Bosch Side-by-Side Refrigerator: What to Know Before Buying One Used

A used Bosch side by side refrigerator lists for about $1,400 to $1,625 on our marketplace right now, and the one you are most likely to find is the 300 Series B20CS30SNS, a 36 inch counter-depth unit with 20.2 cubic feet inside. New, that same model has been listed around $1,940 at online retailers, and it was back-ordered when I checked. That is a thin discount for a used machine. So the whole question with a used Bosch is not "is it cheap enough." It is "is this one good enough to pay nearly new money for."

I help people buy and sell large appliances for a living, and Bosch refrigerators behave differently from the Whirlpool and GE units that make up most of the used market. They hold their price, they are built for a flush kitchen look, and they have a short list of parts that fail. Below is what I check on a used Bosch side-by-side, whether it will actually fit your opening, what repairs cost, what to pay, and how to get it home without wrecking it.

Is a Bosch Side by Side Refrigerator Reliable Enough to Buy Used?

Yes, if it is under about eight years old and passes a ten minute running test. Bosch sits in the middle of the pack on reliability, and the failures it does have are known and fixable.

That matters more than any brand ranking. A used refrigerator is a good buy when its weak points are predictable, because then you know exactly what to test. On a Bosch side-by-side, the list is short: the evaporator fan, the ice maker, and the electronic control board. Service companies like Sears Home Services list the same handful of symptoms over and over, a warm fresh food side with a cold freezer, a buzzing noise from the back of the freezer, and an ice maker that stops harvesting.

The sealed system itself is conventional. The rating plate on a B20CS30SNS lists R134a refrigerant, a 115 volt supply on a 15 amp circuit, and a 2.2 amp defrost heater. Nothing exotic, which means any qualified appliance tech can work on it. Bosch is made by BSH Home Appliances, the same group behind Thermador, so parts come through a real U.S. supply chain rather than a one-off importer.

My take: a Bosch side-by-side is not a refrigerator I would buy at twelve years old. It is one I would happily buy at three to six, because that is where it still has most of its life left and the seller has already eaten the first hit of depreciation.

Counter Depth vs Standard Depth: Will a Used Bosch Fit Your Kitchen?

Most used Bosch side-by-sides are counter-depth, so they are shallower and smaller inside than the standard-depth fridge you may be replacing. Measure before you fall in love with one.

The B20CS30SNS is 35 15/16 inches wide, about 69 3/4 inches tall, and 27 1/2 inches deep with the doors on. Take the doors off and the cabinet depth drops to 25 15/16 inches. That is the whole point of counter depth. The box sits nearly flush with a standard 24 to 25 inch countertop, so the kitchen looks built-in without paying built-in prices.

The tradeoff is space. Inside you get 13.2 cubic feet of fresh food and just under 7 cubic feet of freezer, 20.2 total. A typical standard-depth side-by-side runs in the mid 20s. If you are a family that shops for the week, you will feel that difference on the first Sunday.

Measure three things before you commit:

• Opening width. You need at least 36 inches. Leave a little extra on the hinge side so the doors swing past 90 degrees and the crisper drawers can slide out.
• Opening height. Allow an inch above the roughly 69 3/4 inch cabinet height for air and for tilting it into place.
• Every doorway on the route in. At 27 1/2 inches deep with doors, plus the handles, it squeezes through a standard 30 inch interior door. A 28 inch door means the refrigerator doors come off first.

One more thing the rating plate tells you: "Free standing installation only." This is not a panel-ready built-in. If you want a Bosch that disappears into cabinetry, that is the Benchmark line, a different machine at a very different price.

What a Used Bosch Side by Side Refrigerator Costs

Expect to pay $1,400 to $1,625 for a clean, working used Bosch side-by-side, against roughly $1,940 for the same model new.

Those are real asking prices from our marketplace in October 2026. Bosch refrigerators across every configuration list between about $1,400 and $2,025, with French door units at the top. For context, the median used side-by-side from any brand sits near $1,480, so a Bosch is priced right at the market, not at a premium.

Option	Typical price	What you get
Used Bosch side-by-side (300 Series)	$1,400 to $1,625	36 inch counter depth, 20.2 cu ft, ice and water through the door
New Bosch B20CS30SNS	About $1,940	Same unit, full factory warranty, often back-ordered
Used side-by-side, any brand	About $1,480 median	Mostly standard depth, more interior space
Used Bosch French door	Up to about $2,025	Wider shelves, bottom freezer drawer

The saving on a used Bosch is a few hundred dollars, not a thousand. That is the case for buying used only if the unit is young, clean, and fully tested. A seven year old Bosch with a weak ice maker is not worth $1,500 when a new one is $1,940. Our used refrigerator price index tracks these midpoints month to month if you want to check a listing against the current market.

How to Inspect a Used Bosch Refrigerator Before You Pay

Plug it in, let it run, and test the three Bosch weak points in order: the evaporator fan, the ice maker, and the controls. Then do the checks every used fridge needs.

