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 just want to check with you guys, those who have Heller reflow oven and has lifetime warranty if warranty is still lifetime. We were told that warranty for blowers and elements are now just limited to 8 years, though when the machines were bought,

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

We had this happen in a Heller 1808 oven when we placed Tant-A caps in glue (bottom side / no paste). We had our oven retrofitted to control the zone blower speeds. No more problem.

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.

Btw, our's was bought in 2001. So basically they said that it is not covered anymore. But we were never told that they changed the condition, until we were claiming for the blower. But in page 143 of the manual, it states, "...terms of this warranty

Bother are valid choices, Rehm is better made(stainless steel tunnel, lower power usage, threepahes blowers etc) If can afford it would be better choice. From experience Hellers Specs are a bit flaky... But they both will solder PCBs.
