The evaporator can be bent upwards slightly to raise the prongs. The evaporator should be level. Change the water in the inner tank. The ideal water temperature is 50°F-90°F. SNO Titanium ice makers only: SNO 3 in 1 ICE-100S ice makers only: Unit is not switched on. The water level indicator (red ball) is not moving. Water tank is about half full. Turn on the unit using the On/Off switch and press the Start button. Hold a glass of water about 5 inches above fill compartment and pour water into unit. Make sure that the red ball is floating. The unit stops taking in water when the water tank is about half full.

Bottle supporter is not installed properly. Unit needs to be restarted. Bottle has a cap or seal. Make sure the bottle supporter is properly installed with the arrow facing front and center. Turn off the unit for a minute and turn back on then push Start button. Take off the bottle and manual fill the unit with water. Remove cap or seal then reposition bottle back on to bottle supporter. Turn on Power and push Start button. Reduce or increase the water pressure. The unit only takes in water to up to the "Min." line when you first press the "Start" button, then it won't take in water until the 1st batch of ice is dropped. The unit does not take in water when ice making is in process so you will see the low water light blinks through out the process. There is nothing wrong with the unit as long as it keeps taking in water after each batch of ice and the green light stays on.My air conditioner is not cooling! What can I try before setting up a service call?

If your air conditioner is not cooling, there are a few things you can check before scheduling a service call. If you have checked these items above and your air conditioner is still not cooling, call (717)397-2577 or request an appointment .ac unit diy How can I even out the heating and cooling of my home? average price for an ac unitAdjust the registers on the wall or floor in the room where too much heat/cooling is present so that the registers are partially closed. can you run an ac unit without a filterFor example, to get more heat upstairs during the winter, partially or fully close the registers downstairs to force more airflow to the registers upstairs. Another possible solution is a furnace equipped with a variable speed blower motor.

These furnaces are designed to overcome airflow problems in a home, thus keeping the airflow steady throughout the entire house. These types of furnaces can also save considerable amounts of money in operating costs. How can I make sure that my HVAC system is safe to operate? Always have your system checked annually to make sure that the unit is safe. In many cases, tiny cracks or perforations in the heat exchanger occur. If your furnace is burning inefficiently or incompletely, carbon monoxide can escape and fill the house causing serious health problems and/or death to those inside.  Why not sign up for RHR’s Preventive Maintenance Program?  You will not only save money over regular service calls, but you can have peace of mind knowing that your air conditioning unit is being properly maintained.  We will even handle the yearly reminder for you.  Click here for more details about our Preventive Maintenance Plan. Should I cover my outdoor air conditioning unit during the winter?

Any cover, however, must be removed before the start of operations the following Spring. Can I turn off the power to my central air conditioning system during the winter months? There should be a disconnect in your panel box or at the outside unit. By turning it off over the winter, you will save energy. However, when you turn it on again in the spring or summer, do it at least 24 hours before turning on the cooling unit. Doing this will give the oil time to warm and lubricate the essential parts upon startup. How does an air conditioning system actually work to cool the air in my home? An air conditioning system consists of 2 parts: an outdoor unit (where liquid refrigerant is contained) and an indoor coil (where the refrigerant is pumped into). As the air moves across the air conditioning coil, the refrigerant removes the heat and moisture from the air by condensing it on the cold surface of the coil. Thus, an air conditioner not only cools, but also dehumidifies, the air. Troubleshooting & Repairing the Nissan Xterra Air Conditioning

An awesome member of our community made this guide. It is not managed by iFixit staff. The 2000 Xterra's Air Conditioning is sometimes cool but may not work other times. The Air Conditioning System will get cold when the Compressor Clutch is engaged but the clutch quickly quits and just blows semi cool to warm air. One possible cause of this symptom is that the Thermistor may be defective. Here is how to troubleshoot and replace the thermistor. The Thermistor connector is located below the glove box. You can see the white connector hanging out from under the dash. The purpose of the Thermistor is to keep the Evaporator from freezing. It does this by measuring the temperature and turning off the Compressor when the Evaporator gets below approx. 40 degrees F allowing the Evaporator to defrost. Locate your Air Conditioning Compressor. The clutch is the center area. If the clutch is engaged the center area will be turning. It will be turned off by the Thermistor to prevent the Evaporator from Freezing.

Here are the tools that you'll need to complete this guide. Test the thermistor by turning the Engine ON and the Air Conditioner ON. Using a Voltmeter (set to DC Volts), the Green/Orange wire will have battery voltage (around 13.5vdc) from fuse #29 in the under hood fuse box. The Blue wire will have battery ground from the AC control assembly. The most important wire is the Blue/Black wire. The Voltmeter will show less than .5 volts with the thermistor on (temperature above 45 degrees F). It will show a nominal 4-5 volts with the thermistor off (temperature below 40 degrees F). During inital operation, the temperature at the evaporator will be above 45 degrees and the Voltmeter should read less than .5 volts. When the temperature of the evaporator is below 40 degrees F, the Voltmeter will read 4-5 volts which turns the Air Conditioner Compressor OFF. This keeps the Evaporator from freezing. If your Thermistor is reading 4-5 volts when you first turn the AC on then your Thermistor is defective and needs to be replaced.

Replacing the Thermistor requires removal of the glove box. Remove the four upper screws and the two lower screws as indicated. Using a philips screwdriver, remove three screws. (as indicated by the orange circles) Using a 10mm socket, remove four bolts (as indicated by the blue squares) The two on the right are easy to see but the two on the left are difficult to see and are behind structure. Here's were it can get tricky. Of course the correct way to replace this is to completely evacuate the system and remove the evaporator but with a little ingenuity you can have it replaced in 10 minutes. Open the evaporate shell by splitting the halves. I used a spring clamp, backwards, to help me hold the halves open. Using a long pair of needle nose pliers, gently work the Thermistor out of the evaporate fins. I purchased a new Thermistor for $52 at the dealership. Install the new thermistor by using the Long Needle Nose Pliers to insert into the evaporator fins.
