Good tip, thank you, I will look for a capacitor next time I deal with a blower not working

Hello, yes you are absolutely correct. I agree with your point. Last week,I personally checked out my board on Heller 1088 which is a 8 zone reflow oven (4 on top and 4 on bottom) and the soldering came pretty nice. So comparing with that situation

Thank you guys for the answers. I have solved a part of the problem. I replaced the caps that Rob mentioned and some blowers start working. I still have problems with 2 heats. One of them the blower is not working even changing the cap. The other one

Most probably some of your convection blowers don't work.

Try lowering your blower speeds on the bottom zones. Works as well and lowering temps but easier to control than balancing your delta T from zone to zone.

I used to have the same issue with reed switches on one product we ran. Same oven too. We ended up rigging up an "umbrella" with two titanium stiffeners and bare PCB as the roof. It was hokey but it worked.

Good idea DWL, "Umbrella" thing works to solve this problem temporarily. But do you think it will cause any damage to hitter or heat zone?

Depending on Zone Temperatures, Belt Speed, and Board Density... Some Convection Ovens will drop Zone Temperatures faster than others. They recover by increasing Air Circulation. This can make parts fall off the Bottom-Side that otherwise would
