We've sold over 300 residential DX2W modules over the last decade within Atlantic Canada, British Columbia and across the USA.  If you have one of these older units or are servicing one we can offer you OEM replacement parts directly from our on-line inventory.  Controls and sensors are covered for the first two years under parts replacement warranty but must be purchased after this period is over.  Most units sold come with spare temperature sensors so check to see if there are any in the cabinet before ordering more.
