Sounds like 1 of 2 problems. first, check the condensor coil for dust, dirt, lint on the inside of the unit. this is the coil thats on the back of the unit that is outside. it can be sprayed out with a garden hose. make sure the unit is unplugged and let it drain for a hour or so. if the coil is not dirty, then the unit has developed a freon leak and needs to be serviced.

Well if you buy a 220 system it will be 220 volts. All the bigger systems like for whole house will be 220. some smaller under sink models will be 110. There is no polarity since it is AC. If you find something that says polarity on a on demand water heater then somebody at the factory is smoking something. 110 has 3 wires. all tests need done with a multimeter on the AC setting. Black wire will be 110 volts AC, White wire is neutral and green wire is ground. 220 system also has 3 wires. Colors can vary a bit here but usually it goes like this. Red wire is 110 AC - Black wire is 110 AC and white wire is Neutral or ground. Test to ground they read 110 Volts AC test to each other they read 220 AC because they are out of Phase to each other. PLEASE note. Always get a certified electrician to work on these units. If you feel you are just as good as any electrician, please make sure you have a family member nearby with a phone that can dial 911. 110AC can kill you and 220 AC can kill you faster and deader.
To know whether any particular unit is 110 or 220 we would have to have the model number to look it up. Some can be either and in this case the only way to know is to take the junction box apart. If it is just plugging into a regular wall outlet then it is 110. If it looks like a special plug or like a dryer plug then it is 220. Hope that helps. Have a great weekend.
It's obviously on the 12voltDC circuit of the AC unit. Sounds like thermostat, or a relay in control box is faulty or bad connection. If you remove cover on ceiling assy., you should be able to hear it in the control box. There should be a model number on the ceiling assy., get back to me with that number and I can better pinpoint which relay. Also, try moving all thermostat buttons and temperature controls back and forth quickly to see if it may clean off a dirty circuit in thermostat as well. Make sure your AC hydro breaker is off when working with ceiling assy. just to be safe.
either the heater core is stopped up or the blend door is stuck turned to cool. the blend door motor's on these are know to go out. so i'd start with that. its under the dash in the middle and usually kinda tough to find. itll be a square plastic box about 2 or 3 inches wide and the same tall with an electrical connector on it bolted to the heater case. when you're turning the temp from cool to hot the blend door isnt turning i'd say
indicates gas pressure and condenser cooling problems
check the condenser fan is working properly and have the gas pressures checked by gauges
check that the evaporator fins are clean and not blocked as ice build up will cause the same indications
check and see if you are getting ac 110 volts to your water vave when trying to start the unit. if no power check your breakers and /or the incoming power to your dishwasher if they are ok and show 110 voltage coming to the unit then you probably have a control board or touchpad problem which would need a little more detailed check out.
If you do have ac 110 to your water valve then you may just have a bad water valve. Because the washer has to fill first. Hope that helps!!
If you have just installed this unit in your window for the
season, you may want to wait a day or so, for everything in the unit to
settle, and try again. You make have shaken it up a bit too much. If not.....sounds to me like it is kicking out on high head pressure. This happens when refrigerant gets too low, or there is air in the refrigerant system. There is nothing you can do to solve this problem, except take it to a repair shop. If I am correct what happens is you turn the unit on, and the fan and compressor start simultaneously, then after a few seconds (maybe up to a minute) the compressor kicks off, and the air gets warm, then the compressor kicks on for a few seconds, and we repeat. This is actually a safety mechanism for the compressor motor so it does not run without refrigerant. (That would destroy the pump.)
