Start Capacitor Parts

Compressor won't start or cycles on and off? This overload protector prevents motor damage by cutting power during overheating. DIY-friendly fix.

Motor won't start or keeps shutting off? This refrigerator overload protector stops the motor when it overheats, preventing damage and unsafe operation.

This microwave high-voltage capacitor replaces the internal capacitor that stores and supplies the pulse of energy needed for the magnetron to generate microwaves. Restores proper HV circuit operation when the capacitor is faulty. What it does:

• Stores and releases high-voltage energy used by the microwave's magnetron
• Commonly fails after electrical stress, age, or arcing
• Symptoms of a failing capacitor: microwave not heating, intermittent operation, humming or arcing noises, or blown fuses
• Works with the high-voltage circuitry—do not use as a general-purpose capacitor

• Disconnect power and unplug the appliance before any service.
• Capacitors can retain dangerous voltage even when unplugged—discharge safely using an insulated discharge tool.
• Follow the appliance service manual for correct removal and wiring; replace with the exact OEM part.

This replacement capacitor with internal resistor helps stabilize control circuits and assist motor start in compatible appliances, restoring reliable electrical performance and preventing intermittent operation. What it does

• Provides the capacitance needed for motor start/run and helps suppress electrical noise in control circuits.
• Supports steady voltage during startup to reduce motor humming or failure to start.
• Can resolve intermittent operation, erratic control behavior, or startup delays when failing.
• Contains an internal bleed/resistor to safely discharge stored energy and reduce residual charge risk.

• Disconnect power at the breaker and unplug the appliance before accessing electrical components.
• Capacitors can hold a charge — discharge safely and use insulated tools.
• Handle carefully to avoid damage from bending leads or crushing the housing.

Refrigerator not cooling or compressor not starting? This overload relay kit protects the compressor from electrical overload. Moderate DIY repair.

Fix a refrigerator compressor that won't start or runs hot with this overload protector. Protects the compressor from electrical damage. DIY repair.

Refrigerator compressor buzzing but not starting? This start relay and overload protector fixes clicking sounds and warm temps. DIY-friendly repair.

Compressor won't start or cycles on and off? This overload protector prevents motor damage from electrical surges. Direct replacement part.

Refrigerator won't cool or compressor won't start? This compressor start relay and overload protector fixes cooling failures. Simple DIY repair.

Fix a refrigerator that won't cool or run with this PTC starter relay. Controls compressor startup. Common repair for cooling failures. Easy install.

If your air conditioner won't turn on or cycles incorrectly, the switch may be faulty. This direct replacement restores proper operation.

Refrigerator not cooling or clicking every few minutes? A failed compressor overload prevents starting. This protector restores normal cooling operation.

Fix a refrigerator that won't cool or run with this compressor overload protector. Prevents motor damage from electrical surges. Basic repair.

If your microwave won't heat food or hums loudly, the high voltage capacitor may have failed. This electrical component stores energy for the magnetron.

If your refrigerator won't start or compressor clicks but doesn't run, the start relay may have failed. This part typically takes 15-30 minutes to replace.
