When the fridge stops holding temperature, food and time are on the line. We diagnose sealed-system, evaporator, gasket and control faults on built-in and freestanding refrigerators across Littleton and the Southwest Denver foothills.
A refrigerator rarely fails all at once. It drifts, sweats, or runs louder before it quits. These are the complaints Littleton homeowners call us about most.
Not cooling or cooling unevenly, warm fresh-food compartment with a still-frozen freezer (or the reverse), frost building on the back wall, water pooling under crisper drawers, and a compressor that runs nonstop without ever reaching temperature. On built-in and dual-evaporator models, one compartment can drift out of range while the other seems fine, which usually points to an evaporator fan, damper, or defrost fault rather than the compressor.
We also handle the quieter failures: door gaskets that no longer seal, condensation and sweating on the cabinet or door mullion, ice makers that stop or overflow, and noisy or clicking sealed systems. Catching these early often means a gasket or fan motor instead of a full sealed-system repair, so it is worth a call before the problem cascades.
Every visit starts with a $89 diagnostic service call, credited toward the repair. Here is the order we work in so we find the real fault, not just the symptom.
We confirm actual fresh-food and freezer temperatures against the setpoint, so we know whether the problem is cooling, airflow, or a control reading the wrong value.
We inspect evaporator fans, dampers, and the defrost cycle. On dual-evaporator models we isolate which compartment is failing before touching the sealed system.
If cooling is genuinely lost, we test the compressor, start components, and look for sealed-system symptoms like a warm condenser or a system that pulls down slowly.
We check door seals, control boards and thermistors, and drain lines, since a bad gasket or blocked drain can mimic a cooling failure.
You get a clear repair estimate before any parts go in. Refrigerator repairs start from $149, with the final price set only after the on-site diagnosis.
Built-in and integrated refrigerators from the high-end brands are not just larger versions of a basic fridge. Many run dual evaporators so the fresh-food and freezer compartments cool independently, with separate airflow, dampers, and sometimes separate defrost cycles. A tech who treats every no-cool as a compressor problem will replace the wrong part.
Sealed-system work also demands the right approach: correct evacuation, proper charge, and OEM-quality, factory-specified parts. We diagnose the whole cooling path, from the door gasket that lets warm air in to the control board that governs the compressor, so the fix holds instead of failing again in a month.
Littleton sits at roughly 5,350 feet, and the Front Range air is dry. Both quietly affect refrigerators.
The dry climate wears door gaskets faster than in humid regions. A stiff, cracked, or shrunken gasket lets warm air leak in, forcing the compressor to run longer and creating condensation and frost inside. That is why we inspect the seal on every no-cool and every high-run-time call. Because dry outside air also changes how condensation behaves, a fridge that sweats or drips here can point to a drain or damper issue rather than humidity alone, and we trace it to the real cause rather than guessing.

Dual-evaporator built-ins, column units, and integrated panels, where compartment-specific cooling faults are common.
Premium freestanding and built-in refrigeration, including sealed-system, fan, and control-board diagnostics.
French-door, side-by-side, and bottom-freezer models where ice makers, gaskets, and defrost systems commonly fail.
Quick Answers
A cold freezer with a warm fresh-food section usually means airflow, not the compressor. The most common causes are a failed evaporator fan, a stuck air damper, or a defrost fault blocking cold air from reaching the fresh-food compartment. On dual-evaporator built-ins each side cools separately, so this points to one evaporator system rather than a total sealed-system failure.
Littleton Appliance Repair charges an $89 diagnostic service-call fee that is credited toward the repair. Refrigerator repairs start from $149, with the final price set only after an on-site diagnosis, since sealed-system work and control-board replacements cost more than a gasket or fan motor. Call (720) 903-2603 to book a visit.
Yes. A refrigerator that runs nonstop often has a failing door gasket letting warm air in, a dirty condenser, a defrost problem, or a sealed-system fault. We diagnose all of these on built-in and integrated refrigerators as an independent specialist, then quote the repair before doing the work.
FAQ
Anything else — call any hour, a real person answers.
Usually it is a clogged defrost drain line, which is a fixable problem, not a failing fridge. As melt water backs up it overflows into the fresh-food compartment. We clear the drain and check the defrost heater and drain-heater on models that have one, so it does not refreeze.
