About a month ago I thought to myself, man, the fridge got quiet(er) all of a sudden. Didn't think much of it - until last weekend when I noticed the freezer was cold - 0 F but the fridge is warm - 48 F. I took off the freezer panel and noticed the heat exchanger was frozen on the right side (picture attached). The evaporator fan was spinning away and the auto damper was pivoting fine and would open and close based on how I set the temp lever for the beer cooler side. Then I figured out why the fridge got quiet - the condenser fan does not run. So here is what I am doing now - defrosting the unit to see if I can get it working again - and then I will start to work backwards - I guess i should start with the adaptive defrost? I dont have the tools to test the ohms as mentioned in other threads - so any advice on how I should proceed would be appreciated. the attached pic was taken about 10 minutes after I initiated the manual defrost. The left side of the coils had just a thin film of frost (which I gather is normal) Also - there was no frost on the inside of the freezer and the evap pan was full of water - it is not evaporating. thanks! jim note to self: evap coils are SHARP!!!

After it finishes defrosting, let the Compressor run an hour or two, then post another picture. Also note whether both Fans were running ...

ok - fired it back up. Evap fan running, condenser fan still dead. Also, I have maytag coming out today to do the recall repair. Does that relay effect the conderser fan? Also after about 5 minutes the condenser is really really hot to the touch thanks jim Last edited on Fri Oct 30th, 2009 01:54 pm by jimmyt |

Sounds like a bad Condenser Fan. Both Fans and the Compressor are wired together... they all get the same power. click on picture  Last edited on Fri Oct 30th, 2009 02:12 pm by RegUS_PatOff ____________________ RegUS_PatOff http://www.youtube.com/watch?v=oPAY2LsKVEw my video production: “Easter Seals Walk With Me” (also in HQ) http://www.youtube.com/watch?v=-EBiLyYXMiA Upon leaving this Earth "Do you want the Smoking or Non-Smoking section ?" |

7 hours later and here is what I have... Freezer at 0 F and beer cooler at 35 F The repair tech came out to replace the relay and he was kind enough to test the bi-metal and heater - both checked out ok. He suggested that perhaps the bad condenser fan was causing the trouble and that I should wait about a week to see what happens - Samuri - do you concur? I did replace the condenser fan. Which way should it flow air? I hooked it up the exact way as the old one and it was pulling air thru the condenser and blowing onto the compressor. Makes sense to me as it is pulling the cooler air. Attached are some images of the evap coil after 7 hours .. any advice or suggestions would be appreciated. thanks jim Attachment: Picture 005r.jpg (Downloaded 35 times)

What "Relay" and why ? ohh .. the Start Relay (recall) on the Compressor ? the Evaporator Coil should be lightly, evenly frosted after an hour or two of Compressor running, (unless it just went through a Defrost Cycle)

depends on how much food .. may take 24 hrs ... (the Compresssor only runs when the Freezer temperature isn't satified)

Which way should it flow air? I hooked it up the exact way as the old one and it was pulling air thru the condenser and blowing onto the compressor. If the condenser fan wasn't running when the compressor was running, then bad condenser fan, slam dunk. If you used an OEM part, it only plugs in one-way so air flow directions will be correct. BTW, running the compressor for any length of time without the condenser fan running will damage it by overheating the windings, eventually creating a high impedance path to ground == new compressor. Looks like you caught this one in time!

thanks for the advice.. it cooled down to 36 overnight.. although I think I am still not getting enough airflow, the problem could be with the air flow damper - it moves like it should, it just does not open very wide. I used to see / feel a lot more air coming out into the fridge portion.. I may manually adjust the damper to see if that provides more airflow... of course you fix one thing, another breaks - I sprung a leak in one of the water tubes leading to the icemaker... looks like another trip for some compression fittings and poly tubing!

Temperature tells the story. If the temps are good in both compartments then don't go lookin' fer trouble.

Don't mess with the Damper ... Just do the "tape or replace ($12) Louvers" as mentioned on page 6 of this Maytag Service Bulletin

When it rains it pours. The airflow is terrible to the fridge and the temp wont get below 40 F. The airflow is definatley reduced to the fridge. I have taped the louvers per the service bullitin. I wonder if I should replace the tempurate control via the kit as shown in the bullitin. I am going to experiment more tonight - check for frost and then leave the damper open and see what the temp does. Also - a new problem has popped up - the water line coming out of the water valve at the bottom of the fridge was brittle and sprung a leak. After fixing it by adding and inline compression fitting - every time I get water out of the fountain, it also sends water down the ice maker tube. As a result, the ice maker is not working and neither is the fountain. Is that a circuit board issue? thanks jim

How's the Evaporator Fan and is the Air-Return Duct frozen shut ? MSD2756GEW Sevice Manual

will let you know tonight. However, when I checked it over the weekend, the flap on the return duct moved freely and was not blocked. As far as the evap fan, it was running with no problems and seemed to be blowing a good amount of air.. in fact, I felt a lot of air blowing out the rear freezer vents were I put the tape.
