Whirlpool Microwave F2 Error — Keypad Fix

What Does This Error Mean?

F2 on a Whirlpool microwave means the touchpad is reporting a stuck button or short. Unplug for 5 minutes to reset. If F2 returns, allow 24 hours unplugged with the door open to dry — persistent F2 means the touchpad needs replacement.

Affected Models

Whirlpool WMH31017HS
Whirlpool WMC30516HZ
Whirlpool WMH53521HV
Whirlpool WMH73521CS
Whirlpool WMH76719CS

Common Causes

A keypad button physically stuck by debris or grease
Moisture from cooking steam reaching the keypad ribbon
Worn keypad membrane (common in microwaves over 8 years old)
Damaged ribbon cable between touchpad and main control board

How to Fix It

Unplug the microwave for 5 minutes.

Disconnect power at the wall — over-the-range models may need to be slid down to access the plug. After 5 minutes, restore power and check if F2 has cleared.
Clean the keypad surface.

Wipe the keypad gently with a barely damp cloth to remove any grease, food, or dried liquid. Do not spray cleaner directly on the keypad — moisture is a common cause of F2.
Test each button for sticking.

Press every button in sequence and listen for the beep. A button that does not beep, or beeps continuously, is the stuck one.
Dry the microwave for 24 hours if needed.

If F2 follows a steam-heavy cooking session or a clean of the microwave, leaving it unplugged with the door ajar for 24 hours often allows trapped moisture to evaporate from the keypad.

Frequently Asked Questions

How much does it cost to replace a Whirlpool microwave touchpad?

Whirlpool touchpad assemblies cost roughly USD 80–150 for the part, plus USD 100–150 for labour. For microwaves over 8 years old, replacement is often more economical than repair.

Will F2 fix itself eventually?

F2 from temporary moisture often clears after a 24-hour dry-out. F2 from a worn keypad membrane or stuck button will not self-resolve and gets progressively worse over time.
