Reasons Why Your Speedaire Air Compressor Will Not Start
When a Speedaire air compressor won’t start, the issue can usually be traced back to a few common causes, similar to those found with other brands. Here are some of the typical reasons why a Speedaire air compressor might not start:
| Reason | Explanation | Troubleshooting Steps |
|---|---|---|
| Power Supply Issues | The compressor may not be receiving power due to a tripped breaker, blown fuse, or incorrect voltage. | Check electrical connections, ensure the correct voltage, and reset any tripped breakers or replace fuses. |
| Pressure Switch Failure | Faulty pressure switch may not signal the motor to start. | Test the pressure switch with a multimeter and replace if necessary. |
| Faulty Motor or Start Capacitor | The motor could be damaged, or the start capacitor may fail to provide the necessary power surge. | Inspect the motor for damage and test the capacitors, replacing faulty components. |
| Thermal Overload Protection | Overheated motor triggers a switch that cuts power to prevent damage. | Allow the motor to cool and reset the overload switch. |
| Air Pressure in the Tank | Excessive pressure might trick the pressure switch into thinking the tank is full, preventing startup. | Release some air from the tank to lower the pressure. |
| Drain Valve Left Open | An open drain valve can prevent pressure buildup, misleading the pressure switch. | Ensure the drain valve is closed tightly. |
| Incorrect Adjustments or Settings | Improperly adjusted settings, including the pressure switch, can prevent starting. | Check and adjust any incorrect settings on the compressor. |
| Mechanical Issues | Internal mechanical problems, such as seized pistons or damaged valves, can prevent starting. | Internal mechanical issues often require professional assessment and repair. |
Always consider safety first and consult the user manual or a professional if you’re unsure about performing any of these steps.
Other Speedaire Air Compressor Concerns
Beyond the common start-up issues, Speedaire air compressors can encounter other problems during their operation. Here’s a list of other potential issues and their troubleshooting tips:
Compressor is Overheating
- Causes: Lack of ventilation, high ambient temperatures, or continuous use beyond the duty cycle.
- Troubleshooting: Ensure adequate airflow around the compressor, avoid operating it in extremely hot environments, and adhere to the recommended duty cycle to prevent overheating.
Low Air Pressure or Air Flow
- Causes: Air leaks, clogged filters, or incorrect settings.
- Troubleshooting: Check for and repair any leaks. Clean or replace air filters. Adjust regulator settings for proper air flow and pressure.
Excessive Moisture in Compressed Air
- Causes: High humidity, lack of adequate moisture traps or dryers in the system.
- Troubleshooting: Install a moisture trap or an air dryer in the air line. For areas with high humidity, consider using a refrigerated air dryer to reduce moisture in the air lines.
Unusual Noise or Vibration
- Causes: Loose components, worn belts, or internal damage.
- Troubleshooting: Tighten any loose nuts or bolts. Inspect and replace worn belts. Check for signs of wear or damage to internal components and repair or replace as necessary.
Air Compressor Leaks Oil
- Causes: Worn seals or gaskets, overfilling, or a cracked case.
- Troubleshooting: Check oil levels to ensure they’re not above the recommended level. Replace worn seals or gaskets. Inspect the compressor for cracks and repair or replace parts as needed.
Pressure Relief Valve Releases Air
- Causes: Excessive pressure build-up beyond what the compressor is designed to handle.
- Troubleshooting: Check the pressure settings and adjust them if they’re set too high. Inspect the compressor’s operation to ensure it’s cycling off as it should. Replace the pressure relief valve if it’s faulty.
Air Compressor Will Not Stop Running
- Causes: Leaks in the system, faulty pressure switch, or the compressor is unable to reach cut-out pressure.
- Troubleshooting: Check for leaks in the air system and repair them. Test the pressure switch and replace it if necessary. Ensure the compressor can reach the designed cut-out pressure; if not, there may be an issue with air flow or internal damage.
Rapid Cycling
- Causes: Air leaks, too small of an air receiver tank, or a faulty pressure switch.
- Troubleshooting: Identify and repair any leaks. Consider upgrading to a larger air receiver tank if the current one doesn’t meet your air demand. Test and replace the pressure switch if it’s not functioning properly.
Remember, regular maintenance is key to preventing many common and additional problems. Always refer to the manufacturer’s manual for specific guidance on maintenance routines and troubleshooting steps tailored to your specific model.
Reader Questions & Responses
What routine maintenance should I perform on my Speedaire air compressor?
Regular maintenance is crucial for the longevity and efficiency of your Speedaire compressor. This includes draining the tank of moisture after each use, checking and replacing air filters as needed, inspecting hoses and connections for leaks or wear, and changing the oil (for oil-lubricated models) according to the manufacturer’s guidelines. Also, regularly check the belts and tighten them if they’re loose.
Can I use an extension cord with my Speedaire compressor?
It’s generally recommended to plug the compressor directly into a wall outlet to prevent voltage drop, which can damage the motor. If an extension cord is necessary, use the shortest possible length and ensure it’s of a suitable gauge to handle the compressor’s power requirement.
How often should I change the oil in my oil-lubricated Speedaire compressor?
The frequency of oil changes depends on usage. For heavy use, changing the oil every 3 months or according to the operational hours specified in the manual is recommended. For lighter use, once a year may suffice. Always use the type of oil recommended by the manufacturer.
