WINEMATE TROUBLESHOOTING: SELF CONTAINTED UNIT: ONE YEAR WARRANTY ON PARTS AND LABOR
The cooling systems can cool a maximum of 25 degrees below the ambient temperature in the room.
Therefore, you want to place the unit in a room with an ambient temperature in the range of 55° and 78°F.
Models using a more powerful cooling unit (like the 500E) may be suitable for use in areas with an ambient temperature up to 95°F.
****DURING THE HOTTER SUMMER MONTHS:
Units being programmed to 55*f and running continually between 61*f - 63*f, unit is working to best of its ability due to excessive heat
However, if ambient temperature is high as 85*f - 95*f, temperature setting will need to be adjusted higher to prevent continuous operation and potential mechanical damage to compressor motor.
The rated capacity is determined under the cellar and ambient

WM-3500/8500HZD: FRONT AIR SUPPLY 
UNIT NOT COOLING: STAYING AT ROOM TEMP OR HIGHER
The “HA” alarm code would just simply indicate that the unit is registering 10*f above the set temp.
This alarm would sound off due to a variety of factors, yet it is advisable to check for heavy dust or lint accumulation, and to ensure the exhaust fans are fully operational.
If there are signs of excessive sweating, condensate, or heavy ice buildup, then it may be an issue with the exhaust and intake being blocked. If ok, might be a compressor issue or refrigerant issue and would need local service.

UNIT RUNNING TOO COLD BELOW 50*F :
What do you have the unit set to?...Should be set between anywhere from 50*F-65*F.
Can you please tell us if the unit's led display panel is reading/displaying the correct temperature?
If set anywhere between 50-65*f yet running too cold into low 40’s/ mid 30’s,
and panel reads temperature correctly:
BAD TEMPERATURE/DIGITAL CONTROLLER
UNIT DISPLAYS HIGH INCORRECT TEMP:
Should unit run nonstop when set anywhere between 50*f-65*F yet panel reads
a high, false temperature of 80*f/90*f, and temperature too cold: BAD TEMPERATURE SENSOR
UNIT COOLING OK AT STARTUP BUT STOPS COOLING AND OVERHEATS. FANS STOP AND GO:
If you find no hot air blowing out the back nor cold air blowing out from the front corner,
but you feel or hear the compressor itself running, could be an issue with thermostat controller.
If it the compressor itself was shorted, the breaker would trip immediately and unit not be able to run at all to do any sort of cooling.
Next time you hear the unit stopping short with no airflow and minimal vibration, with the palm of hand, try tapping the led screen. Should you hear the fans going again with actual airflow moving, then likely its a digital controller issue.
A replacement controller can be replaced and purchased for $189 including shipping.
UNIT NOT COOLING ENOUGH:
It seems as though its partially cooling, this could be due an airflow issue with the fan motor
If for any reason the condenser fan motor fails, it would overall inhibit cooling.
If the unit’s bottom exhaust vent seems to get excessively hot (and just radiate heat with no actual air flow) to the point where your cabinetry is radiating the heat buildup, the overheating can be due to a non-functional condenser fan motor and a dirty condenser coil.
If the condenser fan motor is not running at all and the condenser coil has dust/lint accumulation, the coil will not have cool, flowing air and the coil will not be able to reject and dissipate the heat.
