Maytag Refrigerator Making Noise

Common Symptoms

• Loud humming or buzzing from inside the freezer compartment
• Rattling or vibrating noise when the refrigerator runs
• Grinding or squealing sound that gets louder over time

Most Likely Causes

1. 1

   Evaporator Fan Blade Ice Obstruction — Most Common

   The evaporator fan circulates cold air from the evaporator coil throughout both the freezer and refrigerator compartments. When frost or ice builds up on the evaporator coil and fan blade, the blade makes contact with the ice, producing a loud buzzing or chirping sound that increases when the freezer door is opened. This is the single most common cause of noise in Maytag refrigerators and indicates a defrost system issue. Manually defrosting the unit (unplugging for 24 hours) resolves the noise immediately — if it returns within a week, a defrost heater, thermostat, or control board failure is the root cause.

2. 2

   Condenser Fan Blade Debris or Bearing Failure

   The condenser fan is located at the rear bottom of the refrigerator and draws air across the condenser coils to dissipate heat. Lint, pet hair, and debris can accumulate on the fan blade, causing an imbalanced, rattling rotation. A worn fan motor bearing produces a continuous grinding or scraping sound that occurs whenever the compressor is running. The condenser fan compartment should be cleaned every 6–12 months — heavy debris buildup also causes the compressor to run hotter than designed.

3. 3

   Evaporator Fan Motor WPW10189703 Bearing Failure

   The evaporator fan motor (WPW10189703 on many Maytag models) contains sleeve bearings that wear over time. A failing motor bearing produces a squealing or grinding noise from the freezer compartment that is loudest when the door is closed and may quiet or change pitch when the door is opened (because opening the door triggers a door switch that stops the fan on most models). Test the motor by manually spinning the fan blade with the refrigerator unplugged — a good bearing spins freely and smoothly; a worn bearing feels rough or catches.

4. 4

   Compressor Vibration and Worn Mounts

   The compressor is the heart of the refrigerant system and produces a low, steady hum during normal operation. A compressor that hums louder than usual, makes a clicking noise when starting, or vibrates excessively may have worn rubber isolation mounts or be mechanically failing. Worn compressor mounts cause the compressor body to transfer vibration directly to the cabinet, producing a buzzing or rattling that can be felt when touching the sides of the refrigerator. Start relay failure causes rapid clicking as the compressor attempts to start repeatedly.

5. 5

   Ice Maker Fill Cycle Noise

   The ice maker produces several normal sounds: a hissing or gurgling as water flows through the inlet valve, a loud cracking or popping when ice cubes are ejected, and a thump when the ice falls into the bin. These sounds occur every 90–180 minutes during normal ice production and are not a defect. Abnormal ice maker sounds include: a continuous water hammer banging in the supply line when the valve closes, a grinding if ice cubes are jammed in the ejector mechanism, or a buzzing if the inlet valve solenoid is buzzing due to low water pressure (below 20 PSI).

6. 6

   Drain Pan Rattle

   The plastic drain pan under the refrigerator sits on support rails and can vibrate against the cabinet when the compressor and condenser fan run. This produces a low-frequency rattle or buzzing that seems to come from beneath the unit. The drain pan rattle is louder on hard floors. Removing and reseating the drain pan, or placing a folded paper towel under one edge to dampen vibration, typically eliminates this noise.

7. 7

   Water Hammer in Supply Line

   When the water inlet valve closes at the end of an ice maker fill cycle, the abrupt water stop can cause a loud banging or hammering sound in the household supply line — this is called water hammer. The sound comes from the wall or the supply line behind the refrigerator, not from the refrigerator itself. Installing a water hammer arrestor on the supply line (approximately $10–$15) eliminates this noise permanently. Water hammer is more common with high household water pressure (above 60 PSI).

