Re: Door gasket

Try putting vaseline on the gasket. You are not getting a good seal.

I have a Frigidaire freezer that is about 5 years old. I get ice build up inside the top of the door. The door appears to be closed.


My name is Peter. I am a retired field service refrigeration technician.

1.) Due you have the freezer in your garage? Freezers and refrigerators are not designed for the drastic temperature change through the seasons. If you had a service contract, your contract would be canceled.

2.) If you can run a piece of paper between the top door gasket and the freezer body you do not have a tight seal. Repair - Recondition the gasket. Wet the door gasket with water, with a hairy dryer heat the gasket while genteelly pulling the gasket out to expand with a spatula.

3.) If the gasket is good, then you are getting moisture either thru the top front of the unit or the top of the door.
a.) Inspect the liner where the ice build-up is. Are there cracks? Repair - Seal cracks with a good silicone adhesive.
b.) Inspect the upper door section and the front top of the freezer for possible leaks in the joints. Here again seal with adhesive.
c.) If the top of the door is expanded, then you have moisture in the door and need to replace the door. You will never get the moisture out of the insulating material.

Freezer door has mosture on the outside

You need to order and replace the door gasket. Also check and be sure there the hight adjustment is correct, meaning the door is centered on the opening and not off set to where it can seal.hope this helps

I am experiencing frost build up on the top part of the door as well as the top part of the inside of the freezer. all other areas are fine

You have an air leak. Usually right where you frost build up is, however since hot air rises, sometimes this leak can be anywhere. Make sure your door closes tightly and your gaskets are clean and making good contact. You may have to adjust the gasket, adjust the door, or replace the door gasket. If there is ice on the floor of the freezer, you have a plugged drain line. In very rare instances we have found, where the freon lines enter the freezer, in the back or under the freezer, missing or fallen refrigeration putty that seals around the lines. Good Luck, Appliance Specialists

Admiral upright freezer dripping water inside on top

I can help. Once we notice anything different from before we start becoming more aware of small variations. Regarding things on the top shelf warmer than on the bottom, this is always true because, "warm air rises and cold air falls". If you want the top shelf colder turn the thermostat to the next colder setting, always a good idea in the Summer season anyway.

Even though your gasket looks good, a ten year old gasket is not as pliable as a new one resulting in the moisture problem you describe. I would begin by applying a thin coating of vaseline to the gasket once a week for a month. This little trick of the trade will often work. If it doesn't improve the situation do replace the gasket.

Freezer door is accumulating frost inside it at the very top. Frost build up has been occcuring for 7to 10 days and we have been removing it periodically. Freezer purchased on 6-23-05. The gasket appears...

The gasket is not sealing correctly and is allowing warm air to meet cold air just below the seal.

Get someone with more skill to fit a new gasket , preferably one made by the original manufacturer , which should fit unlike some of the parts made by third party suppliers

Just defrosted my freezer and is akll frosted over

When you say it is frosted over, do you mean the interior of the freezer is frosted, or the evaporator coils?

A couple things to check for:

1. Is the door gasket making a good seal when you close the door? A good quick fix for a bad seal on the gasket is to rub a thin layer of Vaseline (the original jelly kind works best) on the rubber to help it stick and to fill any scratches that might be keeping it from sealing tightly.

2. Is the fan running on the inside of the freezer? The evaporator coil in the freezer needs a fan to blow air over the coils to keep them from freezing over. They don't run continuously, and on some units will turn off when the door is open, so try holding the door switch shut when you check.

3. Is the defrost cycle working? Frost-free freezers have a defrost cycle in which a small heater turns on to thaw any frost that has begun to form. To check the functionality of the heater and the defrost timer will probably require a visit from a technician... It would take a while to explain it here, but if check the first two and come up empty handed, post back. You will need a volt/ohm meter.

I would check the first two

Frost build up in a frost free freezer

It could be the door gasket. It could also be that the fridge needs a good defrosting. (especially if it is an older fridge)

When I bought my house I had the same problem with the fridge that came with the house. I assumed the previous owner had been defrosting it regularly, which he had not.

Eventually I decided to try a full defrost, and my fridge now works like new.

Ice build-up on the inside top of of freezer door

yea def , not normal, nor an acceptable amount of ice forming there( good pic). heres what i have been told to try and with good results
first make sure the door gasket is sealing all the way,(small gaps in ht emagnets at extreme corners) is common but with a little amount of "mortite"or "permagum can sometimes be insterted behind the corner of gasket to assist filling the void.
second a small amound of a white/clear silicone be applied to the outer perimtere of gasket, to minmize air movemnt from between gasket and door panel.
lastley in oyour second pic i see "frost free" written on a plastic air deflector. you can remove that with 3-4 screws on backside of it, and then reinstall with a small spacer so as the baffle now with sit with a 3/8in. gap between it and the top of the freezer liner.( a brass ferrel from the compression fitting of a plumbing fitting is just the right size)..... the theory behind this is to prevent the air from gatting "trapped" in the void created when the door closes-- air can now pass back and forth freely.
I hope this gives you some satisfaction if not I would advise another tech be sent who is willing to call for factore tech support( ths is where i got my info from)
