Shoot door (flap) for ice maker wont stay closed causing frost

Does you ice dispenser serve ice through the door? If yes, then It's likely that room air is entering your freezer through the ice exit, and condensing as ice on your ice maker.

It's a very common problem; The flap isn't sealing tightly after ice is delivered through the chute. Clean you ice maker, removing all the ice, and then stuff the exit chute with plastic grocery bags. The bags will force the flap tight against the chute, and add a layer of insulation from room air. Keep an eye on ice development, for a few days, and if you're confident you've found the problem, order a replacement ice door.

only use ice from the ice maker, some frost is normal, but , lower temp in freezer

Look into the dispensor , and see if the door flap is closing , or letting warm air in which will cause the frost buildup . If not closing completely , remove the top cover on the freezer door hinge , and unplug the plug . This will remove power to the door . Use a small screwdriver , and insert under the freezer door dispensor control board , and pry outward . Remove the 3 plugs on the board . Next , remove the 4 screws holding the white dispensor cover , and slide outward . At the top right , you will see a solenoid and plunger , which control the door flap . Usually , this plunger rusts on the solenoid . Replace both , the solenoid and plunger ( come together in kit ) Pt # WR62X10055 . Re-assemble in reverse .

The ice dispensor flap is not closing completely , causing the frost in the inside shoot and on the bottom of the dispensor . Sometimes caused by a broken ice guide ( clear piece attached to the arm that activates the dispensor on the door ) it hits against the flap , not letting it close . Model number would have helped more .

Sounds like your saying that the ice dispensor flap is not closing completely which will cause frost on the inside shoot and on the ice bucket . Could be because of a broken guide ( clear plastic piece attached to the ice dispensor arm ) . Need brand and model number to help .

Sounds like your freezer is pulling outside air into the freezer from the dispenser door or around the door seals. This could be a defrost problem beginning as this is moisture remaining inside the freezer compartment and not being taken out during defrost. So it may be a good idea to look into the back of the freezer and see if there is frost forming also on the rear wall. If yes you will need to manually defrost by unplugging the refrigerator and removing the rear panel in the back of freezer to expose the evaporator coil. If frozen over I want you to defrost with a hair dryer until we can have a look at the defrost heater below these coils. The heater in your model PSS26MRSS has glass around the heating elements and will be easy to see if the element is burned out. If burned out the defrost heater part number WR51X10055 and the defrost thermostat part number WR50X10068 should be replaced. Let me know if you are ready to begin or if this is helpful. If by chance these 2 parts look OK then we will need to look over the main control board for burn marks or signs of heat damage. I'll be here if you need me Thanks, Sea Breeze

With this information , it sounds like the flap that lets the ice thru the door , is not closing completely , letting the fan in freezer , pull in the outside air .

You have a bad dispensor flap solenoid . Frost due to flap not closing completely and ice will catch in the shoot .

Open the freezer door and look down the ice chute while you shine a flashlite up the dispenser cute from the outside. If you see light around the chute door, it needs to be replaced or something is wrong with the mechanism. The problem you describe is almost always air leakage around that flap.
Post back if you need more help.

Is the trap door flap closing properly where the ice comes through the door? If open, warm air would be coming in frosting and maybe iceing things up
