    Warranty & Extended Maintenance

    Each one of our products includes a one year standard warranty on all parts, labor, and shipping.

    Link4 offers comprehensive extended warranty packages that provide the grower the extra support they need to keep their facility running. Purchase a 3 year or 5-year package that will provide you services that are not provided with the standard warranty package. Link4 extended warranty packages may include:

    • Replacement parts at no cost
    • Expedited shipping.
    • Priority accessibility with our tech support staff including after hour support.
    • Extended phone support and training
    • Cloud, Linkconn or firmware updates

    Contact your Link4 representative for the full list of services with your desired warranty package.

    Link4’s Standard Warranty warrants that the goods sold will be free from defects in material and workmanship for a period of 12 months after the date of purchase. This warranty will be limited to the repair and replacement of parts. Link4 shall not be responsible for replacement(s) or repair(s), that become defective from user negligence, modification, abuse, any types of improper usage or installation, acts of God and/or force majeure.

    If the warranty lapses and there is interest to renew the warranty, a paid site visit will be required before pricing can be provided.
