Build up of ice in wine refrigerator

It might be caused from a broken evaporator.Or from ice being build up on the fan.

temp too cold and door seal not effective are 2 reason for this
48 F is too cold for wines (8.8 C) and continually opening and closing of the door allows humidity into the cabinet that results in frost and ice

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?

normally that means yhe defrost thermstat is bad or the heating element that causes the defrost is bad.

Normal to have a bit of ice. Set the temp to 0 for a few hours every week. Check Seal is good all round the door.

Ice build up wil accor if the evaporater blower goes out and does not crculate the air. If you have the model number off the tag I can be of more assistance, with the mobel number I can break the unit componants down in a diagram

you have a door seal leak, the ice is from outside air getting into the cooler, you might also check for an air leak it the service door in the bottom back of the cooler.

Probably the thermostat is bad , you can bypass it by putting together the two wires from the thermostat and if the unit starts working ,replace the thermostat ;only do this if you havesome knowledge of electrical work and be very carefull.

i would check running temp 1st/possible gas fault
