Step-by-step
Diagnose it yourself in 5 minutes
Free checks first, then paid parts. Most owners identify the failed part by step 4.
- 1Confirm the on/off arm or toggle is in the ON positionOlder Whirlpool / KitchenAid / GE — the wire bail arm has to point DOWN. Newer Samsung / LG / Frigidaire — check the panel toggle. This is the #1 free fix and about 10% of the calls we take.
- 2Check the water filter ageIf the filter is more than 6 months old (or the FILTER indicator light is red), swap it. A clogged filter starves the inlet valve of the ~30 PSI it needs to open. Buy the OEM filter for your model, not the aftermarket variant.
- 3Test water flow at the dispenserPress the water dispenser for 10 seconds. Full stream = supply water is fine, problem is in the ice maker. Trickle or nothing = supply-line, filter, or inlet-valve problem.
- 4Look for a frozen fill tubePull the ice bin out. The fill tube is the plastic tube coming down from the top-back of the freezer wall. Ball of ice at the end = frozen fill tube — thaw with a hair dryer, and the fault is either low pressure or a failed fill-tube heater.
- 5Force a harvest cycleMany ice makers have a small test port on the module. Bridging T and H terminals with a paper clip forces a harvest. If the fingers turn and water fills — module and valve are fine, fault is elsewhere. If nothing happens — module is bad.
Samsung RF28 / RF23 / RF26 and some LG French-door units have known ice-bucket freeze-up issues tied to door seal and defrost calibration — not a generic module failure. If your bucket is a solid block of ice, ask the tech about the brand-specific service bulletin fix instead of paying for a module swap that won't hold.
Repair vs. replace
Fix the ice maker or fix the fridge?
- Fridge is under 12 years old and cooling normally
- Fault is filter, fill tube, inlet valve, or module
- Repair cost is under $500 (typical case)
- Fridge itself is failing (compressor, sealed system)
- Unit is 15+ years old with cabinet or door-seal degradation
- Third ice-maker failure on the same fridge in 3 years

FAQ
Ice maker not making ice — full FAQ
Why is my ice maker not making ice?
About 80% of the time it's one of three parts: a frozen fill tube (low water pressure or bad tube heater), a failed water inlet valve at the back of the fridge, or a failed ice maker module. The other 20% is a clogged water filter, a stuck on/off arm, or a broken supply line. A real diagnostic — not a parts-cannon — identifies which within 15 minutes.
Should I check the water filter first?
Yes — always. It's the cheapest thing to swap and it's the failure point about 15% of the time. If your filter is more than 6 months old, the FILTER indicator light is red, or the water dispenser flow has slowed at the same time as the ice-maker failure, replace the filter first and give it 24 hours to make ice before spending anything else.
How long should a new fridge take to start making ice?
12–24 hours after installation for the first tray of ice, and typically 3–5 days to build a full bin. Modern French-door units make about 2–3 lbs of ice per day at factory settings. If it's been 48+ hours with a new install and there's still no ice, check the water line was fully connected and the ice-maker toggle is on.
My Samsung / LG ice maker keeps freezing up. Is that different?
Yes — Samsung French-door ice makers (RF28, RF23, RF26 series) have a documented ice-bucket freeze-up problem tied to the door seal and defrost calibration. LG French-door ice makers can have a similar issue on some model years. If your bucket is a solid block of ice and manual harvest doesn't help, that needs the brand-specific service bulletin fix — not a generic module swap.
Can I fix an ice maker myself?
Filter swap and on/off arm — absolutely. Frozen fill tube thaw — yes, with a hair dryer. Inlet-valve replacement — moderate DIY, 45–90 minutes, needs the correct valve for your model. Ice-maker module — moderate DIY on Whirlpool / KitchenAid, harder on Samsung / LG which use a full assembly. Most people call once it's clear the module or valve is bad.
How much does ice-maker repair cost in the Twin Cities?
Water filter: $65 (DIY) or $145 installed. Water inlet valve: $245–$365 all-in. Ice-maker module or assembly: $285–$465. Full ice-maker head unit (French-door built-in): $385–$525. All prices include the $149 trip fee (waived on approval) and 1-year written parts-and-labor warranty.
How long does an ice maker last?
6–10 years for the module, 10–15 years for the water inlet valve, and roughly the life of the fridge for the fill tube and heater. Samsung and LG French-door ice makers historically fail sooner (4–6 years) than Whirlpool, KitchenAid, and GE (8–12 years). Sub-Zero built-in ice makers are typically 10+ years.
How fast can you get here?
Same-day windows are typically available across the Twin Cities on weekday calls before 2pm (before 1pm for outer-ring suburbs). Book online for your ZIP's exact next-available window. Common ice-maker parts for Whirlpool, KitchenAid, GE, Samsung, LG, and Frigidaire ride on the truck.
