Maintenance Tips

Keep the heater cabinet sealed and dry—moisture is a common cause of corrosion and electrical faults that can blow fuses.
If fuses fail repeatedly, inspect for rubbed-through wires, rodent damage, loose terminals, or failed components before replacing more fuses.
Maintain proper flow (clean baskets/filters) to avoid nuisance faults that can stress electrical components.