Quick DIY Checks

1. 1Identify the noise location: open the refrigerator doors and listen to determine whether the sound comes from the freezer interior (evaporator fan), the bottom rear of the unit (condenser fan or compressor), or beneath the unit (drain pan). Have someone listen while you open and close the freezer door — if the noise changes immediately when the door opens, the evaporator fan is the source (the door switch stops the fan when the door is open on most models). If the noise comes from below and occurs whenever the compressor runs, proceed to the condenser area.
2. 2Check for evaporator fan ice obstruction: unplug the refrigerator. Remove the freezer back interior panel (3–5 Phillips screws plus any wire clips). Inspect the evaporator coil and fan blade — if you see a solid block of ice surrounding the coil or touching the fan blade, the defrost system has failed. Note the ice thickness: light frost is normal, but a 1–2 inch solid ice block means the heater, thermostat, or control board has failed. Defrost the unit manually by unplugging for 24–48 hours with the freezer door propped open and towels on the floor. If the noise returns within a week, follow the maytag-refrigerator-not-defrosting guide.
3. 3Test the evaporator fan motor WPW10189703: with the refrigerator unplugged and the evaporator back panel removed, manually spin the fan blade. A good bearing spins freely, smoothly, and coasts to a stop — a failing bearing feels gritty, catches, or stops abruptly. Reconnect power (carefully — the coil is exposed) and observe the fan running: it should spin steadily without wobble. Press and hold the freezer door switch to activate the fan while the door is open. A squealing or grinding motor that passes the spin test may have a weak winding — test motor resistance: disconnect the harness and check between the motor leads; resistance should be 200–400 ohms, OL indicates an open winding. Replace WPW10189703 if bearings are rough or winding is open (approximately $25–$45).

1. 4Clean the condenser fan and coils: unplug the refrigerator and pull it away from the wall. Remove the rear access panel (4–6 screws). Locate the condenser fan at the lower rear — remove any debris from the blade with a vacuum crevice attachment. Spin the blade by hand: it should rotate freely and smoothly. Check the condenser coil directly behind the fan — a lint-clogged coil will be visibly packed with debris. Use a refrigerator condenser coil brush to loosen debris from between the fins, then vacuum. Clean coils reduce compressor noise and improve efficiency. While the panel is off, check that the condenser fan motor wiring harness is not resting against any metal — contact noise can mimic a bearing rattle.
2. 5Inspect the drain pan for rattling: with the refrigerator pulled out, remove the base grille (snaps off or 2 screws) and pull out the drain pan. Inspect the pan and its support rails for debris or positioning issues. Reseat the pan firmly on both rails. If the pan is clean and still rattles, place a folded paper towel under the center of the pan as a damper. Check that no supply line or wiring is resting on the pan — contact with a vibrating component causes sympathetic rattling.
3. 6Diagnose compressor noise and mounts: with the refrigerator running, press your hand flat against the side of the unit — a normal compressor hum is barely felt. Excessive vibration felt through the cabinet suggests worn rubber isolation mounts on the compressor feet. Shine a flashlight at the compressor (bottom rear) and look for cracks or deterioration in the rubber grommets at the compressor mounting bolts. Replacing isolation mounts is a moderately advanced repair — if the compressor itself is making a loud grinding, knocking, or continuous rapid clicking sound, the compressor may be mechanically failing and a professional diagnosis is warranted.
4. 7Check for ice maker abnormal noise: observe the ice maker through a full fill cycle. Normal sounds include: a hissing as the inlet valve opens (2–3 seconds), a pause while the tray fills, a click as the valve closes. If you hear a banging in the wall supply line when the valve closes, the water pressure is high — install a water hammer arrestor (approximately $10–$15) on the supply line behind the refrigerator. If you hear a grinding from the ice maker itself, unplug the refrigerator and check the ejector arm for jammed ice cubes. A buzzing inlet valve during fill typically indicates low water pressure — the solenoid buzzes when it cannot fully open against low flow. Minimum water pressure for the ice maker is 20 PSI.
5. 8Test the start relay if you hear rapid clicking: the start relay is a small plug-in component on the side of the compressor (accessed from the rear lower panel). Unplug the refrigerator, remove the relay, and shake it — a loose or rattling pellet inside the relay indicates relay failure. Test the relay with a multimeter in ohms mode between the run and start terminals: 3–20 ohms = good; OL = failed. A failed relay causes the compressor to click rapidly as it tries and fails to start. Replace the start relay (part varies by model — search by model number, approximately $10–$25) — it is a plug-and-play repair requiring no tools.
