To fix a Dyson heater not turning on, check the power source, ensure the safety cutout isn’t triggered, and inspect for any error codes or blockages.
When your Dyson heater fails to turn on, it can be frustrating. This guide provides step-by-step solutions to diagnose and fix common issues preventing your Dyson heater from powering up.
Check Power Source And Connections
Start with the most basic troubleshooting steps before moving to complex solutions.
Verify Power Outlet Functionality
Test the outlet with another device to confirm it’s working. Try plugging your Dyson heater into a different outlet. Check for tripped circuit breakers or blown fuses in your electrical panel.
Inspect Power Cord And Plug
Examine the entire length of the power cord for damage. Look for frayed wires, bent prongs, or burn marks. If you find damage, consider replacing the power cord assembly.
Perform A Hard Reset
Many Dyson heater issues can be resolved with a proper reset procedure.
Standard Reset Process
- Unplug the heater from the power source
- Wait at least 30 seconds
- Plug the unit back in
- Press and hold the power button for 10 seconds
Factory Reset For Persistent Issues
For models with persistent problems, perform a factory reset:
- Turn off and unplug the unit
- Press and hold the power button for 20 seconds
- Plug the unit back in while continuing to hold the button
- Release after 5 more seconds
Clean And Maintain Your Heater
Proper maintenance often resolves operational issues.
Filter Cleaning And Replacement
Clogged filters are a common cause of heater malfunctions. Remove and inspect the filter according to your model’s instructions. Clean reusable filters with cold water and let them dry completely. Replace disposable filters if they appear dirty or damaged.
Internal Component Cleaning
Use a soft brush to remove dust from internal components. Clean the air intake and exhaust vents with compressed air. Wipe down the exterior with a damp cloth.
Check Thermostat And Temperature Settings
Incorrect settings can prevent proper operation.
Verify Temperature Selection
Ensure the thermostat is set to a temperature higher than the current room temperature. Check that the heater is in heating mode (red indicator light on most models).
Test Auto Mode Functionality
Switch between manual and automatic modes to test responsiveness. If the heater works in manual mode but not auto, there may be a sensor issue requiring professional service.

Dyson heaters display specific error codes for different issues.
| Error Code | Meaning | Solution |
