Sunbeam 3837 Toaster Schematic
 

Wow, am I behind the times. I figured a toaster was on or off. Wrong.
This one, a fairly recent model, has a circuit board inside. I guess
it accounts for the bread's mood and the room's feng shui to decide
when it should shut off.

It gets a little warm, enough to scare the bread, but not to toast it.
Does anyone know of a schematic for the board? I have to say it's
probably a moot point, as I have an old toaster that runs flawlessly.

Thanks.

You'll never find a schematic for something like that, they're confidential
information. That said, what good would it do? These boards are pretty
simple, just troubleshoot it like anything else, the only thing it's really
good for is the challenge.

This is where you can perform a service to the repair community. Trace
the circuit and then post it on a public Web site or I'll be happy to
include it in the S.E.R FAQ schematics page.

It's not a quad core PC 10 layer mainboard, just a little PCB probably with
under a dozen parts on it. :)

Hi, Sam. It's a thought.

Yeah, pretty much. I have so much stuff here that I hate to think that
I'd take the time to fix a toaster. They must cost $9.95 at Bed, Bath
& Beyond.

Thanks.

(I suppose this means that the Chinese spambot will reply with several
more spam posts.)

Yeah, but it's the challenge! You don't want to let a $9.95 toaster

I'm afraid that's about to happen. I opened up the toaster today. The
number on the PCB is TS3020 220-0448. It has 3 transistors, 8 diodes,
1 zener diode, one negative NTC device, 15 resistors, 4 capacitors,
the potentiometer (light-medium-dark) and a black plastic cube about
3/8" on each side, bearing the part number 943-1C-24DS. Markings on
this last part say "12A 125 VAC, 7A 250VAC, 7A 30VDC." There is a low
voltage circuit in the toaster that provides power to the solenoid
that holds the bread elevating mechanism in the locked position until
the bread is dark enough. Then the power is shut off and the solenoid
lets the latch release. The circuit could easily be traced.

Should the 943-1C-24DS be at fault, there are plenty of places that
have them, but they are of the $250 minimum order-type parts houses. I
couldn't find a description of that part during a brief search.

My American-made toasters that work just fine are looking really good
right now. I'm not sure I need this big a challenge. This Chinese-made
Sunbeam my get left out at the end of the sidewalk for someone else to
ponder.

Thanks again.

That mystery part is a relay, 12A 125V rated contacts and I would guess with
a 24VDC coil, but you can find that out easily enough. Apply voltage, it
should click, you should then measure a dead short between two of the pins.
If it's more than an ohm or two the relay is bad.

I assume that the relay closes to turn on the element? Try bypassing the
contacts and see if the element heats up properly.

Where did you find an american made toaster? I looked for one when the super
cheapie I had fell apart, I finally settled on one that was made in China,
every one in the store was.

Oldies but goodies. I never throw anything away.
