Ice/water dispenser --stays on for 4 seconds after removing glass

Assuming you followed the water line installation directions and you have water available to your new refrigerator/freezer here is the rest of the "priming" info you requested. (basically it tells you how to run a bunch of water through the system by filling cups or glasses to remove any debris and/or air...

Automatic Ice & Water Dispenser
Priming the Water Supply System
1. Begin filling the tank by pressing and holding a drinking glass against the water dispenser paddle. 2. Keep the glass in this position until water comes out of the dispenser. It may take about 1½ minutes. 3. Continue dispensing water for about three minutes to flush the system and plumbing connections of any impurities (stopping to empty the glass as necessary).
Ice Maker Operation & Care After the refrigerator is installed properly and has cooled for several hours, the ice maker can produce ice within 24 hours. The ice maker will fill the ice bin from the rear. You must dispense some ice to force the ice forward in the bin. This will allow the bin to fill completely.
Turning the Fresh Food Ice Maker On and Off Ice production is controlled by the ice maker's On/Off icon on the control panel. Press and hold the "Ice Off" icon for three seconds to turn the ice maker "ON" or "OFF". The ice maker is turned off when the LED above the "Ice Off" icon is illuminated.
Using the Ice Maker after Installation Before making ice for the first time, be sure to prime the water supply system. Air in new plumbing lines can result in two or three empty ice maker cycles. Furthermore, if the system is not flushed, the first ice cubes may be discolored or have an odd flavor.
CAUTION
For proper dispenser operation, recommended water supply pressure should fall between 30 psi and 100 psi. Excessive pressure may cause water filter to malfunction.
NOTE The water dispenser has a built-in device that shuts off the water flow after three minutes of continuous use. To reset this shutoff device, simply release the dispenser paddle.
IMPORTANT On occasion, unusually small ice cubes may be noticed in the bucket or in dispensed ice. This could occur in normal operation of the ice maker. If you start seeing these more frequently, it may be an indication of low water pressure or the water filter needs to be replaced. As the water filter nears the end of its useful life and becomes clogged with particles, less water is delivered to the ice maker during each cycle. Remember, if it's been six months or longer since you last changed your water filter, replace the water filter with a new one. Poor quality household water may require the filter to be changed more frequently.
IMPORTANT Your ice maker is turned on at the factory so it can work as soon as you install your refrigerator. If you cannot connect a water supply, set the ice maker's On/Off icon to Off and turn off the water supply valve; otherwise, the ice maker's fill valve may make a loud chattering noise when it attempts to operate without water.
Hope this helps. Randy

Can you provide a make & model # for the unit?

Hello,

The filter status display will help you know when to change your
water filter. When the display reads 10%, order a new filter. It is
recommended that you replace the filter when the display reads 10% OR when water flow to your water dispenser or ice maker decreases.

The filter should be replaced at least every 6 months depending on your water quality and usage.

Step 2
Press the eject button to release the filter from the base grille.

Step 3
Pull the filter straight out.

Step 4

Turn the cap counterclockwise to remove it from the filter. IMPORTANT: Do not discard the cap. It is part of your refrigerator. Keep the cap to use with the replacement filter.

Step 5
Align the ridge on the cap with the arrow on the new filter and
turn the cap until it snaps into place.

Step 6
Remove the protective covers from the O-rings. Be sure the O-rings are still in place after the covers are removed.

Step 7
Push the filter into the base grille. The eject button will pop back out when the filter is fully engaged.

Step 8
Flush the water system. Use a sturdy cup or glass. Depress and hold the
water dispenser lever for 5 seconds, then release it for 5 seconds. Repeat this process until water begins to flow. Once water begins to flow, continue depressing and releasing the dispenser lever. Hold down for 5 seconds and then release for 5 seconds. Do this on/off process for about 2 minutes. This will flush air from the filter and water dispensing system.


Take care......

Does it make ice? If it makes Ice, then you have water to unit. If No Ice and No Water, check water supply. Otherwise, you could have a bad water valve. Remove valve and the line coming off of valve to water reservoir try to dispense water and if valve is good you should have water coming from valve. (have a bucket or bowl handy to catch water).

Remove the ice bucket/container from inside the freezer compartment. Examine underneath at the front of the container to see if ice cubes are lodged between the metal blades. If cubes are caught in this area, they will prevent ice from dropping into the glass/cup.

change the microswitch

I had this problem with a similar refrigerator. The problem was the slide switch burns itself especially if you slide it from ice to water while holding the glass in to get ice and water into your glass. Better to slide it to ice, press the glass in to get ice, release the glass to stop the ice, slide the switch to water, then press the glass in again to get water. I "fixed" mine by removing the control panel and soldering some of the connections on the slide switch together so that we now have no crushed ice function, but the ice cubes work again. You can also replace the circuit board in the control panel to restore it to like-new operation. I could not find a place to order just the slide switch.

Not sure if this is the same problem with your unit, but sounds the same.

water dispenser continues to run too long after removing glass

possible circiut board.

It is possible. When you put hit your glass against the paddle to you hear the switch click? And can you still select between water, cubed, and crushed ice? Also does the light by your glass come on when you but your glass against the paddle?

When you put your glass on the paddle it pushes in a microswitch. That microswitch will power the light if it is working and also sends power to the board you are talking about to dispense ice or water depending on what you have selected.
