Why does my Invacare Perfecto 2 SeriesIRC5PO2AW overheat?
- K
  Karen WilsonAug 22, 2025
  If your Invacare Medical Equipment unit overheats, ensure it's placed at least 30.5 cm (12 inches) away from any wall and not on thick carpeting to avoid blocking the base exhaust vent. Clean or replace the cabinet filters if they're dirty. Check the fan to ensure the leads are connected, the fan isn't defective, and it's installed correctly with the airflow arrow pointing down. Clean the heat exchanger if it's dirty or plugged. A defective compressor, capacitor, or motor windings can also cause overheating, so consider replacing the compressor or capacitor. Finally, have the line voltage inspected by an electrician, as excessive voltage might require a voltage regulator.

What to do if Invacare Medical Equipment shows low concentration?
- G
  Gina JohnsonAug 25, 2025
  If your Invacare Medical Equipment shows low concentration, with the red indicator on, yellow off, and green off (SensO2 units), and a continuous audible alarm sounds with system shutdown, several issues could be the cause. Start by cleaning or replacing the cabinet and compressor inlet filters. Inspect the compressor for defects, capacitor issues, motor winding problems, worn seals, bad bearings, leaks, or insufficient voltage. Also, check the heat exchanger for leaks, replace the exhaust muffler if it's dirty, ensure the fan is operating correctly, and inspect the sieve beds. Finally, check for any kinks or blockages in the tubing and consider replacing the P.C. board if it shifts at the wrong pressures.

Why is my Invacare Medical Equipment so loud?
- S
  Samuel RogersAug 26, 2025
  If your Invacare Medical Equipment is excessively loud, check the pneumatic exhaust system. Replace the muffler if it's cracked, damaged, or missing, and reconnect or replace any disconnected or damaged muffler tubing. Ensure the compressor inlet filter is present and not missing, and replace it if necessary. If the compressor has been removed, replace it. Also, ensure you're using the correct factory OEM sound-reduced inlet HEPA filter.

What causes low pressure in Invacare Perfecto 2 SeriesIRC5PO2AW?
- M
  meghanhamiltonAug 28, 2025
  If your Invacare Medical Equipment is showing a low pressure issue, indicated by the red and green internal status indicators flashing, the control panel indicators showing red on, yellow off, and green off, a continuous audible alarm, and the compressor shutting down, there are several potential causes. Begin by replacing the compressor inlet filter if it's dirty or plugged. Inspect the compressor for leaks at fittings or tubing, a leaking relief valve, or worn cup seals or gaskets and repair or replace parts as needed. Check the heat exchanger for leaks and replace or retighten components. If the regulator is cracked or leaking, replace it. Finally, inspect the P.E. valve for leaks and replace it if necessary.

Why does my Invacare Perfecto 2 SeriesIRC5PO2AW have fluctuating flow?
- M
  Matthew BarrettAug 30, 2025
  If your Invacare Medical Equipment experiences fluctuating flow, check the regulator and flowmeter. Ensure the regulator is set correctly and adjust it as needed. If the flow remains unstable, inspect for leaks starting at the compressor outlet fitting through all pneumatic connections. If no leaks are found and the flow is still fluctuating, replace the regulator. If the pressure at the test point is within the specified range, replace the flowmeter. Also, if low flow conditions persist, replace the outlet HEPA filter if it's dirty or plugged.

What to do if Invacare Medical Equipment has power loss and P.C. board issues?
- C
  Christy LaneSep 1, 2025
  If your Invacare Medical Equipment has a power loss, indicated by both the red and green internal status indicators being off, and the unit is plugged in but the alarm is off with a drained battery-free circuit, the P.C. board might be damaged or have a loose connector. Replace the P.C. board if damaged, and repair or replace any loose or damaged connectors.

What causes high pressure in Invacare Perfecto 2 SeriesIRC5PO2AW Medical Equipment?
- G
  goodselenaSep 3, 2025
  If your Invacare Medical Equipment shows a high pressure issue, indicated by one red flash and two green flashes on the internal status indicators, a continuous alarm, and the compressor shutting down, the P.C. board or 4-way valve may be the cause. Set the flow to the maximum L/min for the concentrator and check the voltage across Pilot Valve 1. If the meter reads 0 volts when the unit is turned on, replace the P.C. board. Check the spade connectors on pilot valves 1 or 2 and connectors on the P.C. board. Also, check the 4-way valve by checking the voltage. If the voltage rises to approximately 24 volts D.C. when the unit shuts down, the P.C. board is functioning properly; replace the valve if shorted or open. Ensure the coil reads 175 ohms ± 20.

What to do if Invacare Perfecto 2 SeriesIRC5PO2AW Medical Equipment indicates defective parts?
- L
  Lisa PatelSep 6, 2025
  If your Invacare Medical Equipment is displaying defective parts, indicated by specific red and green internal status indicator patterns, a continuous audible alarm, and the compressor shutting down, check the main valve coil and P.E. valve coil. Replace the main valve or main valve coil if defective. Reattach any loose connectors. Replace the P.E. coil if it's shorted or open on a resistance check, and replace the P.E. valve if defective. If these steps don't resolve the issue, the P.C. board may be defective and need replacement.

Why is my Invacare Medical Equipment not operating with a continuous alarm?
- I
  iwillisSep 8, 2025
  If your Invacare Medical Equipment is not operating, with both red and green internal status indicators off, all control panel indicators off, the power switch on, and a continuous audible alarm sounding, the transformer assembly might be the issue. Reattach the assembly connector if it's disconnected, or replace the transformer assembly if it's faulty.

What causes internal power loss in Invacare Perfecto 2 SeriesIRC5PO2AW?
- S
  Stephanie HaleSep 10, 2025
  If your Invacare Medical Equipment is showing internal power loss, indicated by both red and green internal status indicators being off, and the alarm may or may not be on, the transformer assembly may be faulty. Replace the transformer if it is faulty, reattach any loose or disconnected connectors, or replace the transformer assembly if the wiring is faulty.
