Amana Refrigerator TRI21VW 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 PTC start relay plugs onto the compressor to momentarily power the start winding and help the compressor spin up smoothly. Replacing a failed relay can stop repetitive clicking and help restore stable cooling performance. What it does:

• Momentarily energizes the compressor's start winding at startup; the PTC element then increases resistance to take the start winding out of the circuit.
• Helps protect against repeated hard-start attempts that cause clicking and no-cool conditions.
• Common failure signs include repeated clicking, the compressor not starting, warm temperatures, burn marks/melted housing, or a relay that rattles when shaken.
• Mounts directly on the compressor terminals and interfaces with the model-specific overload and cover.

• 1 PTC start relay

• Disconnect power and allow components to cool before servicing.
• Access the compressor compartment; remove any cover/retainer to reach the start device.
• Note wiring and orientation; pull the old relay straight off the compressor pins and push the new relay fully onto the pins. Reconnect wires and reinstall the cover.
• Use only the start device specified for your exact model/compressor. If the old relay shows heat damage, inspect the matching overload and wiring for issues.

This defrost timer assembly cycles the refrigerator between cooling and defrost modes to prevent excess frost buildup and help maintain consistent temperatures. Replace a failed timer to restore regular defrost scheduling and reduce icing. What it does:

• Advances the refrigerator between cooling and defrost cycles on a timed schedule.
• Stops missed defrosts that can cause frost buildup on the evaporator and reduced cooling efficiency.
• Addresses symptoms such as excessive frost/ice, inconsistent temperatures, or a freezer that runs constantly.
• Acts as the control that engages the defrost heater and returns the unit to cooling when the cycle finishes.

• Disconnect power to the appliance before servicing to avoid shock or injury.
• Access the timer via the control panel or rear service area; document wiring or take photos before disconnecting.
• Install the timer in the same orientation and reconnect wires to the original terminals; do not force connectors.
