Are all range hood microwaves the same size?
No. Over-the-range (range hood) microwaves are often similar in width, but they are not all the same size. For Kenmore model 79080342310, the installation requirements call for a 30-inch-wide cabinet opening and a mounting height of 30 inches minimum above the cooking surface; use the installation guide to confirm your exact clearances before buying or installing.
What’s “standard” for over-the-range microwaves
Most over-the-range microwaves are designed to fit a 30-inch cabinet space, but height and depth vary by model and by venting setup (recirculating vs. outside vent).
Common size expectations:
- Width: typically about 30 inches
- Height: often around 16 to 18 inches
- Depth: commonly 15 to 18 inches (door closed)
Model 79080342310 fit requirements we use for planning
From the installation requirements for this Kenmore microwave/hood combo:
- Space between cabinets: 30 inches wide and unobstructed
- Bottom of cabinet to cooking surface: 30 inches minimum
- Floor to top of microwave: 66 inches minimum
- Intended to be used above ranges up to 36 inches wide
Quick fit check before you replace a microwave/hood combo
Use this checklist to avoid a mismatch:
- Measure the cabinet opening width (inside-to-inside)
- Measure clearance above the cooktop (to the cabinet bottom)
- Confirm whether you need outside venting or recirculating
- Check for power cord clearance in the upper cabinet
- Locate at least one wall stud for the mounting plate
Why it matters
Even when two units are both “30-inch over-the-range,” differences in height, depth, mounting plate position, and duct alignment can turn a swap into a cabinet or vent modification project.
Typical “same size” vs “same fit” comparison
| What you’re matching | Why it can differ | What to verify |
|---|---|---|
| Width | Usually standardized | 30-inch cabinet opening |
| Height | Varies by model | Cabinet-to-cooktop clearance |
| Depth | Door and handle vary | Door swing and backsplash clearance |
| Venting | Duct locations differ | Top/rear exhaust alignment |

What is the code for a microwave above a stove?
For the Kenmore 79080342310 microwave/hood combo, the installation requirements call for at least 30 inches of clearance from the cooking surface to the bottom of the microwave, and 66 inches or more from the floor to the top of the microwave. Electrical supply is 120V, 60 Hz, 15A, on a separate 15 to 20 amp grounded branch circuit; see the installation guide.
Key installation requirements (what to follow)
- Minimum clearance above cooktop: 30 in (76.2 cm)
- Recommended height reference: 66 in (167.6 cm) or more from floor to top of microwave
- Cabinet opening width: 30 in (76.2 cm) wide, unobstructed
- Electrical rating: 120V AC, 60 Hz, 15A (1.6 kW)
- Circuit/outlet: separate 15 to 20 amp grounded outlet in the cabinet above the unit
Electrical and placement details that matter
These requirements are part of what most people mean by “code” for an over-the-range microwave: safe clearances, correct circuit sizing, and proper outlet placement.
| Item | What to use for 79080342310 | Why it matters |
|---|---|---|
| Clearance above cooking surface | 30 in minimum | Reduces heat exposure and improves safe use |
| Circuit | Dedicated 15 to 20 amp branch circuit | Prevents nuisance trips and overheating |
| Outlet location | In cabinet above microwave | Keeps cord protected and reachable |
| Range width compatibility | Up to 36 in wide ranges | Ensures proper coverage and fit |
Why it matters
Over-the-range microwaves combine cooking and ventilation. Following the specified clearance and electrical requirements helps prevent overheating, reduces the chance of tripped breakers, and ensures the vent hood and mounting system work as designed.

What is the life expectancy of a Kenmore microwave?
A Kenmore microwave typically lasts 9 years (with a normal range of 7 to 10 years) under average household use. For Kenmore model 79080342310, regular cleaning, proper ventilation, and avoiding misuse (like running it empty) are the biggest factors that keep key components working longer; see the 79080342310 owner's manual for care guidance.
Typical lifespan and what changes it
Most microwave/hood combos wear out based on heat, door use, and how hard the vent system works.
- Light to moderate use (1 to 5 cycles/day): 9 to 10 years
- Heavy use (many cycles/day): 6 to 8 years
- Poor airflow or heavy grease exposure: shorter life due to heat stress
- Frequent door slamming or misalignment: faster wear on door-latch and switch parts
- Running empty or overheating food splatter: can damage the cavity and internal components
Parts that commonly limit microwave life
When a microwave stops heating, won’t start, or shuts off, these parts are frequent suspects on over-the-range units.
| Symptom | Common area involved | Example part for this model |
|---|---|---|
| Runs but does not heat | High-voltage system | Microwave magnetron 5304519335 |
| Starts then stops, or dead display | Safety/overheat protection | Microwave thermal cut-off 5304509469 |
| Won’t run unless door is held “just right” | Door latch and interlock switches | Microwave door interlock switch 5304509460 |
How to help your 79080342310 reach the full lifespan
These habits reduce heat stress and prevent avoidable failures.
- Keep the interior clean so splatter does not carbonize and cause arcing.
- Use the hood vent fan when cooking on the range to reduce heat and steam rising into the microwave.
- Close the door gently; the latch and interlock system is a safety-critical area.
- Never run the microwave empty; it can overheat internal components.
- If heating performance drops, stop using it and troubleshoot before continued operation.
Why it matters
Microwave/hood combos rely on a door interlock system and high-voltage heating components. Good airflow and careful door use help prevent nuisance shutdowns, no-heat complaints, and premature part wear. If you decide to repair, you can order model-matched replacement parts from the list for 79080342310, or search by model on Sears PartsDirect.