We run service visits daily from 8:00 AM to 6:00 PM across Littleton and the Southwest Denver foothills, and our phone is answered 24/7. Call (720) 903-2603 or book through our online scheduling page and we will get you the soonest available window.
Yes, and it is one of the more common fixes we do here. The dry Front Range air shortens gasket life, and a poor seal causes warm spots, condensation, frost, and long compressor run times. We fit OEM-quality, factory-specified gaskets so the door seals correctly again.
Exterior condensation on the cabinet or door mullion can come from a worn gasket, a mullion heater problem, or high in-home humidity around the unit. On built-ins it often traces to the anti-sweat components rather than the room. We identify which it is on-site rather than guessing.

Our built-in Sub-Zero was keeping the freezer fine but the upper fridge zone was sitting around 55. Turned out to be the dual-evaporator setup, exactly what the tech guessed on the phone. Brian had the sealed system diagnosed the first visit, ordered the part, and had us back to normal within the week. He didn't try to sell us a new unit like the last place did.
One of the dual-stack burners on our Wolf range would click and click but never light. He mentioned it's common up here because the burners need to be calibrated for the altitude, which no one had ever told us. Relit perfectly after and he adjusted the others while he was at it.
Fixed our Sub-Zero the same week we called. Fair price, no upsell.
Our dual-zone wine cabinet had drifted so the bottom zone wouldn't hold temp and there was condensation collecting on the glass. They diagnosed it quickly but the part had to come from the manufacturer and took about four days, so we were without it for most of a week. Once it arrived the fix was solid and both zones are holding right where they should. Worth the wait, just be ready for the parts delay on these.
Miele dishwasher wouldn't drain, standing water in the bottom every cycle. Bad drain pump. In and out in about an hour and he cleaned out the filter housing that was part of the problem too.
The door gasket on our 15-year-old Sub-Zero had gotten brittle and it was sweating around the seal. New OEM gasket and it seals like new again. Appreciated that they used the factory part instead of some universal thing.
Thermador wall oven quit heating right before we were hosting. Called in the morning and they got someone out that same afternoon. Bad igniter. He had the part on the truck and we still made our dinner.
Ice maker in our Sub-Zero was making cloudy hollow cubes and barely any of them. He flushed the system, replaced a valve, and now it actually keeps up when we have people over. Nice guy, wore booties in the house without being asked.
Solid work on our Bosch dishwasher, the drain pump had failed. The only thing is the $89 service call fee felt a little steep before I knew they credit it toward the repair. Once I proceeded it came off the bill, so no real complaint, just wish I'd understood that up front.
Our Viking freezer was building up a wall of frost and not defrosting on its own. Turned out to be the defrost heater. Fixed it and explained what was going on so I understood why it happened.
Two burners on our Wolf cooktop wouldn't spark. Tech recalibrated them for the elevation and swapped the igniters. Works better than it has in years honestly.
Warm upper zone on our Sub-Zero, classic apparently. They knew exactly what it was, ordered the evaporator part, and came back to install it a couple days later. Honest and easy to deal with the whole way through.
Not many people around here will even touch a Gaggenau. These guys did, got the control board sorted, and were straight with me about the cost of the part on a unit this expensive.
Miele steam oven throwing an error and shutting off mid-cook. The tech was great and clearly knew the unit, but he ran about 40 minutes behind the window they gave me and I had to shuffle some things around. Fixed it in one visit though and it's been perfect since, so I'd still call them again.
Had them out for our built-in outdoor grill that wasn't lighting evenly. Didn't expect them to do outdoor units but they did and dialed it in for the altitude. Grilling season saved.
Quick, clean, and they answered when I called at 9pm the night before. Dishwasher's draining again.
This was a big one, the sealed system on our Sub-Zero failed and that's a job a lot of shops won't take on. They did it right, used factory-spec parts, and stood behind the work. Given it's a $12k built-in I'm glad I found someone who actually knew these inside and out instead of just replacing the whole fridge.
Wine fridge kept fogging up on the door and the temp was bouncing around. Fixed same visit and no more condensation.
