Remove the blower and reach up into the duct through the back flow damper and put weather stripping on the 2 edges that are chattering, it will greatly reduce the noise

What would cause the freeze to be cooling normally and the refrigerator side to be at a temperature of 55 degrees?


all it does is the freezer gets cold,the evap fan blows cold air from the freezer into the fridge section so if the freezer is fine,check the air ducts in the fridge section,if a package or something is blocking the vent on the bottom it will get warm or also on your model you have a damper on the top where the air blow into the fridge section from the freezer,you have an electronic damper,there's a door that opens and closes to let the air in,when it's cold enough the door closes when it gets warm the door opens so either the damper is bad or the computer board that operates it is bad,also check the packages in the freezer,if you see frozen water droplets on the packages or ice on the shelves the door could have been left open and the air ducts freeze so no air can pass through,you can hit the air ducts with a hair dryer to melt them out but be careful,don't keep the heat on one spot for to long,you can damage the ducts,also when you open the freezer door you should hear the fan blowing,if not you could have a bad evap fan motor and the air isn't blowing over to the fridge section,the damper is like 45 dollars and the computer board is around 120 dollars,you can go onto the sears site,put your model number in and look at the controls and you can look up the parts.http://www.searspartsdirect.com/partsdirect/part-model/Maytag-Parts/Refrigerator-Parts/Model-MCD2257HEB/3048/0165000/M0703130/00006?blt=06&prst=&shdMod= copy and paste.open the freezer door,listen for the fan no fan bad motor,if the fan is blowing either the air ducts are frozen or you have a problem with the damper or board that operates the damper,you might want to call in a tech for this if it is the damper,it's a little tricky to do this job but that's up to you.good luck and i hope this helps you out.

Tip

My refrigerator is running but not cold enough....


My fridge is running but not cold enough: Start out with the easy stuff first...make sure the lights go out when you close the door(s), make sure the doors are closing properly and the gaskets are closing fully and not torn. Check to make sure the evaporator fan in the freezer is working, this fan blows the cold air around. If the fan is not working, possible bad fan motor - check for power to the fan motor and also check the fan switches around the door openings, ( if your fridge has these switches, not all do ). A common problem cropping up in the last several years has been the air damper not opening up and allowing the cold air from the freezer to be blown into the fresh food section ( mostly on SxS refrigerators ). For many years the air damper was manually operated and now we have motorized controlled or temperature controlled or thermister and electronic boards controlling air dampers, and if this device sticks closed the FF section will normally warm up. An example picture of "one" style and an air damper ( called a diffuser by Whirlpool ). Next would be to check the condenser tubing, a good place to start is to make sure the condenser coils are not built up with dust!! Make sure the condenser fan motor is also working properly. Check for any "clicking on and off" noises from the compressor, is the compressor running.

The most common fridge "not cooling" problem is a frost free failure. Remove the access panel in the freezer section to expose the evaporator coils. If the coils in the freezer section get plugged up with frost, this frost will block the evaporator fan motor from blowing the cold air around. The fan blade can also hit this frost and either become noisy or stop altogether. Locating the defrost timer can be tricky....they are often hidden behind the back bottom corners of the fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some behind the cold control cover. Once you locate the defrost timer, slowly turn the screw like wheel in the middle of the defrost timer with a straight screwdriver until the fridge shuts off. You are now in defrost. If the defrost heater(s) comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not come on, you can ohm test the defrost heater for continuity or volt test for 120 volts to the heater(s). If you have no power to the defrost heater(s) you can also bypass the defrost thermostat to see if the defrost heater will come on, join the 2 wires together to bypass the defrost thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat. If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater* and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.

My Viking Freezer is three years old. The problem is the constant roaring sound it makes. No one can sit in my kitchen, family room or living room for very long before the noise from this freezer gets on...


There are several fans on your unit one on the top with the compressors, one inside the freezer, and one at the bottom. If you open the freezer and the noise gets louder or stops then you know it is the evaperater fan. Sometimes the bearings start to go and they make louder noise. Also check on the back wall for frost you could have a frosting problem and the fan blade is hitting on the ice

In winter, cold air blows back down and out through the fan.


Hi,
Either a backdraft damper was never installed in the ductwork or the damper is stuck open...
Has it always been this way?? If so then the damper probably was never installed and you will need to have one installed to stop the air...
If it was good at the beginning and now is not then the damper is stuck open...you will need to find it and then get it working agian...
The dampers often are right at the outlet of the hood...if you take down the hood it should be right there...

Viking 27" Electric Oven Noise


Hello. The Viking does have fans which operate continuously to insure even baking. If it sounds like fans running, this is the convection fan operating. J.

My 3 year old Viking refrigerator starting making really loud noises today...what can I do avoid a repair bill???


If the loud noises sound like a fan blade hitting ice you have a defrosting problem.

You can try unpluging the unit removing the contents then doing a manual defrost with a fan blowing into the unit for a bit over 2 hours then restarting the unit to see if the noise has ceased.

If it is a noise associated with the compressor you can try pushing it gently in it's floating mounts to try and reposition the unit so the vibration absorbers are functioning properly again.

Lastly if it is the condensor fan making noises break out the crevice tool and remove the lint from the coils. If you have pets this is very important.

Sadly if the problem repeats in less than a week after doing the above the dreaded serviceman / repair visit will be required to islolate the cause or source.

2005 Chrysler Sebring Sedan Fan continues to run


Hi !
A little bit confusing.... though interesting...
when the fan noise is coming please open the hood and physically see if the fan is working.....
What I see is that the thermostat connected to the fan needs to be replaced.
BUT first see physically if the fan IS making the said noise.
Regards

Range vent damper noise


Check to make sure that the installer completely untaped the damper when he installed it. It needs to be able to move freely.

Brand new Viking 3048SS hood - fan switch not working


think i would call viking back and ask for refund of inspection fee and go by the bad switch scenerio the electrician said new fan that would be considered flaws in workmanship in most states dont know where you are located but pretty much same anywhere most inspectors for these companies always try to blame problems off on installers hold your ground and make them fix it and refund that" inspection " fee I've been doing electrical work for several (20+) years it takes longer than 5 minutes to troubleshoot something like that good luck
