Is your Amana refrigerator not playing it cool? A warm fridge can be a real headache, but hold off on calling that technician just yet. Most often, the issue lies in something as simple as ice buildup or dirty condenser coils, both of which you can easily tackle yourself. However, it can also be due to some failed components like a dormant compressor or a lazy evaporator fan. Whether it’s a minor hitch or something more serious, I’ll guide you through diagnosing and potentially fixing the problem.
Reasons Why Amana Refrigerator Not Cooling
1. Refrigerator is not turned on:
You might chuckle, but this is more common than you’d think. People often overlook the most fundamental step—ensuring the appliance is powered on. It’s especially common after power outages, moves, or when setting up a new unit. Before diving into more complex diagnostics, always check if your refrigerator is on.
2. Power Supply Issue:
Electricity is the lifeblood of your refrigerator, and without it, your fridge remains inactive. A blown fuse, a tripped circuit breaker, or a faulty outlet could disrupt the power supply. Periodically ensure the power cord is plugged in securely and that the outlet is functioning. Using a multimeter can help ascertain if power is reaching your refrigerator. If you’re unsure, try plugging another appliance into the same outlet to see if it works.
3. Controls are off or set incorrectly:
Every refrigerator has temperature controls that dictate how cold the unit should be. Sometimes, these settings can get unintentionally changed maybe during cleaning or when items shift and bump against them. If the refrigerator’s controls are turned off or set to a warmer temperature, your fridge won’t cool as expected. Periodically review your temperature settings to ensure they are optimal.
4. Refrigerator is next to a heat source:
Placing a refrigerator next to a heat source, like an oven, a heater, or in direct sunlight, can dramatically impact its efficiency. The added external heat makes the refrigerator work harder to maintain its internal temperature, which can lead to cooling inefficiencies or even long-term damage. Ensure your refrigerator is positioned in a cool, shaded spot and has adequate ventilation around it. If you’re limited on placement options, consider using a barrier or insulator between the refrigerator and the heat source.
What To Do If Your Amana Refrigerator Stops Cooling?
1. Check The Thermostat:
This isn’t just a dial; it’s the device determining the internal temperature of your refrigerator. If it’s faulty, the fridge may not cool at all. Ensure it’s turned on and set to the desired cooling level. If the temperature inside doesn’t match the setting, the thermostat might be the culprit. To replace the thermostat carefully remove the wires from the old thermostat. Install the new thermostat accurately. Once the thermostat is securely in place, reattach all covers and panels. Ensure everything clicks or fits snugly into its respective position.
2. Clean The Condenser Coils:
These coils, located at the back or beneath the unit, release heat from the refrigerator. Over time, they attract dust and grime, which hampers their efficiency. Regularly cleaning these coils ensures the fridge can dissipate heat effectively, thereby cooling the interiors efficiently.
3. Check The Door Seals:
Your refrigerator’s door seals are its gatekeepers, keeping the cold air in and the room-temperature air out. If they’re worn out or dirty, they might not be sealing as effectively. Inspect them for any cracks, gaps, or debris and clean them with a mild detergent to ensure a tight seal.
4. Check The Condenser Fan:
This fan is responsible for keeping the condenser coils cool. If it’s obstructed or not working, the coils won’t dissipate heat effectively. Make sure it’s free of obstructions and rotates smoothly.
Replacing the condenser fan:
Tools Needed:
- 5/16 and 1/4 inch ratcheting wrenches
- Wire strippers
- A drill or nut drivers
Steps to Replace the Condenser Fan:
Step 1: Remove the Fan Blade: There is a clip holding the fan blade in place. Remove this clip to pull the fan off.
Step 2: Unscrew the Old Fan: On the back, you’ll find three 1/4-inch screws. These should be located in three spots around the fan. Remove these screws.
Step 3: Cut the Wires: Prepare the fan for replacement by cutting the wires, ensuring you can splice in the new fan.
Step 4: Pre-thread the Screws: Before installing the new fan, pre-thread the screws. This technique, using self-tapping screws, makes it easier to fix them in place during assembly.
Step 5: Connect the Wires: Connect the wires of the new fan. Note that the new fan has a ground wire, which should be attached to the chassis when one of the screws is being secured.
Step 6: Attach the Rubber Isolator: This helps stabilize the fan.
Step 7: Reattach the Fan Blade: Using the provided nut or screw, securely place the fan blade back onto the motor.
Step 8: Reassemble the Back Panel: Ensure all parts are secured and in their proper places.
5. Check the evaporator fan:
Found in the freezer compartment, this fan circulates the cold air throughout the refrigerator. If it’s malfunctioning, you’ll likely notice irregular temperatures. Like the condenser fan, ensure it spins freely and isn’t obstructed.
6. Check The Compressor And Start Device:
Consider the compressor as the refrigerator’s engine. It compresses the refrigerant and circulates it through the coils. If it’s not working, you might not hear the familiar humming sound. If it’s silent or making strange noises, it might be time for a repair or replacement.
Replacing the start device on the compressor:
Tools Needed:
- Multimeter
- Needlenose pliers
- Quarter-inch nut driver or a quarter-inch drill bit incorporated with a drill
Repair Steps:
Step 1: Power supply: Disconnect the power supply.
Step 2: Voltage: Verify that the outlet provides the correct voltage.
Step 3: Access the Compressor: Remove the back panel to reveal the compressor and its starting components: the run capacitor, start relay, and overload.
Step 4: Remove the Start Device: The start device is held in place by a spring clip. Using the needlenose pliers, flex the spring clip out of its position towards the compressor and lift. Gently remove the start device from its three-pronged attachment to the compressor. Disconnect the two wires attached.
Step 4: Diagnosis Confirmation: Shake the start device. If it produces noise, it’s faulty and needs replacement.
Step 5: Test the Compressor: Using the multimeter, measure the resistance (ohms) across the three windings of the compressor. The two smaller windings should add up to the value of the greater winding. Check for grounding issues by setting the multimeter to continuity mode and measuring each winding against the copper lines.
Step 6: Replace the Start Device: Match the old start device with the new one. Reconnect the wires, ensuring they are securely connected. Align the new start device with the compressor and push it in place. Reattach the spring clip to secure the start device.
Step 7: Reassemble the Back Panels: Reinstall the smaller back panel that would cover the water inlet valve if there was an icemaker installed. Attach it using quarter-inch screws. Then, install the larger unit cover that protects the condenser fan motor and the compressor. Align it properly, ensuring all screws fit into their designated holes. Secure it in place using quarter-inch screws.
7. Check The Power:
Always ensure your refrigerator is plugged in and receiving power. It might sound basic, but power interruptions can be the reason behind a suddenly warm fridge.
8. Check For Clogs:
Air vents inside the refrigerator ensure proper airflow. If they’re blocked by food items or ice, it can lead to uneven cooling. Regularly check and clear any obstructions.
9. Check the start capacitor:
Working in tandem with the start relay gives an extra boost to the compressor during startup. If it’s faulty, the compressor may struggle to kickstart.
10. Replace the main control board:
Think of this as the refrigerator’s CPU. It manages most of its functions. While it’s rare, if this board malfunctions, it might affect the cooling efficiency.
11. Damper Control Assembly:
This component regulates how much cold air is moved from the freezer to the refrigerator compartment. If it’s not opening or closing properly, it could lead to temperature discrepancies between the two sections.
