Error codeU60 / L60
ApplianceWall Oven
Quick answer
U60 and L60 mean the cooling fan tachometer is outside 50-750 pulses per second at low speed on Dacor wall ovens.
Model compatibility: Dacor reuses codes across series and model years, so U60 / L60 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Cooling fan failure at low speed: the tachometer reads outside 50-750 pulses per second.
On a Dacor wall oven, U60 (upper or single oven) or L60 (lower oven) reports a cooling fan failure at low speed. The cooling fan tachometer, a Hall effect sensor, registers more than 750 or fewer than 50 pulses per second. It is listed in the manual for 27-inch and 30-inch single and double ovens with touch-glass control, series not named.
What the manual lists
Blocked airflow: if the fan is operating, clear any blockages in the airflow paths
Damaged or detached blades
A bad Hall effect sensor, where the fan runs normally but readings are bad
A bad relay board
Checking fan speed in the service screens, attaching blades, replacing the fan or replacing the relay board are technician work. No functions are available while the code is active, so call for service.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
