From warm compartments to iced-over evaporators, we diagnose and repair Bosch French-door, bottom-freezer, and counter-depth refrigerators across Littleton and the SW Denver metro. Independent techs, OEM-quality parts, honest estimates.
Bosch built its reputation on quiet, efficient, counter-depth refrigeration, and that engineering shapes how we approach every repair.
We work on the full Bosch lineup found in Littleton kitchens: the 800 Series and Benchmark French-door and bottom-freezer models (B36CL80SNS, B36CT80SNS, B36FD50SNS), the value-focused 500 Series bottom-freezers, and the 300 Series along with the slim-depth B11CB50SSS built-ins. Most are 36-inch counter-depth units engineered to sit flush with cabinetry, which changes how they vent and how we access the sealed system.
Because Bosch relies heavily on electronic control boards, a linear or inverter compressor, and dual evaporators on many premium models, a symptom like 'not cooling' rarely has a single cause. We read the actual fault codes and test the sealed system rather than guessing, so you are not paying for parts your Bosch does not need.
These are the failure modes we see most often on Bosch units in the Littleton area:
A structured process keeps the $89 diagnostic honest and the repair right the first time.
We enter Bosch service/test mode to pull stored error codes and force the defrost and cooling cycles, which tells us whether the issue is a sensor, a fan, or the sealed system.
We measure fresh-food and freezer temperatures at the evaporator and check the fan, damper, and door gaskets, since a leaking gasket at 5,350 feet in dry air is a frequent culprit.
We check the compressor, inverter board, defrost heater, and thermistors with a meter before condemning any part, so the fix targets the real fault.
You get a firm price before we proceed, the $89 service call is credited toward the repair, and we install OEM-quality parts and re-run the diagnostic to confirm the fix.
Bosch counter-depth and slim-depth refrigerators pack the sealed system, dual evaporators, and control boards into a tight cabinet, so proper reassembly and airflow clearance matter as much as the part itself.
At Littleton's altitude, the dry air is hard on door gaskets and can dry out the defrost drain, so we inspect those on every visit and reseal or clear them before they turn into a warm-fridge callback.
We are an independent repair company, not authorized or certified by Bosch, which means straightforward pricing and no upsell to a warranty program. We install OEM-quality, factory-specified parts for control boards, fans, thermistors, and ice maker assemblies so your Bosch performs the way it was engineered to.
Every estimate starts with the $89 on-site diagnostic and is credited toward the repair. Call (720) 903-2603 any time or book through our online scheduling page.
Quick Answers
On Bosch French-door and bottom-freezer models this usually means the evaporator fan or air damper that moves cold air into the fresh-food compartment has failed, or the defrost system has iced over the evaporator. It is a diagnosable fault, not a lost cause. Call Littleton Appliance Repair at (720) 903-2603 and we will read the fault codes and test the airflow on-site.
We charge an $89 diagnostic service-call fee that is credited toward the repair, and the final price is set after on-site diagnostics. Common Bosch repairs like a defrost heater, evaporator fan, or thermistor start from modest part-plus-labor totals, while control board or compressor work costs more. You get a firm quote before any work begins.
Yes. We service the Bosch 800 Series, Benchmark, 500 Series, and 300 Series refrigerators, including counter-depth French-door, bottom-freezer, and slim built-in models. We use OEM-quality parts and visit homes across Littleton, Ken-Caryl, Columbine, and the SW Denver metro daily from 8 AM to 6 PM.
FAQ
Anything else — call any hour, a real person answers.
Frost on the rear freezer wall almost always points to a defrost fault, a failed defrost heater, a bad defrost thermostat, or a control board skipping the defrost cycle. We test each in service mode and replace only the part that failed.
Usually yes. The most common causes are a stuck or failed water inlet valve, a kinked or frozen supply line, or a worn ice maker module. These are individually replaceable, so you rarely need to swap the whole assembly.
Most repairs are completed in a single visit once we have diagnosed the fault, since we carry common Bosch fans, thermistors, valves, and gaskets. If a control board or compressor part must be ordered, we schedule a prompt return to install it.
It can. The dry air at roughly 5,350 feet dries out door gaskets and defrost drain seals faster than in humid climates, which leads to warm compartments and water pooling under the crispers. We inspect and reseal or clear those on every service visit.

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.
