What size is the Frigidaire Model FFMv164LSA?
The Frigidaire FFMV164LSA is an over-the-range microwave/hood combo designed to fit a standard 30-inch wide cabinet space. Per the model’s specifications, the outside dimensions (including handle) are 29.88 in. wide x 15.75 in. high x 15.04 in. deep, with a 1.6 cu. ft. capacity.
These specs are listed in the FFMV164LSA use & care manual.
- Outside dimensions (including handle): 29.88 in. (W) x 15.75 in. (H) x 15.04 in. (D)
- Cavity dimensions: 20.24 in. (W) x 8.94 in. (H) x 14.41 in. (D)
- Microwave capacity: 1.6 cu. ft.
- Output power: 1000 W
The “30-inch” description is about the cabinet opening width the unit is intended to mount under, not the exact outside width.
| Spec | Value for FFMV164LSA | Why it matters |
|---|---|---|
| Nominal cabinet width | 30 in. | Confirms it’s an over-the-range size class |
| Actual outside width | 29.88 in. | Confirms the unit’s physical width |
| Outside height | 15.75 in. | Helps verify vertical clearance |
Use the installation guide to confirm clearances, mounting height, and venting configuration.
- Cabinet opening width requirements
- Minimum clearance above the cooktop
- Venting type: outside top, outside back, or recirculating
- Power supply location and grounding requirements
For those details, use the FFMV164LSA installation instructions.
Using the model-specific width, height, and depth helps prevent cabinet-fit surprises and supports proper venting alignment and safe mounting above your range.

Can you reset a Frigidaire microwave?
Yes. For the Frigidaire FFMV164LSA microwave/hood combo, the simplest reset is a power reset: unplug the microwave (or switch off the breaker) for about 10 seconds, then restore power and reset the clock as needed. See the FFMV164LSA use & care manual for control-panel steps.
- Press Stop/Cancel once to stop cooking; press twice to cancel a program.
- If the control panel is unresponsive, unplug the microwave (or turn off the circuit breaker).
- Wait about 10 seconds.
- Restore power.
- Set the clock again (Clock, enter time, Clock).
A “reset” will not fix every issue. If the display is on but buttons do not work, or the unit acts locked, check these common causes:
- Control lock is on (hold Stop/Cancel for more than 3 seconds to toggle).
- Power supply issue (tripped breaker, loose outlet, shared circuit problems).
- Door not fully latching (the door must close firmly for the interlock system to allow operation).
- Internal protection device opened after a surge or overheating.
If the microwave is completely dead (no display) after confirming the outlet has power, these model-compatible parts are commonly checked by a technician:
- Fuse 5304509451 (opens to protect the microwave during a power surge)
- Microwave door interlock switch 5304509460 (prevents operation if the door is not safely closed)
- Microwave thermal cut-off 5304509475 (opens if overheating occurs)
| What you see | What to try first | What it can indicate |
|---|---|---|
| Display works, cooking will not start | Check door closure; cancel and re-enter cook time | Door/interlock issue or user setting |
| “Locked” behavior, buttons seem ignored | Toggle control lock (hold Stop/Cancel 3+ seconds) | Control lock enabled |
| No display at all | Verify outlet power; power reset | Power supply, fuse, or thermal cut-off |
Resetting clears temporary control glitches and restores normal operation after a brief power interruption. If the problem returns, it often points to a door-latch/interlock, overheating, or an electrical protection part rather than the control settings.

How do I turn off the beep on my Frigidaire ffmv164lsa?
On the Frigidaire FFMV164LSA microwave/hood combo, the keypad and end-of-cycle beeps can’t be turned off through a user setting. The control panel functions shown in the FFMV164LSA use & care manual include clock, timer, power levels, and control lock, but no sound or mute option.
If the beeps are bothering you, these are the most practical workarounds that don’t rely on undocumented button sequences:
- Press Stop/Cancel once to clear the display after cooking finishes.
- Remove food promptly to avoid repeated reminder beeps (if your unit is set up to remind).
- Use shorter cook times and add time as needed with START/+30 sec.
- If you mainly hear beeps from the timer, use the microwave timer only when you need an audible alert.
| When you hear it | What it usually means | What to do |
|---|---|---|
| Beeps at the end of cooking | Cook cycle finished | Open door or press Stop/Cancel |
| Beeps when the timer ends | Timer finished | Press Stop/Cancel to clear |
| Two beeps during defrost | Turn/adjust food reminder | Turn food, then press START/+30 sec |
Microwave beeps are a safety and usability feature; they confirm keypad presses and signal end-of-cycle so food isn’t left overheating or forgotten.
If the microwave beeps randomly (not tied to a timer, cook cycle, or defrost prompt), that’s typically a control or input issue rather than a “sound setting.” In that case:
- Unplug the microwave for 1 minute, then restore power and retest
- Make sure no keys are stuck or the control panel isn’t being pressed by a cleaner residue
- If the unit won’t start or acts erratic when the door moves, inspect the door latching parts such as the microwave door interlock switch 5304509460

What is the average life of a Frigidaire microwave?
Frigidaire doesn’t list an “average life” expectancy for the Frigidaire FFMV164LSA microwave/hood combo in the model documentation. In real-world use, lifespan varies widely; consistent cleaning, proper ventilation, and avoiding misuse typically help a microwave last longer.
The model’s documentation provides operating, cleaning, and safety guidance plus specifications, but it does not provide a service-life estimate. For model-specific care and maintenance steps, use the FFMV164LSA use & care manual.
- Keeping ventilation openings and grease filters clean
- Not running the microwave empty (helps protect internal components)
- Preventing arcing (avoid metal, keep the waveguide area clean)
- Closing the door gently and keeping latches aligned
- Using a properly grounded outlet (no extension cord)
Because there’s no fixed “average,” we recommend deciding based on the symptom, safety, and repair scope.
| What you notice | What we recommend first | Why it matters |
|---|---|---|
| Dead display or no power | Verify outlet, breaker, and power cord connection | Rules out a home power issue before any repair |
| Runs but won’t heat | Stop using and have it diagnosed by a qualified technician | Heating circuits involve high voltage |
| Won’t start unless door is pressed | Check door alignment and latch operation | Door interlocks are a critical safety system |
| Burning smell or arcing | Stop using immediately and inspect for splatter or damage | Continued use can damage the cavity and parts |
We can’t diagnose a specific failed part from lifespan alone, but these are examples of components customers often replace when symptoms occur:
- Fuse 5304509451 (power protection device)
- Microwave door interlock switch 5304509460 (door safety switch)
- Microwave electronic control board 5304477390 (controls keypad and operation)
Microwaves often show early warning signs (longer cook times, intermittent starting, unusual noises). Addressing cleaning and ventilation early can help prevent secondary issues and keep performance consistent.
