rjh914 Posted February 3, 2017 Share Posted February 3, 2017 Today I looked a Dixie Narco 276E for a new location. It is in very good condition at a good price...a good cleaning and I can deploy it. However, I noticed some ice build up on the top half of the refrigeration deck. I asked the seller about it. He said that he noticed the same thing about a year before. He unplugged it to let it thaw out, then plugged it back in. Is this definitely a sign of a compressor deck problem or could it be something simple like the thermostat being set too high, etc. Thanks in advance!

Chard Posted February 3, 2017 Share Posted February 3, 2017 Could be an air leak, low freon or a bad temperature control. Sent from my SGH-M919 using Tapatalk Link to comment Share on other sites More sharing options...
AZVendor Posted February 3, 2017 Share Posted February 3, 2017 Probably low on freon. Link to comment Share on other sites More sharing options...
CajunCandy Posted February 3, 2017 Share Posted February 3, 2017 A tad low on freon. Link to comment Share on other sites More sharing options...
Vendors Tech Posted February 3, 2017 Share Posted February 3, 2017 If it's low, chances are you have a slow leak, so be sure to check for that, or have your refrig guy check for it. Your cut-in cut-out setting on your thermostat may be set wrong, or the thermostat could not be functioning properly as well. I have also seen a clogged drain or unlevel machine cause ice buildup because the water never gets out of there. Link to comment Share on other sites More sharing options...
Snickers Posted February 5, 2017 Share Posted February 5, 2017 We have a 501E that makes a ton of water. It has an ice cream pail for the drain hose to go into because it makes so much water and it has to be emptied on each visit. The door seal and inner door are in excellent shape,the door flap is intact and clean I'm not sure what else to look for to help this problem? Any ideas?

AngryChris Posted February 5, 2017 Share Posted February 5, 2017 You need to check if there are any visible signs of moisture on the outside of the door seal AND the delivery door. Also, how long between visits? It's possible you just need sponges. You do NEED sponges in your water pan to help the water evaporate. Link to comment Share on other sites More sharing options...
Vendors Tech Posted February 6, 2017 Share Posted February 6, 2017 Refrigerated machines can't manufacture water - it has to come out of the air let in when you have the door open, or from moisture on the product you put in it. If you're getting a pail full of water, there is no way you could let that much moist air in just by opening the door. Even if you think the door is sealing good, I would replace the seal anyway. They are not that hard to replace, and they are cheap (relatively speaking). I can't think of any other way for that much air to get into the machine if the seal wasn't bad. The OEM evap pan should be able to handle the water that normally comes down if everything is sealed right, even without sponges. Link to comment Share on other sites More sharing options...
Snickers Posted February 7, 2017 Share Posted February 7, 2017 The seal doesn't look bad as it's not torn or sagging but I guess it could still be bad. We have several machines out there that don't do this and most don't have the sponges. I will look at replacing the seal. Thanks Link to comment Share on other sites More sharing options...
AngryChris Posted February 7, 2017 Share Posted February 7, 2017 In all honesty, the easiest thing to do is to check to see if you can find condensation on the outside ANYWHERE on the machine. I had a machine where the tank had corroded near the rear so bad, the water would build up and travel toward the back of the cabinet and out through a pin hole and leak on the floor, completely bypassing the drain... all because of the buildup of crap at the bottom of the tank. When I cancel that account, the machine is getting parted out and sent to the scrap yard. The point is that you need to look for signs of an air leak, which is usually condensation if the environment is humid around it. In all fairness, you should only get that much condensation if there's a lot of relative humidity around it, and it should only get into the machine if there's an air leak. The two most common places to find an air leak is around the perimeter of the door seal (make sure the seal is CLEAN too, and check the TOP) and the delivery door. Sometimes, delivery doors don't close all the way and you'll find water all around the delivery door. P.S. I would double and triple check the delivery door to see if it hangs up at all. I had a machine do that until I figured out the problem and fixed it. Link to comment Share on other sites More sharing options...
Snickers Posted February 12, 2017 Share Posted February 12, 2017 Sure enough after closer inspection the door seal on the bottom was sagging from it being torn where the screws are. Enough to not give the proper seal and allow outside air in. Link to comment Share on other sites More sharing options...
AZVendor Posted February 12, 2017 Share Posted February 12, 2017 Just loosen the screws on both sides of the inner door's lower edge, tuck the seal up under the screws and tighten them again. Make sure you clean all syrup off the seal and the front edge of the tank or you'll rip it loose again. Sticky syrup on that edge is always the cause of a torn seal.
