Re: Ice maker not working
Lynn,
Am I safe to assume that you are talking about an ice-maker that is in the refrigerator and not a stand alone one? I will base my answer on that belief.
Have you checked to see if the tray has ice in it? If it does not, then you probably are not getting water to the tray, but a very common cause of an ice-maker to quit is that the unit has frozen up and it needs to be defrosted. I suggest that you first check to see if there is ice in it, and if it may be perhaps, over full. If it is, defrost the refrigerator and use a towel or something cloth to soak up the water from the tray so that it will start out, empty. That is the reset condition of the ice-maker.
It you find that the tray is empty and has no water or ice in it, then it is time to check farther. The first thing is to consider why there is no water. I highly doubt that you have a broken water line because you would probably see water leaking out of the outside access panel Even so, remove the rear panel and look to see if there are any signs of water to indicate a leak. If not, next try to see why no water?
In most RV refrigerators the water line to the ice maker is directly inside the access panel and usually comes up through the floor of the space that the refrigerator occupies. Locate that water line and check to see if there is not a manual shut-off valve in it. Check and make sure that it is open. Assuming that it is, the next thing is to check for water flow. I would shut that valve and then trace the line to where it joins the solenoid controlled valve which supplies water to the ice maker. With the shut-off closed, disconnect the line from the inlet to the solenoid valve and point the line outside of the RV. Next open that shut-off which you closed before to see if water comes out of it. Most likely it will but if not you have found the problem.
If water does come thorough the supply line, the next step is to check the solenoid valve. The first thing is to lift the leads from the connections to that valve and use an ohm meter to see if the coil is good. If it is, there should be very low resistance through the coil, probably about 5 ohms or less. While you look at it, check to see what voltage the coil is. Most of them are 120V, but it could be 12V so make sure. Once you know, disconnect the water line from that valve to the freezer so that the outlet will be visible. With water supply connected and turned on, use jumpers to supply power to the solenoid for a few seconds to see if water comes out. If the valve is good, you will get water. You should also feel it snap open and usually you can hear it as well. The last thing to check is to try blowing air through the water line from the valve up to the ice tray.
Somewhere in this you should discover where the problem is.
If you will tell us what make and model of refrigerator and ice maker you have I'll look to my service manuals to see if I can give any further advice.
