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+

After selecting a few ovens based on the mfr's specifications, I plan to send them a thermal "slug" to run in their ovens (a 1/4" thick, high temp fiberglass slab with imbedded thermocouples). Since we are replacing ovens with fixed speed blowers wit
