Frigidaire FGMV176NTDB microwave/hood combo Parts

Yes. A 1.6 cu. ft. microwave is considered a larger, family-friendly size that fits most dinner plates and medium casserole dishes. For the Frigidaire FGMV176NTDB specifically, the rated capacity is 1.7 cu. ft., which is firmly in the full-size over-the-range range (see the owner's manual).

What “big” means in real use

A 1.6 to 1.7 cu. ft. microwave/hood combo typically handles everyday cooking and reheating without feeling cramped.

• Fits most standard dinner plates and microwave-safe bowls
• Better for multi-serving leftovers than compact models
• More comfortable clearance for taller containers (within reason)
• Common choice for families and frequent cooks
• Still smaller than extra-large countertop units (around 2.0+ cu. ft.)

FGMV176NTDB size details (from the specs)

Here are the key published dimensions for this model.

Spec	FGMV176NTDB value
Microwave capacity	1.7 cu. ft.
Cavity dimensions (W x D x H)	20.94 in. x 9.57 in. x 14.43 in.
Outside dimensions (W x D x H)	29.88 in. x 15.04 in. x 16.41 in.

Quick way to decide if it is “big enough” for you

We recommend checking the dish you use most often and comparing it to the cavity width and depth.

• Measure your largest plate or casserole (diameter and height)
• Confirm it can rotate freely on the turntable
• Leave at least 1 inch of clearance from the side walls when possible
• Avoid forcing oversized dishes that stop the turntable

Why it matters

Microwave capacity (cu. ft.) is a helpful headline number, but cavity dimensions and turntable clearance determine what actually fits. A “big” microwave that cannot rotate your favorite dish will heat less evenly and can strain the turntable system.

A Frigidaire microwave, including the FGMV176NTDB microwave/hood combo, typically lasts 9 years. With normal daily use and basic care (keeping it clean, using proper cookware, and avoiding overheating), 7 to 10 years is the expected lifespan.

Typical lifespan ranges (what we see most often)

• Light use (occasional reheating): 10 to 12 years
• Average use (daily cooking/reheating): about 9 years
• Heavy use (multiple cycles per day): 5 to 7 years
• Hard-use conditions (poor ventilation, frequent overheating): 4 to 5 years

What shortens the life of a microwave fastest

• Running the microwave empty
• Repeatedly overheating foods until the cavity gets excessively hot
• Slamming the door or forcing a misaligned latch
• Ignoring arcing, burning smells, or unusual buzzing
• Poor airflow around an over-the-range unit (blocked vents or greasy filters)

Maintenance that helps your FGMV176NTDB last longer

Use the care and cleaning guidance in the FGMV176NTDB owner's manual.

• Wipe the cavity and door seals regularly to prevent buildup
• Keep the vent area clean so heat can escape properly
• Use microwave-safe containers (no metal, no foil contact)
• Stop cooking and stir or rotate food to prevent localized overheating
• Address door-closing issues early (latch and switch alignment matters)

Repair vs. replace: a quick rule of thumb

If your microwave is...	We recommend...
Under 7 years old	Repair is usually worth considering
7 to 10 years old	Compare repair cost to replacement value
Over 10 years old	Replace unless the fix is simple and low-cost

If the unit won’t start or stops when the door moves, the door safety circuit is a common place to check; for this model, parts like the crosley microwave door interlock switch 5304509460 are listed for FGMV176NTDB.

Why it matters

Microwaves tend to fail in predictable areas (door interlock switches, thermostats, control components, or high-voltage parts). Knowing the normal lifespan helps you decide whether a symptom is a quick fix or a sign the unit is nearing end-of-life.

A Frigidaire FGMV176NTDB microwave/hood combo usually stops working because it lost power, the door interlock system is not proving the door is closed, or a protective device (like a fuse or thermal cut-off) opened after an electrical or overheating event. Start with power checks, then focus on the door latches and switches.

Quick checks we recommend first

• Confirm the outlet has power (try a lamp or small appliance).
• Check the kitchen breaker and any wall switch that controls the microwave outlet.
• Unplug the microwave for 60 seconds, then plug it back in to reset the control.
• Make sure the door closes firmly and is not sagging or rubbing.
• Verify the vent openings are not blocked (restricted airflow can lead to overheating).

Most common causes (and what they look like)

Symptom	Most likely cause	What to check next
Completely dead (no display)	No power, blown fuse, open thermal cut-off	Outlet, breaker, then internal protection devices
Runs but stops when door moves	Door switch or latch issue	Door hooks, latch body, interlock switches
Display works but won’t start	Door not “seen” as closed	Interlock switches and switch lever alignment
Runs but doesn’t heat	High-voltage circuit issue	Diode, capacitor, transformer (high-voltage components)

Model-specific parts that commonly relate to “stopped working”

On model FGMV176NTDB, door-interlock problems are a frequent reason a microwave will appear dead or refuse to run. These parts are commonly involved:

• Microwave door interlock switch 5304509459 (a failed switch can prevent operation)
• Microwave latch body 5304509457 (worn or broken latch parts can keep switches from actuating)
• Microwave thermal cut-off 5304509469 (opens if overheating occurs)

For operating and troubleshooting guidance, use the owner's manual.

Why it matters

Microwaves use a door interlock system to prevent operation with the door open, and they also use thermal protection to shut the unit down if it overheats. Fixing the root cause (door alignment, airflow, or a failed switch) prevents repeat shutdowns and nuisance “dead” symptoms.

Ordering the right replacement part

We recommend matching parts by the full model number (FGMV176NTDB) and comparing the part ID before ordering. You can order from the parts list for this model, or search by model number on Sears PartsDirect.
