How often do you have to replace the blower motors? I will ask the oven manufacturers what the average MTBF is for their blowers. We have numerous BTU's and I don't think any of them have required replacement before 8 years (single shift). Once they

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
