Safe checks, in order
Start with the simplest non-invasive check. Stop as soon as the error clears; repeated resets can hide a condition without correcting it.
Stop the cycle
Allow the appliance to cool before touching any accessible area.
Check normal airflow or flow
Clean only the filters and vents identified for routine owner maintenance.
Confirm the power supply
Check for a tripped breaker without repeatedly resetting it.
Request diagnosis
Heating circuits require model-specific electrical testing.
Know where to stop
Heating faults can involve hot water, steam, or line voltage. Do not access heaters, relays, or internal wiring.
When to call a technician or support
Use a qualified technician when a heating code appears more than once or the appliance overheats.
When you call, have the exact product model, the complete code or light pattern, and when it appeared.
