The search is enormous and the answer is one sentence long, which is presumably why so few pages give it. What people mean when they search for it is one of three things, and they have very different consequences. ## One: a power cycle This is the reset that exists. **Off at the breaker or the plug, wait five minutes, back on.** Five minutes rather than five seconds — a compressor that has just stopped is sitting against a head of pressure and needs the system to equalize before it can start again. Switching straight back on can put it into its own overload, which then locks it out for longer than you waited. On a built-in appliance you will be doing this at the panel rather than at the plug, because the outlet is behind the unit and the unit is in the joinery. That is normal on this make. ## Two: the two modes that are not failures Before cycling power, spend ten seconds on these, because a power cycle does not clear either of them and people spend real money finding that out. **Showroom mode.** The maker's own description: the degree symbol flashes, the display is lit, the interior light works, and the unit will not cool. It exists so a dealer can stand a machine on a floor and demonstrate it. Floor models get sold, so units arrive in it. Hold the light key and the power key together for five seconds; the display flashes once and beeps. **Sabbath mode.** Display and cabinet lights dark, refrigeration running normally, and on the current controls every alarm silenced as well. Hold the light key for five seconds on the older controls, or any control button for three seconds on the current ones. Between them these account for a real share of the calls that arrive on this site described as a dead appliance. ## Three: the service menu, and the thing not to do in it The hidden button held for ten seconds puts the control into service mode; the display shows 0. Inside are the parameters the appliance runs on — defrost interval, defrost duration, evaporator fan delays, sensor offsets, compressor RPM — plus two entries that look like resets. **Factory defaults** restores every parameter for whichever model number the board is programmed to. That is a genuine tool and it has a genuine trap: every U-Line control carries a two-digit model number and reads its timings from it. A replacement board that was fitted and never programmed will restore *another machine's* settings, quite happily. **Clear error log** is the one to leave alone. ## Why clearing the log is expensive U-Line writes the same sentence in every manual that carries a code table: all errors are logged in memory, and only the door error is displayed and has an audible signal. Read that twice, because it decides everything about diagnosing one of these. **The appliance knows what went wrong. It wrote it down. It has no way of telling you.** The only copy is in that log, in the order the errors happened, and the order is often the whole story — a door error followed by a thermistor error is a different afternoon from a thermistor error on its own. Clearing it takes five seconds and deletes all of that. If you have called somebody out, the log is the first thing they will want, and arriving to find it cleared puts the visit back to guessing. ## What a reset actually tells you A reset is a test, and the result is which branch you land on. - **The problem is gone and stays gone.** Something transient — a brownout, a control that latched, a door switch that stuck once. Worth noting the date and moving on.- **The problem returns within the hour.** Whatever is wrong is still wrong. A reset has told you it is not a one-off, which is genuinely useful information.- **The problem returns in a few days.** The hardest pattern and the most common on failing sensors and door switches. Write down when it happens and what the cabinet was doing. ## When a reset is the wrong move - **When there is a number on the display.** Photograph it first. On this make that is a rare and valuable thing to have.- **When the machine is an ice machine that has stopped and there is standing water.** Cycling power on a machine with a drain problem just runs the cycle again.- **When a nugget machine is making a grinding noise.** Switch it off and leave it off. The auger is being driven against something solid, and every additional minute is gearbox. ## And what to have ready if it comes back The model and serial from the plate on the upper right or the rear wall inside, whatever the display showed before you touched anything, and how long the reset held. That is more than most people arrive with, and on an appliance that hides its own diagnostics it is worth a great deal. --- **[Read full article: How to Reset a U-Line — and Why There Is No Reset Button](https://ulinemiami.support/blog/how-to-reset-a-u-line-ice-maker-or-wine-cooler/)**
