I have Blodgett steam cooker model 6s-sb. The problem is both fan motor does not come on when power up. Thanks
Without spending too much time on your problem, I did BRIEFLY perused the schematics in the manual. I think that K7 relay is where I'd start.
Of course, you gave so little information about the functional status of the unit that I might be way off in left field. So, to help you out - here's the manual:
E-SB Series ELECTRIC BOILER BASE STEAMER INSTALLATION - OPERATION - MAINTENANCE
With the schematics in the manual, perhaps you can figure it out by using your multimeter.
I honestly thought that Southbend would've made this steamer for Blodgett. After all, they're both part of the Middleby Corporation.
That's not the case, though. Groen made that steamer for Blodgett:
GROEN MODEL HY-6CAV DOMESTIC HYPLUS™ ATMOSPHERIC STEAMER CAVITIES
This manual is nearly identical to the Blodgett one.
The only thing I see common to both the upper and lower units is the power switch, 24 volt transformer, Circuit breaker for transformer, and main fuses. Other than that everything is duplicated between the upper and lower. All this assuming they know that the timer has to be on and the door switch closed. He hasn't said if the drain is closing and the boiler is coming up to temp. The answer to that would rule out a lot.
Yup. That's why I'd start at K7. Right after T3, K7's contacts must close to get 24v to both sets of compartment controls. From there, each set of compartment controls operates independently. Their respective fans are operated from either K1 (for TOP) or K2 (for BOTTOM).
He didn't say whether he is or isn't getting anything else...other than "The problem is both fan motor does not come on when power up (sic)".
From looking at the schematic (and a picture of the compartment control panels), there's really nothing there (such as lights) to indicate there's power up there. So, the only other way to determine if power is getting to the compartment controls is if there's steam getting into the cooking compartment(s). That would demonstrate that the steam valves are working, so then the problem is indeed isolated to just the motors.
At THAT juncture, we'd then know that the compartment controls ARE getting power...and K7 obviously couldn't be the problem, so look elsewhere for it.
Unfortunately, the question Wendell proposed is akin to saying, "I have power, but my car won't start. What's causing that?"
I think Wendell just wants someone to tell him what part he should order.
Well...that's "simply" impossible. I can't troubleshoot his steamer from my living-room.
Here's the compartment controls schematic so that it's not sideways:
Yes, I agree. But untill K3 is powered by the 11 and 12 terminals on the timer, Without it there is no T3 low voltage anywhere except the fuses and power switch. That energizes the whole upper control. K3 and K1 are energized by the reset as well as the timer, but has to have the water control happy as well as the limits. I would love to have him tell us what he see's with the lights. It could save us all a lot of guessing.
OH. I see the lights in the diagram now. So there are lights.
Maybe he saw lights?
Yes, it'd sure be enlightening to know whether he saw lights...
Me too. I think they just like to tease us to come up with some fictitious answer.
I'm getting tired of waiting...
When Wendell shows back up, stop me.
Retrieving data ...
