  Kayla TateAug 16, 2025
  If your Drive DeVilbiss Healthcare Medical Equipment is warm to the touch and cannot be restarted for several minutes, it could be due to several reasons: * The compressor might have overheated because of occluded filters. * There could be a restricted input or output air passage. * The line voltage might be too low or too high. To resolve this: 1. Clean or replace the filters. 2. Remove any obstructions. 3. Check the line voltage and use an alternate circuit independent of other appliances. Also, a defective cooling fan or compressor could be the cause, requiring replacement.

  If your Drive DeVilbiss Healthcare Medical Equipment has a continuous red light and a continuous audible alert and is warm to the touch, the internal temperature is too high. Move the unit to a cooler location. Also, ensure the unit vents are clear, the unit filters are clean, and the cooling fan is operating. Replace the fan if needed. Finally, ensure there is proper voltage to the unit; if the voltage is correct, replace the capacitor or compressor.

What to do if my Drive DeVilbiss Healthcare 1025DS Medical Equipment is pulsing and neither the compressor nor the fan is working?
- A
  abrooksAug 31, 2025
  If your Drive DeVilbiss Healthcare Medical Equipment has a pulsing audible alert and the compressor and fan are not operating, there may be an external or internal power failure. Ensure the voltage is correct and that the following parts are functional: AC outlet, power cord, IEC connector or cord connection, main wire harness, and circuit breaker. Correct as needed. If the issue persists, replace the power switch.

Why is the oxygen flow fluctuating in my Drive DeVilbiss Healthcare 1025DS?
- J
  jodiwoodsNov 18, 2025
  If you're experiencing fluctuating oxygen flow with your Drive DeVilbiss Healthcare Medical Equipment, here's what might be happening: * The humidifier could be occluded, requiring cleaning or replacement. * Filters might be occluded, also needing cleaning or replacement. * The cannula and tubing might be occluded or defective; detach the cannula and check the tubing for kinks or obstructions. Clean, straighten, or replace the tubing if necessary. * Excess oxygen tubing may be in use; this unit is designed for up to 50 feet (15 meters) of approximately 5/32” (4 mm) inside diameter tubing. Smaller tubing or flow restrictions may prevent desired flow. * There might be a leak in the system. Check all hoses and fittings. Additionally, the flow meter, compressor, compressor reed val...
