My Jenn Air wall oven is showing error 4d21. Looking it up tells me low fan rotation error. What parts do I need? And what would be the cost?
The error code indicating the fan rotation error would mean that the fan is either bad or has build up in it that is not allowing it to rotate freely. You will want to pull the fan out and check for obstructions. If clear then replace fan part number 74008383.
How do you replace the tangential fan. The oven, non-convection mode, sounds like a saw.
Answer Hi D.M. Remove Power. Remove door, (if needed) for accessibility. Remove control panel lower trim panel. Remove and unhook the control panel ribbon cable and electricial connectors. The fan assy. part # 74008383, is bolted in the LT. Rear behind the control panel. Reassemble on reverse. Thank You.
