  If the blower does not start when powered up: * First, remove the cover. * Then, check for disconnected wire harnesses and reconnect them if necessary. * Next, check the fuses. Without AC power, measure the resistance across the F1 fuse with an ohmmeter. If the resistance is not between 0.0 to 0.5 ohms, the fuse is open, and the power supply board should be replaced. * If all fuses are closed, install a blower that is known to work properly and power up the unit. If the new blower works, replace the old blower. If the new blower still doesn't work, replace the control board. * Finally, replace the cover.

  If your DeVilbiss Medical Equipment blower is making excessive noise, consider the following steps: 1. Remove the cover and control board. 2. Check the assembly of the foam, blower, and silicone isolator for correct placement. 3. Inspect the blower for any visible space between the blower halves; if you see a space, press the halves back together. 4. If the assembly is incorrect, reassemble the components properly. 5. If the assembly is correct, the blower should be replaced. 6. Replace the control board and cover.
