Please helpHell, I have a TSSU-48-18M-B sandwich prep table and has the following issue please help. Noticed it not working so it was ready 20 deg c I unplugged it and plugged it back in and the compressor kicked In and the fans went on and the temp dropped down to 2 deg then up to 4 deg then back to 2 then it goes up to 20 deg and then blows warm air??? Every time I unplug it then plug it back in it seems to do the exact thing??? I’ve checked to make sure the coil is clean (not perfect) Please help??
