Adaptive Defrost Control Bad?

I may have a bad ADC on my Maytag side-by-side (MSD2656DEQ). I found this online Maytag service manual for models similar to mine (didn't find an exact match though) and went about testing the ADC as specified.

http://www.servicematters.com/maytag_library/docs/16010154.pdf

When I jumped terminals L1 and Test, I heard a click that I thought might be the defrost thermostat, but the heating element never heated up. I tried to initiate a manual defrost by turning the freezer temperature control on and off two times in six seconds (as described elsewhere) and still nothing happened with the defrost assembly.
I tested the heating element for continuity and it meaured no resistance, so can I assume the heating element is ok?
I don't want to just assume that the ADC is bad and I'm not an expert on the subject, but from what I've seen thus far, it appears the ADC is bad. But maybe the heating element and/or t-stat are bad. I'm just not sure.
Can someone lend their expertise to my problem?

    I guess what I meant to say is that in testing the element for continuity, it tested ok. There is continuity through the heating element. I guess what I was asking, is can I assume that no resistance through the element automatically means it is ok? Should there be any resistance through the heating element? Thanks.

If there is no continuity on the heating element, it is BAD. Replace the heater and the defrost thermostat at the same time.

Maytag refrigerator.not producing ice .not freezing .not cold enough refrigeratot even though put up temperature to 6@7


When I run into a refrigerator acting like this I start by thinking controls. Controls like defrost, temperature, compressor start components and once I see what it may be I have a look at the likely problem location. Your model appears to have an ADC adaptive Defrost Control=> 67004704 Adaptive Defrost Control
sea_breeze_122.jpg

Here is a photo location of the part=> MSD2652KEB Control Panel
Look inside the fresh food compartment and behind the controls part 12 is your ADC. Once you change that things should begin to get colder providing other parts of the defrost system are OK. Have you noticed ice buildup in back of freezer as a layer of frost building on the rear wall? When you say not cold enough that points to a restriction of air flow caused by no defrost. If I missed anything please let me know. I do think once the ADC is changed you will see it cooling again normally or manual defrost with a hair dryer will keep you for a couple days. Thanks, Sea Breeze

Defrost Heater Resistance Range


21.3 ohms is just fine for a defrost heater. this heater is low wattage since it is an adaptive defrost. you could have problem with temperature sensor since you have replaced the board already.

The automatic defrost cycle is not working in freezer. Can this just be low on freon and making it freeze up? I can defrost and refrigerator will work fine till it freezes up again.


Most times on your model it is the ADC or adaptive defrost control. Part number 13 in photo here=> MSD2756GEW Maytag Refrigerator Control Panel This is behind your controls inside your fresh food compartment.

When the fresh food compartment begins to get too cold is usually when the part #8 in that photo goes bad and that is called the auto air damper

More on that part next time. I believe you will be fine once the ADC is changed, Thanks, Sea Breeze

How do i put this model into defrost? mzd2766gew


The older Adaptive Defrost Control (ADC) boards - short L1 and TEST pins together (you can use the tip of an insulated screwdriver or short length of wire - stripped only at the ends). Newer ADC boards don't have a TEST pin. You can also force defrost by cycling the Cold Control 3 times within 6 seconds and leave it on COLD (this may work only for the newer ADC without the TEST pins).

How to test defrost timer


Yours appears to have come with a Adaptive Defrost Control Part number 61005988 Usally when they go bad being electronic strange things happen.Defost stops or a fan and compressor. They are the most likely reason for defrost failure on your model. On the ADC for your model I dont believe you can manually get it to work for you. Just Replace, Thanks, Sea Breeze

MAYTAG MZD2766GE makes a loud buzzing noise coming from the top of the refrigerator side I think it is when the defrost cycle begins


