Re: Dead Oven Control Board, Possibly Transformer?

are the contact details no use to you ? i would be emailing them for details and availability . you never know you might be lucky and get a free one .

Yeah, I suppose I should consider contacting them. I just figured if they were at all interested in providing support for the thing then they would at least have some basic specs on the website.

The connector on the red wires and F1 look black?

Well, i would expect it to look black when its PVC sleeved :P

Thanks, but I'm afraid a link to their website isn't all that helpful... A search for their own part number, on their own website, comes up with "Sorry, nothing found." If I've missed something, then I sincerely apologize; please provide further details if possible.

Here is what I would if I were doing this repair this is only a recommendation

I would recommend first removing the transformer and check the secondary winding side of transformer as mentioned earlier

If you have a bench power supply ( find the diodes that are on the secondary side of the power supply rail you are going to have use the pins that were for the transformer and you inject power into the pins on the board start at one volt and slowly turn the voltage up until your display power on )

You need to very careful do this procedure and watch for any and all devices around the the transformer secondary side pins for anything that is getting warm or hot do not ignore any issues

remove it and check the resistance of the windings

Six long years ago, @tom66 helped me save my plasma TV here on BADCAPS, and it's still going strong. Fingers crossed for another win!

I have a Frigidaire oven, rarely used, that I noticed was dead at some point during the summer, possibly after one of the bad storms. The light still comes on when the door is opened, so the circuit has power, but no sign of life from the LCD or the button panel. The control board part number is 318010700 and does not seem to be available any longer from any supplier, but there are companies that will repair them for $150-$200. Obviously I'd like to do it myself.

I think the problem may be the transformer, but I'm just a random tinkerer, so not much confidence in my conclusion. The primary side looks toasty, but I'm not sure if that's just cosmetic? Anyway, I probed it and got 120V on the primary side, but only 0.1-0.2V on the secondary pins. I'm not accustomed to measuring such low AC voltage, the lowest range on my MM is 200 V, but I'm pretty sure the secondary is supposed to be around 10V because there are some remote 9V relays for the fan and oven light. The label on the transformer shows Robert Shaw PT# 10-84-00 and V&F PT# R14P20, but I'm having trouble finding a replacement or even the specs for it.

Any help would be greatly appreciated!
