Nu-Vu oven proofer M# sub 123, unevenly cooks bread. door seal is tight. Vent on top of oven sucks air in, it should blow air out

Posted by on

    This is a 3 phase oven but the fan only runs on 120v. I tried reversing the rotation and it helped the problem of the vent tube sucking air in, but made the cooking bread unevenly problem worse. Is there something that directs the air flow thats missing or maybe panels installed incorrectly?

This is probably a three phase machine and the 'phase rotation' is backwards, causing the blower to run backward. Reverse any two of the three phase lines in (power input lines to unit) and it will reverse the motor.

    Is this convection heating (a blower inside the oven) moving the air? Is the fan running? Have you tried an 'oven thermostat' to verify the oven temp compared to the thermostat setting?

I would like instructions on how to set different stitch lengths on my Juki 1541-S.


Puckering is typically NOT a tension problem. But rather a bad needle or not the right needle for the project and thread. Sometimes it's uneven feed but since your 1541 is a walking foot you might have to get the feed timed. I know little about that.

I would first look at the recommended needle thread combo for the fabric. Then the presser foot tension.

Good luck.

The top stitching is good but the bottom is to tight and have uneven stitching


try loosening the top thread tension one number at a time until the stitch becomes regular
also try changing the needle--flat side goes to the back of the machine
if this doesn't help then you should consider having the machine serviced

My Imagine Serger's threading ports are blowing out air when I press the lever, not sucking the thread back in.


Hello Wardmel
Make sure that the serger is set up for threading, now check that the air tubes are not plugged. You should have a long spun wire to clear the air paths.
Happy Stitching
