Hi. Send me to repair a plate of ice cream not frost.mar Bosch because it burned. I didn't turn on the temperature lights. the compressor and the lights were only. The forcer burned and changed it. When I repair the plate, assemble everything and it does the same to me. to the peer they changed a triac that was seen to cut a leg. Maybe the platelet didn't look good ?????. another thing what I need to activate all the buttons. One that says. Freezing frast. will that???? or I have to take the platelet to check again. The refrigerator is in the client's house and before returning I ask this question. The refrigerator is BOSCH KDN 43
