Safety first: Turn off power and wait for the motor to stop completely before inspection.

Inspect fan and shroud: Remove the rear cover and check the cooling fan for broken blades or rubbing against the shroud.
Remove debris: Clear any leaves, twigs, or foreign objects from the fan area.
Tighten shroud: Secure the fan cover with the correct screws so it does not contact the fan.
Replace fan: If blades are broken or the fan is loose on the shaft, replace the fan with a Franklin Electric-compatible part.
