The short answer
A Maytag freezer ice maker that has stopped is a water-path problem before it is an ice-maker problem. Work along the path in order: the shut-off arm, the supply valve, the filter, the fill tube and only then the ice maker itself. Most no-ice calls end at one of the first three, and each of them is visible without a meter.
Causes, ranked for this Maytag freezer
- Shut-off arm raised or the ice maker switched off — Why: The arm is knocked upward by a bag or a hand reaching past it and the machine then correctly makes nothing, which is why it must be ruled out before anything else.
- Water filter overdue or restricting flow — Why: A filter past its life reduces flow enough that the fill is short or freezes in the tube, and it produces small hollow cubes long before it produces none.
- Supply valve closed, kinked or the inlet valve weak — Why: A saddle valve or stop behind the unit is easily closed during other work and never reopened, and a weak inlet valve fills too slowly to complete a cycle.
- Frozen fill tube — Why: A short or slow fill leaves water standing in the tube, which freezes and blocks every subsequent fill, so the fault compounds itself until the tube is thawed.
- Ice maker module, mould heater or thermostat — Why: Last, because everything above imitates it and costs far less; a tray with a solid slab of ice, rather than a dry tray, is what actually points here.
What to check, in order
- look at the shut-off arm and confirm it is in its lowered, running position. — Because: it is the cheapest possible answer and it is knocked upward constantly.
- note whether the tray is dry or holds ice. — Because: a dry tray is a water-supply diagnosis and a full frozen tray is a harvest diagnosis, and they share no parts.
- check the age of the water filter and the position of the supply stop behind the unit. — Because: both are common, both are owner-correctable, and both starve the fill.
- look for a plug of ice in the fill tube at the rear of the compartment. — Because: a frozen tube blocks every fill afterwards, so it must be cleared before any other test means anything.
Checks you can safely do yourself
- Check that the shut-off arm is lowered and that any ice-maker switch is on, then wait for a fill cycle before concluding anything. — Tools: none — Time: several minutes
- Look into the ice tray and note whether it is dry, holds water, or holds a solid slab of ice. — Tools: a torch — Time: a minute
- Check when the water filter was last changed and replace it if it is overdue, then run several litres through the dispenser to clear air. — Tools: a replacement filter — Time: several minutes
- Trace the supply line behind the unit and confirm the stop valve is fully open and the line is not kinked where the unit was pushed back. — Tools: a torch — Time: several minutes
- Look at the fill tube entering the ice maker for a plug of ice, and thaw it with a warm damp cloth rather than any tool. Stop here: the module, mould heater and inlet valve need a meter. — Tools: a warm damp cloth — Time: the better part of an hour
Before you open anything
Safety
unplug-before-service freezer-0f
Unplug the unit before reaching behind the ice maker or removing a panel, and never use a knife, screwdriver or hot metal to clear ice, since the fill tube and evaporator tubing behind it puncture easily. Do not pour hot water into the ice maker to thaw it; use a warm damp cloth and let it work.
Where the owner fix ends
Lowering the arm, changing the filter, opening the supply stop and thawing the fill tube are owner work. Call a technician when the tray fills with water and never harvests, since that is the module, mould heater or thermostat; when the fill tube refreezes after being thawed, which means the fill is short rather than blocked; and when the compartment is above the safe holding temperature quoted above, because ice production needs the compartment cold first.
