I have turned it off and hope that this melts..Why is this happening? This is the second time I noticed that this has happened. this was not cheap unit. It was a custom mpdel.

The Thermistor has failed or is failing. It is the temperature sensor that is basically your electronic thermostat.
Troubleshooting Guide: U-Line Refrigerator Error Codes U-Line refrigerator troubleshooting begins with cracking the codes. Let's take a look at U-Line brand error codes.

Error Code ER

Diagnosis: Thermistor 1 is open

Explanation: The U-Line refrigerator error code ER is alerting you to a failed thermistor. Thermistors are used for various temperature readings. These provide reliable temperature readings using a resistance which varies based on surrounding temperatures. If you have a U-Line wine cooler, for example, it will include ambient temperature surrounding the refrigerator unit.
If the thermistor 1 fails, the refrigerator will continue to operate on a preset 10 minutes on and 30 minutes off time interval.

Solution: Use an accurate ohm meter to test the thermistor. If the thermistor is defective, have it replaced.

They are usually an expanding plug. You push it to the hole and press the central pin. If you can grip it with pliers, you can pull it out. The other way is to use a nail punch and push the pin all the way through, pull out the support and retrieve the pin from the insulated cavity.

Most cases of ice build up can be traced to seals that leak humid air into the cooler. Check the door seal carefully using a fresh $1 bill. The bill should not pull out easily when the door is closed. If the unit has a self defrost feature it it is not coming on. Ice buildup inside a wine cooler is very rare. The cooler box should not reach 32deg in normal operation. Does the unit seem to run continuously?
