DISCLAIMER - PLEASE READ: In an extended effort to ensure that the parts we ship to you are in a confirmed working condition when they leave our store, our HVAC techs have personally tested this board and verify that it is leaving our premises in good working condition. Because of this we do not accept "Warranty Returns" on this item.
To the same end we must insist the method of shipment of this part must be with UPS as they provide more comprehensive tools to pursue damaged shipments versus shipping with USPS. Should you proceed to choose USPS as your method to ship this part you assume full responsibility if damage occurs during shipment. In other words, we will not cover the cost of replacement or re-shipment of a new part. We understand that shipping costs can be high and we are aware of this burden, however, to ensure these items safe arrival to you UPS insists on at least 2 inches of packing material space (packing peanuts, packing paper) around the part. Unfortunately that adds billable dimensions to the shipment but it insures no damage to such delicate parts.
To further aid in insurance of your ability to repair your furnace / AC unit, we strongly suggest getting a licensed professional to aid you in diagnosis and in installing this new part due to its delicate nature.
