  Kimberly RiceAug 9, 2025
  If the drain timer on your Ingersoll-Rand Air Compressor isn't working, here's what might be happening and how to address it: 1. **No electrical supply:** Ensure the unit is receiving power. 2. **Timer malfunction:** The timer itself may be faulty and need replacement. 3. **Clogged port:** A blocked port can prevent operation; try cleaning the valve. 4. **Solenoid valve malfunction:** The solenoid valve could be defective, requiring replacement. 5. **Clogged strainer:** A blocked strainer may be the issue; clean the strainer.

Why won't the solenoid condensate valve close on my Ingersoll-Rand SSR UP6-7.5?

  Courtney RodriguezAug 16, 2025
  If the solenoid condensate valve on your Ingersoll-Rand Air Compressor won't close, it could be due to a couple of reasons. First, debris might be preventing the diaphragm from seating properly; in this case, you should remove the solenoid valve, disassemble it, clean all the parts, and then reassemble it. Alternatively, there could be a short in an electrical component. Check the power cord or timer and replace them if necessary.

  Jocelyn BrownAug 25, 2025
  If the timer on your Ingersoll-Rand Air Compressor won't activate, there are several potential causes. First, ensure that the unit is receiving electrical power by verifying the power supply. If power is present, the timer itself may be malfunctioning and require replacement. Additionally, a clogged port or strainer could be preventing activation; try cleaning the valve and strainer. Finally, a malfunctioning solenoid valve could be the culprit, in which case it should be replaced.

  Angela OconnorAug 30, 2025
  If the valve on your Ingersoll-Rand Air Compressor won't close, it could be due to debris in the solenoid valve preventing the diaphragm from seating properly. To resolve this, remove the solenoid valve, disassemble it, thoroughly clean all components, and then reassemble it. Alternatively, a short in an electrical component, such as the power cord or timer, could be the cause. Inspect these components and replace them as necessary.
