Samsung ME20H705MSS/AA-00 microwave/hood combo Parts

The Samsung ME20H705MSS microwave/hood combo is a 1000-watt microwave (power output). In the specifications, it also lists 1700 watts for power consumption, which is the electrical draw while operating (not the cooking power). See the owner's manual for the full spec table.

Watts explained (output vs. consumption)

Microwaves commonly list two different watt numbers; they mean different things:

• Power output (cooking power): how much microwave energy heats food (ME20H705MSS: 1000 W)
• Power consumption (input draw): how much electricity the unit uses while running (ME20H705MSS: 1700 W)
• Circuit planning: consumption matters for outlets and breakers; output matters for cooking performance
• Cooking time: higher output usually means faster heating for the same food load

Quick spec snapshot for ME20H705MSS

Spec	Value
Power output (microwave cooking power)	1000 watts
Power consumption (electrical draw)	1700 watts
Power source	120 VAC, 60 Hz
Oven capacity	2.0 cu ft

Why it matters

Using the correct watt number helps you set expectations. 1000 watts output tells you how quickly it should heat common items (water, leftovers, frozen meals). 1700 watts consumption helps you avoid nuisance trips by keeping the microwave on a properly rated kitchen circuit.

Parts and performance notes

If your ME20H705MSS runs but does not heat like a 1000-watt microwave, common heating-system parts to check include:

• Microwave magnetron OM75P-21-ESGN (creates microwave energy)
• Microwave high-voltage diode DE91-70063D (part of the high-voltage circuit)
• Microwave high-voltage capacitor 2501-001011 (stores high voltage for the magnetron)
• Microwave high-voltage transformer DE26-00126B (steps voltage up for the high-voltage system)

For broader troubleshooting steps, we recommend why is my microwave not heating.

On a Samsung ME20H705MSS microwave/hood combo, an SE error is typically caused by the control panel sensing a stuck key or false keypad input. We fix it by safely power-resetting the unit, drying and cleaning the keypad area, then checking for a door-switch or control issue if the code returns (see the ME20H705MSS owner's manual).

Quick fixes to try first (in order)

• Unplug the microwave (or switch off the breaker) for 2 to 3 minutes, then restore power.
• Wipe the control panel and surrounding trim with a soft, dry cloth (remove grease and moisture).
• Leave the door open for 10 to 15 minutes to help any trapped moisture evaporate.
• Confirm the door closes firmly and latches normally (a mis-latched door can confuse inputs).
• If the SE code returns immediately, stop using the microwave until the cause is corrected.

What usually causes the SE error

Likely cause	What you’ll notice	What typically fixes it
Moisture, cleaner residue, or grease on the keypad	SE appears after cleaning or cooking steam	Dry-clean the panel; avoid spraying cleaners directly
Stuck or shorted keypad/control panel circuit	SE returns right after reset	Control panel or control board diagnosis
Door interlock issue (door not “seen” as closed)	Random beeps, won’t start, or error after closing door	Inspect/replace door switch or support

Parts that commonly relate to this symptom

If the error persists after cleaning and a power reset, these model-matched parts are commonly involved in “keypad/door input” problems:

• Microwave door interlock switch 3405-001034 (door sensing)
• Microwave door interlock support DE96-00414D (switch mounting and alignment)
• Microwave electronic control board DE92-03624C (interprets keypad and switch signals)

Why it matters

An SE error can prevent safe operation because the microwave may interpret a key as continuously pressed or misread door status. The manual also emphasizes that internal adjustments and repairs should be handled by properly qualified service personnel, especially on high-voltage appliances.

The most common issues we see with the Samsung ME20H705MSS microwave/hood combo are no heat, intermittent operation, a dead display or keypad, turntable problems, and vent fan or light issues. Many of these symptoms trace to door interlocks, high-voltage components, or the control board; use the ME20H705MSS owner's manual for model-specific checks and settings.

Common symptoms and likely causes

• Microwave runs but does not heat: magnetron, high-voltage diode, high-voltage capacitor, or high-voltage transformer
• Starts then stops, or blows a fuse/breaker: door interlock switch or interlock alignment issues
• No power, blank display: power cord connection, noise filter, or electronic control board
• Turntable not rotating: turntable motor or tray/roller alignment
• Vent fan noisy or not working: vent fan motor assembly or blocked venting
• Surface light not working: bulb or lens/holder issues

Parts that commonly fix these problems (for ME20H705MSS)

If your symptom matches, these model-listed parts are frequent repair solutions:

Symptom	Part to check	What it does
No heat	Microwave magnetron OM75P-21-ESGN	Generates microwave energy for heating
No heat	Microwave high-voltage diode DE91-70063D	Converts AC to DC for the high-voltage circuit
Starts then stops	Microwave door interlock switch 3405-001034	Confirms the door is closed so heating can run
Dead display or erratic controls	Microwave electronic control board DE92-03624C	Manages keypad, display, and cooking functions
Turntable not moving	Microwave turntable motor DE31-10172C	Rotates the turntable during cooking

Quick checks we recommend before replacing parts

• Confirm the unit is plugged in firmly and the outlet has power.
• Test with a cup of water for 60 seconds; note whether it heats, hums, or stops early.
• Open and close the door slowly; listen for distinct interlock “clicks.”
• Make sure the turntable tray is seated correctly and not binding.
• Check that the vent grille is not blocked by grease buildup.

Why it matters

A microwave/hood combo uses door interlocks and high-voltage components to heat safely. When an interlock, control board, or high-voltage part fails, the microwave may run without heating, stop mid-cycle, or appear completely dead.
