Owner’s manual
Can an over the range microwave be used on a countertop?
No. An over-the-range microwave is designed to be mounted to cabinetry and wall structure above a range, not set on a countertop. For safe airflow and stability, we recommend using a true countertop model like Whirlpool GT4175SPS2 and following the placement clearances in the owner's manual.
Over-the-range microwaves rely on a mounting bracket and upper cabinet support, and they are built to vent and manage heat in that installed position. Setting one on a counter can create airflow restrictions, tipping risk, and heat exposure issues.
Use these setup rules to avoid overheating and nuisance shutoffs:
- Set the microwave on a cart, counter, table, or shelf strong enough to support the unit plus food and cookware.
- Keep the microwave legs in place; they help maintain proper airflow.
- Do not block exhaust vents or air intake openings.
- Leave a few inches of space behind the unit where exhaust vents are located.
- Do not place the microwave near water (sink, wet basement) and keep the cord away from heat.
- Do not store items on top of the microwave while it is operating.
| Feature | Over-the-range microwave | Countertop microwave (GT4175SPS2) |
|---|---|---|
| Intended location | Above a range | On a counter/shelf/cart |
| Support method | Bracket and cabinet mounting | Feet on a flat surface |
| Airflow design | Assumes installed clearances | Assumes open counter clearances |
| Best use case | Built-in kitchen layout | Flexible placement |
Microwaves need consistent airflow to prevent heat damage and automatic thermal shutdowns. Using the correct style for the location also reduces the chance of the unit shifting, falling, or operating with blocked vents.

What are the dimensions of GT4175SPS2?
The Whirlpool GT4175SPS2 countertop microwave measures about 22 19/32 in. wide, 13 17/32 in. high, and 17 5/16 in. deep. For the most accurate fit (including door clearance and ventilation space), confirm the cutout and clearance notes in the owner's manual.
| Measurement | Size |
|---|---|
| Width | 22 19/32 in. |
| Height | 13 17/32 in. |
| Depth | 17 5/16 in. |
- Measure the countertop footprint (width and depth) where the microwave will sit.
- Add at least 1 to 2 inches behind the unit for cord routing and airflow.
- Allow door swing clearance in front so the door opens fully without hitting a backsplash or cabinet.
- If placing under cabinets, leave top clearance so heat can vent properly.
- If you plan to build it in, use an approved trim kit and follow the spacing rules in the manual.
Microwave dimensions affect more than just whether it fits on the counter. Clearance impacts ventilation, door operation, and safe operation, especially if the unit is placed in a tight cabinet opening.
If the unit fits but the door does not close or latch correctly after moving it, these model-compatible parts are common fixes:
- Microwave door 8205518
- Microwave door release lever WP8205451
- Microwave door primary interlock switch 4392027

What is the best Countertop Microwave oven?
The “best” countertop microwave depends on what you cook most and the features you will actually use. For everyday reheating and simple cooking, a reliable 0.9 to 1.3 cu. ft. countertop microwave with a turntable, multiple power levels, and easy controls is the best fit for most kitchens; use your owner's manual to match cookware and safe-use rules to your Whirlpool GT4175SPS2.
Focus on performance and usability first, then size and features.
- Capacity: 0.9 to 1.3 cu. ft. fits most plates and bowls; 1.4+ cu. ft. is better for larger dishes.
- Power: Most homes do well with 900 to 1200 watts for faster heating and better results.
- Cooking controls: Look for multiple power levels and stage cooking (useful for defrost then cook).
- Sensor cooking: Helpful for popcorn and reheats, but only if you use it often.
- Interior and turntable: A stable turntable improves even heating; replace a chipped or broken one.
- Door and safety interlocks: A solid door latch feel matters; door issues can stop the microwave from running.
| If you want... | Prioritize... | Why it matters |
|---|---|---|
| Even reheating | Multiple power levels, turntable | Reduces hot spots and overcooking |
| Convenience | Sensor cook, presets | Less guesswork for common foods |
| Small footprint | 0.7 to 1.0 cu. ft. | Fits apartments, dorms, tight counters |
| Long-term reliability | Simple controls, good door/latch feel | Fewer failure points |
Even a top-rated microwave performs poorly with the wrong cookware or habits.
- Use cookware that fits on the turntable and is microwave-safe.
- Avoid gold or silver trim; avoid materials the manual lists as “do not use.”
- Do not run the microwave empty.
- Use the manual’s “test cookware” method (water stays cool means the dish is not suitable).
Microwaves vary more in usability and real-world heating than in brand name. Choosing the right size, wattage, and controls for your cooking style gives better results and fewer frustrations than chasing a single “best” model.
