Kenmore 20479393610 microwave Parts

Yes. On many Kenmore countertop microwaves, including model 20479393610, the practical “reset” is a power reset: unplug the microwave (or switch off the breaker), wait about 1 minute, then restore power and re-set the clock. For model-specific control settings, use the owner's manual.

Quick reset options (what to try first)

• Power reset: Unplug for 60 seconds, then plug back in.
• Breaker reset: If it is hardwired to a dedicated circuit, switch the breaker off for 60 seconds, then back on.
• Clear a stuck cooking cycle: Press STOP/CANCEL once; press again to clear the display.
• Re-set the clock: After power is restored, set the time so timed features work correctly.

When a reset helps (and when it will not)

A reset is most useful for a frozen keypad, a display glitch, or after a brief power outage. It will not fix a true heating or power problem such as a blown fuse, door-switch issue, or high-voltage component failure.

Symptom	Reset likely to help?	What to do next
Display is blank after outage	Yes	Power reset; then set clock in the owner's manual
Keypad not responding	Sometimes	Power reset; check for stuck keys or moisture
Runs but does not heat	No	Follow why is my microwave not heating troubleshooting
Dead, no lights, no fan	Sometimes	Power reset; then check fuse and power supply path

Why it matters

Resetting clears temporary control-board errors and restores normal operation after power interruptions. If the microwave still will not run or will not heat after a reset, troubleshooting the power path (cord, outlet, fuse, door switches) and heating system is the next step.

For the Kenmore countertop microwave model 20479393610, the internal line fuse is typically a ceramic 20-amp, 250-volt microwave fuse. Use the exact fuse type and rating listed in the 20479393610 owner's manual to match the original safety design.

What to use (and what not to use)

Microwaves use a ceramic fuse because it handles high inrush current and contains arc energy better than glass fuses.

• Use a ceramic microwave fuse (not glass)
• Match the amperage (20A) and voltage rating (commonly 250V)
• Match the physical size (length and diameter) to the original fuse
• Replace a blown fuse only after checking for the cause (door switch, shorted component, wiring)
• Never bypass the fuse or install a higher-amp fuse

Common symptoms of a blown microwave fuse

A blown fuse often shows up as a total power loss, but it can also fail after a door-slam or a short.

• Microwave is completely dead (no display, no interior light)
• Unit goes dead when you press Start
• Unit goes dead when opening or closing the door
• Intermittent power, especially after moving the microwave

Quick troubleshooting path (before replacing the fuse)

1. Confirm the outlet has power (try a lamp or small appliance).
2. Reset the kitchen circuit breaker or GFCI if tripped.
3. If the microwave is dead but the outlet is good, inspect and test the fuse and door interlock switches.

Fuse sizing and selection checklist

What must match	Target for this model	Why it matters
Fuse type	Ceramic microwave fuse	Prevents arcing and overheating
Amperage	20A	Protects wiring and high-voltage components
Voltage rating	250V (typical)	Ensures safe interruption under load
Physical size	Match original	Ensures proper fit in the holder

Why it matters

The fuse is the microwave’s primary overcurrent safety device. Using the wrong fuse type or rating can cause repeat failures, damage to the control circuit, or unsafe overheating.

Kenmore microwaves are a solid choice for everyday reheating and cooking when you match the features and size to how you actually use the microwave. For Kenmore model 20479393610, the owner's manual shows it is a 2.2 cu. ft., 1250-watt output countertop unit, which is a strong spec for fast, even heating.

What “good” means for a microwave

A microwave is “good” when it consistently heats, fits your space, and holds up to normal use without frequent issues.

