Hi

I have a small transformer sitting on my desk. It came from a Frigidaire oven PCB that set temps and controls the operation,
size is 34 x 34 x 32 mm excluding the 5mm length of the pins at the bases. Takes in 120VAC - output is not known.

The unit was damaged during a power surge, damaging the primary winding. There are three (3) pins on the Primary winding and four (4) pins on the Secondary winding.

Markings on it are:
LEI-4 0306
E154515
B-2
Class 130 (B)
LS-A7632-PT
Mod. NO.: 35DOBOP-004

The primary winding is burned up (power-surge) - I can not measure and don't know the Primary Resistance.

I have not measured the secondary resistance, but I would assume I could, if needed,..

Any ideas WHERE I can buy a replacement unit??

Any recommendation is appreciated,... Thanks

hello there. Im having the same problem you had a year ago and was wondering if you had found any information on the pcb transformer 35dobop-004. My cell number is 229 376 5199. Call or post if you can help

It's highly likely there is no replacement, it's presumably a custom made transformer? (as is common on pretty well all commercial gear) and the manufacturers 'repair' option would be to replace the entire board - assuming it's still available.

Assuming you can work out the specs then you could perhaps find a transformer to replace it, but it's more likely you would need two transformers to provide the required voltages.
 
This thread began about 7 years ago. I would guess there is no longer an issue? :facepalm:

Umm...
Will a mod come around to lock it? And create a new thread for post #6:woot:

Not real sure about that part. Very good question. Post #6 would look rather lonely by itself. :)

The transformer you are looking for is 120v input, 16v center tap. The center tap is where a capacitor is connected for the clock pulse timing.
