We found the blowers were usually fine, but the capacitors strapped to the blower motors were failing. They were under $5 each from Digi/Mouser/Allied/RS. Worth keeping a few around. Last place had 12 Hellers including a 1500 doing ROHS with no is

I am having issues whereby a zone on my heller oven goes through a stage whereby it never seems to stabilise, I have checked the blower motor, changed the SSR and my next step will be to check the heater element, does anyone have any idea what type o

Folks, we've recently upgraded to Heller MKIII reflow ovens with Gen 9 cooling units. We're running N2 atmosphere at 1000ppm O2 and Kester256 solder paste. We're seeing a big problem with flux residues building up in the cooling section of the

I had similar issue with our new 1809 Heller Oven recently. It was blowing off some of the lighter parts. I tried kitchen exhaust fan mesh screen (you can pick this up at your local hardware store). Once I knew it was air flow issue, I played with b

I have 4 Heller Ovens. 3 of them I don't have much trouble getting parts for. They are all 1800 Series with Windows operating systems. The 4th is a 1500 with more like a DOS looking interface. Many of the part numbers are obsolete, and difficult to

Please check mechanical side if lead screws turning freely, binding screw could be the issue. Electrically please check if edge width motor is getting the required voltage. New ovens have the overload relay and the circuit protection fuse. Please con