Key things we look for:

• Heating performance: steady power and even results
• Capacity and fit: enough room for your dishes (this model is 2.2 cu. ft.)
• Ease of use: clear controls, sensible presets
• Reliability basics: door closes correctly, fan vents stay clear, turntable runs smoothly
• Safe operation habits: correct cookware and no metal in the cavity

Model 20479393610 quick specs (from the manual)

Spec	What it means for you
1250W rated output	Faster heating than many 900 to 1100W units
2.2 cu. ft. capacity	Roomier interior for larger plates and bowls
16.54 in turntable	Helps rotate food for more even heating
14.17 x 24.72 x 20.71 in (H x W x D)	Check counter depth and clearance before buying

How to keep a Kenmore microwave “good” over time

These habits prevent many common complaints (weak heating, uneven cooking, arcing, and nuisance shutdowns):

• Use microwave-safe cookware and avoid metal or foil contact
• Keep ventilation ports clear so heat can escape
• Wipe the door sealing surfaces with mild soap and a soft cloth
• Use the right power level (not always 100%) for delicate foods
• Stir or rotate food mid-cycle for more even results

Why it matters

Most “bad microwave” experiences come from a mismatch (too small, too low wattage) or from use and care issues (blocked vents, wrong cookware, overheated food). With 1250W output and a large cavity, model 20479393610 is built for strong day-to-day performance when used as directed.

The Kenmore countertop microwave model 20479393610 has an oven capacity of 2.2 cubic feet. This is the usable cooking-space size inside the cavity (not the outside dimensions), and it helps you judge what dish sizes and cookware will fit.

Where to confirm the capacity for your exact model

We list the capacity and other key specifications in the 20479393610 use and care guide. Look for the Specifications section, where “Oven Capacity” is shown.

What 2.2 cu. ft. means in everyday use

A 2.2 cu. ft. countertop microwave is considered a larger-capacity unit. In most kitchens, that capacity is a good fit for family-size reheating and larger microwave-safe containers.

Common fit and use expectations:

• Handles larger dinner plates and many casserole-style dishes
• Gives more clearance for taller microwave-safe bowls
• Works well for batch reheating (multiple portions)
• Still needs proper airflow clearance around the cabinet for venting

Quick spec snapshot (from the manual)

Spec	What to expect for model 20479393610
Oven capacity	2.2 cu. ft.
Rated output power	1250 W
Turntable diameter	16.54 in.
External dimensions	14.17 x 24.72 x 20.71 in.

Why it matters

Capacity affects more than “how much fits.” It also impacts countertop space planning, turntable size, and which cookware shapes rotate without hitting the walls. If you are troubleshooting uneven heating, cookware size and placement can be part of the cause.

If your Kenmore microwave model 20479393610 suddenly stopped working, the most common causes are a loss of power to the unit, the control being locked, or a safety device (like a fuse or thermal cutoff) opening after an overheat or electrical surge. Start with the quick checks below before moving to electrical testing.

Quick checks we recommend first

• Confirm the outlet works by plugging in a lamp or small appliance.
• Reset the kitchen circuit breaker or replace the blown house fuse.
• Make sure the door closes fully and latches firmly (a mislatched door can prevent operation).
• Check for Control Lock: press and hold the lock pad for 3 seconds until “LOCK” disappears. See the owner's manual.
• If the display shows an error like E-5 during sensor cooking, press the stop/clear pad to reset, then try again (opening the door during sensor cooking can stop the cycle). See the owner's manual.

If it has power but will not run or heat

Microwaves can appear “dead” or run without heating when a protective fuse opens or a high-voltage component fails. Because internal microwave components can store dangerous voltage even when unplugged, we recommend having a qualified technician handle internal diagnosis.

Common symptoms and likely areas to check:

What you notice	What it often points to	What to do next
No display, no response	No power, blown internal fuse, thermal cutoff open	Verify outlet and breaker; then schedule service for internal checks
Runs (light/turntable/fan) but no heat	High-voltage circuit issue (diode, capacitor, magnetron) or related fuse	Use our troubleshooting guide: why is my microwave not heating
Stops mid-cycle, beeps, returns to standby	Sensor-cook interruption or door opened	Avoid opening door during sensor cooking; vent covers properly

Why it matters

A microwave that “stops working” is often protecting itself. Restricted ventilation, repeated overheating, or a power surge can open a fuse or thermal cutoff; continuing to reset and retry can lead to repeat failures.

Prevention tips for this model

• Keep ventilation ports clear; do not block airflow around the cabinet.
• Use microwave-safe cookware and keep the cavity and tray dry.
• During sensor cooking, use a vented cover and avoid opening the door early (it can stop the sensor cycle).
