FREEZER FAN HOWELS AND STARTS AND STOP STARTS AND

Question edited for clarity, MAKER.
Question moved to Model Category.

Your fridge freezer has three fans.

The compressor evaporator fan cuts in and out as required to maintain temperature.

The fridge evaporator circulation fan runs to maintain an even temperature. It stops when to open the door and resumes when you close it and stops when the set temperature is reached as long as the compressor isn't running. If the compressor is running, the fan normally runs to prevent icing which happens slowly.

The freezer also has a fan, and that runs pretty much all the time unless target temperature is met and the compressor is not running. This fan runs when you open the door to stop the moist air from the room freezing on contact to the 0'F, -18'C evaporator fins. The fan keeps the air moving to deposit less frost.

It sounds like your is running normally except for the noise. Trace the noise and find it. The compressor fan has a Shark Paper fibre board cover and these often distort over time and touch the fan blades. That is the common cause. The less common cause is the internal fans pinging off built up ice that should have been removed during the defrost cycle.

Try defrosting compleat if continues need fan replaced

Check the rubber mounts under the compressor and look for any lines touching the sides of the cabinet. The gurgling and clunking are often normal. good luck. Roger

there is a loose connection at the rear of the freezer near or around the compressor unit , i strongly advise you to get a professional to look it.

Feel top of the compressor and tell me how hot after it has been running awhile. I need also that you advance the defrost timer=>. 216517400 Defrost Timer

clockwise slowly untill the compressor stops or starts. I need to make sure the timer is not stuck into defrost. I want you to leave the compressor off for up to 35 minutes. If the freezer compressor doesn't restart bt then simply again turn the timer clockwise slowly until it does and then stop turning. The defrost timer is location 23 in this photo HERE If you need to turn the defrost timer like this to restart the compressor then replace the defrost timer and this will resolve the freezing problem. If not we move to the defrost heater location 14 in the sme photo=> 216254600 Defrost Heater

I am going to stop here until I hear from you, Thanks Sea Breeze

Is it freezing properly to zero degrees F? Noise could be bearing in evaporator fan motor, or compressor itself.

Hello,
Check the temperature setting
Assure that there is enough room for air flow in the freezer or freezer
Check for air flow restrictions in vents
Test the temperature control
Clean the condensor coils
Check the door seals
Test the door switch
Test defrost heater
Test defrost timer
Test evaporator fan
Check for a clogged drain tube
Check for refrigerant leak
Freezer is too cold

Check the temperature setting
Test the temperature control
Freezer is noisy

Hissing and popping is normal, it is the defrost heater.
Check that the freezer is level
Check the drain pan
Check the condensor fan
Check the evaporator fan
Inspect the compressor mounts
Freezer runs continuously

Defrost the freezer
Clean the condensor coils
Check the door seals
Freezer starts and stops frequently

Clean the condensor coils
Check the outlet voltage
Test the condensor fan
Test the compressor relay
Test the overload protector
Test the compressor motor
Freezer does not defrost automatically

Test the defrost timer
Test the defrost heater
Test the defrost thermostat
Freezer has an unpleasant odor

Remove spoiled food
Clean freezer interior with a solution of h
Clean freezer interior with a solution of hot water and baking soda
Clean the door seals
Remove breaker strips and check for wet insulation
Water on floor outside of freezer

Check the drain pan
If you have an ice-maker, check the water supply hose going into and coming out of the water inlet valve
Water inside the freezer

Check for a clogged drain tube
If you have an ice-maker, check freezer and ice-maker for level.
With all this it helps to solve the problem....

In my opinion, since your going for the fast freeze mode, your freezer sets to its lowest operating temperature to fast tract the freezing process.

and about the noisy clicking sound it is probably a thermostat or relays depending on your system which starts and stop the compressor.

i think your freezer is just doing fine.

Behind the back panel you will find the freezer fan motor. unplug and take everything out. take the back panel off and find the fan. stick something in the blade like a bannana or whatever (no rags or paper towels though) just something to jam the blade (its plastic so dont break it) replug. remove whatever you put to jam the blade and if you hear the sound then you know for sure it is the fan. got to replace fan if you want the noise to stop
if it is not the fan let me know
hope this helped

Hi, If you say it stops when the door is opened and starts again when you close it, it is the evaporator motor in the freezer its self. The blade/prop is hitting maybe a chunk of ice or may be a part of the casing some where. This motor is 120 volts and the blade is either aluminum or plastic. You can fix this on your own if you are a handy guy, you just need to get back to where the motor is and plug it in to see what it is hitting.The bearings may be going out causing the motor shaft not to be true and hitting. You will be able to see the motor turn and know if it is straight. I don't believe that's the problem, something has moved slightly causing the blade to hit it on start up.I have seen this happen many times.Once you get the cover off, it should be a quick fix for you. Keep me posted. If it turns out to be the bearings as you will see the shaft wabbling, take it out, make sure you unplug it, an get the name Bosch, model, and serial numbers and get one at a appliance parts house. Like I said, I don't think its the bearings or it would stop working or be real noise all the time. The blade is just hitting something small. Keep me posted,
Sincerely,
