HA is the high temperature alarm. With the factory settings it comes on when the cellar reads more than 10° above the setpoint for longer than a 60-minute delay, and not during the first 23 hours after start-up. Cooling carries on as before, and the alarm clears itself once the temperature comes back down. Wine-Mate wine cellar cooling unit display What to do when HA shows on the wine cellar cooling unit ### Kind of code Temperature and alarms The controller saw the cellar go past a high or low limit and raised an alarm, sometimes holding the worst reading it logged while the house was empty. The reason can be as small as the cellar door left ajar after a tasting or a long outage, a room gaining heat from new lights or a sunny glass wall, or as serious as cooling that has stopped. Keep the door shut and read a thermometer on a middle rack before touching anything; the alarm is a warning about the collection, not yet a diagnosis. ### Usually leads to Cellar cooling load and room check Measuring the cellar as the cooling unit sees it: insulation, vapor barrier, door, glass and the heat load, to show whether the unit can ever keep up. ### Shows up as Cellar Cooling Unit Error Code A cellar cooling unit error code appears as letters or digits on the controller, a flashing reading, a blinking light on the unit, or an alarm tone, sometimes while the cellar still holds its temperature. ### Make Wine-Mate Wine-Mate cooling units repaired on site when they will not start, ice over, trip a breaker or leave the walls wet. ### Source Wine-Mate HZD self-contained cooling system manual Current Wine-Mate five-button controller, as printed in the HZD, HZD-DE, 4510-series HZD, HTD, low-profile and SSH, SSD and SSO split-system manuals.

Follow it to the end: the last card says whether this is a visit. 01 Keep the cellar door shut and confirm the reading with a separate thermometer. 02 Check that the exhaust side has its 3 feet of clear space and that the condenser is not matted with dust. 03 Look at the evaporator for ice; Wine-Mate lists an iced coil among the causes of a warm cellar, and the defrost key starts a manual defrost. 04 If the room keeps climbing toward 70°F, move the most valuable bottles and book a visit. ### Still there? It usually turns into [cellar cooling load and room check](https://winecellarrepair.center/services/cellar-cooling-load-and-room-check/). Book with the code and the model number. ### What not to do HA does not mean the unit has shut down, because the outputs stay as they were. If CA is showing, or the display is dark, the unit is not cooling at all. ## What you may notice with it. The wine cellar cooling unit problems HA tends to arrive with.

Keep the cellar door shut and confirm the reading with a separate thermometer. If it comes back, it needs a visit. ### Why did HA not appear until my cellar had been warm for an hour? Wine-Mate delays its temperature alarms by 60 minutes by default and holds them off for 23 hours after start-up, so a short warm spell after the door is opened does not set them off. ### Can a Wine-Mate call my phone when HA comes on? Units fitted with the alarm call option send a spoken notice when the cellar passes the high or low limit. Wine-Mate suggests testing it by setting both alarm delays to zero, then restoring 60 minutes and 23 hours. ### Does HA mean my Wine-Mate is low on refrigerant? Not necessarily. Wine-Mate's own chart lists poor insulation, a restricted exhaust, a dirty condenser and fan problems alongside leaks, and those are quicker to rule out before gauges go on. --- **[Read on the site: Wine-Mate HA: the cellar is warmer than its alarm limit](https://winecellarrepair.center/error-codes/wine-mate-ha/)** **[Book a visit with WineCellarRepair.center](https://winecellarrepair.center/schedule/)**
