, contact Haier Customer Support 1-877-337-3639.

The water and noise you hear is from the fan blades hitting backed up water in the drip pan. This occurs when the drain hole near the rear of the drain pan is clogged and/or the rear of the unit does not have enough downward tilt. Which allows the water to flow freely to the drain hole. The general rule of thumb for downward tilt is 1/4" to 1/2". Correcting these to things should solve the problem. Be sure to turn the unit OFF & Unplug it, before attempting remedial service work on the unit.

Hope this helps you and thanks for choosing FixYa.

Where the unit drains is clogged it sounds like so your fan blade is hitting the water and scooping some of that water indoor. look where the condensate drains and clean that and it should be fine

Two things generally cause the problem you're having.

The drain hole in the drip pan near the rear of the unit is clogged and/or the rear of the unit is not tilted down enough for the water to flow to the drain hole. 1/4" to 1/2" is the rule of thumb for the rear tilt.

Finding the drain hole is often a challenge. As, the clog can blend in with the drain hole. Persistence and patience are the key to finding it. A pipe cleaner works well to clear the hole.

Good job, on cleaning the air intake filter. Some folks overlook that. Since that helped some, I believe you need to clean a little further. Like the cooling coils and the cooling fins for the compressor. But, before attempting any cleaning turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet.

You can clean the coils with warm water and liquid dish washing liquid,. Rinse and dry thoroughly. When dry, apply a light coating of WD40.

The fins can be cleaned using an old toothbrush and a vacuum cleaner that has a hose and brush attachment or crevice tool.

Completing this Annual Type Maintenance should provide significant results.