1. Listen at the back of the freezer. A soft whir is the evaporator fan doing its job. Buzzing, grinding, or ticking means the fan motor is going, and a failing fan is the most common reason a Bosch fresh food side runs warm while the freezer stays cold.
2. Compare the two sides with thermometers. After an hour you want 37 to 40 degrees in fresh food and about 0 in the freezer. If the freezer is fine and the fresh food side is drifting into the high 40s, suspect the fan before anything else.
3. Make the seller run the ice maker the day before. You want a full bin of solid cubes. Empty or half-formed cubes point at the ice maker assembly or the water valve.
4. Press every button on the dispenser panel. The display, lock, ice and water selections should all respond. A dead or flickering panel is a control board question, and boards are the most expensive common part.
5. Check the door gaskets. Close a dollar bill in the door at a few points and pull. No drag means the seal is worn. Gaskets are cheap. Years of a bad seal are not, because the compressor has been working overtime.
6. Look for water under the crisper drawers. Ice or standing water down there means a blocked defrost drain or a defrost problem.
7. Photograph the rating plate. It sits on the inside wall of the fresh food section. You need the full model and the FD number to order parts and to look up the build date.

Smell it too. A refrigerator that sat unplugged with food inside holds that odor in the liner, and no amount of baking soda fixes it. That is a walk-away, whatever the price.

What Bosch Repairs Cost if Something Fails

Most Bosch side-by-side repairs land between $200 and $450 with labor. The exceptions are the control board and anything in the sealed system.

These are ballpark numbers for a used buyer deciding what risk to price in, not quotes. A service call alone typically runs $100 to $200 before parts.

• Evaporator fan motor: roughly $200 to $350 installed. The most likely repair on a Bosch, and a reasonable one.
• Ice maker assembly: roughly $250 to $450 installed. Annoying, not fatal. Some owners just switch the ice maker off and live without it.
• Door gasket: $50 to $150 for the part, and a patient owner can fit it themselves.
• Main control board: often $400 or more installed. This is the one that changes the math on an older unit.
• Compressor or refrigerant leak: not worth repairing on a used unit at these prices. Walk away.

Bosch's own customer service number is printed right on the rating plate, 800-944-2904, and it is the fastest way to confirm whether a specific serial is still under any warranty coverage before you buy.

Moving a Used Bosch Side by Side Without Damaging It

Keep it upright, protect the doors and the floor, and let it stand before you plug it in. Most damage to a used fridge happens on the trip, not in the kitchen.

A counter-depth side-by-side weighs several hundred pounds, and it is top-heavy once the doors swing. Tape the doors shut. Wrap the stainless in moving blankets, because a dented door panel on a Bosch kills a big chunk of resale value. Use an appliance dolly with a strap, never a furniture dolly with no restraint, and lay a runner down so the leveling legs do not gouge hardwood.

If it has to go on its side, lay it on the hinge side, not the front or back. Then stand it up and wait before plugging it in. A few hours is fine if it stayed upright. Give it a full 24 hours if it was laid down for any length of time or you do not know. Oil in the compressor needs to settle back where it belongs.

Disconnecting the water line is the step most people rush. Shut the supply valve first, then pull the line, and have a towel ready. A dripping line inside a box truck is how a refrigerator arrives with water in its base.

Should You Buy a Used Bosch or Something Else?

Buy a used Bosch side-by-side if you want a counter-depth look and the unit is young. Buy something else if you need maximum space or the cheapest working fridge.

1. You want flush, built-in looks without built-in prices: a used Bosch 300 Series is one of the best ways to get there.
2. You need the most storage for the money: a standard-depth side-by-side from Whirlpool or GE. See our guide on buying a used Whirlpool refrigerator.
3. You want a true built-in that lasts twenty years: that is Sub-Zero territory. Here is what to check on a used Sub-Zero.
4. You are comparing configurations, not brands: start with our used side by side refrigerator guide.
5. The Bosch is over eight years old and priced over $1,300: pass. The math only works on young units.

Bosch Side by Side Refrigerator FAQ

How long do Bosch refrigerators last?

Plan on 10 to 15 years with normal care. That is in line with most modern refrigerators. The parts that fail early, the evaporator fan and the ice maker, are replaceable, so a well-kept Bosch can reach the top of that range.

Is a Bosch side by side counter depth?

The common ones are. The 300, 500 and 800 Series side-by-sides, model numbers starting with B20CS, are 36 inch counter-depth units, and the 300 Series measures about 27 1/2 inches deep with the doors on. Check the exact model on the rating plate before you measure.

Where is the model number on a Bosch refrigerator?

Inside the fresh food compartment, on a white rating plate on the side wall. It lists the model, an FD number that identifies the production run, voltage, and refrigerant type. Photograph it before you buy.

Why is my used Bosch freezer cold but the fridge warm?

Almost always the evaporator fan. It moves cold air from the freezer coil into the fresh food side, and when it slows or stops, the freezer stays cold while the fridge warms up. It is a common, fixable repair.

Is it cheaper to buy a used Bosch or a new one?

Used, but not by much. Expect to save a few hundred dollars. That makes condition, age, and a real running test more important than the price tag.

Buying a used Bosch privately means inspecting a several hundred pound machine in a stranger's kitchen and hoping it survives the drive. We take that off your plate. Every refrigerator is inspected before it moves, our drivers bring it in and set it up, and you get time in your own kitchen to confirm it runs before you pay, with a 60 day warranty behind it. Read how it works, then browse used refrigerators near you.
