How to Clean Amana Refrigerator Condenser Coils: A... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the refrigerator's temperature. When the temperature rises above a set point, the MCU energizes the compressor relay via a 12V DC signal. Restricted airflow over the condenser coils increases the time it takes to dissipate heat, leading to extended compressor run times and higher power consumption. A dirty condenser can raise the compressor discharge temperature above 150 degrees Fahrenheit.

Symptoms:

The refrigerator is not cooling properly, the compressor is running constantly, the motor is hot to the touch, and/or energy bills have increased.

Possible Causes:

Dirty condenser coils restrict airflow, reducing cooling efficiency.
Dust and debris act as insulation, trapping heat.
Insufficient airflow causes the compressor to work harder and longer.
High compressor workload can lead to overheating and premature failure.
Pet hair accumulation blocking airflow under the refrigerator.

Solution:

1

Unplug the Amana refrigerator from the 120V AC outlet.
2

Locate the condenser coils, typically at the bottom rear of the unit behind a lower access panel. Use a 1/4-inch nut driver to remove the panel.
3

Use a soft brush attachment on a vacuum cleaner to gently remove dust and debris from the coils. Be careful not to damage the fins.
4

For stubborn dirt, use a condenser coil cleaning brush, working vertically along the fins.
5

If necessary, lightly spray the coils with a commercial coil cleaner, following the product instructions. Ensure the area is well-ventilated.
6

Allow the coils to dry completely before reassembling the access panel.
7

Plug the refrigerator back into the outlet and monitor its performance.

Safety Warning:

Always disconnect the power supply before cleaning or servicing any appliance. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. The appliance contains components that operate at 120V AC. Risk of electrical shock.

Prevention:

Clean the condenser coils every 6-12 months, or more frequently if you have pets or live in a dusty environment. Use a vacuum cleaner with a brush attachment.

Expert Tip:

Some Amana refrigerators have a service mode that allows you to initiate a defrost cycle or test components. To enter service mode, simultaneously press and hold the 'Freezer Temp Down' and 'Refrigerator Temp Up' buttons for 5 seconds. Consult the service manual for specific test procedures.

Frequently Asked Questions

•How often should I clean the condenser coils on my Amana refrigerator?

Ideally, you should clean the condenser coils every 6 to 12 months. However, if you have pets, or if you live in a particularly dusty environment, you might need to clean them more frequently, perhaps every 3 to 6 months.

•What type of coil cleaner is recommended for cleaning the condenser coils?

Use a non-acidic, foaming coil cleaner specifically designed for HVAC or refrigerator coils. Ensure that the cleaner is safe for aluminum and plastic components. Follow the manufacturer's instructions carefully, and ensure the area is well-ventilated during use.

•If cleaning the coils doesn't solve the cooling problem, what else could be wrong?

If cleaning the coils doesn't improve cooling, other potential issues include a faulty start relay or overload, a failing compressor, a refrigerant leak, a malfunctioning defrost system, or a problem with the electronic control board or temperature sensor. These issues may require a qualified technician to diagnose and repair.
