The main point of investing in a phase converter is to know that you have reliable power on hand whenever you need it. Unfortunately, phase converters can experience malfunctions from time to time that interrupt the power supply. Unless you’re a phase converter expert, you probably don’t know how to address even the most common issues that cause them to malfunction.
That’s where we come in. The Phoenix Phase Converters team is here to help you troubleshoot your phase converter so you can enjoy continuous power during every project. Keep reading for some basic tips and tricks.

The Phase Converter Motor Doesn’t Start
If your phase converter won’t start from the get-go, you have one of two situations on your hands. Either the unit doesn’t make a noise and won’t start, or it makes a noise but doesn’t start. Here’s what you should check for when this happens.
The converter doesn’t start and produces no sound:
- Ensure the motor is within the horsepower range of the phase converter.
- Double-check that the motor’s voltage requirement matches that of the phase converter.
- Ensure enough power is being generated to support the phase converter.
- Check the motor controls for proper wiring.
- Check the fuses and heaters for correct sizing.
The converter makes a sound but doesn’t start:
- Ensure the toggle switch is turned on.
- Check the fuses and breakers to ensure proper function.
- Check for any bad connections and loose wires in your phase converter. Tighten connections and wires as needed. Also check for crossed wires between the motor and the unit.
- Ensure the wiring is installed and connected properly. Check the owner’s manual for a diagram of what it should look like. Contact the manufacturing company for assistance or clarification if needed.
- Check for any internal damage to phase converter components.
The Phase Converter Is Vibrating Excessively or Making a Loud Noise
A common reason that phase converters vibrate excessively or make high-frequency noises is that the surface on which the unit is mounted doesn’t offer adequate support.
Excessive Vibration
While some vibration is normal, excessive vibration may point to an underlying problem. Below are a few potential phase converter problems and how to address them.
- Improper Mounting: Check the owner’s manual that came with your phase converter to find helpful mounting correction tips. Many owners’ manuals recommend mounting phase converters on the wall. You might need to install mounting rails on the bottom of the unit or rest the motor on a supportive rubber pad for added stability. Ensure the phase converter is secure after each step, but don’t bolt it to the surface.
- Isolation Issue: Phase converters should be kept far away from dirt, dust, oil, and other contaminants that could clog their internal components and halt operation. Unless your unit is resistant to these things, keep it isolated from them.
- Overloading Issue: When phase converters become overloaded with the power demand, they can malfunction and even shut down altogether. Overloading can occur when the phase converter’s specifications are incompatible with the machine itself. Make sure the specifications are compatible with the phase converter. If the problem persists, you might need a larger unit that can accommodate more power.
Excessive Noise
Below are some common noises that malfunctioning phase converters make and tips for stopping them.
Grinding or Growling
- Open Circuit: Check the fuses, breakers, starters, and switches for an open circuit.
- Incorrect Wiring: Make sure the wiring is installed and functioning properly.
- Excessive Load: Ensure your phase converter can handle the power load placed on it.
Humming or Chattering
Consistently low voltage means the phase converter is too small for the application. Switch out the phase converter for a more accurate size. Need help? Contact Phoenix Phase Converters for expert help with phase converter sizing.
The Fuses & Circuits Are Blowing
When the fuse blows or the circuit breakers trip immediately after the phase converter begins operating, you likely have a short circuit on your hands. Check the circuit for any loose wires or broken connections. Contact an electrician if repairs or replacements are needed.
When the fuse blows or the circuit breakers trip occasionally or continuously—but not instantly—when the phase converter operates, the cause is the wrong size wiring, fuse, or breaker. Make sure the wiring, fuses, and breakers are sized correctly. If they aren’t, you should replace them.
Common Voltage Problems With Three-Phase Converters
The most common voltage problem with single phase to 3 phase converters is it being too low or too high. Make sure the voltage requirements align with those of the phase converter. You might need to replace the wiring with a different size or disconnect some capacitors to balance it out.
