Reviews from Seattle Sub-Zero owners

Came down one morning and the fridge side was at 58 degrees while the freezer was fine. I figured the whole thing was done. The tech found the evaporator fan had failed and one dual-refrigeration circuit wasn't running. Replaced the fan, checked the charge, and it held 38 by that evening. Saved me from buying a new column.

Our undercounter ice maker just stopped making ice — the reservoir was full but nothing was freezing. He diagnosed a failed water inlet valve and a clogged fill tube, both of which he had on the truck. Cleaned the system, swapped the valve, and we had a full bin the next morning. Quick, no upsell, no mess.

Water kept pooling under the freezer drawer and freezing into a sheet at the bottom. Turned out the defrost drain was blocked with ice — a common thing on these, apparently. He flushed the drain line, added a small heater clip to keep it from refreezing, and cleaned up the water. No more puddle two months on.

My 632 is probably 25 years old and started building up frost on the back wall of the freezer, then the fridge slowly warmed. I assumed it was toast. The tech traced it to a bad defrost termination thermostat, replaced it, and manually cleared the ice. Runs like it did years ago. He clearly knew these older units cold.

The freezer stopped holding temperature and I could hear the compressor trying to start and clicking off. I braced for the worst. He confirmed a failed start relay and an overheating compressor, but the sealed system itself was sound. Replaced the relay and overload, added a hard-start kit, and it's been steady since. Honest about what did and didn't need doing.

My integrated wine unit couldn't hold the lower zone below 58, which is no good for the reds I keep long-term. The technician found a failed thermistor and a fan that wasn't pulling air across the second evaporator. Both fixed same visit. Both zones now sit exactly where I set them. He treated the cellar like it mattered.

The door on our integrated column wasn't sealing — you could feel cold air leaking at the bottom corner and it was sweating around the frame. He measured the gap, replaced the worn magnetic gasket with a genuine Sub-Zero one, and adjusted the door alignment. Seals tight now and the condensation is gone. Fair price for the part too.

Ours had developed this loud grinding whir that got worse over a couple weeks — loud enough to hear from the living room. I worried it was the compressor. It was actually the condenser fan motor and a build-up of dust and pet hair on the coil. He replaced the motor, cleaned the condenser, and now it's quiet again.

The undercounter freezer drawers kept icing over — everything inside got coated in frost within days of a defrost. He found the drawer gasket wasn't seating and warm air was getting in, plus a lazy defrost heater. New gasket, new heater, and reset the defrost timing. Been frost-free for weeks now. Showed up when he said he would.

The display on our newer built-in went dark and the whole unit stopped responding — no cooling, no lights, nothing. He isolated it to a failed main control board rather than the compressor, which was a relief. Ordered the genuine board, came back two days later, installed it, and reprogrammed the temps. Working perfectly and he kept me posted the whole time.

Our 685 threw an EC40 code and the freezer crept up to around 15 degrees. I had no idea what the code meant. The tech explained it pointed to a sealed-system issue, ran a full diagnostic, and found a partial restriction rather than a leak. Cleared it, recharged, and verified pulldown over an hour before leaving. Careful, methodical work.

Our older built-in was running nonstop and the kitchen side of it felt hot. The bill crept up too. He pulled the grille and the condenser coil was packed solid with dust — hadn't been cleaned in probably a decade. Deep-cleaned the coil, checked the fan and charge, and the compressor finally started cycling normally again. Simple fix, big difference.