OK I'm going to ask you some questions about your ice maker. No Problems? You said you noticed this sound around defrost time and have you ever had problems with defrost on this refrigerator before? The way it sounds from here is something related. So I will list them in order of most likely. That would be the adaptive defrost control part number Click Here=> 61005988 then the other two less likely are the defrost heater part number Click Here=> 61006199 When the ADC begins to go bad strange things may happen, The compressor and fans are surposed to shut off and then the defrost heater comes on. Afte defrost begins to reach 50 degrees inside back wall of freezer the defrost thermostat opens to keep the defrost heater from remaining on and defrosting the complete freezer. This for me is a guess and go situation because I am not there to see and hear what you do. So to insure we both are well informed I will leave you with a Service Manual Click Here=> MZD2766GE Your manual covers several models and on page 42 shows a defrost timer and that would be less likely to create strange sounds. If need you may contact me here on Fixya or my Forum=> Appliance 911 My contact information is located above the Fixya Ad on my blog here=> Sea Breeze Appliance Parts and Technical Services, www.pcappliancerepair.com

Because you mentioned that last week you had an ice problem I need to ask was anything done to fix or check the defrost system? The number one reason for this is the Adaptive Defrost Control part number 61005988 If this is OK then we need to check the defrost heater and defrost thermostat. The ADC is located inside the fresh food compartment and behind the control panel used to adjust the temperatures in the freezer and refrigerator.

Freezer coils keep freezing up.


