Question about Haier ESA3125 Wall/Window Air Conditioner
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.
