Limited Warranty

Loren Cook Company warrants that your Loren Cook fan was manufactured free of defects in materials and workmanship, to the extent stated herein.  For a period of one (1) 

year after date of shipment, we will replace any parts found to be defective without charge, except for shipping costs which will be paid by you.

This warranty is granted only to the original purchaser placing the fan in service.

This warranty is void if the fan or any part thereof has been altered or modified from its original design or has been abused, misused, damaged or is in worn condition or if the 

fan has been used other than for the uses described in the company manual.  This warranty does not cover defects resulting from normal wear and tear.

To make a warranty claim, notify Loren Cook Company, General Offices, 2015 East Dale Street, Springfield, Missouri 65803-4637, explaining in writing, in detail, your 

complaint and referring to the specific model and serial numbers of your fan.  Upon receipt by Loren Cook Company of your written complaint, you will be notified, within thirty 

(30) days of our receipt of your complaint, in writing, as to the manner in which your claim will be handled.  If you are entitled to warranty relief, a warranty adjustment will be 

completed within sixty (60) business days of the receipt of your written complaint by Loren Cook Company.

This warranty gives only the original purchaser placing the fan in service specifically the right.  You may have other legal rights which vary from state to state.

For fans provided with motors, the motor manufacturer warrants motors for a designated period stated in the manufacturer’s warranty.  Warranty periods vary from 

manufacturer to manufacturer.  Should motors furnished by Loren Cook Company prove defective during the designated period, they should be returned to the nearest 

authorized motor service station.  Loren Cook Company will not be responsible for any removal or installation costs.
