  If the DeWalt Air Compressor motor doesn't run, several factors could be at play. First, the motor overload protection switch might have tripped; if this occurs frequently, professional service is needed. A blown fuse or tripped circuit breaker could also be the cause; replace the fuse or reset the breaker, ensuring you use the correct type and rating. Low voltage conditions or an improper extension cord can also prevent the motor from running. If none of these resolves the issue, there may be a defective motor, requiring assistance from a service center.

Why is my DeWalt D55167 Air Compressor not supplying enough air?
- A
  Amanda ClarkAug 4, 2025
  If your DeWalt Air Compressor isn't providing sufficient air, consider these possibilities. Excessive air usage over a prolonged time can reduce the available air. Make sure that the compressor is large enough for the accessory. Air leaks can also diminish the air supply, so tighten all fittings. Also, the regulator might not be correctly adjusted for the accessory you're using; adjust it under flow conditions while the accessory is in use.

What to do if the safety valve pops off on my DeWalt D55167?

  If the safety valve on your DeWalt Air Compressor is popping off due to excessive air tank pressure, it could be due to a pressure switch malfunction. The pressure switch may not be shutting off the motor when the compressor reaches its cut-out pressure, or the pressure switch cut-out is set too high. In this case, set the Auto/Off switch to OFF. If the unit does not shut off, seek assistance from a DeWALT factory service center or an authorized service center.
