Question 1

it keeps flashing the 'add water' light even though the reservoir is definitely full.

Accepted Answer

DIAGNOSIS The float switch inside the reservoir compartment is stuck or the sensor is faulty. This is the white plastic bobber on the left side. FIX Remove the water reservoir. Manually move the float up and down several times with your finger to ensure it's not stuck on its post. Also, check that the little magnet on the bottom of the float is intact and clean. IF THAT DIDN'T WORK Look inside the empty reservoir slot. There's a small magnetic reed switch on the left wall. Wipe it with a dry cotton swab to remove any dust or mineral deposits that could be interfering with the signal. HEADS UP Don't overfill the reservoir past the "Max" line. Water can splash into the float compartment and cause it to stick or give false readings.

Question 2

the full basket light comes on when the basket is only half full, so it stops making ice.

Accepted Answer

DIAGNOSIS The infrared sensor that detects ice level is either blocked or misaligned. It's located on the left side inside the ice chute. FIX Unplug the unit. Remove the ice basket. Shine a flashlight into the left side of the ice chute. You'll see a small, clear plastic lens. Wipe it clean with a dry, soft cloth—no moisture. Also clear any ice chips or dust from the corresponding sensor on the opposite side. IF THAT DIDN'T WORK The ice basket itself may not be seated perfectly flat on the base. Ensure it's pushed all the way back and sitting level. HEADS UP Stacking ice too high on the left side of the basket can prematurely trigger the sensor. Try distributing the ice more evenly.

Question 3

the ice tastes kinda plasticky or funny, even after running it a few times.

Accepted Answer

DIAGNOSIS New unit smell or taste transfer from the internal plastic components and lines. It's common and fixable. FIX Do NOT use the ice from the first several cycles. Perform the self-cleaning cycle (hold Power + Select for 3 secs), then let the unit make and discard at least 3-4 full batches of ice. Use only filtered or bottled water for this initial seasoning process. IF THAT DIDN'T WORK Check your water source. Highly chlorinated tap water or water run through a softener can impart taste. Switch to a different filtered water. HEADS UP Never add anything scented (like lemon juice) to the water reservoir to try to freshen it—it will coat the system and make the problem worse.

Question 4

how do you actually clean this thing? the manual says to clean it but the parts don't seem to come apart.

Accepted Answer

DIAGNOSIS The main user-serviceable parts for cleaning are the water reservoir, ice basket, and the interior. The internal system is cleaned via a built-in cycle. FIX For a full clean: 1) Unplug. Wash reservoir and basket with warm, soapy water. 2) Wipe interior with damp cloth. 3) Plug in, press and hold the Power and Select buttons for 3 seconds to start the 15-minute self-cleaning cycle ("CLn" will display). 4) After cycle, discard the first two batches of ice. IF THAT DIDN'T WORK If mineral scale is visible on the evaporator plate (the cold metal grid), use only Frigidaire's official ice maker cleaner (or a citric acid solution per manual) in the cleaning cycle—not vinegar, which can damage seals. HEADS UP Run the cleaning cycle every 2-4 weeks if you use it daily. Scale buildup is the #1 cause of slow ice production and weird tastes.

Question 5

it's making a loud grinding or rattling noise when it's harvesting the ice, sounds terrible.

Accepted Answer

DIAGNOSIS The ejector blades (the plastic fins that push ice into the basket) are hitting ice that hasn't fully released from the tray or a foreign object. FIX Turn the unit off and unplug it. Remove the ice basket and any loose ice. Look into the ice chute and use a plastic utensil (like a spatula handle) to gently clear any jammed ice cube or fragment from around the silver ejector blades. IF THAT DIDN'T WORK A small piece of the plastic ice basket may have broken off and fallen into the mechanism. You'll need to inspect the basket and the area beneath the ejector blades carefully. HEADS UP Never use metal tools to clear a jam—you can scratch the evaporator plate and permanently damage the unit.

Question 6

my ice is coming out super thin and hollow, like shells, and the basket is barely filling up.

Accepted Answer

DIAGNOSIS The freezing cycle is being interrupted too soon. This is usually caused by the ambient room temperature being too warm or the unit being in a draft. FIX Move the ice maker. It needs to be in a room at or below 77°F (25°C), away from direct sunlight, ovens, vents, or windows. Give it at least 5 inches of clearance on all sides for airflow. IF THAT DIDN'T WORK The unit might be in "Speed" mode (indicated by a fast-flashing light). Press the Power button once to turn it off, then press and hold the Select button for 3 seconds to switch it back to the standard ice-making cycle. HEADS UP In "Speed" mode, the ice is deliberately thinner to produce a batch faster—it's not a malfunction, just a different setting.

Question 7

the ice maker is running but it's not making any ice, just humming and the water pump sounds weird.

Accepted Answer

DIAGNOSIS The water pump is likely air-locked or the water inlet tube inside is kinked/blocked. This stops water from reaching the freezing tray. FIX Turn the unit off. Remove the water reservoir. Tilt the entire ice maker forward over a sink to drain any water from the internal tank and lines. Reinstall the reservoir, fill with fresh water, and restart. This often clears the air lock. IF THAT DIDN'T WORK Check the small silicone inlet tube that runs from the reservoir slot to the pump. Make sure it's not pinched or folded over when the reservoir is inserted. HEADS UP Always use the unit on a hard, level surface. On a soft or uneven counter, the internal alignment can shift, kinking that tube.

Question 8

my frigidaire countertop ice maker just arrived and it won't turn on at all, no lights, nothing.

Accepted Answer

DIAGNOSIS This is almost always a power supply or unit assembly issue. The unit isn't getting power or a crucial internal connection isn't made. FIX First, check the power cord is fully plugged into the BACK of the unit, not just the wall outlet. This cord is detachable and can look seated but not be clicked in. Push firmly until you hear/feel a click. IF THAT DIDN'T WORK Ensure the water reservoir is correctly installed. It must be pushed all the way in until it clicks and the float moves freely. An unseated reservoir can prevent the unit from powering up. HEADS UP Don't run the unit without the reservoir properly clicked in—it can cause water to leak into the electronics.
