Fog machines are a popular choice for creating an eerie atmosphere during Halloween or theatrical performances. However, like any equipment, they may encounter issues that prevent them from producing fog. In this guide, we will discuss some common troubleshooting steps to help you get your fog machine up and running again.
1. Check the Pump
The pump is responsible for moving the fog fluid from the tank to the heat exchanger. If you don’t see any fog, ensure that the fluid tank isn’t empty. If the pump is making a humming sound, it is likely working, but there may be blockages. To clear blockages, consider running distilled white vinegar through the system or check for kinked hoses. If the pump isn’t working at all, you may need to replace it.
2. Inspect the Heat Exchanger
The heat exchanger heats the fog fluid and transforms it into vapor. Ensure that the heating element inside the metal block is functioning correctly. If the fog machine’s wattage is too low, it may struggle to maintain the required heat. You may need to purchase a fog machine with higher wattage for better performance.
3. Examine the Nozzle
The nozzle dispenses the superheated fog vapor. If the nozzle or its protective cover becomes extremely hot during use, allow them to cool down before attempting any repairs. Make sure the exit nozzle isn’t clogged or blocked, as this may hinder fog production.
By following these troubleshooting steps, you can address common issues with your fog machine. Regular maintenance, such as cleaning and using fog machine cleaner, can help prevent problems. Remember to consult the manufacturer’s instructions or seek professional assistance if the issue persists.
What To Do When Fog Machine Pump Not Working

Fixing a Dirty and Clogged Fog Machine Pump
When your fog machine is not working and you can hear the pump running but no fog is coming out, the issue may be a clogged pump. Here are four easy steps to unclog and clean your fog machine pump.
Step 1: Open and Remove the Cover of the Pump: To access the pump, unscrew the screws along the side of the fog machine case and lift off the cover. Once the cover is removed, you will be able to see the inner workings of the machine, including the pump and the sensors for the heater block.
Step 2: Check the Nozzle and Unclog the Pinhole: Often, clogged pumps are caused by blocked nozzles. Remove the rubber bracket holding the fog machine together and use a wrench to check if the nozzle is loose. Disassemble the device to reveal the pinhole that is causing the clog. Unclog it by poking it with a needle on both sides and soaking it in hot distilled water for a few minutes. Blow through it to ensure air flow.
Step 3: Open the Interior of the Pump: If the clog persists, remove the two screws from the cylindrical pump assembly. Check the coil inside the pump for any issues. Remove the small key groove, ensuring nothing is lost.
Step 4: Disassemble and Clean the Pumping System: Once the seal is removed, you will see the pump mechanism that moves the fog fluid. Disconnect and soak the metal component in distilled water. Tap the screen to make the small ball fall out and secure it. Remove the plastic piece and spring. Soak all the disassembled parts in cleaning solution before reinstalling them.
Fixing a Worn Out Pump in a Fog Pump Machine
When your fog machine is not working properly, one possible issue could be a worn-out pump. The pump is responsible for pumping the fog fluid from the reservoir into the heating element. If you suspect that the pump is the problem, you can follow these simple steps to fix it.
Step 1: Dismantling the Worn Out Pump: The first step is to remove the pump from the fog machine system. Disconnect the back nut attached to the output side of the pump. Cut the wires on the input side of the pump and remove the plugin for the reservoir.
Step 2: Find Materials for Repairing the Pump: Locate the necessary materials from your local hardware or auto parts store. Consider using a windshield washer pump or any other motor with a voltage difference similar to the fog machine. The intention is to correct the output voltage using a transformer.
Step 3: Correct the Output Voltage Using a Transformer: Use a transformer to convert the 120-volt alternating current from your home to 12 volts. Feed the converted voltage through a bridge rectifier to convert it to direct current. Consider replacing the circuit board if necessary.
Step 4: Modify the Pump: Connect the modified pump using a barbed fitting and tubing. Drill a hole and insert the adapter to connect the pump to the heating element of the fog machine. Secure the fittings and attachments properly.
Step 5: Design an Adapter: Tap the barbed fitting into the pump with a rubber mallet and connect the adapter to the pipe. Leave a knot in the tube to secure the compression fitting.
Step 6: Connect the Transformer to the Modified Pump: Establish a tube connection between the old and new pumps. Wire the transformer to hack the pump and replace it with the new one. Connect the output to a rectifier to reduce the voltage to 12 volts DC.
Step 7: Mount the Pump on the Fog Machine: Mount the electrical connections and transformer in empty spots within the fog machine. Use a voltage meter to ensure the correct voltage. Install the reservoir tank and test the pump motor.
When the Fog Machine Makes a Loud Noise
When the fog machine makes a loud noise, it could be due to the dispersion of fog, which is a normal trait in many fog machines. This noise is caused by the forceful release of vapor, especially in higher wattage models with greater output distances.
However, if the noise is accompanied by a chunking sound and a drastic drop or lack of fog emission, it may indicate a failing pump. In such cases, it is important to exercise caution when attempting to fix the pump, as it could void the warranty or worsen the situation. Consider reaching out to the manufacturer or nearest service center for assistance.
If the noise is simply a result of the machine’s design or power, you can try placing it further away from the action, blocking it with decoration, or even building a containment unit, while ensuring the nozzle path remains clear to prevent overheating.
There could be several reasons why your fog machine is not working. Firstly, check if the power supply is connected properly and the machine is switched on. Ensure that the fog fluid level is sufficient. If the machine has been idle for an extended period, the heater block may require a longer warm-up time.
