Fix Fisher & Paykel integrated fridge door seal

Fisher & Paykel ActiveSmart integrated fridge freezer (model RS9120W) with a custom timber door panel and a freezer drawer below. The fridge door doesn't appear to be closing and sealing properly, and condensation is building up on the ceiling inside the fridge, which suggests warm air is getting in past the seal. I'm after an appliance technician with Fisher & Paykel integrated fridge experience (not a general handyman) to work out why it isn't sealing (door or panel alignment, hinge, levelling or seal), adjust or fix it on the day where possible, and quote any parts before ordering. The original installation guide is on hand.
