My Kenmore front loader sometimes fills with warm water on cold setting.

There might be an issue with the house water supply for the washing machine that needs to be repaired or replaced or the hose could be clogged or needs to be replaced.

Since U get warm water that tells you that the cold and hot water solenoids are both operating. Ergo the anomaly has to be with the device that controls temperature.

Your mixer valve is for sure bad..

yes you should have both hot and cold hooked up. if that is not possible splice the line you have and y it into both inlets. thats not the best way to do it but will solve the imediate problem.

You need to replace your cold water, inlet valve.

Unplug the machine from the power source. Disconnect cold water hose. remove the top cover of the machine. You will see the cold inlet valve/solenoide where the hose fits.

Take note of where the wiring goes. You can get the part from your appliance parts outlet.

Refit, and you should be right to go.

Good Luck.

The temperature control board is bad . Pt # 388246

The water fill valve - The water fill valve is a mechanical and electrical part, the coils on the valve need electricity to mechanically open the valve to allow the water to flow into the washer....myth....the washer pumps water into itself...no, it does not. The fill valve opens and the house water pressure pushes the water into the washing machine.
No cold water or no hot water - The fill valve has two coils, one for the hot water and one for the cold water. It is possible that one of the coils can fail and you loose that filling ability. If the cold water coil quits, the hot will still work and during warm fill you will get hot water only and during a cold fill you will get no water at all. If the hot coils quits, you will still have cold water fill, cold water only on a warm setting and no water on a hot fill setting.

If the hot coils quits, you will still have cold water fill, cold water only on a warm setting and no water on a hot fill setting. You can test a fill valve live for 120 volts, power to a fill valve coil and no fill = a bad fill valve. You can also test the coils for continuity, no continuity = a bad fill valve. Some Maytag washers have a fuse in the fill valve circuit, if this fuse let go the washer will not fill. Fill valves can also from time to time stick open and not stop filling. If you have to shut off the fill valves to stop the water from filling in the washer, you have a bad fill valve and you will have to replace it.

kenmore washer hot or cold fills ok but will not fill with warm but only cold water

first of all check to be sure the cold water vavle is opened all the way, then checked for a kinked hose. if both of those is ok there is a screen in the valve that catches trash in the water. remove the hose from the machine (and possibly from the supply valve )and check to make sure there are no obstructions.

if all that checks okyou have a bad water fill valve. you can order the valve from sears and it is very easy to replace.

good luck..

Yes patrick you can try removing the cold hose from the washer, look inside the valve for a metal screen. If it has sediment blocking it remove screen, clean it and reinstall. If still no water replace inlet valve.
