Bosch B21CL80SNS/02 bottom-mount refrigerator Parts

No. Bosch refrigerator height varies by model and style; they are not all 72 inches tall. For the Bosch B21CL80SNS bottom-mount refrigerator, the installation dimensions show an overall height of about 69 7/8 inches, not 72 inches (allow extra clearance for ventilation and leveling). See the installation guide for the exact dimension diagram.

What this means for Bosch B21CL80SNS

Your B21CL80SNS is designed to fit many standard kitchen cutouts without requiring a 72-inch-tall opening.

• Listed overall height: 69 7/8 in (1775 mm)
• Recommended clearance: 1/2 in at the top and 2 in behind for ventilation
• If installing next to a wall: allow 3 3/4 in minimum on the wall side for door swing

Quick height comparison (common refrigerator categories)

Heights vary widely across Bosch and other brands depending on configuration.

Refrigerator type	Typical height range	Notes
Bottom-mount (like B21CL80SNS)	68 to 71 in	Often under 72 in to fit standard cabinetry
French door	68 to 71 in	Many are close to 70 in
Side-by-side	65 to 71 in	Some are shorter; depends on capacity
Built-in	80+ in	Requires a tall built-in cutout

How to measure correctly before you buy or install

Use a tape measure and confirm both the appliance height and the space opening.

• Measure floor-to-cabinet height in multiple spots (floors can slope)
• Include clearance for hinges and airflow (top and rear gaps)
• Confirm the refrigerator can be leveled without hitting the cabinet above
• Check door swing clearance if the unit sits next to a wall
• Plan for moving the unit in (doorways and tight turns)

Why it matters

A 2-inch difference in height can prevent proper ventilation, make leveling impossible, or cause the cabinet above to rub the door. Using the model-specific dimensions for B21CL80SNS helps avoid fit problems and protects cooling performance.

On your Bosch B21CL80SNS bottom-mount refrigerator, the most reliable “reset” for the ice maker is to switch the ice maker off and back on using the Ice Maker button, then allow time for the freezer to reach set temperature and for the ice maker to cycle. See the B21CL80SNS owner's manual for the exact button sequence and operating notes.

Quick reset steps (what we recommend)

• Confirm the ice storage box is installed and locked in position.
• Press the Ice Maker button to switch the ice maker off (the Ice Maker symbol disappears).
• Wait 30 seconds.
• Press the Ice Maker button to switch it on (the Ice Maker symbol appears).
• Keep the freezer at 0°F (-18°C) and avoid frequent drawer openings while it restarts.
• If it was off for a long time, remove and rinse the ice cube box with warm water (below 140°F/60°C), then air-dry completely before reinstalling.

If it still will not make ice

These checks solve most “no ice” complaints after a reset:

• Make sure the refrigerator is connected to the water supply and the shutoff valve is fully open.
• Check the water line for kinks or pinches.
• Verify water pressure is adequate (low pressure prevents filling).
• Re-seat the ice storage box; if it is not inserted correctly, ice production can stop.
• Level the refrigerator; if it is not level, water can spill from the ice maker and cubes can form irregularly (use the leveling feet).

What to expect after resetting

Situation	What’s normal	What to do
First start or restart	Ice maker begins once the unit reaches set temp	Give it time to cool fully
After turning on	Motor/valve sound may occur after about 2 hours	Normal operation
First batch	Discard first 30 to 40 cubes for hygiene	Then use normally

Why it matters

A proper off/on reset clears many “stuck cycle” issues without replacing parts, and correct leveling plus steady freezer temperature helps prevent leaks, clumping, and slow ice production.

For replacement parts related to ice production (controls, modules, or ice maker components), order from the parts list for this model or search by model number on Sears PartsDirect.

On a Bosch B21CL80SNS refrigerator, an E2 message is an error indication from the control system. In many Bosch refrigerator cases, E2 is tied to an ice maker or temperature-sensing related fault; start by checking ice maker operation, temperatures, and power cycling the unit per the B21CL80SNS owner's manual.

What to do first (quick checks)

• Power reset: Unplug the refrigerator (or switch off the breaker) for 2 to 5 minutes, then restore power.
• Confirm temps: Set the freezer to 0 °F (-18 °C) and the fresh food section to 41 °F (5 °C) (Auto Mode targets).
• Check ice maker basics: Make sure the ice bin is seated correctly and the ice maker is turned on.
• Verify water supply: Confirm the shutoff valve is fully open and the supply line is not kinked.
• Look for related symptoms: No ice production, intermittent cooling, or a non-responsive display can help narrow the cause.

Common causes and the parts that typically relate

E2 can show up when the refrigerator detects a problem it cannot correct automatically. These are common areas to inspect on this model:

Symptom you notice	Most likely area	Example part on this model page
Ice maker stopped making ice	Ice maker module or drive	Refrigerator ice maker 11016457
Display acts odd or won’t respond	User interface/display	Refrigerator display module 12013739
Cooling seems inconsistent	Main control or power electronics	Refrigerator electronic control board 11016442
Water-related ice issues	Water valve or tubing restriction	Valve-two way 12013732 or refrigerator water tubing 00646836

Why it matters

When E2 appears, the refrigerator is telling you it is seeing a condition that can affect ice production, temperature stability, or control operation. Addressing the underlying cause quickly helps prevent food temperature swings and repeat error codes.

When replacement is the right next step

Replace a part when the symptom is consistent and repeats after a reset:

• Ice maker never cycles or never fills after water supply checks: consider refrigerator ice maker 11016457.
• Display issues persist (blank, stuck segments, buttons not responding): consider refrigerator display module 12013739.
• Multiple functions act erratically (temps, fans, ice maker) with recurring errors: consider refrigerator electronic control board 11016442.

The most common problem we see with Bosch fridge freezers, including model B21CL80SNS, is a cooling complaint: food too warm or too cold. It is usually caused by doors or drawers not sealing, airflow restrictions, or a control or fan issue; use the owner's manual troubleshooting chart to narrow the cause.

Most common symptoms and what they point to

• Food too warm: door not closing, drawers out of position, or door seals not sealing
• Food too cold: temperature set too low
• No display, no lights, not running: power supply issue (cord, breaker, outlet)
• Ice maker issues: water supply kinked/shut off, low water pressure, or ice box not seated
• Freezer performance drops: drawers left open (can lead to heavy ice and higher energy use)

Quick checks we recommend first

• Confirm doors and freezer drawers close fully; re-seat bins and drawers so nothing hits the door.
• Clean the door seals and the sealing surface; residue can prevent a tight seal.
• Verify temperature settings; raise the setting if items are freezing in the refrigerator section.
• Check power at the outlet and the breaker; a loose plug can mimic a failure.
• For ice maker complaints, confirm the shutoff valve is open and the line is not kinked.

Common causes vs. what to do next

What you notice	Most likely cause	What to do next
Fresh food is warm	Door not sealing or closing	Level unit, reposition drawers, clean/adjust seals
Fresh food is freezing	Temperature set too low	Adjust to a warmer setting
Unit appears dead	No power	Plug in, reset breaker, confirm outlet power
Poor airflow/noisy	Fan or airflow restriction	Clear vents; inspect fan operation

When a part is the likely fix

If basic checks do not resolve it, common repair-direction parts for this model include the refrigerator electronic control board 11016442 and the Bosch refrigerator evaporator fan motor 12014139.

Why it matters

Small sealing or airflow problems quickly turn into temperature swings, frost, and higher energy use; correcting the root cause early helps protect food and prevents repeat issues.
