What size is the Ikea built in microwave cabinet?
For the Ikea IBMS1450YB0 built-in microwave, the cabinet opening is determined by the specific cabinet system and the microwave cutout requirements. A common Ikea solution is a Sektion high cabinet designed for a microwave, which is typically 24 or 30 inches wide, about 24.75 inches deep, and 80 or 90 inches tall overall (cabinet size, not the microwave cutout).
What to measure before you buy or install
Measure the cabinet and opening so the microwave can slide in with proper clearance and ventilation.
- Cabinet inside opening width at the front and back
- Opening height (top to bottom of the microwave space)
- Opening depth to the back panel (and any outlet box)
- Face frame or door clearance so the door opens fully
- Ventilation gaps required above, below, or behind the unit
Typical cabinet sizes vs. what matters for fit
Cabinet “overall size” and “microwave cutout” are different. Use this as a quick reference.
| What you’re checking | Typical value for Sektion microwave high cabinet | Why it matters |
|---|---|---|
| Cabinet width | 24 in or 30 in | Must match your kitchen layout |
| Cabinet depth | ~24.75 in | Ensures the unit does not hit the back wall/outlet |
| Cabinet height | 80 in or 90 in | Affects where the microwave sits ergonomically |
| Microwave cutout | Varies by model | Determines whether IBMS1450YB0 physically fits |
If the microwave does not fit the opening
If the opening is too tight or the unit sits proud of the cabinet, these are the most common causes:
- Cabinet opening is sized for a different microwave series
- Outlet or junction box is positioned where the chassis needs to sit
- Trim kit or mounting hardware is missing or incorrect
- Cabinet rails/supports are installed at the wrong height
Why it matters
Correct cabinet sizing prevents door interference, overheating from restricted airflow, and installation stress on the chassis. It also helps avoid cosmetic gaps around the trim.
If you are troubleshooting a door that will not close after installation, check the door alignment and interlock area; the switch W10211972 is one of the key door-safety components used on this model.

What is the thing inside the microwave called?
Inside your Ikea built-in microwave model IBMS1450YB0, the most commonly referenced “thing” is the turntable system (the glass tray and the motor that spins it). People also use the phrase to mean the magnetron system that creates microwave energy, plus safety and power components that support heating.
Common “things inside” a microwave (and what they do)
- Turntable tray: the glass plate your food sits on
- Turntable motor: spins the tray for more even heating
- Door interlock switches: confirm the door is closed so the unit can run
- Fuse and fuse holder: protect the microwave if there is a power surge or short
- Inverter or transformer: supplies high voltage to the heating system
Parts you can replace on IBMS1450YB0
If you are trying to name a part because something is broken, these are common service parts for this model:
| What you see/notice | Likely part name | Example part for this model |
|---|---|---|
| Tray not turning | Turntable motor or tray | Microwave turntable motor W10911403, microwave turntable tray W11373838 |
| Microwave dead, no display | Fuse or fuse holder | Fuse (black) WP4375321, fuse block W10245194 |
| Runs only with door held a certain way | Door interlock switch | Switch W10211972 |
Why it matters
Using the right name helps you match the correct replacement part and troubleshoot faster. For example, “tray” issues usually point to the turntable motor or tray, while “won’t start” issues often involve the door interlock switch or a blown fuse.
Quick safety note before checking internal parts
- Unplug the microwave before any inspection
- Do not remove the outer cover unless you are trained (high-voltage components can store energy)
- If you smell burning or see arcing, stop using the microwave until it is repaired

Can an Ikea microwave cover go in the dishwasher?
Most Ikea microwave splatter covers are dishwasher-safe, and you can typically wash them on the top rack using a normal cycle. For the Ikea built-in microwave model IBMS1450YB0, the cover is an accessory (not a built-in microwave part), so confirm the care marking on the cover itself before washing.
Quick dishwasher guidelines (what we recommend)
- Put the cover on the top rack to reduce heat exposure.
- Use mild detergent; avoid harsh, high-alkaline cleaners.
- Skip heated dry if the plastic feels lightweight or flexible.
- Keep it away from the heating element and high-heat zones.
- Rinse off greasy splatter first so it does not redeposit.
How to confirm in 30 seconds
Look for one of these on the cover:
- “Dishwasher safe” text
- A dishwasher icon
- “Top rack only” marking
If there is no marking, hand-wash with warm water and dish soap to prevent warping or clouding.
What’s safe to dishwash vs. what’s not (typical)
| Item | Usually dishwasher-safe? | Best practice |
|---|---|---|
| Plastic splatter cover | Yes | Top rack; skip heated dry if unsure |
| Metal rack (if included) | No | Hand-wash and dry |
| Charcoal/grease filter | No | Replace or clean per type |
Why it matters
High dishwasher heat and aggressive detergents can warp some plastics, which can make a cover sit unevenly and trap steam or splatter. Keeping the cover flat and clear helps your microwave heat more evenly and keeps cleanup easier.
If you are troubleshooting door or safety issues on IBMS1450YB0 (unrelated to the cover), the door interlock system is a common area to inspect; see the switch W10211972.

Can Ikea porcelain go in the microwave?
Yes, most Ikea porcelain dinnerware is microwave-safe, so it can be used in your Ikea built-in microwave model IBMS1450YB0 as long as the piece is labeled microwave-safe and has no metallic trim or cracks.
Quick safety checks before you heat it
- Look for a “microwave-safe” marking on the bottom of the dish.
- Avoid any gold, silver, or metallic paint/trim (it can arc and damage the dish and microwave).
- Do not use porcelain that is chipped, cracked, or crazed (fine surface cracking).
- Heat in short intervals at first; stop if you see sparking or smell burning.
- Use a microwave-safe plate under the dish if you are unsure and want an extra barrier.
Best way to test a questionable piece (1-minute water test)
- Put the empty porcelain dish in the microwave.
- Place a microwave-safe cup with water next to it.
- Heat for 60 seconds.
Result guide:
| What happens | What it means | What to do |
|---|---|---|
| Dish stays cool, water gets hot | Dish is likely microwave-safe | Normal use is OK |
| Dish gets hot, water is warm | Dish absorbs microwave energy | Use lower power or avoid |
| Sparking/arcing | Metallic content or defect | Stop immediately; do not use |
Why it matters
Using non-microwave-safe porcelain can cause arcing, overheating, or breakage. That can also stress door safety systems and internal electrical components in a built-in microwave.
If your microwave ever stops running after a sparking event, a common protection part to check is the fuse (black) WP4375321.
