A unit that has just been installed, or a room that has just been re-floored, can produce a complaint about an appliance that has not changed at all. ### The maker names two causes, and they are both free U-Line’s own troubleshooting table gives exactly two reasons a unit is noisy: refrigeration tubing touching the cabinet, which is repositioned, and a fan blade obstructed by wiring, foam insulation or packaging material, which is removed. A useful number of these calls end without a part. ### And a list of what is supposed to happen The manual also publishes what these appliances sound like when they are working, which is unusually candid. Hard floors, tiled walls and a run of cabinetry reflect all of it, so a unit that has not changed can become a complaint after a room has been re-floored. Refrigeration tubing touching the cabinet The maker's own first cause, and the answer is to reposition it carefully rather than to replace anything. Something against a fan blade The maker's second cause: wiring, foam insulation or packaging material. Free to fix and alarming to listen to. A fan motor bearing Gets louder over months and is worst just after the unit starts. A real part, and a straightforward one. The unit not sitting level A built-in appliance that is resting on three of its four feet will pass vibration into the joinery, which then does the amplifying. An auger, on a nugget machine The one noise on this list that should stop you using the appliance. A grinding or laboring sound from a nugget machine is a gearbox in trouble. Find out when it is loudest Just after starting, all the time, or only during defrost. Each points somewhere different. Check the unit is level and not touching A built-in appliance resting on three feet, or pressed against joinery, passes vibration into the cabinetry, which does the amplifying. Compare against what is normal The manual lists it: a compressor hum, refrigerant like boiling liquid, air through the condenser, water dripping into the drain pan during defrost. On a nugget machine, stop it Grinding or laboring is the auger, and continuing to run it damages the gearbox behind it. The maker names two causes, and lists what is normal What it usually means A new noise that was not there before Loudest just after it starts A rattle rather than a hum Find out whether it is a noise or the noise Hard floors, tiled walls and a run of cabinetry reflect appliance sound, and the manual says so outright.

Then look at levelling and contact first. A new appliance in an existing opening often ends up touching something it should not. ### It sounds like running water. That is on the maker's own list of normal sounds — refrigerant moving through the evaporator, and melt water reaching the drain pan during defrost. --- **[Read full article: Loud or unusual noise](https://ulinemiami.support/symptoms/loud-or-unusual-noise/)**
