Brand: Whirlpool

Freezer evaporator has frosted. Evaporator fan ok. How is the defrost heater controlled?

The dispenser pump motor runs but it’s not measuring and adding the soap.
The blue soap dispenser is in it’s proper place. How do I check if the dispenser pump is pumping?
I’m referring to the w10842325 dispenser and pump assembly.
Could the hoses be clogged?
Please explain In as much detail as you can.
I notice when i run the diagnostics that though that small pump motor runs it doesn’t turn on the water valve. I suppose that the water it pumps into the dispenser comes through the mixing valve.

Hi,

The refrigerator is cooling but the freezer is not reaching the correct temperature (cooling but not freezing). There is ice build up on the right side of the evaporator coil (not on the evaporator itself). Both fans are running (condenser and evaporator).

To whom it may concern,
I have a whirlpool WRF757SDEM refrigerator that recently has a loud noise coming that appears to be coming from the top section. Last year I replaced the evaporator fan and thermostat as the unit has frozen up and stopped cooling. After that fan was replaced the unit was very quit and running normally.
Recently ( past 3 days) it has gotten very loud at times with a slight vibration. At times, the sound is very loud, but then it gets quieter; almost to normal levels.
The top unit is cold and maintains temperature, there isn’t any issue making ice and everything is cold and frozen in the freezer.
I am wondering if its an issue with the evaporator fan and if that needs to be replaced again.
Any and all assistance would be greatly appreciated.
Kindest regards,
Kris
