I have an Amana Side by Side Refrigerator with an icemaker and water dispenser. I don't have a water line to hook up to the refrigerator. Is there an on/off switch for the icemaker?

If you don't get water at the valve and it has power it is likely clogged. Take it apart and find most likely a part where the rubber has softened and clogged a hole that is supposed to open up when the valve is triggered. On mine it was at the bottom of a little metal pole that the rubber was bad. Clear the clogged hole and replace the bad seal and you should now have water.

Refrig. cant work unless the freezer is working ...all cold in produced in freezer and circulated to refrig. check freezer for frost build up and if fan is blowing, check condenser, make sure its clean, and fan blowing, check vents in refrig. make sure no blockage, controls should be in the middle setting, check make sure compressor is running

sounds like a leak where your incoming water line hooks to the water valves might just need to tighten the coupling or a mouse has chewed through one or both of the lines access the lines on the back and watch while some one gets water out the door to locate the leak

depending on the brand and the style, locate the filter and change it out. Please note that you must empty out the remaining water from the refrigerator cause if you don't, when you change out the filter you might get the same taste for a while until all the remaining water is replaced by freash water.

Good day,
A step by step procedure should resolve your problem. If the dispenser is working, you can skip that step.

First step is to take a small paper cup of water and fill the cavity until it is near full. With the ice maker turned on, close freezer door and wait 3 hours to see if it harvests. If not, the ice maker is bad, and must be replaced. If the cubes harvest then.......
Three possibilities.
1. The water supply from the house is not delivering water to the water valve. Shut off the house at the meter, disconnect the line going to the water valve, and with the line pointed into a bucket, have someone turn the valve back on for a 15 second count. The water should come out smartly. If not, the line and it's fittings will have to be replaced.
2. The fill tube from the back of the machine that feeds water into the back of the ice maker is frozen up. You will have to remove the ice maker to visually inspect that tube. If blocked, it needs to be defrosted, but use caution. Too much heat too fast will start to melt plastic and vinyl parts you don't want melted.
If this is the case, then once cleaned out, you will have to change the water valve located in the back bottom rear of the machine because it is leaking during the off cycle.
3. If everything checks O.K. up to this point, you will have to purchase and install a new water valve, and install it.
P.S. Under very rare occasions the electric circuity in the ice maker will fail to send a signal to the water valve. Although rare, it can happen, in which case the best option is to replace the ice maker and water valve.
