How much clearance for microwave above stove?
For the Kenmore 66568682891 microwave/hood combo, we install it with 13 1/2 inches minimum clearance from the cooktop to the bottom of the microwave, and 66 inches minimum from the floor to the top of the microwave. See the installation guide for the exact mounting layout.
These measurements help the microwave vent properly, fit the cabinet opening, and stay serviceable.
- 13 1/2 in. minimum from cooktop to bottom of microwave
- 66 in. minimum from floor to top of microwave
- 30 in. minimum cabinet opening width
- 12 to 14 in. recommended upper cabinet depth (helps with removal and servicing)
- At least one wall stud within the cabinet opening for secure mounting
| Measurement | What it means | Target for 66568682891 |
|---|---|---|
| Cooktop to microwave bottom | Heat clearance over the range | 13 1/2 in. minimum |
| Floor to microwave top | Overall mounting height | 66 in. minimum |
| Cabinet opening width | Space between cabinets | 30 in. minimum |
| Upper cabinet depth | Front-to-back cabinet depth | 12 to 14 in. recommended |
Correct clearance protects the microwave/hood combo from excess heat, keeps the exhaust path working as designed (vented or recirculating), and prevents fit issues with the wall bracket, upper cabinet, and ducting.
- Confirm the cooktop surface is level before measuring.
- Measure from the cooking surface, not from burner grates.
- Verify the outlet is grounded and avoid extension cords.
- If your cabinet depth is deeper than 14 inches, plan extra access space for future service.

Is Kenmore a good microwave?
Kenmore microwaves are a good choice for most households because they’re built for dependable everyday cooking and are supported with clear operating and care guidance for the specific unit. For the best experience, match features and maintenance needs to your exact model, such as Kenmore 66568682891 (see the owner's manual).
A microwave/hood combo has to do two jobs well: heat food consistently and vent cooking smoke and odors. For Kenmore units like 66568682891, we focus on these practical measures:
- Heats evenly across common foods (reheat, defrost, beverages)
- Door closes and latches smoothly (door safety lock system)
- Exhaust fan moves air effectively for your cooktop setup
- Lights and filters are easy to maintain
- Common wear parts are replaceable when needed
Use this quick checklist to judge performance and avoid the most common frustrations.
- Heating performance: If it runs but does not heat, the high-voltage circuit is a common area to diagnose (high-voltage components can be dangerous; use a qualified technician).
- Door operation: A worn interlock system can cause no-start or intermittent running.
- Ventilation: Confirm the vent grille is secure and the damper moves freely.
- Filters: Replace charcoal filters on recirculating setups to keep airflow and odor control strong.
- Lighting: Dim or dead cooktop lights are usually a straightforward fix.
| Symptom | Likely area | Example part for this model |
|---|---|---|
| Runs but not heating | High-voltage circuit | Diode W11256462 |
| Won’t start or stops when door moves | Door interlock/switches | Primary switch W10211972 |
| Poor odor control (recirculating) | Charcoal filter | Filter 6800 |
| No cooktop light | Lamp housing/bulb assembly | Lamp assembly 8206232A |
A “good microwave” is usually the one that stays safe, heats reliably, and is easy to maintain. On a microwave/hood combo, ventilation and filter upkeep matter just as much as cooking performance, especially if you cook often on the range below.

How big is a Kenmore microwave model 66568682891 in inches?
For Kenmore microwave/hood combo model 66568682891, the overall exterior size is about 29.75 inches wide, 16.25 inches high, and 16 inches deep. For the exact cabinet cutout and mounting clearances, use the dimensions in the installation guide.
Even when the exterior width is about 30 inches, installation depends on the opening, studs, and clearances.
- Minimum cabinet opening width: 30 inches
- Minimum clearance to cooktop: 13 1/2 inches
- Mounting height reference: 30 inches from cooking surface (or countertop) to the top of the wall mounting bracket
- Support requirement: framing must support up to 150 lb (microwave plus load)
| What you are measuring | Typical value for 66568682891 | Why it matters |
|---|---|---|
| Overall width | 29.75 in | Fits standard 30-in over-the-range space |
| Overall height | 16.25 in | Affects cabinet-to-cooktop clearance |
| Overall depth | 16 in | Impacts how far the unit projects over the range |
| Minimum opening width | 30 in | Confirms cabinet opening compatibility |
Microwave/hood combos are sized to fit standard 30-inch range spaces, but safe installation depends on the required clearances and solid mounting into at least one wall stud. Using the installation specs helps prevent poor vent alignment, door interference, and mounting issues.