I had a similar problem with a Maytage Side-by-SIde Model MDZ2768GEW, (purchased in 2001). Defrost not working...poor cooling in both the freezer and fridge. We opened up the back of the Freezing side and the coils were iced. This Model is auto defrost so obviously something was not working. We called a Sears repair office and they sent a guy that told us we needed to defrost the unit. Well...I wasn't home and my father-in-law didn't question it - he defrosted it! I was busy at the time and didn't pursue it until the problem naturally resurfaced a month or so later. Not wanting to haggle with Sears over their Tech's lazy incompetence (or the $100 I was out), I decided to commence troubleshooting. I'm an ex Navy nuke electrician and electrical engineer so this didn't seem to be beyond my ability. Not having the Owners Manual, I internet searched until I found this site: www.servicematters.com/maytag_library/html/index.html. You can download your model's Service Manual and root around for other tech info their. I found the manual for mine and performed the troubleshooting for the Adaptive Defrost Control. Its fairly easy to do and you don't have to empty the entire fridge. You do have to empty the upper shelf in the fresh food (cooler) side to gain access to the controls. --This may not be in the exact order needed but you remove the light shield by pulling down on the back corners of the cover and sliding it forward (slotted attachment - no screws). Next Remove several screws holding the fascia / radiant shield on. Then remove screws that mount the control housing to top of fridge, etc. I also removed two screws that mount the ADC to the plastic housing to get access to the ADC. Basically, remove enough screws to lower the top assembly down to get to the ADC... --You may need to turn off the fridge now (or do it before you started the previous steps but the light helped me). If you are not using a Wattmeter, I don't think you need to pull the power cord. --The Service Manual next says to attach a Wattmeter to the fridge (and assumedly plug it back in). Most people don't have a Wattmeter...but what I had is a clamp-on ammeter...which you can get as part of "better" multi-meters for well under $100. An ammeter is good enough if you know how to multiply voltage and current to get VA (or approximately) Watts. Any idiot can do this...I think. P(Power) = V x I x pf. What you calculate with VxI is Apparent Power (VA). You convert to "real" power (Watts) by multiplying VA x pf. You generally have to guess at pf, but 0.8 for a motor/compressor is a good approximation and 1.0 for a heater or indandescent light bulb is roughly good. Enough electrical basics... --With Fridge plugged in, and being careful not to touch exposed connections, move the ADC control board so you can gain access to it (2 screws were removed previously to loosen it from the housing at top/back right of fresh food side). The ADC is a small printed ckt board about 3" x 3". --Use a small insulated jumper (or insulated alligator clip) and jumper Pins labeled "L1" and "Test". These are labeled on the PC board and were the two left-most pins, side by side, on my ADC. The Manual doesn't say whether to leave the jumper on or not. I tried both ways and I believe all you need to do is momentarily jumper the two pins (but my ADC wasn't working right, which I will get to later)...so I'm a bit unclear on this part. Also - DO NOT jumper between any other pins, or you may damage the ADC, if it's not toast already. The pins are close together so you need to take some care in doing this. --According to the Service Manual, you should read about 500-600 Watts of total power consumption if the unit is in Defrost mode. I found (referring to the electrical schematic), the main red power wire (ty-wrapped to a green/yellow wire that goes to the main lights). Power is red so it's process of elimination to find the "right" red wire. It's not that hard to figure out. I also confirmed this by playing with the door switch light and watching amps go up and down as I pressed & released the door switch. Ultimately, I measured about 2.2 Amps with the unit working normally (cooling) and 6 Amps in Defrost mode...and about 120 Vac supply. So...VoltsxAmps=VA, which equates to 720VA. I don't know what the power factor of the unit is...but with the compressor and freezer fan off, and only the defrost heater and lights on...the power factor would be close to 1.0. So my reading might have been a touch high but...what it did prove is that a) the heater works (I could feel heat off of it and I had the freezer panel removed and saw it melting ice), and b) the thermostat was working. --I also confirmed proper thermostat operation by measuring it "open" with an ohmmeter after the defrost cycle and measuring it "closed" once it cooled down enough (book says ~ 45F thermostat opens and ~15F it closes (to allow defrost when commanded by ADC). --What I found was that when I jumpered L1 and TEST, the Defrost didn't come on...until I manually turned the Freezer control off - and then back on again. Once I did this it started Defrosting (amps rose from about 2 to 6, compressor and freezer fan shut off and heater started heating. I repeated this twice after waiting for the unit to cool down after the defrost cycle. You can also just unplug the fridge to terminate the Defrost cycle and if the temp hasn't risen above the thermostat setpoint, you can immediately repeat jumper testing as necessary. --The defrost heater stayed on for about 5-8 minutes and after a total of 23 minutes the compressor/fan restarted - which matched what I read somewhere - though doesn't match the ADC Instruction Manual - which I show a website for further down. --So it appears the ADC is just not entering the Defrost cycle but does exit it properly. I believe that my problem is the ADC as I proved the heater works and the thermostat (as I mentioned earlier). Other than bad/intermittent open wiring, there's nothing else in the circuit and I believe I ruled out a bad connection by taking the thermostat connector apart several times and jostling wires up at the ADC to gain access. According to what I can find, the replacement ADC for my unit is Part No. 12002495. One should verify the P/N for their particular model. You can look at the Instruction Sheet here: www.servicematters.com/maytag_library/docs/16023486.pdf. It also has some info on how the ADC is supposed to work...NOTE: You should verify this P/N with someone, as I will before I order it. FYI...at Partselect.com, they show a replacement PN (their #) as PS2061226, for about $61. I've seen various prices on different sites and this was pretty reasonable. Lord knows what Maytag/Sears would charge. Maybe add a "1" to the front? ;) PartSelect also indicates different "Series" numbers for the same PS number for the ADC...not sure about which one I have so Buyer beware, make sure you resolve this before ordering -- I still have to. Anyway, hope this is helpful to someone out there in cyberspace. I will have to confirm my P/N and then buy the ADC. If anyone out there, esp pros, have any suggestions feel free to chime in. Except if you are the guy that told us to defrost our auto defrost fridge to "fix" the problem, for 100 smackers no less. You Sir, should be caned 100 times for being a slug. No economic stimulus for You!

Freezer not properly defrosting


On the adaptive defrost control board...cut the orange/white wire.
This will put the board into a standard 8 hour defrost cycle.

you cannot do this
just check the defrost heater and the bi metal, if they check good then the adaptive defrost control is bad
