Crosley Refrigerator CS21A5DA Won't start or doesn't start

The Run Capacitor is an OEM part for Whirlpool refrigerators. It is responsible for helping the compressor motor start and run efficiently by providing an extra electrical boost. This component ensures that the refrigerator operates smoothly and maintains the correct temperature by stabilizing the compressor's performance.

Causes of a bad run capacitor can include electrical surges, age-related wear, or overheating. When the capacitor fails, the compressor may struggle to start or run continuously, leading to inefficient cooling or a non-functional refrigerator.

Symptoms of a bad run capacitor include:

• The refrigerator not cooling properly
• The compressor not starting or running intermittently
• Unusual clicking noises from the refrigerator

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

This thermal overload protector helps prevent motor overheating by interrupting power when temperatures exceed safe limits. It restores normal operation once the motor cools, protecting the appliance from damage and reducing risk of failure. What it does:

• Senses excessive motor temperature and interrupts current to stop the motor from running when overheated
• Helps prevent motor burnout and related electrical damage
• Can resolve symptoms such as a dryer or washer motor that stops mid-cycle, won't start, or trips the circuit during heavy use
• Works as a safety device in the motor circuit rather than a control or relay

• One thermal overload protector

• Disconnect power before accessing or replacing the motor overload; follow appliance-specific service manual steps
• Handle terminals and wiring carefully; replace using the same connections and orientation as the original
• If the motor repeatedly overheats after replacement, inspect motor bearings, venting, or other causes rather than replacing overload repeatedly

This PTC start relay mounts on the compressor and briefly powers its start winding to get it running, then drops out. Replacing a weak relay can restore reliable starts and resolve clicking/humming with no cooling.

• Provides the initial boost to the compressor via a positive temperature coefficient (PTC) element, then opens as it heats
• Takes the start winding out of the circuit once the compressor is running
• Typical failure symptoms: compressor won't start, repeated clicking/humming, no cooling, visible heat damage at the relay or connector
• Direct replacement for the original PTC start device used on applicable models

• Disconnect power before servicing; allow hot components to cool
• Access the compressor compartment, remove the cover, and note the relay's orientation; pull the old relay straight off the compressor pins
• Inspect wiring terminals for heat damage; do not reuse burnt connectors
• Firmly seat the new relay on the compressor terminals, reinstall the cover, restore power, and verify compressor start
