Rational SCCWE62G dead
-
Original. The replacement one was not the PCB that I needed.
The SCCWE62G has three PCBs, two of which are in the front panel and the other in the cabinet which is “main” PCB (has the SD card).
Of course I bought one for the front panel because that is the only one on PartsTown that said “PCB” for this exact model, but I found that I needed:
https://www.partstown.com/rational/ratl42-00-260p
Which is the newest model, the original design has been made obsolete twice. And the original model when you try to find it on PartsTown or anywhere really is not available except on HeritageParts which states its obsolete then tells you again the next version is and finally TA-DA here we are with the newest version.
I really do not like Rational right now.
-
Yes. I totally agree…
Rational changes their part numbers more than ANY manufacturer I’ve ever seen.
I have twenty-eight Rationals to maintain. 1995 models and up to present.
I have thirteen different parts manuals to cover them all…and ALL the parts price lists they have published that I could find on the internet.
Those parts price lists are updated almost annually…and must be used to cross-reference for any parts number changes.
SO. Whenever I look up a Rational part in a parts manual, I immediately (before getting up to walk to our parts shelves) must look that part number up AGAIN…in their price list…to see if the part number had changed.
All this makes maintaining the parts locations on our shelves quite aggravating since I might potentially have two (or MORE) locations for a given part (we stockall our parts by manufacturer, and then alpha-numerically).
ANYWAY…
the board you’re needing looks like this one…which has (as PartsTown indicated) had a part number change. The one I’m linking below is for a SCCWE202 electric unit, so don’t use it as a reference for the part you’re needing to order:
-
Well damn. Now I feel a bit confused.
This is how I came to believe its the part I need.
First I looked at the manual for the part number of the board which states it is 42.00.160 (attached)
That part is not available on PartsTown …. or anywhere. However on Heritage Parts it has the data about said board, stating it has been replaced by 42.00.080P (attached). And also that it is obsolete but no alternative on Heritage Parts.
Looking that part number up on PartsTown says that 42.00.080P has been replaced by 42.00.260P
-
That’s unfortunately the ways of Rational.
They’d probably initially designed specific boards that were suited for each of their various oven configurations (e.g., gas vs electric heat, countertop vs floor models). THEN (it appears) they came out with ONE board to cover them ALL.

Seems like it.
So before jumping the gun… again.
I emailed Rational asking them for which board is required to replace the 42.00.160
-
I just checked their latest parts price list. 42.00.260P is the part you need.
Here’s that list. Look on page 119:
Service Part-Price List April 1st 2019
In THAT publication, you will find that they don’t even list 42.00.160. Rational does THAT kind of BS too. Namely, LOSING part numbers so that they don’t even appear in newer price lists. That’s why I’ve them from every year – so I can look at an earlier one if Rational if Rational inadvertently fail to list an older number. I usually will find an unlisted number in an older parts price list.
So, look at my picture showing a part number change in a 2018 copy.
Appears that board’s part number changed two or THREE times.

Great. Thanks a lot for that.
-
How does one get the parts price list? Is that something you sign up for?
-
Just download one from their website:
-
-
Wow, that’s insane.
How is one supposed to keep track of these things?
-
Thanks etcofix.
-
I’ve sent @olivero an email which he can forward to you.
-
-
Thanks he forwarded it to me.
I really appreciate all of your help on this.
-
So my new PCB arrived, installed and the screen fired up.
Got a Service 17 error so need Rational to answer the phone and send me a data patch, apparently the install didn’t provide all the data so need to run some recovery software.
-
Hallelujah.
-
Congrats! Hopefully, the patch will be the last piece of this puzzle!
-
-
I hope so. If Rational would answer the phone!
-
So, it is finally…..
FIXED!!!!!!
-
Nice!!!!!!
-
Thanks for the update!
This was certainly a learning experience for me as well and I feel more prepared to address such issues if one of our White Efficiency ovens goes bonkers.
-
Gotta love one that is a challenge. I think we all learned a bit from this one.
-
Definitely learning experience.
Thank you ectofix and fixbear.
-
wow I’m a rational tech and after reading this I’m shocked it took that long to troubleshoot that. also you probably got a service 17 because you didn’t install the pcb correctly. you must have the latest software installed on machine before powering unit up with new pcb as well as having the sd card transferred.
-
wow I’m a rational tech and after reading this I’m shocked it took that long to troubleshoot that.
Thanks for your critique. I’ll offer some alibies, though:
Prior to you, NONE who had responded were factory-trained. Me personally? Me neither. I am self-taught on Rational ovens. Prior to you, none who’d responded are presently field technicians. We are all either IN-HOUSE or retired. The original poster (OP) was someone who’d probably never worked on a Rational before. That’s a HUGE encumbrance and has a steep learning curve. The OP was still learning some of the nuances of electrical troubleshooting. with our guidance over the internet from (at least) two of us who have a combined ninety years of experience. For MANY, mastering those nuances do not come overnight. Mentoring by senior techs is often a prerequisite. The TWO of us were attempting to DO that mentoring…were attempting to do so over the internet. NOT an easy venture Beings that there was confusion over which oven VERSION we were talking about ALSO added some confusion. Unlike you or I, not everyone understands how to tell the differences between a SCC oven…and another SCC oven. For the lack of technical info and clarity over the issue, there were emails traded (with manuals amongst us) and pictures posted (which now seem to have disappeared) that you didn’t see. …and I could go on.The key thing here is that we all come here to either seek help from others with a problem, or to help others with their problem. After all, there is no school for this stuff, nor any SINGLE factory training session to cover it all. The LATTER does help, though.
I have personally been troubleshooting electrical systems for over forty years. I taught it for six years. I consider my experience with electricity to be my strongest attribute. I want to help others achieve a similar level of competence as well.
In that time, I have only been in the commercial food equipment repair field for twenty-two years. Do my experiences make me a MASTER of all things in this trade? NOPE. I’m STILL learn something new every day. BUT…I’ll help others when I feel qualified.
I only know what I know from my OWN training, experiences and from the help of others. Such is as it is for ANYONE here.
You know what you do from your own training & experiences…and I am so glad to hear you are factory-trained by Rational.
Please keep contributing here. However, please keep these things in mind before slam-dunking a thread on a topic which required such collaboration from those who frequent here.
AGAIN. WE (including YOU) are always learning in this trade.

WTF is all THAT!
I’m about to give up posting anything here!
-
should leave it to the professionals… especially not knowing what pcb board or how to install the pcb board correctly. then wondering why you got a service 17. probably didn’t even have the most current software uploaded on a rational usb as well.
-
also if you can’t tell the difference from a SCC and SCCWE that’s alarming. Good luck when working on the new Rational ICP

AUHEA!

I just saw this post and translated. Hilarious, and completely agree.
