One thing you can try is to hold down on the power button and plug the unit in. Hopefully you will hear a "beep". Then you need to unplug it for a minute and plug it back in. This is a known procedure to clear error codes from the control computer on units similar to yours, so it might possibly work. Something else you can do is download and look through the Users Manual for your model, which is at this URL: --> Hope this helps! ;)

If the Error Code for a Haier 10K window unit shows E0, all you need to do is to order a Haier A0011800279G Power Control Board. Put it in and the problem is fixed. Works like new. Found on Ebay for 39 bucks brand new.

Yes your thermostat is shorted. It's just not shutting the unit off ever. A thermostat is something you can touch as a user, so no it's not that hard to get to for replacement. Also have the unit unplugged while learning how to repair your appliance.

Coils are freezing in the room air conditioner

Hello my name is Heath it will be my pleasure to assist you. First thing to do is turn the unit off and check the filter then if the filter is okay check to see if the blower comes on when you put the fan switch on the thermostat from auto to on. If the blower isn't coming on then there could be a problem with the blower motor. If the motor is running then turn the system to cool and turn the setting down to where the air should be on. Then check the outside unit and be sure the outside unit is running if the outside unit is not running go to the house panel box and check the breaker to see if any of them are tripped or off. If there off turn them on and check the outside unit again. If all is running and you get no air flow through the vents then the coil could be frozen. If the unit is frozen turn the thermostat to off and leave the indoor blower on by leaving the fan switch in the on position for a couple hours till it thaws. If the unit froze up then there could be a problem with the a/c system most likely low on refrigerant as a result of a leak. I would have it leak tested and repaired if this is the case.

Hi, I would say you have a problem in the cord its self. Even though it lights up, its not getting power to the controls. I would go to a hardware store and get a new cord and take care of the problem. When you replaced the socket in the wall and the fan came on, you just got lucky and the cord moved in the right position to start the fan. I am sure the cord is either faulty, or the connections where the cord wires in are not very good. Please remember how the cord is wired, even if you have to draw a picture. It will hook to a capacitor if it is a 220 unit. Just draw you a diagram.

With the unit unplugged, open the cover and check the alignment of the fan. If the fan is stuck or rubbing against the fan cowling, adjust the fan motor's mounting hardware so that the fan turns freely.

Take care.

your wiring is melted or shorted under the electrical access panel where the selector switches are. You will usually see melted wires and burnt ends. Your compressr start wire has melted to a hot. good luck and remember to unplug the unit first

Why won't my Reddy Heater R55 run with the upper shell on? My Reddy Heater R55 will not run properly with the upper shell installed. Initially, the unit wasn't sparking, so I replaced the transformer ignition control and installed a new spark plug. That fixed the sparking issue. However, this new shutoff issue was discovered. I elected to replace the lint filter, intake filter, and output filter, as those pieces all looked pretty old. The filter end cover was cracked on the side and spitting out air, which I replaced. After the same issue continued and the unit shut off after a few minutes with the upper shell on, I replaced several other things. This included the photocell, nozzle and adapter, the adjusting screw, spring, steel ball, and the 1/8" ID air and fuel lines. After digging deeper into this, I noted the old 3/16" ID air line was leaking with a bit of soapy water, my dad's best trick for finding leaks. One thing to note, when I have the upper shell off, I have set the pressure to 3.4 PSI (per the side label), but when I put the upper shell on, the PSI drops to below 3.0 unless I hold the gauge still. When I hold it, the gauge reads 3.4 PSI. A couple of final things to note on this journey. 1) The fuel cap does not look to have a gasket but it seems to breathe properly with the hole in the center of the cap. 2) Before any issues started, I was running pump kerosene. Since then, I filled up with 10 gallons of jet fuel at a local airport and wondered if I got bad fuel from them. I plan to run through the last 7 gallons or so of jet fuel with the upper shell off and then try a couple of gallons of pump kerosene to see if that resolves the problem. Beyond all of my attempts, I am at a loss and could use some help. I've spent more on these repairs than the unit is worth but started the process in hopes of fixing the heater, as my wife's grandfather gave it to me a couple of years ago. In hindsight, I should have just bought a new unit, but here I am.
