Frigidaire Refrigerator MRT21GNBD1 Won't start or doesn't start

The Compressor Run Capacitor is an OEM replacement part for Frigidaire refrigerators. This electrical component is essential for providing the necessary torque to start and maintain the operation of the compressor motor, which is responsible for cooling the refrigerator.

Symptoms of a failing compressor run capacitor include:

• The refrigerator not running or cooling properly
• The compressor failing to start or running intermittently
• Humming or buzzing noises coming from the compressor area

Causes of needing to replace the compressor run capacitor can include normal wear over time, exposure to high temperatures or electrical surges, or physical damage to the capacitor itself.

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore refrigerator models. 

The Defrost Timer is an OEM part for Frigidaire refrigerators. It is an essential electronic component that controls the automated defrost cycle of the refrigerator. The defrost timer monitors run times and temperatures to determine when to initiate the defrost process. It allows the refrigerator to operate efficiently by preventing excessive ice buildup. This defrost timer is designed to run for 30 minutes every 8 hours. 

Symptoms of a bad defrost timer include: 

• Inability to initiate or maintain the defrost cycle 
• Excessive ice buildup in the freezer compartment
• Erratic temperature fluctuations
• The refrigerator running excessively or displaying other performance issues

Causes of a bad defrost timer can be normal wear and tear over time. Environmental factors like power surges or fluctuations may also impact the electronic timer functionality. 

This OEM Frigidaire part can also be used on Electrolux, Frigidaire, Gibson, Kelvinator, Westinghouse, and Sears/Kenmore.
