Fisher & Paykel Not Cooling Evenly? The ActiveSmart Fan Motor Is a Common Culprit
What I Found On This Fisher & Paykel Service Call
I drove up the hill into Laguna Beach late in the afternoon to look at an integrated panel-ready Fisher & Paykel RS column. The owner had the column flanked by a matching freezer column — a beautiful side-by-side built into the cabinetry, all flush with the kitchen panels. Her complaint was specific: the top two shelves were warm, the bottom drawers were fine, and the digital control kept showing the setpoint at 37 but the actual temp at the top was reading closer to 50.
A fridge that won’t cool evenly top-to-bottom is almost always an airflow problem, not a refrigerant problem. The Fisher & Paykel ActiveSmart system uses a small evaporator fan inside the cabinet to push cooled air up and around the compartment. When that fan slows down or stops, the cold air pools at the bottom and the top shelves never get the circulation they need. From the outside the fridge sounds like it’s working — you hear the compressor, you might even feel cold near the bottom — but the top stays warm.
I started by confirming nothing simple was wrong. Door gasket on the RS column was tight, condenser at the base was clean, the drain wasn’t iced. The defrost cycle on these is electronic and was running fine according to the unit’s service menu. So I pulled the back interior panel inside the fresh-food compartment to get eyes on the ActiveSmart fan motor.
How I Narrowed It Down
The fan was running, but it was running rough. You could hear the bearing whining and feel a slight vibration in the panel. I disconnected the motor and spun the blade by hand. There was grit and resistance in the bearing — not seized, not free, just on the way out. The motor was still spinning enough to fool the unit’s diagnostic into thinking everything was fine, which is why no error code had ever shown up on the display. But it wasn’t moving enough air to keep the top shelves cold.
I should also mention — on the F&P column platform, the panel-ready installation can hide some adjacent problems. If the top venting at the cabinet ceiling is partially blocked, the RS column compressor and condenser overheat, the unit starts compensating, and the symptoms can look a lot like a fan problem. I always look at top vent clearance before condemning a motor. This install had the right venting at the cabinet top, so I was confident the fan was the real fault.
The Fix and What It Took
The ActiveSmart fan motor on the RS column is a Fisher & Paykel-specific part. I had a compatible motor on the truck, pulled the old one, swapped the new one in about thirty-five minutes, and put the back panel back together. Ran the column through a fresh pulldown — top shelf temperature dropped from 50 down into the high 30s within a few hours, exactly where it’s supposed to sit.
Total time on site was around ninety minutes. Customer paid the flat repair price — diagnostic was waived because she moved forward with the repair. Parts and labor carry our 3-month warranty.
A note if you’re trying to diagnose this at home. If your top shelves are warm and your bottom drawers are fine, the most likely explanation is reduced airflow from the evaporator fan. If the whole fridge is warm uniformly and the compressor is running constantly, that’s a different problem — usually a sealed-system or sensor issue, not a fan one.
If you’re in Laguna Beach, Corona del Mar, or anywhere in Orange County and your Fisher & Paykel refrigerator isn’t cooling evenly, give us a call. We’re an independent shop with specialists experienced on the ActiveSmart platform and the RS column, and we can usually get out the same or next day. $65 diagnostic, waived with repair.
