Whirlpool (and the Maytag, KitchenAid, and Amana fridges built on the same platforms) use a reliable icemaker, so when it stops there's usually a specific, fixable cause. Here's the order a tech checks them, plus the simple things you can rule out yourself first.
Whirlpool recommends a new water filter about every 6 months. A clogged filter is the most common reason ice slows to a trickle or stops.
Check it: Swap the filter, dispense water a few times to clear air, and wait 24 hours for a fresh batch.
If the wire shutoff arm is lifted (or the paddle feeler is stuck), the icemaker thinks the bin is full and stops. Clumped ice can also jam the bucket.
Check it: Make sure the metal arm is down (the ON position), break up any clumped ice, and reseat the bin fully.
Many Whirlpool fridges use an infrared emitter and receiver to sense the ice level. If those windows are dirty or one has failed, the icemaker reads "full" and won't make ice.
Check it: Wipe the two small sensor windows on the freezer walls clean. If cleaning doesn't help, the emitter/receiver is a tech replacement.
The icemaker needs the freezer near 0°F to cycle. A warm freezer, blocked vents, or a weak door seal slows ice way down.
Check it: Set the freezer to 0°F, keep food off the vents, and confirm the door seals.
The icemaker motor/module or the water inlet valve that fills the mold can fail, and no reset will bring it back.
Check it: This is the tech diagnosis — we confirm whether it's the module, the valve, or the optics and replace the right part.
Repair — icemaker modules, optics sensors, and inlet valves are all affordable Whirlpool parts and a straightforward fix. Replacing the fridge over an ice maker almost never makes sense.

Most often an overdue water filter, a lifted shutoff arm, or a blocked optics sensor telling it the bin is full. Change the filter, put the arm down, wipe the sensor windows — that clears the majority of cases.
It's the wire arm on the side of the icemaker — down is ON, up is OFF. Some newer models use a paddle feeler or a switch instead; if the arm is down and it still won't make ice, check the filter and optics next.
Often it's just a filter or a free reset; a module or inlet-valve replacement is an affordable part plus flat labor. Your $50 Quick Check credits toward the repair.
