Pressure relief port over heating

the outside is the condenser exchanging heat to the air and indicates that the system is working
you only have a problem if the inside is not freezing.
constantly running can be that the setting is too low numbers i -20 with 20 the coldest and the colder the setting the more loss through the insulation so the motor keeps running
the door or lid open or too frequently being opened
the inside iced up and needs defrosting
The light could simply be a power on light

The condensing coils are embedded in the walls of the freezer. The freezer uses the wall as a heat sink. This allows the freezer to dissipate the heat that has been pulled from inside the freezer to the area outside of the freezer.

Hello, their are heat coils in the doors, their maybe a issue with the door heat circuit controls.

sounds most likely didn't get a good fill in the foaming machine the fills the door cavities wiht insulation. I've been in a refigerator plant and seen it happen. They are supposed to be checked. Tap various places around the outside of the door to see if there is a hollow sound. It could just be around the outside edges of the door unless the whole door is cold.

The hot sides is normal, this is how they expel the heat from inside the freezer, sometimes it may help to use a fan to help cool. Also make sure there is about 12" of room around all sides of the freezer .

If there is a short circuit, the circuit breaker protection in your house wiring would trip (Open the electrical circuit path).

It is normal for the condenser, which is on the outside of the appliance to be hot because it is transfering the heat from inside the freezer cabinet to the ambient air outside the cabinet. Make sure that you give the appliance enough space all around the hot condenser so that it can transfer its heat to the surrounding air efficiently.

P.S. Some freezer designs integrate the condenser coils into the metal cabinet, thus the hot side panels.

A side door heater is already defective.
It has heating element, it is there to dry any moisture build up around freezer door.
When it become defective, moisture or condensation occur, hence moisture is there.
Causing it to rust build or develope on the metal of the freezer.
Rust weaken the metal and soon tearing it.
Have it check by a service technician before it getting worse.
Good luck.

When you open the door and then close it they will cause a vacuum. some freezers have a pressure relief. if the heater stops working on the relief it will cause this.

Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer.

the coils that deliver the cold air are building up condensation. anything that gets cold in the outside should be insulated so as to reduce condensation. hope this helps
