Start here
Start with the water supply line and its shutoff: on a Tehanld refrigerator showing an ice maker that has stopped or slowed, that outranks everything else here, and the water inlet valve comes a long way behind it. On a compact unit the ranking is dominated by where it stands. Ask whether yours has a hand-width of air behind it and whether its hookup was made for permanent use, because both are more likely than a failed part. The first 2 checks need no tools and no panel off, and the point where owner work stops is marked below.
What you are seeing
- The cubes are fused into one block — That is air and frost rather than a water fault, and it usually means the mould has been standing too long.
- The mould is full and nothing is ejected — A full mould of good ice is a harvest problem, not a fill problem.
- NEAR MISS — the whole compartment is warm — Ice is the first casualty of a cooling fault. If food is softening too, this is not your page.
Causes, most likely first on Tehanld
- The water supply line and its shutoff — Every ice maker fault begins at the tap that feeds it, and that tap is behind the machine where it gets nudged when the unit is pulled out and pushed back. Ranked first because it is both the most likely and the fastest to settle.
- A water filter that is overdue — Restriction rather than blockage is the signature here: the machine still makes ice, but the cubes are small, misshapen or welded together, and the dispenser slows at the same time. Second on Tehanld: it gives the same picture as the cause above and is separated from it by one free test.
- Warm air reaching the compartment at the door — A seal that has taken a set, or a door held ajar by a drawer, lets humid room air onto the mould. Third on Tehanld: not rare, simply behind two checks that cost nothing.
- The water inlet valve — A valve that is weak rather than dead gives short fills, which give small cubes, which gives an owner who thinks the ice maker is failing when the real fault is upstream of the mould entirely. Ranked last, and the order matters most right here: this is the one item that changes what the repair costs.
The order to work in
- First: Trace the water line from the tap to the back of the machine — It is first because it is the cheapest check that can end the diagnosis, and it rules out the whole water path at once.
- Second: Note when the filter was last changed and try the dispenser — It comes second because a restricted filter and a part-closed tap produce the same reading and are distinguished by the same test.
- Third: Close the door on a sheet of paper and pull it out — Last in the order because a failed seal explains both the ice symptom and the frost an owner has usually already noticed.
What an owner can safely check
- Trace the supply line and open the shutoff fully — Follow the line from the tap to the machine, straighten any kink, and turn the shutoff fully open rather than part-way.
Tools: torchAbout 10 min
- Change the water filter, or bypass it if the machine allows — Fit a fresh filter, then run water through the dispenser until it flows clear and steady before judging the result.
About 15 min
- STOP HERE if the next step needs a meter on live terminals — This is where the checks above run out. What is left needs a meter, and a meter needs a technician.
Safety first
Safety
Isolate the machine at the wall or the breaker before a panel comes off. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Leave the sealed system alone — refrigerant is licensed work — and never wedge a door switch to keep a fan turning while you look.
When this becomes a service call
Stop at the first step needing a meter on live terminals, and call from there. Anything on the sealed system — refrigerant, the compressor, the tubing — is licensed work, and a machine that has been opened is a machine that needs a technician. Call sooner if the fault is getting worse rather than staying the same, because a cheap cause left alone is how an expensive one arrives.

What is deliberately not on this page
What this page does not do is speak for one family or one model. It covers Tehanld refrigerators generally, and no family-specific page exists for it yet to send you to — when one is published, this page will link down to it and defer to it. Also absent by choice: part numbers, wiring detail and dismantling order.
