JennAir SVD48600P - Power Relay Board Fail

15 posts in this topic

Hey guys - new member here but experienced appliance repair guy.  Have a JennAir SVD48600P range with the F2 code.  Temp sensor is fine - repair manual says to replace "Power Relay Board".  Parts diagram shows callout 29, p/n 71002144, BOARD, RELAY (LWR) Note: BOARD, RELAY (CONVECT), but most of the usual repair parts sites show that p/n as discontinued.  I sent emails to 2 different board repair places and both refused saying they don't fix that part number.  Any ideas besides get a new range? I am hoping there is a new part number that crosses to that old number.  JennAir Range Parts Manual.pdf

Is that the board with (2) Relays on it

(and two Diodes)

 

the Relays could be replaced, if you can solder

Are you sure that Board is bad  ?

What's the symptoms ?

It isn't the one shown in the pic - which I think might be the Downdraft Board.  The Power Relay Board is two to three times bigger than that - and is shown on page 2-9 of the Repair Manual - which was sent to me in another posting but I can't attach it to this thread due to its 5.7Mb size.  The manual's first page is titled, "Maytag Appliances - Electric Slide In Service Manual" and marked with a "16010191, Issued 9/00" in the lower right corner of the first page.

 

The symptoms are the F2 code in the display and that the heat never turns on.

,

No Bake NOR Broil ?

would seem to be a bad Oven Thermistor

Did you check it's resistance ?

usually about 1000 OHMs at room temperature

Measure resistance at the Relay Board connecter J10

Ive searched and searched. That board is gone. You cant even buy the board it subs over too. You have to find somebody with an appliance graveyard. 

Check the whole wiring harness, swap the temp probe for fun, repair the board, or condemn it. I've had rebuild jobs escalate to the point that corecentric wanted me to send in the touch panel and transformer. At a certain point its just no longer worth it.

Just remember when looking at the service manuals for this unit you have a P model which is the pro series. There is a board on the back, but that is strictly for Down Draft operation only. The board pictured a post or two back is for cooling fan and door lock only. The brains of this outfit is the clock assembly. If the sensor ohms fine, from the clock down, and you are 100% sure it is not the sensor or it's circuit, then the clock is what you need. Remember, sometimes sensors (and loads) ohm fine but are still bad. Prior to ordering a control I always have a sensor I put on the circuit to confirm. Does not happen often, but once was enough for me to always be sure.

Is anyone able to look at the picture on page 2-9 of the Maytag Appliance Repair Manual (described above) and make out the labels on the arrows.  The pdf copy sent to me by the moderator has black covering the labels such that I can't tell which board is the "power relay board".  I believe from the relative size of the two board shown in the parts diagram (nos. 28 and 29) that it is the larger board on the left side of the picture.  That would at least allow us to know what it does look like - and again - I don't think it is any of the boards pictured above or in any of the links.  Thanks.

What about the board at the below link?  It looks right - just not sure how the numbers might cross over to the p/n listed in the parts list I have (71002144):

I got that link at the below page - that was pulled up on page 1 of a Google search - and it looks like it might have been from a previous post on an older version of this appliantology website!  The page has the same samurai graphic at the bottom!

If you click on the link in that article,

Power Relay Board (PRB).

and then scroll down,

It shows (4) Relay Boards for that model

? ? ?

If you enter 71002144 into RepairClicnic parts search box,

it responds:

Sub 12001690 71002144

 

If you then enter 12001690 into the parts search box,

you get the Board I posted above

? ? ?

 

also, 71002144

Well now I am confused - one expert says the Power Relay Board is no longer available or repairable.  The other expert says it is not the board the service manual says to replace (though I will admit that the service manual is pretty generic), it is the Oven Control Unit - in the unit that actually has the display board/switch membrane in it. I suppose, either way, these "boards" are obsolete/out of stock.  I think I need to just bite the bullet and buy a new range - after all, it is 15 years old and has lived a good life!  UGH  Thanks everyone for all of the expertise/help!  You guys ROCK!!!

Are you sure the Sensor is good

(measured OHMs at wherever Board it connects to)

 

good website for options / dimensions /etc..

lots of multiple choice drop-down boxes, etc ..

I actually managed to find that power relay board, and of course the clock is available which is what it probably is as Sensei Trying to help suggested.

On sensor error codes, if the sensor is fine, and you know it, whatever the sensor connects to is the problem unless there is a relay stuck on an aux board causing an element to stay on and it truly is a runaway temp. In this case, on the schematic I pulled, the  pro style like you had showed the sensor to the clock.
