Kenmore Elite 40574159310 microwave Parts

To reset your Kenmore Elite microwave model 40574159310, stop any active cooking and clear the control settings; on this model, pressing STOP/CLEAR (sometimes labeled Cancel) clears previous entries and returns the oven to an idle display. For model-specific keypad behavior, follow the steps in the 40574159310 owner's manual.

Quick reset steps (most common)

• Press STOP/CLEAR once to stop cooking.
• Press STOP/CLEAR a second time to clear the programmed settings.
• If the display is unresponsive, open and close the door, then press STOP/CLEAR again.
• If LOC shows on the display, turn off the control lock (see below).
• Re-set the clock if needed.

If the control lock is on (LOC)

This model includes a child lock feature that prevents operation.

• Press and hold STOP/CLEAR for 3 seconds.
• Wait for the long beep.
• Confirm LOC disappears.

Power reset (when the keypad is frozen)

If clearing does not restore normal operation, a power reset often restores the control board.

• Unplug the microwave (or switch off the circuit) for 2 to 5 minutes.
• Plug it back in.
• Confirm the display returns (often shows 0:00), then set the clock.

Reset type	What it fixes	What you will lose
STOP/CLEAR reset	Wrong settings, stuck program, canceled cook cycle	Current cook settings only
Control lock off	“LOC” and locked keypad	Nothing (just unlocks)
Power reset	Frozen display, non-responsive keypad	Clock time and any temporary settings

Why it matters

A proper reset clears incorrect cooking programs and helps you quickly identify whether the issue is a simple control setting (like LOC) or a power/control problem that needs troubleshooting.

For your Kenmore Elite microwave model 40574159310, the model number is printed on the rating label. You’ll usually find it around the door opening or on the back of the cabinet; match the full number exactly when ordering parts or checking specs in the 40574159310 owner’s manual.

Most common model number label locations

Check these spots first (in order):

• Door frame: open the door and look along the front frame of the microwave.
• Inside edge of the door: sometimes the label is on the door itself.
• Control panel area: along the side trim near the keypad.
• Back panel: on the rear of the outer cabinet.
• Interior side wall: less common, but possible on some countertop units.

What the label looks like (and what to write down)

The rating label typically includes several identifiers. Use this quick guide:

Label item	What it’s used for	Example for this unit
Model number	Correct parts and documentation	40574159310
Brand name	Confirms product line	Kenmore Elite
Electrical rating	Outlet and circuit checks	120V household circuit (typical)

Why it matters

Using the exact model number helps us show the right Kenmore Elite microwave parts and diagrams for your unit. Even small model number differences can change the glass tray fit, door switches, or internal components.

Parts tip (if you’re replacing a broken tray)

If your turntable tray is cracked or missing, confirm the model number first, then match the part by ID:

• Midea microwave glass tray F06015Q00AP (part number 252100500011) is listed for model 40574159310.

The Kenmore Elite 40574159310 countertop microwave has an oven capacity of 1.5 cu. ft. (about 42 L), as listed in the specifications in the 40574159310 use and care guide.

Where to confirm the capacity (and why it can look different)

Capacity is usually listed in the specifications section of the manual. If you see a different number online, it is often because a similar-looking model in the same series is being referenced.

• Look for “Oven Capacity” in the specs table
• Match the full model number: 40574159310 (not just “405.7415…”)
• Use the manual’s capacity for the most accurate value
• If you are comparing microwaves, compare capacity and turntable diameter together

Quick specs snapshot for this model

Spec	Value
Oven capacity	1.5 cu. ft. (42 L)
Turntable diameter	13.6 in (345 mm)
Rated output power (microwave)	1000 W

Why it matters

Capacity affects what fits (casserole dishes, dinner plates) and how evenly food heats. For day-to-day use, pairing the 1.5 cu. ft. cavity with the 13.6-inch turntable gives a better real-world idea of usable space than capacity alone.

