I have a Maytag MSD2754GRW that I cannot get below 40 degrees on the fridge side. I have done the following:
Replaced the defrost timer
Replaced the defrost heater assembly (therm included I believe)
I have defrosted the freezer coils as they were iced up a bit.
And the bone headed thing I did without really knowing was I turned an adjusting screw on the cold control that controls the damper I believe. On the outside of the adj screw hole, there are letters INCR with an arrow. I interpret this as "turn this way to INCREASE cold air flow". Is this correct?
any help is much appreciated.
Oh, and the freezer side is working fine btw.
thanks, Kent

What's the Freezer Temperature ?

Is the Evaporator Fan and Condenser Fan running ? (when the Compressor runs)

What's the frost pattern on the Evaporator look like (picture) ?

Probably but it is not meant to be tampered with by novices (and often not by technicians either).

How are you measuring that temperature?

What is important is actual food temperature. The proper way to measure that is to put a container of water on a middle shelf and then measure that water temperature after 12 or so hours.

Is the damper door open or closed at the time it isn't keeping cold enough temperature?

Clear "ice" or white, snow-like "frost"? it is an important distinction in refrigerator repair.

Yes. Frosting should be uniform across its whole surface. An actual picture of what's there might help.

That's another thing that might be helpful to know but the actual food temperature in the freezer.

Also;

Did you check and/or clean the condenser?

Is the condenser fan motor running whenever the compressor is?

Is the evaporator (freezer) fan motor running at least whenever the compressor is?

The freezer temperature is -8



Yes, the evaporative fan and the compressor fan are working.



The frost pattern is not uniform. The last time I defrosted it (last Friday), it had clear ice in many areas and the area between the fins were iced up.



I am using a regular outdoor thermometer. I will try placing a glass of water in the fridge and put the thermometer in it. but I have been using that all along and have used as a bench mark so to speak.



Last time I had the control panel off (last Friday), I check the damper door and it was open.



It seems just to get progressively warmer, not cold one day and warm the next.



I have cleanced the condenser and compressor area, a little dirty, but not too bad.



This is what I did last Friday- I pulled the freezer back panel and observed the coils iced up as before. In the fridge, I removed the panel that holds the controls, timer, etc. I manually sequenced the timer until it clicked one time. I noticed the heater element getting very hot, so I know the timer is talking to the defrost heater. I do not believe the condenser fan stopped during this test. I did not let it finish out the cycle, but after I saw the heater was working, I sequenced the timer until the next click and the heater did not turn on after that. At this point, satisfied the timer was talking to the heater, I powered down and defrosted the freezer and put everything back together and powered her up again. So the last couple of days she has been running at about 38-40 degrees, but afraid she may creep up again soon.

Its almost as if maybe it is defrosting while trying to cool down if that makes any sense?

So suspecting the cold control at this point? Possible? Thats the only other piece of the puzzle, correct?



BTW, this Maytag was included in the recall where a relay that turns the compressor on and off was replaced. I called the repair shop that replaced the relay and they indicated the recall part would have no effect regarding this issue...thoughts?



Also, thank you so much for the help, it is much appreciated!!

Don't lose that Spring when checking the Damper Door

Does the Compressor run "forever" ?

It should be about 1 hour ON, then 1 hour OFF.

The frost pattern should be uniform, a light frosty pattern.
Clear ice is not good (sealed system leak ?)

The Compressor, Condenser Fan, and the Evaporator Fan (all wired together),
should stop during Defrost (function of the Defrost Timer)

Is the Return-Air Flap (bottom left wall in Fridge) working or froze ...

Maytag Fridge Bulletin

I used Clear Duct Tape on my vents MSD2756AEW

Too late on the spring for the damper, the spring shot out when I was checking, but successfully replaced back and working now

No, the compressor does turn off from time to time, will have to check the every other hour part though.

Yes,I understand about the ice. Will monitor.

I have a blue see through plastic cover on the return below, seems fine, not froze up

so far, running still at 40 degrees....will continue to monitor

Does the cold control, timer and defrost heater and thermostat all work in tandem? I cold control is the only component I have not replaced..so wondering...from the pictures, it looks like it has electrical connections so was wondering about working together with the timer, etc.

thanks again for the help, much appreciated.

Speaking of the defrost timer, I purchased and replaced original one with a universal timer ( has extra wire for continuous run versus not), but not real confident about it. The instruction said to place the extra wire on the number 1 terminal of the timer, which I did, but like I said, not real confident it was working. Last time I defrosted, I put the original back in and performed my test by turning the timer until it clicked. then the defrost heater turned on, so I believe the timer istalking to the heater just fine...just monitoring right now

Yes, the Black Wire goes to Terminal #1

The temperature of the Freezer tells the Cold Control to turn on the Compressor (unless the Defrost Timer is in a Defrost Cycle).

About every 8 hours, the Defrost Timer kicks in and disconnects the Compressor (and both Fans) and then connects the Defrost Heater
for up to 25 minutes.

Unplug Fridge and use a hair-dryer to completely defrost the Evaporator Coils to start fresh.

Then check the frost pattern on the Evaporator Coils after about an hour of Compressor run time.

OK, thank you.....it appears the temperature of the fridge is creeping upward again. I will defrost again as you recommend and check the coils after an hour or so. Will take a picture as well. Any ideas you have in the meantime are appreciated.
thanks again.

Here are some pics prior to defrosting. This is only after 5 days
