Avoid Tekniton Like the Plague!
FREMONT, CALIFORNIA -- Samsung referred me to Tekniton when my 3 yr old Samsung refrigerator/freezer was making loud noises when the refrigerator door was closed. Tekniton said they would come out for $90.00 and based on the problem I described the total service call would be just under $300. I thought I could get the work done for less so I called Van Deutch Appliance Repair and was told that based on when the sound occurs and what it sounds like, it is probably just caused by ice build up.
They told me to defrost the entire unit for 8 hours and it should work just fine. And YES it did. They saved me $300 or more that Tekniton may have ended up charging me. I would avoid Tekniton like the plague.
