I have a frigidaire side/side model #PHSC39EGSS0. There is frost build up in the ice dispenser chute, and jut below the inside ice dispenser.

I need you to confirm your model number. Is MZD2665HE correct? The problem is very likely a broken 12565502 Dispenser Door Spring or more providing you have the correct model number. There may be a kit if the model number is different.Thanks, John Tripp Appliance 911

this can be of some help.. http://techie-doc.blogspot.com/2010/09/fixing-refrigerator-problem-frosting-in.html

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

I had the same problem. After 6 months I contacted Frigidaire about it. They made arrangements with a local factory service repairman. Be sure you have your model and S/N available. The repairman came to my home, verified the problem and returned a week later and installed the replacement door dispenser. Problem solved.

This sounds like your ice may be melting and freezing around the chute. You may need to replace that rubber gasket on the chute. Otherwise, if you use a lot of crushed ice, that will build up badly on the chute and you can manually clean that off. I hope this helps you!

Sounds like the dispensor flap is not closing completely , pulling outside air in . Using a flashlight on the outside of the flap , look inside to see if any light is visible . If so , then the ice flap plunger and solenoid will have to be replaced . Also , excessive crushed ice can also cause frosting .

you need to replca the dispensor door assembly

Oddly enough, the problem is with your ice dispenser. What happens is that the door at the bottom of the ice chute is probably not sealed. This is likely because there is a solenoid that is supposed to hold that door open when you push your cup against the dispenser arm, and THEN, close it again when you release. If the chute door is not sealed, warmer, moist air from outside the refridgerator will be canstantly drawn up the chute where the moisture will freeze as frost. Gradually, this frost builds up in the chute until there is no longer enough room foir the ice to fall. You can usually look up at the chute from outside and see that the door is not sealed. In my case, I left it unsealed because the door would not open to let the ice out. It took me about 3 months to figure out that this was causing my frost-clogging problem. The solution is to replace the solenoid that is supposed to open and close the chuite door. If you remove the despenser panel, you will see that this solenoid is probably all rusted up and not working.

Suddenly having the same problem. Any solution?

first check would be to see if the flapper door is closing all the way in the dispenser area. best way is to remove the ice bucket and shine a flashlight from the front up into the disp door area and look for light around the door from inside the chute.

another check would be to make sure the door delay mechanism is connected an not allowing the dispenser door to close to fast trapping a cubes in the door and causing an air leak in the chute..

Keep in mind if you use alot of crushed ice frost build up is faster than with just cubed.
