General Questions

How long does it take to get my order ship?
Orders are typically processed and packaged for shipment within a 24 to 72 hour time period. Your package should then take the number of days corresponding to your choice of the shipping method to arrive at your location. Please note that we do not ship out during the weekends, as FedEx does not normally do weekend deliveries. If you absolutely need an item to arrive during the weekend, a Saturday Delivery charge may be incurred for a weekend delivery.

What is EEE Code and is this the right parts for my system?
The best way to find out if this is the correct part for you is to match up the EEE code on your part serial number, NOT the serial number of the machine. The part serial number is on a tag which has the format "xxxxxxxEEEE". The "EEE" code is the last three or four letters or digits of the serial number.
