Frigidaire Refrigerator MRT15CNEYB 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.

This compressor start device kit helps your refrigerator or freezer's compressor start reliably each cooling cycle. Replacing a weak or failed start device can restore cooling performance and stop repetitive clicking or brief humming when the compressor tries to start.

• Powers the compressor's start winding to initiate start-up, then disengages
• Supports consistent compressor starts to maintain proper temperatures
• Common symptoms of failure: unit warm, compressor not running, rapid clicking from rear, humming then shuts off
• May accompany signs like heat damage or a burnt odor at the old device

• Unplug the appliance before servicing; allow components to cool
• Located on the side of the compressor behind the rear access panel
• Photograph wiring and compressor pin layout; transfer wires one at a time and seat the device fully on the pins
• If your unit uses a separate run capacitor, reconnect it exactly as originally wired
