 (“Seller”) warrants to the first retail purchaser of this product, for the residence in which this product is originally 

installed, that it is free from defect in materials and/or workmanship for a period of one year from the date of purchase [and that 
the motor is free from defect in materials and/or workmanship for a period of four years from the date of purchase]. The proper 
operation of this product is dependent on your compliance with the instructions regarding installation, operation, maintenance 
and testing. Failure to comply strictly with those instructions will void this limited warranty in its entirety.

If, during the limited warranty period, this product appears to contain a defect covered by this limited warranty, call 1-888-528-
6306, toll free, before dismantling this product. Then send this product, pre-paid and insured, to our service center for warranty 
repair. You will be advised of shipping instructions when you call. Please include a brief description of the problem and a dated 
proof-of-purchase receipt with any product returned for warranty repair. Products returned to Seller for warranty repair, which 
upon receipt by Seller are confirmed to be defective and covered by this limited warranty, will be repaired or replaced (at Seller’s 
sole option) at no cost to you and returned pre-paid. Defective parts will be repaired or replaced with new or factory-rebuilt parts 
at Seller’s sole option.

ALL IMPLIED WARRANTIES FOR THE PRODUCT, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF 
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO THE ONE YEAR 
LIMITED WARRANTY PERIOD SET FORTH ABOVE [EXCEPT THE IMPLIED WARRANTIES WITH RESPECT TO THE 
MOTOR, WHICH ARE LIMITED IN DURATION TO THE FOUR YEAR LIMITED WARRANTY PERIOD FOR THE MOTOR], 
AND NO IMPLIED WARRANTIES WILL EXIST OR APPLY AFTER SUCH PERIOD.  Some States do not allow limitations 
on how long an implied warranty lasts, so the above limitation may not apply to you. THIS LIMITED WARRANTY DOES 
NOT COVER NON-DEFECT DAMAGE, DAMAGE CAUSED BY IMPROPER INSTALLATION, OPERATION OR CARE 
(INCLUDING, BUT NOT LIMITED TO ABUSE, MISUSE, FAILURE TO PROVIDE REASONABLE AND NECESSARY 
MAINTENANCE, UNAUTHORIZED REPAIRS OR ANY ALTERATIONS TO THIS PRODUCT), LABOR CHARGES FOR 
REINSTALLING A REPAIRED OR REPLACED UNIT, REPLACEMENT OF BATTERIES AND LIGHT BULBS OR UNITS 
INSTALLED FOR NON-RESIDENTIAL USE.

THIS LIMITED WARRANTY DOES NOT COVER ANY PROBLEMS WITH, OR RELATING TO, THE GARAGE DOOR OR 
GARAGE DOOR HARDWARE, INCLUDING BUT NOT LIMITED TO THE DOOR SPRINGS, DOOR ROLLERS, DOOR 
ALIGNMENT OR HINGES. THIS LIMITED WARRANTY ALSO DOES NOT COVER ANY PROBLEMS CAUSED BY 
INTERFERENCE. ANY SERVICE CALL THAT DETERMINES THE PROBLEM HAS BEEN CAUSED BY ANY OF THESE 
ITEMS COULD RESULT IN A FEE TO YOU. 

UNDER NO CIRCUMSTANCES SHALL SELLER BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL OR SPECIAL 
DAMAGES ARISING IN CONNECTION WITH USE, OR INABILITY TO USE, THIS PRODUCT. IN NO EVENT SHALL 
SELLER’S LIABILITY FOR BREACH OF WARRANTY, BREACH OF CONTRACT, NEGLIGENCE OR STRICT LIABILITY 
EXCEED THE COST OF THE PRODUCT COVERED HEREBY. NO PERSON IS AUTHORIZED TO ASSUME FOR US ANY 
OTHER LIABILITY IN CONNECTION WITH THE SALE OF THIS PRODUCT.

Some States do not allow the exclusion or limitation of consequential, incidental or special damages, so the above limitation or 
exclusion may not apply to you. This limited warranty gives you specific legal rights, and you may also have other rights which 
vary from state to state.
