Oven Convection Fan Not Working? 6 Causes and What to Do
A convection fan that will not spin is usually a failed fan motor, a seized blade, a door switch or a relay on the control board. Here is how to narrow it down.

Why is my ice maker not making ice?
An ice maker usually stops because the water supply is blocked, the freezer is not cold enough, the ice maker is switched off, or a part has failed. The most common failed parts are the water inlet valve, the ice maker assembly, and a frozen fill tube.
Most of these checks take less than 10 minutes. Start with the simple ones before you assume a part is broken.
What should you check first?
- Is the ice maker turned on? Look for a switch, a wire arm that is raised, or an ice setting on the display.
- Is the freezer cold enough? Most ice makers need the freezer near 0°F. Above about 10°F, ice production slows or stops.
- Is the water filter old? A clogged filter cuts water flow. Most makers suggest a new filter about every six months.
- Does the water dispenser work? If the dispenser is also slow or dry, the problem is likely the water supply, filter, or inlet valve.
- Is ice jammed in the bin or chute? Clumps can block the ice maker from dumping or sensing a full bin.
What are the most common causes?
A clogged water filter
Filters trap sediment and minerals. When they clog, the ice maker gets too little water and makes small cubes or none at all. Use a filter made for your model. NSF's water filter FAQ advises changing filters on the schedule the manufacturer gives.
A frozen fill tube
The fill tube carries water into the ice mold. If water pressure is low or the freezer is very cold, water can freeze inside the tube and block it. A technician can thaw it and find out why it froze.
A failed water inlet valve
This valve opens to let water into the ice maker and dispenser. If it fails, neither gets water. It is one of the most common ice maker repairs.
A failed ice maker assembly
The assembly has a small motor, a heater that releases the cubes, and a control. If the freezer is cold and water reaches it, but no ice is made, the assembly may need replacing.
Low household water pressure
Ice makers need a minimum water pressure to fill properly. If other taps in the house are weak, the pressure may be the problem, not the fridge.
Does Mountain View's water affect ice makers?
Most Mountain View homes get soft water, so heavy mineral buildup is less common than in many areas. Homes on the harder Valley Water supply may see more scale in valves and filters over time.
The City explains where your water comes from and how hard it is on its water FAQ page.
Ice maker still empty after these checks? Call us and a technician can test the valve, fill tube, and assembly.
When should you call a technician?
Call if the freezer is cold and the filter is new but you still get no ice, if the dispenser and ice maker both stopped, or if you see water leaking under the fridge. Our ice maker repair service fixes built-in and freezer ice makers from Sub-Zero, Samsung, LG, Whirlpool, GE, and more. You can see typical prices in our repair cost table.
Some ice makers have been recalled for safety issues, so it is worth checking the CPSC recall list for your model. If water is pooling under your fridge, read our guide on refrigerator leaks.
Frequently asked questions
How long does a new ice maker take to make ice?
Most refrigerator ice makers need about 24 hours after installation or a reset to make the first full batch. It can take up to three days to fill the bin.
Why are my ice cubes small or hollow?
Small or hollow cubes usually mean low water flow. A clogged water filter, low house water pressure, or a partly frozen fill tube are the most common causes.
Is a broken ice maker worth repairing?
Usually, yes. Water inlet valves, fill tubes, and ice maker assemblies are common, affordable repairs, especially compared with replacing a refrigerator.
