We have a Heller 1707EXL that we purchased in 2006. During the first year we had 2 blower motors go bad. After the second one went bad, Heller sent a technician who replaced every blower motor on the oven at their expense. Since then it has been 5+

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

I am wondering if anyone has had issues with their Heller oven rails warping. It appears that our 1800EXL and 1900W oven rails sag after time. They eventually contact the safety mesh and then create hestitation of the chain, thus creating defects.

I think the problem is going to be the cooling zone location. All of the heat zones are built the same, but the cooling zone can not be moved easily.

Brad, I sell both machines on the used market. If you buy the proper oven for your use you should be very happy with either. Both companies are very reputible and responsive when you have problems.

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.
