A fog machine is a fantastic way to create spooky, dramatic, or atmospheric effects, whether for Halloween, a party, or a stage performance. But what happens when your fog machine stops working right when you need it most?
If you’re wondering “Why is my fog machine not working?”—you’re not alone. Many users experience common problems like heating issues, pump failures, remote malfunctions, and fuse blowouts. The good news? Most of these problems have simple fixes!
In this guide, I’ll walk you through the most common fog machine issues and how to troubleshoot them—so you can get back to creating an eerie, misty ambiance in no time.
1. Fog Machine Heating Up But Not Working
If your fog machine is heating up but not producing fog, it could be due to a clog, a faulty thermostat, or an empty fluid tank. Here’s what to check:
- Is there fog juice in the tank? Low or empty fog fluid will prevent fog production.
- Is the nozzle clogged? Mineral buildup from fog juice can block the nozzle over time. Try cleaning it with a mixture of vinegar and water.
- Is the machine fully heated? Some machines take 5–10 minutes to warm up. If it’s flashing but not working, it may still be in the heating phase.
Fix:
- Turn off the machine and let it cool.
- Clean the nozzle with a vinegar-water solution.
- Check if the fog juice is low—if so, refill.
- Restart and allow full heating before testing again.
2. Fog Machine Pump Not Working
If your fog machine turns on but won’t push out fog, your pump may be the issue. A clogged or broken pump can prevent the machine from drawing in fog fluid.
Symptoms of a Faulty Pump:
- The machine hums but doesn’t spray fog.
- No fluid moves through the tubes.
- You hear a clicking noise but no fog appears.
How to Fix It:
- Check for blockages: Remove and clean the pump tubing with warm water.
- Prime the pump: Try running a small amount of warm water through it to dissolve any dried fog fluid.
- Replace the pump: If the pump is still unresponsive, it may need replacing. Search for “fog machine repair near me” to find a professional technician.
3. LED 500 Fog Machine Not Working
The LED 500 fog machine is a popular model, but like any device, it can run into problems. If yours isn’t working, try these steps:
- Check the power source. Ensure it’s plugged in and the outlet is functioning.
- Inspect the fuse. A blown fuse can cause a complete shutdown. Look at the manual for fog machine fuse replacement instructions.
- Confirm the remote is working. If using a wireless remote, check the battery.
If your LED 500 fog machine is not working after trying these, a factory defect may be the issue. Contact the manufacturer for support.
4. Fog Machine Remote Not Working
Most fog machines come with a wired or wireless remote, and if it stops working, the machine won’t trigger fog output.
Troubleshooting Steps:
- For wireless remotes:
- Check and replace the batteries.
- Make sure the remote and receiver are properly paired.
- For wired remotes:
- Inspect the connection—loose cables can prevent communication.
- Try another compatible remote if available.
If the fog machine remote is not working, you can manually trigger the machine using the manual fog button (if available).
5. Spirit Halloween Fog Machine Not Working
Spirit Halloween fog machines are popular for haunted houses, but if yours isn’t working, check these common issues:
- Clogged nozzle – Clean it with vinegar and water.
- Low fluid – Refill with high-quality fog juice.
- Faulty power supply – Try another outlet or check for a blown fuse.
Pro Tip:
Spirit Halloween machines are known for occasional overheating. If it shuts off unexpectedly, let it cool down before trying again.
6. Fog Machine Fuse Replacement
If your fog machine won’t turn on at all, a blown fuse is a likely culprit.
How to Replace a Fog Machine Fuse:
- Unplug the machine and let it cool down.
- Locate the fuse compartment (usually near the power cord).
- Remove the old fuse and check for visible damage.
- Replace it with a new fuse of the same type.
- Plug it back in and test the machine.
If your machine still doesn’t work, the issue may be deeper—like a burned-out heating element or damaged wiring.
7. Fansteck Fog Machine Not Working
Fansteck is a budget-friendly brand, but if your Fansteck fog machine is not working, try these fixes:
- Check the power source. Ensure the outlet and power cable are working.
- Test the remote. If unresponsive, try replacing the battery.
- Flush the pump. Run warm water through the pump to clear blockages.
If the machine still won’t work, you may need to contact Fansteck support for a replacement.
8. Brand New Fog Machine Not Working
Nothing is more frustrating than a brand new fog machine not working straight out of the box. If this happens:
- Check the manual – Ensure all setup steps were followed.
- Inspect the power connection – Try a different outlet.
- Let it heat fully – It may take longer to warm up on first use.
- Look for leaks or disconnected tubes.
If none of these work, the machine may be defective—contact the retailer for a replacement.

When to Seek Professional Help:

Chauvet makes high-end fog machines, but even premium brands can have issues. Here’s how to troubleshoot a Chauvet fog machine not working:

If the problem persists, Chauvet DJ support offers replacement parts and professional repair services.