If your Kenmore Elite microwave model 40574159310 will not turn on, start with the basics: confirm the outlet has power, the cord is fully plugged in, and the door is completely closed. If it still stays dead, a blown internal fuse or failed door interlock is a common cause.

Quick checks we recommend first

• Plug a lamp or phone charger into the same outlet to confirm power.
• If you use a power strip, plug the microwave directly into the wall outlet.
• Open and firmly close the door; a partially latched door can prevent operation.
• Try a different cook setting after clearing the keypad (wait 30 seconds unplugged, then restore power).
• If the display shows 0:00, set the clock and try again (some models behave differently after a power loss).

Most common parts and failures (what they affect)

Symptom	Most likely area	What it means
No display, no interior light, no response	Line fuse or thermal cutout	Power is being interrupted inside the microwave
Display works but it will not start	Door switches (interlock)	Microwave thinks the door is open or unsafe
Starts then stops quickly	Door alignment or interlock issue	Latch is not staying engaged

Safe troubleshooting notes (important)

Microwaves contain high-voltage components that can retain a dangerous charge even when unplugged. For internal electrical testing (fuse, thermal cutout, door switches), we recommend using a qualified service technician.

If you are doing basic diagnostics only, use the troubleshooting chart in the 40574159310 use and care guide and follow these safety reminders:

• Do not operate the microwave with the door open or if the door does not close properly.
• Do not defeat or tamper with the safety interlocks.
• Do not use the microwave if the door, hinges, latches, or seals are damaged.

When a part replacement makes sense

If your microwave runs but the turntable tray is missing, chipped, or not sitting correctly, replacing the tray helps prevent breakage and improves heating consistency. For this model, we list the midea microwave glass tray F06015Q00AP.

Why it matters

A microwave that will not power up or will not start is often protecting you by stopping operation when it detects an unsafe door condition or an internal overheat or power interruption. Fixing the root cause restores normal operation and helps prevent arcing, overheating, and repeat fuse failures.

If the display on your Kenmore Elite microwave model 40574159310 is blank or unresponsive, the most common causes are a temporary control lock setting, a power supply issue (outlet, cord, or internal fuse), or a problem with the control panel circuitry. Start with the quick checks below before planning a repair.

Quick checks we recommend first

• Make sure the microwave is fully plugged into a working, properly grounded outlet (try a different small appliance in the same outlet).
• Check for Control Lock: if you see “LOC” on the display, press and hold the lock pad for 3 seconds to unlock.
• Open and close the door firmly, then try a basic cook cycle; the door must be closed for the oven to start.
• Power reset: unplug for about 5 minutes, then plug back in and check the display.
• If the display comes on but keys do not beep or respond, the keypad or control board connection can be the issue.

What the display symptoms usually mean

Symptom	Most likely cause	What to do next
Completely blank, no beeps	No power or blown internal fuse	Verify outlet, then move to fuse testing and service steps
“LOC” shows	Control lock enabled	Unlock using the lock pad (hold 3 seconds)
Display works, keypad does not	Keypad (membrane) or ribbon connection issue	Inspect for stuck keys; reseat ribbon if accessible
Random characters or intermittent display	Control board problem or unstable power	Reset; if it returns, plan for control repair

Safe troubleshooting and repair guidance

Microwaves contain high-voltage components; we recommend leaving internal electrical diagnosis to a qualified service person.

• Follow the safety and operating guidance in the 40574159310 owner’s manual.
• If you suspect a fuse issue, use our how to replace a microwave fuse guide to understand the process and safety steps.
• If the unit powers on but will not heat (sometimes confused with “not working”), use why is my microwave not heating to narrow down likely causes.

Why it matters

A dead display can be as simple as Control Lock, but it can also indicate a power or control failure that prevents safe operation. Confirming the symptom pattern helps you avoid unnecessary parts replacement and reduces the risk of electrical hazards.
