Just face timed a fellow engineer in the UK and helped him diagnose a E04 fault on a Panasonic VRF. Turns out it was a twin outdoor and the Slave was in a P05, fuse had blown on the power board leading to a missing phase fault. Common issue with a surge but the engineer rarely if ever works on Panasonic. New fuse and a readdress and she kicked in and is running away. #panasonic #panasonicvrf
