Was wondering if anyone knows if the thermostat included in the 12002754 kit as a fan control thermostat (67005902) has the same specs as the defrost thermostat WP67003426 (Spec: L42-30f) ? (This is for a ABR2527FES refrig)

The background is, I had warm refrig and ice on exchanger so wanted to replace the defrost thermostat, thermistor , and control board to be safe. The description of the kit on most part sites says it includes a "Defrost Thermostat". And mine arrived with no directions, so I installed all the components and the stat as a defrost thermostat. Then, later thinking about it, I thought it was odd they included spade connectors when it needed to be wired in directly. I then found the instruction sheet here https://www.applianceblog.com/mainforums/attachments/maytag-bm-frost-kit-repair-pdf.3057) - and in those directions - they say to use the thermostat as an additional thermostat to control the fan instead. Also, it lists the thermostat as a diffferent part number, 67005902, which no parts distributor seems to have a spec on and of course Whirlpool has no idea and I can't get into service/tech suppoort. So now I don't know if I have potentially installed a thermostat with a different open/close temp or not. I'd assume the spec would be the same to control the fan at the same temps as for the defrost heater thermostat , but wanted to verify, because of the different part numbers.

Also, not understanding why the instructions say to put into timed instead of adaptive defrost. My only thought was this kit was originally for some very specific frost issues and not for other component failures, since it also mentioned using RTV to seal corners of the cabinet. Never had any issue like that, just that defrost stopped working.

Thanks,

Mike

Hi Mike, that's a good question, but I don't know the answer, but the defrost thermostat specs are the same. Hopefully another tech can answer that in detail for you.

Rick explains it in detail here:

Difference between defrost Adaptive y Defrost Interval?.

I just installed a new control board (Part Numer: 12002754) in a refrigerator Amana. The main problem or reason for the repair was that the evaporator is filled with ice or frost, preventing the passage of air into the fresh food. Defrost thermostat was changed and the same problem, so he...

Here's your parts diagram: Parts for Amana ABR2527FES

At the very bottom of that page it says the one your model takes is this one, which is the same specs as in that kit:

Thanks for the additional info, Jake! But where do you see the specs on the thermostat in the kit? I know the one they show as required is WP67003426, but the instructions for the kit show the one included in the kit is 67005902, which doesn't seem to have a spec anywhere (Unless you mean you found this spec somewhere else and 67005902 is an L42-30F ?
I think I am leaving this control board in adaptive mode, as that's how I believe it was set previously, and I had no issues with internal ice buildup till recently which I assume was either a bad thermostat or control board. If I still have issues going forward, I'll try fixed mode and also maybe try adding the second thermostat connected to the evap fan as the instructions show.

Thanks,

Mike

Ok Mike, sounds good.

But where do you see the specs on the thermostat in the kit?

I saw it yesterday, but can't locate that page I was on now, sorry.

The specs should be stamped on that defrost thermostat in that kit.
