Why does drain pan overflow? How is water in pan suppose to go away before overflowing?

IS THE EVAPORATER FAN RUNNING

It's not unusual for a refrigerator to drip a little water on the floor after you replace the water filter-air trapped in the water dispenser system can make the water dispenser drip enough to overflow the drip tray below the dispenser. You can fix it by streaming a gallon or two of water through the dispenser to eliminate the trapped air.
If water drips on the floor from the back of the refrigerator, a leaking water inlet valve or cracked water system tubing could be the cause. A clogged or cracked defrost drain tube could also cause the leak. Defrost condensate water collects in the drain pan at the bottom of the refrigerator so a cracked or overflowing drain pan can also cause water to drip on the floor behind the refrigerator. Check the drain pan for cracks and clean out any foreign objects that may be inside the drain pan.
Excessive frost caused by a leaking door seal can also cause the defrost drain pan to overflow. Check the door gaskets and replace them if damaged.

Hi,

What kind of unit do you have? Its possible depending on the manufacture that a water line is the cause as it drips water into the pan causes the overflowing of the drain pan. Look for cracks in all the water line under the unit and you may have to remove the back and the water valve to see it. Good luck

on most fridges, you should be able to empty drain pan. Remove grill on bottom at the floor, and see if pan will slide out. Good-Day!

If the drain pan is overflowing, they are made to catch drips. But if you overfill the glasses a few times a day the pan will overflow because there is no drain for the pan. You have to soak it up with a sponge if this is the case. If its leaking then there is a solenoid in the back of the refrigerator that is sticking, if so remove the solenoid valve wire connectors, the water lines and the solenoid valve water control valve and replace. Local appliance dealer should have one for about $60.00 or so. They make a universal solenoid water valve that fits most refrigerators. Good luck I hope this solves your problem.

Most Viking models have overflow safety feature that turns the dishwasher into drain mode. The idea is to remove overflow water from the bottom pan. Check the pan behind kick toe panel for water, remove the water and check for leaks. If no water check overflow switch somewhere in the pan, it maybe stuck. Good luck

remove the back panel inside the freezer,then defrost the pan,then take a length of stiff wire and clear out the drain line from there down to the pan in the lower area near the compressor,as theres probably lime,mold growth build up in the drain line plugging the hose restricting draining of defrost water

The rubber seal on the water filter is bad . Replace the filter in the bottom kick plate . When the filter goes bad , water will drip into the drain pan , causing it to overflow .

Maybe your machine has a leaky door, letting moist air inside. Make sure your compressor area is lint free. The heat from the compressor is supposed to evaporate that water. Make sure the pan is exactly in the right place, level, not cracked.

sounds like you have a clogged defrost drain tube. removing back panel of freezer will give you acess to drain trough, melt away the ice with a hair dryer, youll find a drain hole under there somwhere,pouring boiling water down the drain will clear it pretty quickly( i use a steam machine purchased from the infomercials works awesome, after you clear it and all water drain down tube wrap a piece of solid copper wirearound the heater( black calrod heater right above the drain trough) and stick it in the whole maybe an inch or so. now everythime the heater comes on to defrost it will prevent the hole from freezing over
