Delfield Refrigerator/Freezer Condensation forming outside door seals

This is likely condensation that occurs when the surface of the door frame (the part the gaskets close against) drops below dew point. Dew point is the temperature at which moisture condenses and varies from day to day depending on temperature and humidity. Refrigerators have a "dew point compensator" that is either an electric mullion heater or a "Yoder" loop made up of a part of the condensor coil. Both supply a small amount of heat that keeps the surfaces above dew point. Be certain your box doesn't have a switch for "Energy Saver". If it does, then turn off the energy saver. This switch controls the mullion heater. Turning the energy saver off - and the mullion heater on - will prevent more moisture from forming. It will NOT remove moisture already there, just wipe that off first. Other external causes could be a HVAC duct blowing cold air on the refrigerator, a refrigerator/freezer door left slightly ajar or (the worst case) a separated heater inside the case. (On a foamed in place cabinet this is not repairable.)

Hello,
A refrigerator not cold enough is a hassle, because you are at risk of spoiling the foods you store in there. Most often, this problem is caused by something easy to fix. 1. Faulty Door Gaskets
The door gaskets in a refrigerator ensure a sealed closure every time you shut the door. Torn or loose gaskets on the door of the refrigerator can result in a leak in the cold air. As a result, the refrigerator is warmer. Repetitive and frequent opening and closing of the refrigerator is also a possible cause, because the warm air from outside replaces the cold air in the refrigerator every time you open it. 2. Dirty Condenser Coils
Dirty condenser coils can result in improper functioning of the refrigerator. These coils are located on the back or the underside of refrigerators. If you find this to be the cause of the problem, unplug the refrigerator before you attempt any cleaning. 3. Frost-free Feature not Working
If the frost-free feature fails, it causes a buildup of frost around the evaporator coils in the freezer. This causes a malfunctioning of the evaporator fan that blows cold air around. The fan can also be damaged if it hits the frost. 4. Faulty or Incorrect Temperature Control
A faulty thermostat can lead to a refrigerator that is not maintaining the desired coldness. Check for this problem and also ensure that the temperature is set to the correct level. Normally, refrigerators are set to a temperature of about 0°C, whereas the freezer sections are around -17°C. 5. Inadequate Air Flow inside Refrigerator
A refrigerator that is loaded with too many food items can fail to maintain an adequate level of coolness across all the items kept in it. The surface items tend to be colder, and the items underneath do not become as cold. A refrigerator that has very few items in it can also fail to function efficiently. Try to ensure that your refrigerator has enough food in it at all times, but is not so loaded that the air flow gets constricted. 6. Vents between Freezer and Refrigerator Clogged
The vents between the freezer and refrigerating section blow cold air from the freezer across to the refrigerator. If these vents are clogged with ice, the air is blocked and the refrigerator does not cool down. If this is the case, you can unplug the refrigerator, wait for the ice to melt and then connect it back to the power supply. 7. Faulty Door Switch
The door switch is found on the bottom of refrigerator doors. It turns off the light in the refrigerator and resumes cooling action when you close the door. If this switch is not functioning properly, the refrigerator will not be cold and it will also be affected by the heat of the interior light. 8. Refrigerant Leak
A refrigerant leak is very unlikely. This problem can cause malfunctioning of your refrigerator. If you suspect this to be the cause, contact a service technician.
Hope this will help out....

Hello, Thank You for using FixYa. I will be helping you today. This is usually a sign that the door gasket is leaking warm air into the unit. Check door gasket
Thank You and please rate my answer if it was helpful..

Hello,

We specialize in cooler/freezer gaskets and have a custom made gasket option that would be helpful if you cannot locate the model and serial on your unit. It's a simple process at coolergaskets.com

Step 1: visit our custom made gaskets page HERE and identify the gasket profile material that best matches your existing gaskets. Common Delfield profiles: 165, 221, 494, 548, 770, 802, 891, and 967

Note: If you have a hard time with this we offer a $1 gasket sample ring.

Step 2: Input the outside edge dimensions you need your gasket to be (length and width) and how many sides it has (3 sided gaskets are most common for walk-in coolers/freezers, You will want precise measurements. Here's our " How to measure your gasket" video.

Step 3: Select the quantity you want and add that gasket to your cart where you will be able to proceed to check out there. Then relax because your gasket is in good hands!

I hope this helps!

you might need new door seal :
Refrigerator gasket Number: 67003548 70$ and see if it EZ to replace...good luck

try using a hair dryer on the door seal to get it to take proper shape. I was a service tech for years, and this worked every time.

A faulty door gasket will definitely cause excessive condensate and running time. There is also a door heating system which is from heated refrigerant circulating around the area where door gasket meets cabinet. You should be able to feel a certain amount of warmth in this area. If not there could be condensation again from cold leaking out of the gasket and being formed on the actual cabinet.

sounds like you have a gap in the door seal, which results in condensation forming inside unit. Use a blow dryer to heat the seal around the door and ensure that the fit is tight.

Look at your door gaskets. If they ain't kosher then excessive humidity will build into the frig.

I have the same problem with my frig in the basement. I get condensation and resulting mold on the top outer surface and related areas. This is from the surface being cold, with resulting outside moist air condensing on the cold surface. Best solution - spray/wipe the surface with a bleach and water solution, let it soak a few minutes, then wipe off with a rag. Add a drop of dishwasher soap to a mixture of roughly 4 parts water to one part bleach. Repeat if necessary. Do this as often as the problem seems to creep up again. Good luck!
