Why is my Skov BF 55 Fan motor not running?
- N
  Nicole BrownAug 7, 2025
  Several factors can cause the Skov Fan motor to stop running. It could be due to the fuse switching off, so you should check the fuse size and replace the motor protection with the correct size. Also, a blocked fan motor or too high negative pressure in the livestock house may be the cause; remove any blockages and check the air inlets. Alternatively, the issue might stem from the climate controller signal, start/stop signal, power supply, or a defective LPC motor controller. Check these elements accordingly.

  Abnormal noise from the Skov Fan can stem from several causes. Check the mounting according to the provided document and retighten if necessary. Bearing noise may require you to replace the motor. Also, inspect the fan blades for defects, correct assembly, or dirt; replace or clean them as needed.

What to do if my Skov BF 55 has reduced performance?
- R
  Robert HensleyAug 20, 2025
  Reduced performance in your Skov Fan can arise from a few reasons. The internal temperature of the LPC motor controller might be too high. If the negative pressure in the livestock house is too high, check the air inlets. Replacing the LPC motor controller may resolve an error in the internal circuit of the LPC. High ripple voltage can also be a factor, so measure the supply phases.

Why Skov BF 55 stopped after several restart attempts?
- P
  Phillip EspinozaAug 26, 2025
  If the Skov Fan stops after 5 restart attempts due to the same error within 60 minutes, several issues could be the cause. Measure the supply voltage if it is too high or low. Check for motor errors if the current consumption of the motor is too high. Measure the voltage between the phases if there are phase errors. Remove any blockages if the impeller is blocked. Invert the rotation direction if it's wrong. Measure the voltage going to the motor if there is a phase error on the motor supply. Replace the LPC motor controller if there is an internal communication error.

What to do if Skov BF 55 Fan motor is not running?
- B
  Blake BarnettAug 31, 2025
  If the Skov Fan motor isn't running, check the signal from the controller if the signal from the climate controller indicates a stop (10V at terminal 5). Verify the signal from the winch motor if the start/stop signal indicates a stop (24 V at terminal 8). Ensure there's power from the power supply. If none of these resolve the issue, the LPC motor controller may be defective, requiring replacement.
