Weird (Pressure Release) Noise After The Door Has Been Closed

Just bought this freezer used from an individual. It is cooling great, but when you open the door and close it, it makes a strange noise and I'm not sure if it is something to be concerned about or if it is normal.
Why would the freezer make a noise like pressure is being released when you close the door. It almost sounds like it is decompressing air after it has been opened.

Thanks!

The freezer being closed up tight and so cold can create a negative pressure inside. This negative pressure will cause the door to be very hard to open and could pull the door closed too quickly. Most manufactures today use small air valves the open and release as the door is being opened and closed. They are most often found on the bottom of the door itself or sometimes in the cabinet behind the back wall.

The noise is perfectly normal, my wife says it is there to alarm her when I am eating too many ice cream bars.....

Testimonial: "Thank you so much for the reply. It was actually my ex who purchased the freezer and he said he laid down on the floor and listened to pinpoint where the noise was coming from. He said he found two valves on the door and apparently what you mentioned is exactly what the noise is. Good to know it is normal and apparently he got a great deal on the freezer. It was really clean and he purchased it for $100. Thanks again for your help. I rated you the best rating I could. You deserve another ice cream bar - go for it:) Have a good one!"

Samsung refrigerator loud noise


if the fan is still running when you open the door , the I would be leaving that idea as a last resort
try this
get 2 taper door chocks and put one either side at the back of the fridge
push the cabinet sideways and slip one chock in a bit then do the other side
many noises are from the bottom plate that the compressor is mounted on from tapping on the floor and lifting it a bit stops the noise
the same as when you open the door the pressure on that plate is removed and so it stops hitting the floor

ICE BUILD UP ON INSIDE BACK OF FREEZER.


The air in the freezer is circulated by a fan, there are a number of possibilities
1. Is the internal fan running, this may be switched by the door opening, to test push the small switch on the door frame ( if fitted). If the fan is running go to
2. If the fan is running can you feel air coming out of the bottom of the duct inside at the bottom.
3. If there is no air coming out of the duct the duct is possibly blocked with ice, or the cooling coil at the top is iced up.
4. If there is no air flow then the best and quickest option is to empty the freezer, store your goods elsewhere, switch it off, use a wedge to keep the door partly open and leave off for at least 24 hours. You may find a large pool of water on the floor after this and you will also need to dry out the inside of the cabinet.

Icing of this type is caused by
1. Door not being closed properly, door misaligned or faulty door seals.
2. Putting "hot" product (over 2deg C / 34 deg f) into the freezer.
3. Not covering or sealing product being stored in the freezer.
4. Defrost timing not working (ask your service guy) for this and the rest I'm afraid
5. Defrost heater not working
6. Blocked condensate drain
7. Faulty thermostat, keeps on cooling

Hope this helps

Left door open, closed next day, but only blowing cool air now


You will need to turn the unit off and let it completely unthaw. There is frost that builds up in the ducts and behind the panels when the door is left open that will cause the unit to not cool or circulate where needed.

My kenmore freezer is making a lous noise that


Is it still cooling ok - or is it going a bit weird ?

It could be the flow control solenoid - that affects where the gas goes - or the compresor motor (big black thing).

If it does not cool at all - it will need a new run capacitor on the compressor.
If it seems to cool ok - but sometimes too much - then suspect the solenoid coil / control for this.

Neither are that expensive.

My maytag Wide by Side refrigerator started making this buzzing noise coming from the freezer section every few minutes and now it no longer cools.


It is possible that the door was not closed tighly, so the humidity built up in the duct line and the low temperature from the freezer make it turned into ice causing the clogging. The Buzzing noise turns on due to the sensorsomewhre along the disigne path. Unplug the fridge for a day and a half so the the ice in the duct line could melt down then when you turn on the sensor won't turn on the buzzing any more. Good luck.

Inadequate cooling on walk in freezer


YES GOOD ADVISE . ALWAYS START WITH THE BASICS. IS EVAPORATOR COIL CLEAN AND CLEAR? ALL EVAP FANS RUNNING? DRAIN PAN CLEAR? IS STAT CALLING FOR COOL? IS OUTDOOR COND COIL CLEAN? IS OUTRDOOR FAN RUNNING WITH NO PLAY IN BUSHING? DO RUN AND START CAPS TEST GOOD? DOES CONTACTOR LOOK GOOD? THEN TRY TO CATCH UNIT WHEN TEMP IS ABOVE DESIRED SETTING. FIRST TEST STAT. IS IT OPEN OR CLOSED? IF BOX IS HOT AND ITS OPEN THEN PROBLEM IS STAT. IF STAT IS CLOSED AND OUTDOOR FAN IS NOT RUNNING THEN COMPRESSOR PROBABLY OVERHEATING WHEN FAN QUITS. CHECK FOR VOLTS TO FAN GOT VOLTS? FAN IS BAD. NO VOLTS? TRACK BACK TO SOURCE OF POWER ( CONTACTOR) AN R22 BOX AT 52 PRESS IS NOT TO BAD ON START UP ON A HOT BOX BUT COULD BE HIGH ON 502 408 OR R12 STUFF TYPE OF REF IS DEFINITELY IMPORTANT. GOOD LUCK

Door


If the door is not sealing because of frost build up or product blocking it it won't make the noise. Is it still cooling ok? If you haven't defrosted it you might do this now. Is it in a cold location, i.e. unheated garage up north? This can cause it also. Check the door and the cooling first if it's not right I would call for service. You should have a one year warrany.
