Start Capacitor Parts

Refrigerator not cooling or compressor clicking? This start relay and overload protector helps the compressor start properly. Common DIY repair in 30 minutes.

Microwave not heating food? The high voltage capacitor often fails alongside the diode or magnetron. DIY repair in 1-2 hours can save hundreds.

If your microwave won't power on or runs intermittently, a faulty capacitor may be the cause. This part stores electrical charge for the magnetron.

Fix a washer dryer combo that won't start, stopped mid-cycle, or produced a burning smell. This capacitor restores power to the motor. DIY repair.

This line filter reduces electrical interference and helps protect the appliance's control electronics from power-line noise for more reliable operation. It's a direct-replacement electrical filter used inside the appliance power circuit. What it does:

• Filters incoming power to reduce electrical noise and interference that can affect controls
• Helps prevent intermittent or erratic behavior of electronic control boards
• Protects sensitive electronics from voltage spikes and line disturbances

• One line filter

• Disconnect power to the appliance before servicing to avoid shock or injury
• Access typically requires removing an access panel; keep track of fasteners and wire locations
• Handle electrical terminals carefully; ensure secure, correct reconnections

This run capacitor helps the appliance motor keep steady torque during operation for reliable performance and smoother starts. It replaces a worn or failed capacitor to restore normal motor function and reduce abnormal noise or cycling. What it does:

• Provides continuous phase shift and stored energy to help the motor run efficiently
• Common symptom: motor hums but won't start or has weak starting torque
• Common symptom: motor runs intermittently, stalls, or cycles on and off
• Common symptom: unusually noisy motor operation or reduced performance

• Disconnect power to the appliance before accessing or replacing the capacitor
• Capacitors can hold charge—discharge safely
• Match terminal types and mounting style to the original part for proper fit

Fix an air conditioner that won't start or run with this relay switch. Common solution for compressor or fan motor failure. Direct replacement part.

Air conditioner won't turn on or power button not responding? This main switch controls your AC's power operation. Standard repair for most models.

Air conditioner won't start or trips breaker? This compressor overload protector interrupts power during overheating or excessive current draw to prevent damage.

Fix a refrigerator that won't cool or runs constantly with this compressor start relay. Simple replacement takes 15-30 minutes with basic hand tools.

Refrigerator not cooling or compressor not starting? This overload protector prevents compressor failure by stopping excessive current draw. DIY repair.