What is the life expectancy of a Kenmore microwave?
Most Kenmore microwaves, including the Kenmore 66568682891 microwave/hood combo, typically last 9 to 10 years with normal household use. Keeping the venting and door system in good shape and addressing heating or power issues early helps you get the full expected lifespan.
- Daily run time (heavy use shortens life)
- Heat and grease exposure from cooktop use under the hood
- Door alignment and latching (interlock wear can stop operation)
- Airflow and venting (blocked filters and grilles raise internal temperatures)
- Power quality (frequent surges can stress electronic and high-voltage parts)
- Runs but does not heat food consistently
- Loud humming or buzzing that is new or getting worse
- Stops mid-cycle, goes dead, or trips the breaker
- Turntable stops or runs intermittently
- Door won’t close/latch cleanly or you must push to start
| Symptom | Common area involved | Example part for model 66568682891 |
|---|---|---|
| No heat, but runs | High-voltage circuit | Diode W11256462, capacitor W10850446 |
| Dead/no power after a pop | Safety cutout | Thermal fuse W11707984 |
| Won’t start when door closes | Door interlock system | Primary switch W10211972 |
| Poor venting/odor in recirculating setup | Venting and filtration | Filter 6800 |
A microwave/hood combo like the Kenmore 66568682891 works in a hotter, greasier environment than a countertop unit. Good airflow and a properly working door safety lock system reduce heat stress on components such as the magnetron and thermal protection devices.
- Clean the vent grille and keep airflow paths clear
- Replace the charcoal filter on schedule if you use recirculating venting
- Avoid running the microwave empty; it overheats components
- If heating becomes weak, troubleshoot early using the owner's manual

What are common problems with microwave vents?
Common vent problems on the Kenmore 66568682891 microwave/hood combo are grease buildup on the hood filter, a vent grille that is blocked or damaged, and airflow issues caused by an incorrect venting setup (recirculating vs. top or rear discharge). These issues reduce exhaust performance and can let steam and odors linger.
- Weak airflow or no airflow from the exhaust
- Excess steam coming from the exhaust vent during cooking
- Grease dripping or heavy grease film on the vent grille
- Loud rattling or vibration when the fan runs
- Odors lingering even with the fan on
- Clean the filters regularly; grease should not be allowed to accumulate on the hood or filter.
- Inspect the vent grille for grease blockage, bent louvers, or anything restricting airflow.
- Confirm your venting mode: this model ships ready for ventless (recirculating) operation and can convert to top or rear discharge.
- If you use recirculating mode, replace the charcoal filter on schedule; a saturated charcoal filter is a top cause of poor odor control.
- If the fan sounds normal but airflow is weak, check for a blocked duct (for top or rear discharge setups).
| Symptom | Likely cause | Part that may help (if damaged/worn) |
|---|---|---|
| Odors not clearing in ventless mode | Charcoal filter saturated | Filter 6800 |
| Rattling or poor airflow at the front | Vent grille bent, clogged, or loose | Microwave/hood grille vent 8184599 or microwave/hood grille vent 8184600 |
| Backdraft or outside air coming in | Damper sticking or not sealing | Damper W10843943 |
A microwave/hood combo vent is designed to move steam, smoke, and grease away from your cooktop area. When filters or the vent grille are dirty, airflow drops and grease can build up faster, which makes the fan work harder and the kitchen feel smoky.
- Steam at the exhaust vent during cooking is normal; the microwave is designed to vent steam.
- For safe handling and correct removal of the vent grille and filters, follow the steps in the owner's manual.
