SE
Whirlpool SE on a microwave: keypad or wiring problem
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On a Whirlpool over-the-range microwave, SE indicates a problem with the keypad (user interface) or its wiring. Whirlpool says to switch the breaker off for one minute, back on, watch for one minute and test operation.
Safety first
Stop and check this first
- An over-the-range microwave is not taken apart to check boards or wires: the high voltage capacitor can keep a lethal charge even with the power off. Magnetron, door seals and safety interlocks are for authorised service only.
Safe checks you can perform
- Dry panel with nothing pressing it
- Breaker off for one minute
- Operating test with a load
Leave these tasks to a qualified professional
- Do not attempt this professional task: Keypad and cable diagnosis
- Do not attempt this professional task: Final controls check
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Keypad and cable diagnosis
What they doThe authorised technician tests the keypad and checks the connector and cable to the board with the service manual, after discharging high voltage.
They must show youthe check that identifies the failing part.
In writingwhat was replaced, its part number and why.
Final controls check
What they doAfter the repair, the technician uses every panel function and runs a cycle with a load.
They must show youthe panel responding and the full cycle.
In writingthe functions tested, the result and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Dry panel with nothing pressing it
- Who:
- you, no tools.
- How:
- check that the control panel is dry and nothing is pressing it, such as a hanging utensil or condensed steam.
- Result that matters:
- whether something on the keypad explains the code.
- If there was moisture or something resting on it:
- remove it and move on to the breaker cut.
- If nothing there:
- the origin is the keypad or its wire, or it was a passing glitch.
- Evidence to keep:
- photo of the panel.
Evidence: SE - Error Code - Over-the-Range Microwave
Breaker off for one minute
- Who:
- you, at the breaker panel and without opening the unit.
- How:
- switch the microwave's breaker or breakers off for one minute, switch them back on and watch the display for another minute, as Whirlpool says.
- Result that matters:
- whether SE reappears within that minute.
- If it does not return:
- it was a passing glitch; test operation as Whirlpool asks.
- If it returns:
- Whirlpool points to service to check keypad and wiring.
- Evidence to keep:
- time of the cut and whether the code came back during the minute.
Evidence: SE - Error Code - Over-the-Range Microwave
Operating test with a load
- Who:
- you, with a microwave-safe container of water.
- How:
- place a microwave-safe container of water inside and set a short time using the keypad. Do not run it empty.
- Result that matters:
- that it accepts commands and heats without SE.
- If it works:
- solved.
- If SE returns:
- call service with your notes.
- Evidence to keep:
- note of when SE reappears.
Evidence: SE - Error Code - Over-the-Range Microwave
Still not solved
If the error persists, stop here. See what the technician must do and show you.

What it means
Whirlpool describes SE as a problem with the keypad, which it calls the user interface, or the associated wiring. It is a control signal about the controls, not about heating. It can be a passing glitch that clears after the power cut or a keypad or wire defect that keeps coming back. The code does not separate those cases; repeating Whirlpool's procedure and seeing whether it returns does. The page is Whirlpool US's over-the-range microwave guide; confirm the code in your model's manual.
Warnings and stop conditions
- Higheditorial warning
An over-the-range microwave is not taken apart to check boards or wires: the high voltage capacitor can keep a lethal charge even with the power off. Magnetron, door seals and safety interlocks are for authorised service only.
Evidence: SE - Error Code - Over-the-Range Microwave
Symptoms and causes
Probable causes · in order
- Faulty keypadPossible
Whirlpool names the keypad as a possible origin. It fits if after the reset the code returns when pressing or a key stops responding.
Evidence: SE - Error Code - Over-the-Range Microwave
- Keypad wiringPossible
The other origin Whirlpool cites. It can only be told apart from the keypad by a technician's check, because the symptoms look the same to you.
Evidence: SE - Error Code - Over-the-Range Microwave
- Passing glitchPossible
If after the minute off and the minute of watching SE does not return and the microwave works, there is no fault left to repair.
Evidence: SE - Error Code - Over-the-Range Microwave
