I have a Maytag MSD2351HEB. It will be 2 years old in August. I read the post about a faulty defrost system, but then I read other posts about having an adaptive defrost control…so now I’m confused. The freezer still seems cold enough, but the fridge is not. There is frost on the back wall of the freezer. What and how do I check this??? Please help…(and speak in layman’s terms, please). I’ve got 8 kids and 6 gallons of milk depending on me…lol :o

I’m not following where the defrost thermostat and defrost heater are located…I know where the adaptive defrost control is. It is in the control panel on the refrigerator side…but where are the other 2?
Remove the back inside of the freezer. You’ll see the iced up coils. The thermostat is clamped to the coils. The heater is under or woven thru the coils.
Part 3 and 7 on diagram 6. http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5171175
I’ve defrosted the coils w/ a hair dryer. I unclamped the thermostat but do not see a way to test it with a continuity tester…? I tested the heater with a continuity tester and got nothing. My husband also tested the capacitator on the compressor with the continuity tester and nothing on it either. Should the capacitator show anything on the continuity tester? And is there anyway to test the thermostat w/o cutting the wires. The wires are harnessed in with a bunch of other wires and go into the back of the freezer where I can’t see them.
I don’t know of a way if the manual doesn’t tell. I would turn the power off and cut the wires. you can twist them back together with a connector.
You shouldn’t be messing with the capacitor. It’s involved with the compressor.
If you didn’t get anything on the heater then it’s bad.
I replaced the defrost heater a little over a month ago and it has been working great since then…that is, until yesterday. I noticed the fridge wasn’t quite as cold as it had been. I checked inside the back of the freezer and yep…frosting over again…I thawed it all w/ a hair dryer…but it is steadily frosting back over…What next?
The defrost system consists of the three parts discussed in earlier in this thread. One could have gone bad again or the adaptive defrost control could be acting up and not working all the time.
I had the same problem with my maytag, had to replace the auto defrost unit , a little printed circut board. All working fine since replacment.
anyone know how to tell me what to do to initiate the adaptive defrost without waiting for the time to elapse?

this is just a great bit of information :rolleyes: . i’m pretty sure the person asking the question realizes there is a way to push it into defrost, how about letting them know HOW to do it.

the way to do it is in the frig area on right upper top is where adaptive defrost is. If take down the control levers. there are two screw (philips) and two nuts driver screws 1/4 in head. to get to them have pull down cover by pulling down forward part and back and slide forward towards you. then remove 2 screw and 2 nut driven screw. there is on back of frig. when all parts down you can get to adaptive defrost. It held in by 2 screws. on circuit board there is pin called test and 1. If you jumper them by screw driver or use wire it will send the defrost timer and heater in the freezer part to defrost. then if it does then it working right.
