I have and 18K BTU wall unit. It worked fine for years. Yesterday it worked as normal. Today when we turned the fan on it hummed. when we turned the knob to low A/C it hummed louder. I checked the fan/motor shaft and it turns freely and there appears to be nothing wrong. What's the problem, the Cap, the main power knob? Help.
A real hummer. humm can be the sound of a short.but it sounds since u did only turn the fan on it hummed ...fanns are blower motors in acs the motor I bet ate it and needs a new one no way of fixing the motor but most are easy and cheap to replace...go or call an ac applance man ...see if he got a good used one for you or go the manufacture take model make serial no. sometimes u can spin the fan while on and it takes off again...this is dangerous so use a plastic long something but will dy again after u turn it off.

It probably has something shorted to ground or the compressor or motors are stuck causing a high amperage problem. The breaker is probably fine but it also could be weak but normally its the compressor or a component has faulted to the compressor. If the unit immediately trips breaker its probably shorted to ground. If the unit struggles to start and a few seconds pass before it trips then it may be a component fault.
I know that a Island Air units come in all shapes and sizes and they make a ton of different units. They are made in new york thats who I would use. I would definitly go with the 12,000 btu unit 500 square feet needs 12,000 btus 10,000 is under sized. 500 square feet divided by 500 = 1 ton of cooling. let me know if I can further assist. http://www.islandaire.com/
This is normal, the noise you here is most likely ice build up on the condenser coils. when the outside temperature is under around 15c ice will build up on the condenser coils it then falls and hits the fan blades. this will also happen if the unit has been running for a while. there is no need to spay water into the unit as this can cause damage to the electrical components.
First off, my model # is Emerson Quiet Kool 10HW42K. No it is not yet solved, however I am reaching out to a number of sources. Was hoping to get a simple answer since it is not a "repair" problem, but rather a "replacement problem". I am looking for another AC that will fit the original sleeve.
