This replacement fuse assembly protects the appliance's power circuit by opening when an overcurrent or short occurs. Installing a new fuse assembly after a failure helps restore power and safeguard sensitive wiring and electronics. What it does:

  • Interrupts electrical flow if current exceeds a safe threshold
  • Helps protect wiring, control boards, and other components from damage
  • Common symptoms: appliance completely dead/no lights, won't start or respond to controls, fuse tests open or repeatedly blows
What's included:
  • 1 fuse assembly
Install notes:
  • Disconnect power at the breaker before servicing; verify zero voltage before touching wiring
  • Match the exact part number and electrical rating specified for your model—do not upsize a fuse
  • Identify and correct the underlying cause of the blown fuse (shorted component, pinched wire) before restoring power
  • Some appliances contain capacitors that can hold a charge; follow the service manual to discharge if applicable
