Human Factors
This aircraft had flown through moderate mixed icing between 2000-5000 feet into ZZZ and the pilots landed and elected to put the flaps up without knowing if they still had ice on them. They sat on the ground about 30 minutes waiting for their gate to open. We were the outbound crew for this aircraft and the pilots told us when they deplaned that they had flown through the icing but believed most had melted off on the ground. The temperature was around 28F. When we boarded the plane the APU was running and powering the aircraft for both electricity and air. We started to smell fumes and realized the ground deice people had started to deice without coordinating with us or the outbound crew. The aircraft was not configured for deice and we believe the fumes were from the deice fluid entering the bleed system. We called them and told them to stop the deice until we configured the aircraft for deice.
A320 Captain reported a fume event during preflight a gate due to a communication breakdown between flight crew and ground deicing personnel.
